                                    PART I

ITEM 1.  BUSINESS
- -----------------
General

     Aquarion Company ("Aquarion") is a holding company whose subsidiaries
are engaged both in the regulated utility business of public water supply
and in various nonutility businesses.

     Aquarion's utility subsidiary, Bridgeport Hydraulic Company ("BHC"),
and its subsidiary, Stamford Water Company ("SWC", together with BHC, the
"Utilities") collect, treat and distribute water to residential, commercial
and industrial customers, to other utilities for resale and for private and
municipal fire protection.  The Utilities provide water to customers in 22
communities with a population of approximately 492,000 people in Fairfield,
New Haven and Litchfield Counties in Connecticut, including communities
served by other utilities to which water is available on a wholesale basis
for back-up supply or peak demand purposes through the Regional Pipeline. 
BHC is the largest investor-owned water company in Connecticut and, with
its SWC subsidiary, is among the 10 largest investor-owned water companies
in the nation.  The Utilities are regulated by several Connecticut
agencies, including the Connecticut Department of Public Utility Control
(the "DPUC").

     Aquarion is also engaged in various nonutility activities.  The
Company conducts an environmental testing laboratory business through its
Industrial and Environmental Analysts group of subsidiaries (collectively,
"IEA").  IEA performs testing to determine the nature and quantity of
contamination in sampled materials, including hazardous wastes, soil, air
and water.  IEA provides a range of environmental analytical testing
capabilities, including routine and customized analysis of organic and
inorganic contaminants.  IEA's testing services are conducted at six
regional environmental testing laboratories in Connecticut, Florida,
Illinois, Massachusetts, New Jersey and North Carolina.  IEA's laboratories
are subject to governmental regulation at both state and federal levels. 
IEA's clients include engineering consulting firms, industrial and
commercial corporations and federal, state and local governmental entities. 
The laboratories located in North Carolina, New Jersey and Connecticut
participate in the U.S. Environmental Protection Agency's Contract
Laboratory Program.

     Aquarion owns Timco, Inc. ("Timco"), a small forest products and
electricity cogeneration company based in New Hampshire.  At Timco's
sawmill complex, lumber is cut and packaged for sale to wholesalers and
retailers.  The cogeneration plant produces electricity which is sold to a
public utility and low cost steam for drying the lumber and heating some of
the sawmill buildings.  Aquarion Company is also engaged in several small
utility management service businesses through its Hydrocorp, Inc.
("Hydrocorp") and Aquarion Management Services, Inc. ("AMS") subsidiaries
and owns Main Street South Corporation ("MSSC"), a small real estate
subsidiary formed in 1969 to assist the Utilities in marketing surplus
land.
                                   3


     The Company was incorporated in Delaware as The Hydraulic Company in
1969 to become the parent company to BHC, a Connecticut corporation founded
in 1857.  The corporate name was changed to Aquarion Company in April 1991. 
The Company's executive offices are located at 835 Main Street, Bridgeport,
Connecticut  06601-2353 and its telephone number is (203) 335-2333.

Recent Developments

     Rates.  In filing its rate application with the Connecticut Department
of Public Utility Control (DPUC) in February 1993, BHC had requested a
35 percent water service rate increase designed to provide a $17,500,000
increase in annual water service revenues and a return on common equity of 
12.75 percent.  Prior to the final decision, BHC lowere
request by a total of $1,400,000 by restructuring long-term debt to reduce
annual interest costs and by reducing property taxes and other
miscellaneous expenses.  The request included the replacement of a
construction work in progress water service rate surcharge (CWIP rate
surcharge) previously granted to BHC pursuant to DPUC regulations to
recover 90 percent of the carrying costs of capital used in its Easton Lake
Filtration Construction Project mandated by the federal Safe Drinking Water
Act of 1974 (the "SDWA").  During 1993 and 1992, BHC derived revenues of
$1,937,000 and $1,532,000, respectively, from the CWIP rate surcharge. 
Effective August 1, 1993, the DPUC awarded BHC a 20.7 percent water service
rate increase designed to provide a $10,400,000 annual increase in revenues
and a 11.6 percent return on common equity.  The DPUC approved a 22.5
percent water services rate increase for SWC effective August 28, 1991,
designed to increase annual revenues by $2,276,000 and provide a 12.85
percent return on its common equity.  Effective January 1, 1991, BHC was
awarded a 15 percent rate increase designed to increase annual revenues by
$6,983,000 and provide a 13.25 percent return on its common equity.  There
is no certainty that any given rate increase will produce the intended
level of revenues or the allowed return on equity.  See "Public Water
Supply--Rates and Regulation."

     Pending Utility Acquisition.  Aquarion has proposed to acquire The New
Canaan Water Company and Ridgefield Water Supply Company for Aquarion
common stock with a market value of $3,500,000 on or about the closing
date.  The acquisition and a related property exchange have been approved
by the DPUC but remain contingent upon certain other regulatory approvals
satisfactory to the parties.  Proceedings to obtain the regulatory
approvals are pending.  The parties have agreed to extend their acquisition
agreement and the related property exchange agreement until March 31, 1994. 
There is no certainty that the parties will agree to further extensions if
the transaction has not closed by that time.  See "Industry Segment
Information."

