Item 1.  Financial Statements

                    INTRODUCTION TO THE FINANCIAL STATEMENTS

         The unaudited interim consolidated financial statements included herein
have been prepared by Calgon Carbon Corporation (the Company), without audit,
pursuant to the rules and regulations of the Securities and Exchange Commission.
Certain information and footnote disclosures normally included in annual
financial statements prepared in accordance with accounting principles generally
accepted in the United States of America have been condensed or omitted pursuant
to such rules and regulations. Management of the Company believes that the
disclosures are adequate to make the information presented not misleading when
read in conjunction with the Company's audited consolidated financial statements
and the notes included therein for the year ended December 31, 2001 filed with
the Securities and Exchange Commission by the Company in Form 10-K.

         In management's opinion, the unaudited interim consolidated financial
statements reflect all adjustments, which are of a normal and recurring nature,
which are necessary for a fair presentation, in all material respects, of
financial results for the interim periods presented. Operating results for the
first nine months of 2002 are not necessarily indicative of the results that may
be expected for the year ending December 31, 2002.

5.   Segment Information:

                                        7



     The Company has four reportable segments: Activated Carbon, Service,
     Engineered Solutions and Consumer. These reportable segments are strategic
     business units which offer different products and services. The Company
     evaluates segment performance based primarily on economic profit (as
     defined by the Company) and operating income.

     The Activated Carbon segment manufactures granular activated carbon for use
     in applications to remove organic compounds from liquids, gases, water and
     air. The Service segment consists of reactivation of spent carbon and the
     leasing, monitoring and maintenance of mobile carbon adsorption equipment.
     The Engineered Solutions segment provides solutions to customers' air and
     water process problems through the design, fabrication and operation of
     systems that utilize the Company's enabling technologies: carbon
     adsorption, ultraviolet light and advanced ion exchange separation. The
     Consumer segment brings the Company's industrial purification technologies
     directly to the consumer in the form of products and services including
     carbon cloth and charcoal products.

     An improvement in the Company's information reporting system in the second
     quarter of 2002 has allowed the Company to directly attribute, rather than
     allocate, certain inventory cost variances, distribution costs and assets,
     such as accounts receivable, to segments. As a result, the second quarter
     and June year-to-date results for 2001 have been restated to conform with
     the 2002 presentation.

6.   Derivative Instruments

     The Company accounts for its derivative instruments under Statement of
     Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
     Instruments and Hedging Activities", as amended. This standard requires
     recognition of all derivatives as either assets or liabilities at fair
     value and may result in additional volatility in both current period
     earnings and other comprehensive income as a result of recording recognized
     and unrecognized gains and losses from changes in the fair value of
     derivative instruments. As of September 30, 2002, the Company held five
     derivative instruments, four foreign exchange contracts and an interest
     rate swap agreement. None of the five derivatives received hedge accounting
     treatment under SFAS No. 133 and were marked to market through the
     Company's earnings for the nine months ended September 30, 2002.

7.   Contingencies

     On December 31, 1996, the Company purchased the common stock of Advanced
     Separation Technologies  Incorporated (AST) from Progress Capital Holdings,
     Inc. and Potomac Capital Investment Corporation.

     On January 12, 1998, the Company filed a claim for unspecified damages in
     the United States District Court in the Western District of Pennsylvania
     alleging among other things that Progress Capital Holdings and Potomac
     Capital Investment Corporation materially breached various AST financial
     and operational representations and warranties included in the Stock
     Purchase Agreement. Based upon information obtained since the acquisition
     and corroborated in the course of pre-trial discovery, the Company believes
     that it has a reasonable basis for this claim and intends to vigorously
     pursue reimbursement for damages sustained. Neither the Company nor its
     counsel can predict with certainty the amount, if any, of recovery that
     will be obtained from the defendants in this matter. Accordingly, the
     Company has not recorded a receivable for this gain contingency pending
     further developments in the litigation.

     The Company is also currently a party in two cases involving alleged
     infringement of its U.S. patent No. 6,129,893 ("893 patent") and one case
     involving alleged infringment of its Canadian patent No. 2,331,525 ("525
     patent"). Both patents are for the method of preventing cryptosporidium
     infection in drinking water. In the first case, Wedeco Ideal Horizons, Inc.
     (Wedeco) has filed suit against the Company seeking a declaratory judgment
     that it does not infringe the Company's "893 patent". This matter is
     currently pending in the United States District Court for the District of
     New Jersey. In the second case, the Company has pending litigation against
     the Town of Ontario, NY and Robert Wykle, et al. in the United

                                       9



     States District Court for the Western District of New York alleging that
     the defendant is practicing the method claimed within the "893 patent"
     without a license. The third case the Company has pending is against The
     Corporation of the City of North Bay and Trojan Technologies Inc. in
     Federal Court of Canada - Trial Division. The claim alleges that the
     defendants are practicing a method claimed in the "525 patent". Neither the
     Company nor its counsel can predict with any certainty the outcome of the
     three matters.

