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 six months of 2002 are not necessarily indicative of the results that may
be expected for the year ending December 31, 2002.

5.   Segment Information:

     The Company has four reportable segments: Activated Carbon, Service,
     Engineered Solutions and Consumer. These reportable segments are comprised
     of 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
     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 resulting from changes in the fair value
     of derivative instruments. As of June 30, 2002, the Company held four
     derivative instruments, three foreign exchange contracts and an interest
     rate swap agreement. None of the four derivatives received hedge accounting
     treatment under SFAS No. 133 and were marked to market through the
     Company's earnings for the six months ended June 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") 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

                                       8



     litigation against the Town of Ontario, NY and Robert Wykle, et al. in the
     United 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. Neither the Company nor its counsel can predict with any
     certainty the outcome of the two 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.

     The following is the categorization of the Company's intangible assets as

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 decreased by $7.4 million or 9.9% and $11.2
million or 7.9% for the quarter and year-to-date periods ended June 30, 2002
respectively, versus the quarter and year-to-date periods ended June 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
$4.4 million or 16.0% versus the quarter ended June 30, 2001 and $6.3 million or
11.1% versus the year-to-date period ended June 30, 2001. The decline was
primarily the result of lower sales volume in all geographic markets. Net sales
for the service segment for the quarter and year-to-date periods ended June 30,
2002 were consistent with the similar 2001 periods. Revenues associated with the
engineered solutions segment decreased by $3.7 million or 25.9% for the quarter
ended June 30, 2002 versus the quarter ended June 30, 2001 and $5.9 million or
22.9% for the year-to-date period ended June 30, 2002 versus the comparable 2001
period primarily due to lower revenues in 2002 associated with a major project
secured in 2001 that is now nearing completion. Sales to the consumer segment
for the quarter ended June 30, 2002 increased by $1.3 million or 17.7% compared
to the quarter ended June 30, 2001 and $1.8 million or 15.0% for the
year-to-date period ended June 30, 2002 versus the similar 2001 period. The
reasons for the increase during both periods of comparison were due to higher
sales of charcoal, carbon cloth and the Company's new consumer products. The
total positive impact of foreign currency translation on consolidated net sales
for the quarter ended June 30, 2002 was $1.0 million. The total adverse impact
of foreign currency translation on consolidated net sales for the year-to-date
period ended June 30, 2002 was $0.3 million.

Gross profit, before depreciation, as a percentage of net sales was 31.3% for
the quarter ended June 30, 2002 compared to 33.5% for the similar 2001 period, a
2.2 percentage point decline. For the year-to-date period, gross profit, before
depreciation, as a percentage of net sales was 31.2% in 2002 versus 34.3% in the
2001 period representing a 3.1 percentage point decline. The decline for the
quarter was primarily due to a combination of costs associated with the start-up
of a major Engineered Solutions project partially offset by lower costs of raw
materials in 2002 versus the comparable 2001 period. In addition to the
aforementioned reasons, the year-to-date decline was also affected by production
inefficiencies resulting in higher product costs and competitive pricing in
certain of the Company's Activated Carbon and Service segments.

The depreciation and amortization decreases of $0.3 million and $0.7 million
during the quarter and year-to-date periods ended June 30, 2002 versus the
quarter and year-to-date periods ended June 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.

Combined, selling, general and administrative expenses and research and
development expenses for the quarter and year-to-date periods ended June 30,
2002 were below the comparable 2001 quarter and year-to-date periods by $0.8
million or 6.0% and $1.7 million or 6.3%, respectively. The decrease during both
periods represents the Company's commitment to manage controllable costs such as
travel and professional services during periods of lower sales demand.

Other expense for the quarter ended June 30, 2002 increased by $0.6 million, a
greater than two-fold increase as compared to June 30, 2001 due to a June 2001
gain resulting from marking derivative instruments to market and a change in
estimate of certain non-income related taxes in 2001. Year-to-date, other
expense is comparable for the 2002 and 2001 periods.

Interest expense, net of interest income, for the quarter and year-to-date
periods ended June 30, 2002 was below the quarter and year-to-date periods ended
June 30, 2001 by $0.4 million or 44.9% and $1.0 million or 49%, 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.

                                       12



Net income decreased by $1.9 million and $33.8 million for the quarter and
year-to-date periods ended June 30, 2002 versus the quarter and year-to-date
periods ended June 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 Noted to Financial
Statements.)

Financial Condition

     Working Capital and Liquidity

         Cash flows generated from operating activities were $11.0 million for
the six month period ended June 30, 2002 versus cash generated from operations
of $9.6 million for the comparable 2001 period. The $1.4 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 June 30, 2002 represented
$.03 per common share versus dividends paid of $.05 per common share for the
quarter ended June 30, 2001.

Total debt at June 30, 2002 was $65.7 million, an increase of $1.3 million from
December 31, 2001. The additional borrowings were used primarily to fund capital
expenditures.

The Company expects that current cash from operating activities plus cash
balances and available external financing will be sufficient to meet its
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 June 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 2.75% at June 30, 2002.

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 June 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.

                                       13



The restructuring reserve activity for the six months ended June 30, 2002 was:

     Management believes the reserve balances are adequate.

Capital Expenditures and Investments

         Capital expenditures for property, plant and equipment totaled $7.8
million for the year-to-date period ended June 30, 2002 compared to expenditures
of $6.0 million for the same period in 2001. The increase is primarily the
result of the Company's continuing investment in the construction of a carbon
facility in the People's Republic of China. Capital expenditures for 2002 are
projected to be approximately $20.0 million which includes the establishment of
a new Center of Excellence in the Gulf Coast region of the United States in
addition to the construction of the aforementioned carbon facility.

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

                                       14



Recognition for Certain Employee Termination Benefits and Other Costs to Exit an

to be applied prospectively to exit or disposal activities initiated after
December 31, 2002.