     Sale of Facilities.  On March 15, 1993 IEA sold its Vermont laboratory
which performed qualification and certification of and consulting for high
purity gas delivery systems and ultrapure water systems, as well as some
microbiological testing.  In addition, in October 1993 IEA sold the assets
of its air testing division to TRC, Inc. of Hartford, Connecticut.  See
"Environmental Laboratories."

     Other.  Native Americans who allege that they constitute the Golden
Hill Paugussett Tribe of Indians (the "Paugussett Indians") have taken an
appeal to the U.S. Court of 

                                       4


Appeals for the Second Circuit for the
dismissal by the U.S. District Court in Connecticut of their suit seeking
to restore claimed rights to certain lands in various towns in Fairfield
and New Haven Counties.  Newspaper reports during 1993 indicated that they
have announced plans to claim further lands, including all land in the
municipalities of Monroe, Shelton and Trumbull.  BHC, which has not been
named as a defendant to date, owns land in these communities, including
land it considers surplus.  It is not possible at this time to determine
whether any further suit will be filed or, if so, whether BHC will be named
a defendant, nor is it possible to determine what effect, if any, the
filing of any such suit might have on the marketability of real property in
these communities or, should the Paugussett Indians prevail, whether there
would be any effect on the operations of BHC.

Utility Construction Program

     The Utilities are engaged in a continuing construction program
mandated by legislative and regulatory requirements, as well as for
infrastructure replacements.  The Utilities expended $16,300,000,
$21,727,000 and $13,969,000 in 1993, 1992 and 1991, respectively, for plant
additions and modifications of existing plant facilities, excluding an
allowance for funds used during construction ("AFUDC").  The expenditures
were made primarily for installations of water mains, service connections 
and meters and such special projects as the Easton Lake 
and the Litchfield Division supply and distribution system improvements.

     Utility capital expenditures for 1993 aggregated $16,300,000 and
budgeted expenditures for 1994, most of which management believes should
not be postponed, are approximately $34,200,000. Approximately half of
these expenditures will be devoted to compliance with the SDWA, which
requires filtration or alternative water treatment measures for BHC's
major, unfiltered surface water supplies.  The total capital cost of water
filtration or alternative treatment measures for such supplies through
December 31, 1993 was approximately $28,400,000, of which $26,800,000
related to construction of the Easton Lake filtration facility.  Management
estimates that the total of such costs from 1994 through 1996 will
approximate $50,000,000, without adjustment for inflation, including
$15,300,000 expected to be incurred in 1994.  Approximately $48,000,000 of
the projected 1994 through 1996 water treatment costs will be incurred in
construction of the filtration facility for the Hemlocks reservoir.  The
remaining $2,000,000 of estimated filtration expenditures over the next
four years is budgeted for SDWA-related facilities for BHC's Lakeville and
Norfolk Reservoirs.  Part of the cost associated with the Hemlocks facility
is expected to be offset by CWIP rate surcharges which, at the DPUC's
discretion, permit the recovery of 90 percent of the carrying cost of
capital used in construction of SDWA-mandated water treatment facilities. 
Management cannot predict whether future federal, state or local regulation
may require additional capital expenditures.

     The Company's ability to finance its future construction programs
depends in part on future rate relief and the level of CWIP rate
surcharges.  In light of the Company's substantial need for additional
funds, the Company will need additional debt and equity capital to finance
future utility construction.  See "Item 7. Management's Discussion and
Analysis of Financial Condition and Results of Operations - Capital
Resources and Liquidity" and "Business--Public Water Supply--Rates and
Regulation."

Industry Segment Information

     The Company's operations are grouped into four industry segments:
public water supply; environmental laboratories and utility management
services; forest products; and real estate. The consolidated operating
revenues of the Company for the year ended December 31, 1993 were derived
from the following sources: 66 percent from public water supply, 22 percent
from environmental laboratories and utility management services, 12 percent
from forest products, and less than 1 percent from real estate, including
both MSSC and surplus utility land sales. For additional information
concerning each segment for each of the years ended December 31, 1993, 1992
and 1991, see "Note 11" of "Notes to Consolidated Financial Statements" and
"Item 7.  Management's Discussion and Analysis of Financial Condition and
Results of Operations."

Public Water Supply

     Service Area.  The Utilities are engaged in the collection, treatment
and distribution of water for public and private use to residential,
commercial, and industrial users, and for municipal and private fire
protection services in 22 communities in parts of Fairfield, Litchfield and
New Haven counties in Connecticut. The Utilities also sell, as requested,
water for redistribution to customers of the First and Second Taxing
Districts' Water Departments of the City of Norwalk, Connecticut,
Connecticut-American Water Company, and NCWC through the Southwest Regional
Pipeline in Fairfield County.