     The Company is involved in various legal proceedings, lawsuits, and claims,
     including employment, product warranty, and environmental matters of a
     nature considered normal to its business. It is the Company's policy to
     accrue for amounts related to these legal matters if it is probable that a
     liability has been incurred and an amount is reasonably estimable.
     Management believes, after consulting with counsel, that the ultimate
     liabilities, if any, resulting from such lawsuits and claims will not
     materially affect the consolidated results, liquidity or financial position
     of the Company.

8.   Goodwill & Intangible Assets

     In June 2001, the Financial Accounting Standards Board (FASB) issued SFAS
     No. 142, "Goodwill and Other Intangible Assets." This standard requires
     that goodwill and intangible assets with indefinite useful lives should not
     be amortized but should be tested for impairment at least annually. This
     new standard also prescribes guidelines for new disclosure requirements.
     The Company has adopted SFAS No. 142 as of January 1, 2002, as required.

     In accordance with SFAS No. 142, the Company assessed the useful lives of
     its intangible assets during the first quarter of 2002 and concluded that
     it holds no indefinite lived intangibles. As a result, no impairment test
     was required and no transition adjustment was recorded for indefinite lived
     intangibles.

     As required by SFAS No. 142, management has allocated goodwill to its
     reporting units. During the three months ended June 30, 2002, management
     completed the initial goodwill impairment test required as of January 1,
     2002 for each of its reporting units. The initial goodwill impairment test
     included determining the fair value of each reporting unit that is
     allocated goodwill and comparing that fair value to the reporting unit's
     carrying value. The Company, in its initial goodwill impairment test,
     identified one reporting unit whose carrying value exceeded its estimated
     fair value.

     The Company engaged an independent valuation specialist to estimate the
     fair value of this reporting unit. The report of the independent valuation
     specialist used a combination of methods to determine the fair value of the
     reporting unit including prices of comparable businesses, a present value
     technique and a technique using recent transactions involving businesses
     similar to the reporting unit. The reporting unit consists primarily of the
     Company's AST subsidiary that is included in the Company's Engineered
     Solutions Segment.

     As a result of the reporting unit's excess carrying value, the Company was
     required, for this reporting unit, to assign the estimated fair value to
     the reporting unit's identifiable assets (including those intangible assets
     not recorded on the reporting unit's balance sheet) and liabilities to
     determine the implied fair value of the reporting unit's goodwill and the
     amount of impairment loss as of the date of implementation, January 1,
     2002. The Company recorded a cumulative effect of change in accounting
     principle of $30.9 million (net of the tax effect of $20.1 million) at
     January 1, 2002 for its implementation of SFAS No. 142. The effect of
     adopting this change in accounting principle effective for the first
     quarter of 2002 reduced previously reported net income for the quarter
     ended March 31, 2002 by $30.9 million to a net loss of $29.6 million, basic
     net income per share by $0.80 to a basic net loss per share of $0.76, and
     diluted net income per share by $0.79 to a diluted net loss per share of
     $0.75.

9.   New Accounting Pronouncements

     The FASB issued SFAS No. 143, "Accounting for Asset Retirement
     Obligations," which addresses financial accounting and reporting for
     obligations associated with the retirement of tangible long-lived assets
     and the associated asset retirement costs. Management has not yet evaluated
     the impact of the adoption of SFAS No. 143 on the Company's financial
     statements. The Company plans to adopt SFAS No. 143 on January 1, 2003 as
     required.

     In October 2001, the FASB issued SFAS No. 144, "Accounting for the
     Impairment or Disposal of Long-Lived Assets" which addresses financial
     accounting and reporting for the impairment or disposal of long-lived
     assets. SFAS No. 144 is effective for financial statements issued for
     fiscal years beginning after December 15, 2001, and interim periods within
     those fiscal years. The Company has adopted SFAS No. 144 as of January 1,
     2002 as required with no resulting impact on the Company's financial
     statements.