     The communities served by the Utilities as of December 31,  1993, have
a population of approximately 492,000, and the total number of customer
accounts as of that date was approximately 123,900.  The Utilities' service 
areas, primarily residential in nature, have experienced an average growth
in accounts of approximately 1 percent per year over the last ten years. 
Industrial use has declined significantly in that time period, and the
residential characteristics of the area have changed, indicating an
increase in the percentage of apartment dwellings and condominium units. 
Management does not anticipate any significant growth in residential
consumption in the foreseeable future, and expects continued decline in
industrial use.

     The operating revenues of the Utilities for the twelve months ended
December 31, 1993 were derived from the following sources:  59 percent from
residential customers, 17 percent from commercial customers, 5 percent from
industrial customers, 14 percent from fire protection customers, and
5 percent from other sources.

     Seasonality.  The business of the Utilities is subject to seasonal
fluctuations and weather variations.  The demand for water during the
warmer months is generally greater than during the cooler months, primarily
due to additional water requirements of industrial and residential cooling
systems, and various private and public outdoor uses such as lawn and golf
course sprinkling.  From year to year and season to season, demand will
vary with rainfall and temperature levels.

                                     6



     Water Supply.  Water is available from both surface and subsurface
sources.  During 1993, approximately 97 percent of the water supplied by
the Utilities was provided by impounding reservoirs, 2 percent by producing
wells and 1 percent by purchased water.  As of December 31, 1993, the
Utilities' reservoirs, well fields and interconnections with other water
utilities had an aggregate safe daily yield of 112.3 million gallons.  Safe
yield is an estimate of the supply capability during an extended drought. 
The average daily demand for water from the Utilities in 1993 was 69.3
million gallons per day ("MGD").  The reservoirs of the Utilities have an
aggregate storage capacity of 29.4 billion gallons.

     All of the Utilities' reservoirs and active wells are located on
property owned by the Utilities.  Management believes it has an adequate
water supply to satisfy the current and projected needs of its customers
within its territorial service area through at least the year 2040.  During
historical drought periods in the northeastern United States, the Utilities
have been able to accommodate the needs of their own customers and to offer
relief to supplement the supplies to neighboring communities by water sales
to utilities with which it has pipeline interconnections. Supply and
distribution needs of the Utilities undergo constant review, and the
Utilities continue to explore and develop additional ground water supplies
and study alternative surface water sources to meet anticipated future
water requirements.

     The Connecticut Water Diversion Policy Act, enacted in 1982, prohibits
any future diversions of surface or ground water without a permit from the
DEP.  Although this law "grandfathers" existing surface and ground water
supplies which existed when it was enacted, any subsequent water diversion
which might be effected by the Utilities is subject to a lengthy permit
application process and approval by the DEP.  Diversion permits granted
pursuant to this law are subject to renewal when their terms, which
typically run from five to ten years, expire.

     Rates and Regulation.  The Utilities are incorporated under and
operate as public water utilities by virtue of authority granted by Special
Acts adopted by the Connecticut legislature (the "Acts").  These Acts have
granted a non-exclusive franchise, unlimited in duration, to provide public
water supply to private and public customers in designated municipalities
and adjacent areas.  The Acts also authorize the Utilities to lay their
mains and conduits in any public street, highway, or public ground; to use
the water of certain rivers, streams, or other waters in Fairfield,
Litchfield and New Haven counties and from certain locations along and in
the Housatonic River and its tributaries, subject to such consents and 
approvals as may be required by law; and to exercise the po
domain in connection with lands, springs, streams or ponds and any rights
or interests therein which are expedient to or necessary for furnishing
public water supply.  In the event of the exercise of such condemnation
powers, the Utilities must pay appropriate compensation to those
injuriously affected by such taking. 

     The Utilities are subject to regulation by the DPUC, which has
jurisdiction with respect to rates, service, accounting procedures,
issuance of securities, dispositions of utility property and other related
matters.  

     Rates charged by each of BHC and SWC are subject to approval by the
DPUC.  The Utilities continually review the need for increases of water
rates, and historically have sought 

                                     7



rate relief in a timely manner in light
of increases in operating costs, additional investment in utility plant and
related financing costs, as well as other factors.  For information
concerning rate increases granted in 1993 and 1991, see "Item 1. Business.
Recent Developments, Rates.", above.



     The following table sets forth information as to rate requests by BHC
and SWC and increases granted by the DPUC in the last three rate cases.

          *    Original request of $17,500,000, or 35 percent, was
               subsequently lowered prior to the final decision by
               $1,400,000 by restructuring long-term debt to reduce annual
               interest costs and by reducing property taxes and other
               miscellaneous expenses.



               The DPUC may allow a surcharge to be applied to rates in
          order to provide a current cash return to water utilities on the
          major portions of CWIP applicable to facilities, including
          filtration plants, required for compliance with the SDWA.  See
          "Environmental Regulations."  The surcharge is adjusted
          quarterly, subject to DPUC approval, to reflect increased CWIP
          expenditures for SDWA facilities.  In connection with BHC's
          construction of filtration facilities at its Easton Lake
          Reservoir, the DPUC granted BHC an initial .94 percent CWIP rate
          surcharge in September 1990, which amount was incrementally
          increased on a quarterly basis to 7.35 percent at the time new
          rates became effective and the Easton facility became operational
          and subject to general ratemaking regulations.  There is no CWIP
          surcharge in effect at present, although BHC intends to apply for
          a CWIP surcharge with respect to its planned filtration
          facilities when appropriate. 