     In July 2002, the FASB has issued SFAS No. 146, "Accounting for Costs
     Associated with Exit or Disposal Activities." SFAS No. 146 requires
     companies to recognize costs associated with exit or disposal activities
     when they are incurred rather than at the date of a commitment to an exit
     or disposal plan. Examples of costs covered by the standard include lease
     termination costs and certain employee severance costs that are associated
     with a restructuring, discontinued operation, plant closing, or other exit
     or disposal activity. Previous accounting guidance, amended by SFAS No.
     146, was provided by EITF Issue No. 94-3, "Liability Recognition for
     Certain Employee Termination Benefits and Other Costs to Exit an Activity
     (including Certain Costs Incurred in a Restructuring)." SFAS No. 146 is to
     be applied prospectively to exit or disposal activities initiated after
     December 31, 2002.

Item 2.  Management's Discussion and Analysis of Results of Operations and
         Financial Condition

         This discussion should be read in connection with the information
contained in the Consolidated Financial Statements and Selected Notes to
Financial Statements.

Results of Operations

         Consolidated net sales were consistent for the quarter ended September
30, 2002 versus the quarter ended September 30, 2001. Consolidated net sales for
the year-to-date period ended September 30, 2002 decreased by $11.1 million or
5.4% versus the year-to-date period ended September 30, 2001 (an analysis of
sales by segment can be found in Note 5 of Selected Notes to Financial
Statements). Net sales for the activated carbon segment decreased by $0.9
million or 3.4% versus the quarter ended September 30, 2001 and $7.2 million or
8.8% versus the year-to-date period ended September 30, 2001. The decline for
both periods was primarily the result of lower sales volume in North America due
to the economic downturn that began in the latter part of 2001 and that has
continued through the end of the third quarter of 2002. Net sales for the
service segment increased by $0.8 million or 3.4% for the quarter ended
September 30, 2002 as compared to the quarter ended September 30, 2001. Service
segment sales for the year-to-date period ended September 30, 2002 were
consistent with the similar 2001 period. For both periods of comparison, slower
sales in North America were more than offset by increased sales in Europe and
the positive impact of foreign currency translation which was $0.7 million for
both the quarter and year-to-date periods. Revenues associated with the
engineered solutions segment decreased by $0.4 million or 3.8% for the quarter
ended September 30, 2002 versus the quarter ended September 30, 2001 and $6.3
million or 17.1% for the year-to-date period ended September 30, 2002 versus the
comparable 2001 period primarily due to lower revenues in 2002 associated with a
major project secured and substantially recorded in 2001. Sales to the consumer
segment for the quarter ended September 30, 2002 increased by $0.6 million or
11.8% compared to the quarter ended September 30, 2001 and $2.3 million or 14.1%
for the year-to-date period ended September 30, 2002 versus the similar 2001
period. The sales increase for the quarter is primarily due to increased sales
of new consumer products. The reason for the increase during the year-to-date
period of comparison was due to higher sales of charcoal, carbon cloth and new
consumer products. The total positive impact of foreign currency translation on
consolidated net sales for the quarter and year-to-date periods ended September
30, 2002 was $1.8 million and $1.5 million respectively.

Gross profit, before depreciation, as a percentage of net sales was 30.2% for
the quarter ended September 30, 2002 compared to 31.4% for the similar 2001
period, a 1.2 percentage point decline. For the year-to-date period, gross
profit, before depreciation, as a percentage of net sales was 30.8% in 2002
versus 33.4% in the 2001 period representing a 2.6 percentage point decline. The
decline for the quarter and year-to-date was primarily due to a combination of
costs associated with a major Engineered Solutions project and increased
charcoal production costs. Those cost increases were partially offset by lower
energy costs and lower cost of U.S. sourced carbon products shipped to the
Company's Belgian branch as a result of the strengthening of the Euro in 2002
versus the comparable 2001 periods in addition to higher production costs
realized in the third quarter of 2001 due to the labor strike at the Company's
Catlettsburg, Kentucky facility that was resolved in the first quarter of 2002.

The depreciation and amortization decreases of $0.2 million and $1.0 million
during the quarter and year-to-date periods ended September 30, 2002 versus the
quarter and year-to-date periods ended September 30, 2001 were related primarily
to the Company ceasing to amortize goodwill due to the implementation of
Statement of Financial Accounting Standards No. 142 "Goodwill and Other
Intangible Assets" as of January 1, 2002 partially offset by higher
depreciation.

Combined, selling, general and administrative expenses and research and
development expenses for the quarter ended September 30, 2002 were higher than
the comparable 2001 quarter by $0.9 million or 7.4%. The increase is the result
of a positive revision of the Company's pension expense estimate in the third
quarter of 2001 coupled with additional expense incurred due to the new carbon
facility in The People's Republic of China being operational for the entire
third quarter of 2002. Combined, selling, general and administrative expenses
and research and development expenses for the year-to-date period ended
September 30, 2002 were $0.8 million or 2.0% lower than the comparable 2001
period. The decrease represents the Company's commitment to aggressively control
spending during periods of lower sales demand.

                                       13



Other expense for the quarter and year-to-date periods ended September 30, 2002
increased by $0.2 million versus both comparable periods. The primary reason for
the increase in both periods presented is a small foreign exchange loss
recognized during the quarter and year-to-date periods in 2002 versus a small
foreign exchange gain recognized in the similar 2001 periods.

Interest expense, net of interest income, for the quarter and year-to-date
periods ended September 30, 2002 was below the quarter and year-to-date periods
ended September 30, 2001 by $0.1 million or 20.4% and $1.1 million or 42.3%,
respectively. The decrease in interest expense for both periods was primarily
the result of the combination of lower interest rates and a lower average level
of borrowings during the comparable periods.

Net income decreased by $1.0 million and $34.8 million for the quarter and
year-to-date periods ended September 30, 2002 versus the quarter and
year-to-date periods ended September 30, 2001 primarily for the reasons
discussed above and, for the year-to-date period, as a result of the $30.9
million after tax effect of the cumulative effect of change in accounting
principle related to the implementation of Statement of Financial Accounting
Standards No. 142, "Goodwill and Other Intangible Assets" (see note 8 to the
Selected Notes to Financial Statements.)

Financial Condition

     Working Capital and Liquidity

         Cash flows generated from operating activities were $18.4 million for
the nine month period ended September 30, 2002 versus cash generated from
operations of $16.6 million for the comparable 2001 period. The $1.8 million
increase represents a decrease in operating working capital (exclusive of debt)
in 2002 versus the comparable period in 2001 partially offset by lower earnings
and depreciation and amortization in 2002.

Common stock dividends paid during the quarter ended September 30, 2002
represented $.03 per common share versus dividends paid of $.05 per common share
for the quarter ended September 30, 2001.

Total debt at September 30, 2002 was $59.6 million, a decrease of $4.8 million
from December 31, 2001. The decline in debt was primarily the result of cash
generated by net operating cash flows greater than the Company's capital
expenditure and dividend requirements and those cash flows being used to repay
debt.

The Company expects that current cash from operating activities plus cash
balances and available external financing will be sufficient to meet its future
requirements.

The Company has a $113.4 million credit facility consisting of an $86.8 million
five-year revolving credit facility expiring in May 2004 and a $26.6 million
364-day revolving credit facility expiring in May 2004. The commitment under the
364-day revolving credit facility expired in May 2002 and was not renewed.
However, in order to preserve the full $113.4 million commitment of the credit
facility, the Company exercised its contractual option of borrowing the total
commitment of $26.6 million under the 364-day line before its May 2002
expiration. The $26.6 million of outstanding borrowings mature in May 2004 which
coincides with the expiration of the long-term portion of the credit facility.
Included in this facility is a letter of credit subfacility which may not exceed
$30.0 million. At September 30, 2002 there were $26.6 million of borrowings
under the 364-day revolving credit agreement. The weighted average interest rate
on the outstanding balance under this credit facility was 3.12% at September 30,
2002.

The Company is currently in compliance with all of the financial covenants in
the $113.4 million credit facility. One of those covenants is an interest
coverage ratio that requires the Company to maintain a trailing four quarters
earnings before interest and tax (EBIT) level greater than three times its
interest expense. Due to the Company's recent operating performance, the
potential exists that the Company could violate that interest coverage covenant
should future quarterly EBIT cause the trailing four quarters EBIT to fall below
its current level. Management intends to negotiate a waiver and an amendment to
its facility prior to any violation. Such waiver would require the consent of
the banks included in the credit facility.

                                       14



In January 2001, the Company entered into an interest rate swap that fixes $10.0
million of its outstanding variable rate U.S. credit facility at 5.48%. The
arrangement expires in January 2003.

Restructuring of Operations

         The Company currently has two separate restructuring plans requiring
continued cash outlays as of the period ended September 30, 2002. The latter of
the two initiatives was undertaken during the fourth quarter of 1999 while the
former commenced in the third quarter of 1998. The details of both restructuring
plans are outlined below.

During the fourth quarter of 1999, the Company adopted a strategy aimed at
lowering costs to serve the activated carbon markets, investing to grow its
service and solutions businesses and repositioning its proven technologies to
bring more value to consumers. In order to achieve these goals, the Company has
been reorganized as a globally integrated business with emphasis on providing
services and solutions to customer problems. The implementation began in
December 1999 and is essentially complete except for contractual cash outlays
for employee severance payments to be made in 2002 and other contractual cash
outlays, primarily lease obligations, through the second quarter of 2006.