               Aquarion is neither an operating utility company nor a
          "public service company" within the meaning of the Connecticut
          General Statutes and is not presently subject to general
          regulation by the DPUC. DPUC approval is necessary, however,
          before Aquarion may acquire or exercise control over any
          Connecticut public service company.  DPUC approval is also
          required before any other entity can acquire or exercise, or
          attempt to exercise, control of Aquarion.

               Connecticut regulations govern the sale of water company
          land and treatment of land sale proceeds.  See "Item 2. 
          Properties."

               Environmental Regulations.  The Utilities are subject to
          regulation by the DPHAS with respect to water quality matters,
          use of water from surface and subsurface sources, the location,
          construction and operation of water supply facilities and the
          sale of certain utility property.  Plans for new water supply
          systems or enlargement of existing water supply systems also must
          be submitted to the DPHAS for approval.  The DEP is authorized to
          regulate the operations of the Utilities with respect to water
          pollution abatement, diversion of water from surface and
          subsurface sources, and the location, construction and alteration
          of dams and other water obstructions.

               The Federal Clean Water Act of 1972, as amended (the "Clean
          Water Act"), regulates for discharges of effluents into navigable
          waters.  A joint Federal and state permit system has been
          established to ensure that applicable effluent limitations and
          water quality standards are met in connection with the
          construction and operation of facilities which affect or
          discharge into state or interstate waters.

               The Utilities are subject to regulation of water quality
          under the SDWA, which provides for the establishment of uniform
          minimum national quality standards by the Environmental
          Protection Agency (the "EPA"), as well as governmental authority
          to specify the type of treatment process to be used for public
          drinking water.  EPA regulations issued pursuant to the SDWA set
          limits for, among other things, certain organic and inorganic
          chemical contaminants, odor, turbidity, microbiological
          contaminants and radioactivity.  The SDWA provides that the
          states have the primary enforcement responsibility for public
          drinking water systems, as long as the states' regulations are no
          less stringent than those adopted pursuant to SDWA.  For certain
          of these water quality standards the DPHAS has adopted
          regulations which in some instances impose standards more
          stringent than those imposed under the Federal regulations.

               EPA regulations pursuant to SDWA include the Surface Water
          Treatment Rule ("SWTR"), the Total Coliform Rule ("TCR") and the
          Lead and Copper Rule ("LCR").  The water treatment requirements
          of SWTR mandate the construction of filtration plants at BHC's
          Hemlocks, Lakeville and Norfolk Reservoirs.  BHC has entered into
          consent agreements with DPHAS establishing timetables for
          construction of filtration facilities at the Hemlock, Lakeville
          and Norfolk reservoirs and penalties if the facilities are not
          completed within such timetables.  The Hemlocks plant must be
          completed by June 29, 1998 or a $250,000 penalty will be imposed. 
          Lesser penalties apply to the smaller facilities for Lakeville
          and Norfolk, if not completed by June 29, 1997 and June 29, 1996,
          respectively.  The Company anticipates that it will be able to
          meet the construction timetables.  The TCR affects the Utilities
          by the imposition of requirements for additional biological
          sampling and monitoring.  The stringent requirements of the TCR
          may also result in increased public notification relating to
          water quality.  The LCR establishes corrosion control techniques
          and requires monitoring to determine compliance with prescribed
          lead and copper levels in drinking water.  If such levels are
          exceeded, a multi-year program involving additional monitoring,
          public notification, state-supervised corrosion control and
          treatment and replacement of lead service lines could result. 
          After the first two required testing periods, the Utilities were
          found to be 

                                       9



          in compliance with the LCR.  Further SDWA-related
          regulations are anticipated for such water quality parameters as 
          organics, inorganics and disinfection by-products.  It is
          impossible to determine at this time the ultimate impact these
          regulations will have on the Utilities.

               The Company currently estimates that future capital costs of
          SWTR-mandated filtration facilities will approximate $50,000,000
          for the period 1994 through 1996, without adjustment for
          inflation, in addition to the $28,400,000 which has been expended
          through December 31, 1993, mostly for construction of the Easton
          Reservoir plant.  That plant is located in Easton, Connecticut
          and was completed in June 1993 at an aggregate cost of
          $26,800,000.  

               Water quality tests are made continuously at all of the
          Utilities' water supply sources, and the Utilities believe they
          are in substantial compliance with regulations promulgated by the
          organic chemical, inorganic chemical, physical, and
          bacteriological standards for drinking water.  BHC has been
          voluntarily monitoring for giardia and cryptosporidium, water
          quality concerns addressed by the SWTR.  Positive samples (low
          levels) have been found in the three unfiltered surface water
          supplies.  When the filtration plants become operational, they
          will remedy such concerns, which are now being addressed by
          interim treatment techniques approved by the DPHAS.

               Connecticut has established seven public water supply
          management areas to coordinate the comprehensive planning of
          public water systems and provide for the centralized regulation
          by the DPHAS of water resources for water supply and other public
          purposes. Each area has a water utility coordinating committee
          ("WUCC") comprised of representatives of the various public water
          systems and regional planning agencies in the area.  BHC
          operations fall under four of the State's seven WUCCs, and SWC
          operations fall under two WUCCs.  Each WUCC is required to
          establish exclusive service areas for each public water system in
          the area.  The DPHAS is authorized to resolve any disagreements
          among members of the respective committees.  It is not possible
          at this time to predict the full impact on the Utilities of the
          WUCC system and the associated regulations and proceedings.

               Aquifer protection legislation in Connecticut requires each
          water utility to conduct extensive groundwater data collection
          and groundwater mapping of critical wellfield areas.  The DEP is
          also proposing land use regulations within these critical areas.
          The proposed legislation mandates that each municipality
          designate an aquifer protection agency to regulate land use in
          these areas. Finally, the DEP, in consultation with the DPHAS and
          DPUC, is preparing guidelines for acquisition of lands for
          proposed public water supply wellfields.  Regulations are still
          being prepared for this program and the effect of this
          legislation and related regulations cannot be determined at this
          time.  If BHC were required to purchase additional land around
          its wellfields, the cost could be substantial.

               Developments with respect to the identification and
          measurement of various elements in water supplies and concern
          about the effect of such elements on public health, together with
          possible contamination of water sources, may in the future
          require the Utilities to modify all or portions of their various
          water supplies, to develop replacement supplies or to implement
          new treatment techniques.  Any such developments would
          significantly increase 

                                     10




          the Utilities' operating costs and capital
          requirements.  The Company expects that all such expenditures and
          costs should ultimately be recoverable through rates for water
          service, but there can be no assurance that this will be the
          case. 

                Certain dams owned by the Utilities are subject to
          inspection under the National Dam Inspection Act as well as the
          Connecticut Dam Registration Act, and dams owned by SWC in New
          York are subject to inspection by the New York State Department
          of Environmental Conservation.  The Utilities own 29 dams, 16 of
          which are subject to federal inspection.  Although certain
          modifications and further studies have been required, no material
          problems with respect to these dams have been reported to the
          Company.

               The Utilities are required to obtain permits from the DEP
          for the location, construction or alteration of any dam or
          reservoir, and to secure the approval of the DEP for the
          diversion and use of water from any surface or ground source for
          public use.  The Utilities have taken all compliance actions
          required to date.

               SWC may be subject to health, safety and environmental
          regulation by various state and local authorities in New York
          State with respect to its properties located in New York.  SWC
          does not provide water to any customers in New York.  The leasing
          or sale of land around reservoirs, wellfields and some streams 
          may be restricted by various Connecticut statutes and
          regulations.  See "Item 2.  Properties."

          Environmental Laboratories

               Laboratories.  The Company conducts an environmental testing
          laboratory business through IEA, which operates six laboratories
          in Connecticut, Florida, Illinois, Massachusetts, New Jersey and
          North Carolina through six corporate subsidiaries.  IEA believes
          that it is among the twenty largest environmental testing
          laboratory businesses in the country.  IEA is headquartered at
          its Cary, North Carolina facility.

               Environmental laboratories provide data to customers
          concerning the nature and quantity of contaminants or hazardous
          substances present in samples.  IEA offers a range of
          environmental analytical services, including routine and
          customized testing of hazardous wastes, soil, air and water.
          Additionally, IEA offers mixed waste/radiological testing at its
          North Carolina laboratory.  IEA also provides asbestos testing
          and sample collection services.

               Quality Control.  The ability to deliver accurate and
          precise test results consistently is essential to a successful
          laboratory, and testing samples must meet rigorous
          chain-of-custody requirements and testing protocols to enable the
          test results to be used as evidence in legal or regulatory
          proceedings.  IEA performs internal quality assurance reviews to
          monitor consistent performance.  IEA is certified in over 20
          state-operated certification programs and, through its
          laboratories in North Carolina, New Jersey and Connecticut, is an
          active participant in the EPA's Contract Laboratory Program
          ("CLP").  In order to qualify for the CLP, the laboratories must
          satisfy stringent quality control standards, and are subject to
          quarterly performance evaluations.

                                      11



               Technology.  IEA has invested in sophisticated analytical
          testing equipment needed to process a large volume of tests with
          accurate results.  IEA laboratories are equipped with Gas
          Chromatography/Mass Spectrometry instruments, which identify
          specified organic and inorganic chemical compounds within a
          sample by means of electron beam "fingerprinting." IEA owns
          chromatograph instruments, which are used extensively to perform
          organics testing.  IEA laboratories contain inductively coupled 
          plasma instruments and atomic absorption units for organic analysis.
          analysis.  IEA laboratories perform wet-chemistry tests for
          general chemistry parameters and also offer a range of microscopy
          services including asbestos analysis.   

          Laboratory Employees.  Experienced personnel qualified in
          the use of the instruments and related computer systems used by
          IEA are critical to its operations.  IEA has a staff of
          approximately 300, which includes 183 scientists and technicians. 
          IEA's laboratory services are marketed by a field and in-house
          sales staff who are supported by IEA's Client Service Department
          as well as by IEA's scientific and technical staff.  The testing
          laboratory industry, as well as the environmental services
          industry as a whole, suffers from a shortage of qualified staff
          at all skill levels.  As a result, the market for trained
          technical staff is very competitive, and IEA occasionally
          experiences personnel shortages.