In the third quarter of 1998, the Company initiated a worldwide plan to reduce
costs and realign the organization structure. The implementation began in
September 1998 and is essentially completed with the exception of some minor
contractual cash outlays that will continue through 2002.

                                       15



The restructuring reserve activity for the nine months ended September 30, 2002
was:

                                      ==========      ===========   ===========

     Management believes the reserve balances are adequate.

Capital Expenditures and Investments

         Capital expenditures for property, plant and equipment totaled $9.8
million for the year-to-date period ended September 30, 2002 compared to
expenditures of $8.4 million for the same period in 2001. The increase is
primarily the result of the Company's investment in the construction of a carbon
facility in the People's Republic of China. Capital expenditures for 2002 are
projected to be approximately $13.0 million.

Regulatory Matters

Each of the Company's domestic production facilities has permits and licenses
regulating air emissions and water discharges. All of the Company's domestic
production facilities are controlled under permits issued by local, state and
federal air pollution control entities. The Company is presently in compliance
with these permits. Continued compliance will require administrative control and
will be subject to any new or additional standards. In this regard, the Company
has agreed with the state of Kentucky that it will either begin installation of
additional control equipment on one of its three activated carbon lines at its
Catlettsburg, Kentucky facility by November 2003 or cease operations of this one
activated carbon line in May 2003. The Company has not started installation and
does not expect to have the additional control equipment installed by May 2003.
The activated carbon line has a net book value, including the coal handling
servicing equipment related to this line, of approximately $3,000,000.
Management has not concluded its plan of action for compliance related to this
activated carbon line, however, if it is ultimately determined that a shutdown
of the activated carbon line is warranted, operating results may be adversely
effected by increased depreciation or impairment charges on this line. The total
cost of the control equipment required for compliance, if installed, is
estimated at approximately $7.0 million. The Company is evaluating its
production capacity and related alternatives, including considering current
market demands. The Company believes that the cessation of production of the
activated carbon line, if temporary or other than temporary, will not have a
material impact upon the Company's ability to service the demands of its
customers.

New Accounting Pronouncements

       The FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations," which addresses financial accounting and reporting for obligations
associated with the retirement of tangible long-lived assets and the associated
asset retirement costs. Management has not yet evaluated the impact of the
adoption of SFAS No. 143 on the Company's financial statements. The Company
plans to adopt SFAS No. 143 on January 1, 2003 as required.

                                       16



In October 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets" which addresses financial accounting and
reporting for the impairment or disposal of long-lived assets. SFAS No. 144 is
effective for financial statements issued for fiscal years beginning after
December 15, 2001, and interim periods within those fiscal years. The Company
has adopted SFAS No. 144 as of January 1, 2002 as required with no resulting
impact on the Company's financial statements.

In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated
with Exit or Disposal Activities." SFAS No. 146 requires companies to recognize
costs associated with exit or disposal activities when they are incurred rather
than at the date of a commitment to an exit or disposal plan. Examples of costs
covered by the standard include lease termination costs and certain employee
severance costs that are associated with a restructuring, discontinued
operation, plant closing, or other exit or disposal activity. Previous
accounting guidance, amended by SFAS No. 146, was provided by EITF Issue No.
94-3, "Liability Recognition for Certain Employee Termination Benefits and Other
Costs to Exit an Activity (including Certain Costs Incurred in a
Restructuring)." SFAS No. 146 is to be applied prospectively to exit or disposal
activities initiated after December 31, 2002.

Item 4.  Controls and Procedures

The Company's principal executive officer and principal financial officer have
evaluated the effectiveness of the Company's "disclosure controls and
procedures," as such term is defined in Rule 13a-14(c) of the Securities
Exchange Act of 1934, as amended, (the "Exchange Act") within 90 days of the
filing date of this Quarterly Report on Form 10-Q. Based upon their evaluation,
the principal executive officer and principal financial officer concluded that
the Company's disclosure controls and procedures are effective to ensure that
information required to be disclosed by the Company in the reports filed or
submitted by it under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in the SEC's rules and forms, and
include controls and procedures designed to ensure that information required to
be disclosed by the Company in such reports is accumulated and communicated to
the Company's management, including its principal executive officer and
principal financial officer, as appropriate to allow timely decisions regarding
required disclosure.

There were no significant changes in the Company's internal controls or in other
factors that could significantly affect these controls subsequent to the date of
such evaluation.