               Customers.  During 1993, IEA serviced approximately 1,500
          customers.  No single customer represented 10 percent or more of
          IEA's revenues during that period.  IEA's broad client base
          includes consulting and engineering firms, public and private
          water companies, large and small industrial and high-tech
          companies, Federal government agencies, including the EPA, and
          various state and local government bodies, including state
          environmental departments, municipalities and waste treatment
          facilities.

               Competition.  The environmental testing business is highly
          competitive.  Its participants compete primarily on the basis of
          price and service.  Many customers view environmental testing as
          a commodity, and price for them is the most important factor in
          purchasing decisions.  Following a period of rapid growth, the
          environmental testing business is now characterized by
          significant overcapacity.  As a result of these factors,
          operating margins tend to be low.

               Estimates of the number of commercial laboratory companies
          range between 1,000 and 1,500, although IEA believes that the
          thirty largest companies account for approximately 50 percent of
          industry revenues.  Most laboratory companies are
          single-laboratory operations serving a local market.  As the
          environmental services market has matured over the past 20 years,
          the trend has been toward consolidation and larger laboratory
          companies that operate several laboratories.  This trend has been
          driven, in part, by the increasing sophistication and expense of
          laboratory equipment.  In addition, larger laboratory companies
          can offer a wider variety of services and equipment.  Some
          customers, particularly larger companies with operations in
          multiple locations, prefer to deal with larger laboratory
          companies.  In addition, some environmental service businesses
          operate in-house laboratories that exclusively service their own
          environmental testing needs.  IEA's competitors include larger
          companies that possess greater financial resources than the
          Company.  The three IEA laboratories that participate in the CLP
          compete with approximately 50 other laboratory companies that bid
          for such EPA work. 

                                       12


                Regulatory Background.  Federal and state environmental laws
          and regulations have been the primary force driving the
          environmental testing laboratory market.  The proliferation of
          environmental regulations over the past two decades has required
          increasingly sophisticated analysis and remediation of a growing
          range of environmental hazards.  The environmental services
          industry has grown rapidly in response to regulatory demands for
          tests that reveal the nature and quantity of any contamination
          caused during the handling, use and transportation of hazardous
          substances, the treatment, storage and disposal of wastes, and
          the remediation of contaminated sites.  As advances in technology
          have continued to make greater testing sophistication possible,
          regulations have often been revised to require those more
          sophisticated tests.

               Environmental Regulation.  IEA receives and uses various
          small quantities of hazardous chemicals in its operations, and is
          a licensed hazardous waste handler.  IEA operates under federal
          and, as applicable to the states in which various IEA
          laboratories operate, various state environmental laws and
          regulations that subject parties handling hazardous wastes to
          potential liabilities for non-compliance, in addition to possible
          civil and criminal penalties.

               Contract Terms.  IEA's client contracts generally contain
          provisions which may impose financial penalties for inaccurate or
          late test results.  Contracts with governmental and private
          sector clients regularly contain liquidated damage or penalty
          provisions which reduce the amount paid if a test is delivered
          late.

               Seasonality.  IEA's business is affected by seasonality.
          IEA's busiest period is during the late spring, summer and early
          fall, when sampling and construction activity is at its peak.
          Sampling, and therefore the related testing, falls off for large
          parts of IEA's service area during the winter months because of
          frozen ground and water and accumulations of snow in some parts
          of the country.

          Utility Management Services

               The Company, through Hydrocorp and its AMS subsidiary,
          provides clients with an integrated range of utility management
          services, including contract management and operations,
          information services, water and wastewater billing and
          collections and various engineering, operations and management
          consulting services.  AMS clients are private and municipal water
          and wastewater utilities, including municipal systems engaged in
          privatization initiatives.  

               Hydrocorp also has minority interests in small businesses
          which provide security consulting services and automated mapping
          and facilities management services to utilities, industry,
          municipalities and government agencies.

               The utility management services businesses are highly
          competitive, on the basis of service and price.

                                     13



          Forest Products

               The Company is engaged in the forest products industry
          through Timco, which has operations in New Hampshire consisting
          of a sawmill complex and a wood-waste electricity cogeneration
          plant. The sawmill complex processes and markets kiln-dried,
          finished Eastern White Pine and other lumber.  The product is
          used in the remodeling and do-it-yourself markets and, to a 
          lesser extent, in the construction of new homes.  
          in the Northeast and Mid-Atlantic regions through lumber
          wholesalers, distributors and, in some instances, directly to
          retailers.  Wholesalers and distributors, in turn, sell the
          product to the construction trade and to retail outlets.  Timco
          obtains the timber used in its products from independent loggers
          and from purchased timber rights.  A four megawatt electricity
          cogeneration plant is located at the sawmill complex. 
          By-products of the cogeneration plant include low cost steam for
          drying lumber and heating some of the sawmill buildings.  

               Electricity produced at Timco's cogeneration plant is sold
          to Public Service Company of New Hampshire ("PSNH") under a
          long-term rate order of the New Hampshire Public Utilities
          Commission ("PUC") applicable to Small Power Producers (the "Rate
          Order").  In January 1988, PSNH sought protection under Chapter
          11 of the U.S. Bankruptcy Code.  PSNH emerged from bankruptcy in
          June 1991, managed by Northeast Utilities ("NU") and was acquired
          by NU in June, 1992 after NU's reorganization plan received the
          requisite approvals.  The plan provided that after the merger, NU
          would seek to restructure the Rate Order.  Negotiations to
          restructure the Rate Order have produced a tentative agreement
          between PSNH and several small power producers, including Timco,
          which has been submitted to the PUC for approval.  Terms of the
          agreement call for PSNH to pay Timco up to $8.6 million depending
          on the timing of regulatory approval and the date of payment, in
          exchange for the assignment of the Rate Order to PSNH and a
          release of PSNH's obligations to buy power from Timco. There is
          no assurance that it will be approved, nor is there any way to
          predict what action the PUC might take if it does not approve the
          agreement.  Any substantial reduction in Timco's electricity
          revenues ($3,515,000 in 1993) which may result from a
          restructuring of the Rate Order would have an adverse impact on
          the Company's forest products operations.

               Traditionally, the demand for Timco's lumber is lower in the
          winter months and inventories are built up in anticipation of the
          busier spring and summer season.  The lumber products industry is
          very competitive, primarily on the basis of price.  Timco faces
          competition on the basis of price from domestic and foreign
          forest product companies, many of which have greater resources
          than the Company.

          Real Estate

               The Company treats real estate as a separate business
          segment in order to distinguish the earnings impact from sales of
          surplus utility land from the results of Utility operations.  For
          a discussion of the surplus non-watershed land which the
          Utilities intend to market as appropriate, see "Item 2. 
          Properties."  

                                  14


          Employees

               As of December 31, 1993, the Company employed approximately
          695 persons on a full time basis, including 289 in the Public
          Water Supply business, 306 in the Environmental Laboratories and
          Utility Management Services business and 100 in the Forest
          Products business.  None of the Company's employees are covered
          by collective bargaining arrangements, and the Company believes
          its relations with its employees are satisfactory.

          Executive Officers

               For information concerning the Company's executive officers,
          see "Item 10.  Directors and Executive Officers of the 
          Registrant".


          ITEM 2.  PROPERTIES
          -------------------

          The Company

               BHC owns a 20,000 square foot headquarters building and a
          44,370 square foot Operations Center in Bridgeport, and leases an
          additional 22,000 square feet of office, laboratory and garage
          space in Bridgeport for utility operations.  SWC owns its
          13,618 square foot headquarters and operations facility in
          Stamford, Connecticut.  Aquarion owns nonutility land totaling
          approximately 99 acres in Easton and Litchfield, Connecticut.

          Property

               At December 31, 1993, BHC owned in the aggregate 11 active
          reservoirs and approximately 1,640 miles of water mains, of which
          approximately 77 miles have been laid in the past five years.  In
          addition, SWC owned 5 active reservoirs at year end.  The rights
          to locate and maintain water transmission and distribution mains
          are secured by charter, easement and permit and are generally
          perpetual.  Water is delivered to the distribution system from
          four major and several smaller reservoirs and forty-two producing
          wells.  Eight additional reservoirs are used for storage purposes
          and are interconnected with the distribution reservoirs.  

               BHC owns two dual media filtration plants for treatment of
          its Trap Falls and Easton Lake reservoir systems, which plants
          have capacities of 25 and 20 MGD, respectively.  SWC owns a 24
          MGD rapid-sand and activated-carbon filtration plant for
          treatment of its entire reservoir system.

               BHC owns approximately 19,000 acres of real property located
          in Fairfield, New Haven, and Litchfield Counties, Connecticut,
          most of which consists of reservoirs and surrounding watershed.
          All but 1,360 specified acres of such property are subject to the
          first lien arising under the BHC Indenture securing its First
          Mortgage Bonds.  SWC owns approximately 2,400 acres of real
          property located in Stamford and New Canaan, Connecticut, and in
          Pound Ridge and Lewisboro, New York, which consist almost

                                   15



          exclusively of reservoirs and surrounding watershed, pumps,
          standpipes and building facilities.  

               The DPHAS regulates public water company lands according to
          a three-tiered classification system.  Class I lands cannot be
          sold, leased or transferred.  The DPHAS may authorize a transfer
          or change in use of Class II lands only upon a finding that there
          will be no adverse impact upon the public water supply and that
          any use restrictions required as a condition of transfer are
          enforceable against subsequent owners and occupants of the lands.
          Class III lands, which are non-watershed, are not presently
          subject to regulation by the DPHAS.  BHC has identified
          approximately 2,300 acres of land it believes are surplus to its
          water supply needs, and therefore would qualify as Class III
          land.  All of this Class III land, which includes approximately
          570 acres which have never been in rate base, is available for
          sale, although all of it may not be marketable. Up to 530
          additional acres could become available if the DPHAS approves the
          abandonment of a former reservoir system in New Haven County and
          reclassifies existing watershed property as Class III land, as
          requested by the Company.

               Real property may not be sold or transferred by a water 
          utility without the prior approval of the DPUC an
          with other restrictions imposed by Connecticut law.  State laws
          and regulations govern, among other things, to whom certain water
          company lands may be transferred, with preference given to other
          water companies, the municipality in which the property is
          located and the State of Connecticut, in that order.
          Additionally, the disposition of the proceeds of any permissible
          sale is subject to state law.

               Until changed by statute in 1988, it had been the practice
          of the DPUC to apply gains from the sale of surplus water company
          land that had ever been in the rate base as an offset against
          operating expenses, thereby substituting profits from the sale of
          such land for revenues which would otherwise be provided through
          rates.  Legislation enacted in 1988, the Equitable Sharing
          Statute, required the DPUC to "equitably allocate" the economic
          benefits of the net proceeds from the sales of Class III land
          which was previously in the utility's rate base between the
          Company's ratepayers and its shareholders. Ratepayers do not
          share in gains from the sale of land which has never been in rate
          base.

               The Equitable Sharing Statute was clarified by a 1990
          amendment which provides that the economic benefits from the sale
          of former-rate-base, Class III land which promotes a perpetual
          public interest in open space or recreational use shall be
          allocated "substantially in favor" of shareholders when
          25 percent or more of the land sold is to be used for open space
          or recreational purposes.

               Two decisions involving 1990 land sales, resulted in
          allocations of the respective gain on the sales of 75 percent and
          43 percent, respectively, to BHC's shareholder.

               In November 1993 the DPUC gave BHC approval to sell 25.78
          acres of surplus, off-watershed land in Shelton, Connecticut. 
          BHC plans to subdivide the land into eleven building lots.  BHC
          also received approval from the DPUC in December 1993 to sell
          34.55 acres of surplus, off-watershed land in Weston,
          Connecticut.  BHC plans to subdivide the land into ten building
          lots.  Each case involves former rate base land, and 25 percent of 

                                      16



          the land to be sold will be conveyed to the host municipality
          to be preserved as open space.  Under the terms of both
          decisions, approximately two-thirds of the net proceeds from the
          land sales will be allocated to shareholders and the remaining
          one-third allocated to ratepayers through amortization into BHC's
          rate base over a five year period.  All such net proceeds must be
          used for reinvestment in utility plant.

               The Company leases all of its laboratory facilities, except
          for the Massachusetts laboratory, which it owns.  Aquarion owns
          50 percent of Key Partners III, a partnership which owns IEA's
          North Carolina laboratory and headquarters facility.  The
          smallest of IEA's laboratories occupies approximately
          6,750 square feet.  The largest, located in Cary, North Carolina,
          occupies approximately 30,000 square feet.  The Company believes
          that the laboratory facilities owned or leased are adequate for
          its present and anticipated future needs and that the amounts
          paid for all the leases into which it has entered are reasonable.

          STOCKHOLDER MATTERS
          -------------------

               Page 45 of the Company's Annual Report to Shareholders for
          the year ended December 31, 1993 is incorporated by reference
          herein pursuant to Rule 12b-23 of the Securities and Exchange Act
          of 1934 (the "Act") and to Instruction G(2) to Form 10-K.

               Aquarion has declared and paid quarterly dividends on its
          common stock without interruption since its organization in 1969,
          and prior thereto, BHC paid dividends annually on its common
          stock without interruption since 1890.  Dividends, when declared,
          are normally paid on the 30th day of January, April, July and
          October.

                                      17



               The earnings of Aquarion are derived from its investments in
          its subsidiaries, particularly BHC.  Aquarion's future ability to
          pay dividends to holders of its Common Stock is dependent upon
          the continued payment by BHC of dividends to Aquarion.  BHC's
          ability to pay dividends will depend upon timely and adequate
          rate relief, compliance with restrictions under certain of the
          BHC debt instruments and other factors.  In addition, no
          dividends on BHC's common stock can be paid during any period in
          which BHC's preferred stock dividends are in arrears.

               Dividends on Aquarion common stock can be paid only out of
          net profits and surplus of the Company.  Aquarion's ability to
          pay dividends is further restricted by the terms of Aquarion's
          8 1/2 percent unsecured Senior Notes due January 1994 , which
          were replaced by a 5.95% unsecured Senior Note due January 1999
          and 7.8 percent unsecured Senior Notes due June 1997 (the
          "Aquarion Notes").  As of December 31, 1993, the applicable
          restrictions would have permitted payment of additional dividends
          on Aquarion's common stock of up to $31,000,000.

               While Aquarion's Board of Directors intends to continue the
          practice of declaring cash dividends on a quarterly basis, no
          assurance can be given as to future dividends or dividend rates
          since they will be determined in light of a number of factors,
          including earnings, cash flow, and Aquarion and BHC's financial
          requirements. See "Item 7.  Management's Discussion and Analysis
          of Financial Condition and Results of Operations--Capital
