                                   June 30, 2002

(1)  General
The accompanying consolidated financial statements were prepared in
accordance with generally accepted accounting principles and reflect all
adjustments which are, in the opinion of management, necessary for fair
representation of the financial results for the interim periods shown.  Such
statements should be considered in conjunction with Registrant's 2001 Form
10-KSB.

(2) Business Segment Information
Corporate headquarter activities are part of the ESI operating segment.  The
segment assets of the ESI and ADA segments are located in the US while the
assets of ESEC are located in Canada.  All significant customers are US
companies.

(3) Impact from Application of SFAS 142
In the first six months of 2002 the adoption of SFAS 142 resulted in a
reduction of amortization expense of approximately $194,000 as compared to the
same period in 2001. Had this statement been adopted at the beginning of 2001,
the Company's loss for the first six months of 2001 would have been reduced to
($177,000) and the loss per share for the six month period ended 6/30/01 would
have been less than ($.01).

Item 2.	MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION
This Quarterly Report may contain forward-looking statements within the meaning
of Section 27A of the Securities Act of 1933. Actual events or results could
differ materially from those discussed in the forward-looking statements as a
result of various factors including those set forth below or under the heading
"Description of Business" contained in the Company's Annual Report on Form 10KSB
for the year ended December 31, 2001.

Liquidity and Capital Resources
Registrant had a working capital of $163,000 at 6/30/02. Working capital has
increased during the first six months of the year from $111,000 at 12/31/01.
Management expects to further increase working capital through continued and
improved cash flow at ADA-ES.  However, there can be no assurances that the
positive cash flow that has been achieved at ADA-ES will continue.

                                   4
<PAGE>
For ADA-ES, the continuation of positive cash flow is dependent upon the
successful ongoing operation of the units currently in-place in Wisconsin,
Louisiana, and Iowa. Unsatisfactory operations at any of the units operating
could frustrate such continuation. ADA-ES is also performing services under
two DOE contracts, which are expected to produce an estimated $2.0 million in
revenues in 2002.  Currently funding has been approved for approximately $1.7
million of that amount.

Planned capital expenditures for ADA-ES to sustain and improve ongoing
operations for 2002 are estimated at $150,000. Registrant expects to fund these
requirements out of existing working capital.

In an effort to reduce cash flow deficits from the Calgary facility, as of
August 31, 1999, management suspended production. Although limited discussions
continue with parties interested in purified phosphate production, it is
likely that surplus equipment may be sold and long-term subleasing arrangements
will be sought.  Discussions to date have not yet yielded substantial results.

Cash flow provided (used) in operations totaled ($474,000) for the first quarter
of 2002 compared to $32,000 for the same period in 2001. The use in 2002
resulted primarily from advance payments received prior to year-end 12/31/01,
not received during the first six months, net of the operating income plus non-
cash charges for depreciation and amortization, and changes in other operating
assets and liabilities. Cash flow from investing activities for 2002 includes a
use for capital expenditures of $30,000. Cash flow from financing activities in
the first quarter of 2002 consisted of payments on notes payable of $101,000 and
proceeds from a recently approved line of credit of $100,000. Cash flow from
investing activities for 2001 includes a use for capital expenditures of
$78,000. Cash flow from financing activities in the first six months of 2001
consisted of payments on notes payable of $74,000, proceeds from a note payable
of $33,000 and proceeds from the issuance of common stock related to the
exercise of certain options of $16,000.

Results of Operations
Revenues from sales totaled $2,455,000 in 2002 versus $2,526,000 in 2001. In
2002 and 2001 all significant revenues were generated by ADA-ES. Revenues for
the period decreased due the timing of work on government contracts during the
period as compared to the same period last year. ADA-ES' government contracts
are subject to audit by the federal government, which could result in
adjustment(s) to previously recognized revenue.  The Registrant believes,
however, it has complied with all the requirements of the contracts and future
adjustments, if any, will not be material. Revenues from government contracts
for the first six months of 2001 and 2002 include amounts from the adjustment
of certain estimated overhead rates from the prior year.  These amounts have
increased revenues by $113,000 and $222,000 in 2001 and 2002, respectively.

Operating expenses also decreased during the first six months of 2002 as
compared to the same period in 2001 as a result of the decreased government
contract work. The profit margins recognized on such contracts are generally
less than in ADA-ES' commercial activities. In spite of the low gross margins
produced by government contracts, the Company plans to continue to use
government programs to fund its technology development and commercialization
efforts.  The Company has submitted several multi-million dollar proposals to
the government to continue to fund products for sale into the rapidly
developing mercury control market.  DOE has estimated that this market will
become a $2-5 billion per year industry by 2007 based upon expected new
environmental regulations.

ADA-ES has recognized positive gross margins in since 2000, but these were some-
what less than anticipated from routine operations and have resulted from ADA-ES
activities to establish further market acceptance and its market share for its
flue gas conditioning and ADA-249 products. The Company's continued and future
success will be dependent upon generating improved gross margins, which in turn
are dependent upon increased sales and market penetration. Development expenses
related to the introduction of ADA-249 increased expenses by a net of
approximately $66,000  in the first six months of 2001 as compared to the same
period in 2002.

Consolidated research and development for the period increased slightly in 2002
to $53,000 as compared to $31,000 for the same period in 2001. Future
consolidated research and development expenses, except for those anticipated to
be funded by the DOE contracts and others that may be awarded, are expected to
be approximately $100,000 per year for the next several years.

General and administrative expenses increased slightly to $983,000 in 2002
primarily as a result of the lower level of work on government contracts during
the period which work tends to absorb general expenses.

Registrant's interest expense totaled approximately $92,000 for the first six
months of 2002 and $108,000 for same period in 2001. In April 2002 ADA-ES
entered into a $350,000 line of credit arrangement with Wells Fargo Bank to
replace its accounts receivable factoring agreement.  As of 6/30/02 ADA-ES had
borrowed approximately $100,000 under the line to offset higher receivable
balances that were otherwise funded by the factoring arrangement. Reduced
interest charges and fees are anticipated as a result of the new credit line.

In the fourth quarter of 2001, Registrant recorded a non-cash write down
totaling $2,088,000 in the carrying value of the Calgary facility.  This
write-down is in addition to a $2,873,000 non-cash write down recorded in 2000.
The further write down was made in recognition of (i) the changed business
climate after the events of September 11, 2001 which has made unlikely any
near-term purified phosphate production at the facility and (ii) the fact that
the remaining capitalized costs were not expected to be recovered out of the
now anticipated future operations.  The write down reduced the net asset
carrying value to a level that management believes will be recoverable from
the sale of surplus equipment and future subleasing of the building and site.
Such write-down has reduced the depreciation expense recorded by Registrant
in the amount of $215,000 for the six month period ended June 30, 2002 as
compared to the same period in 2001.

Currently the Company is leasing portions of its facility in Calgary, and a
substantial portion of the equipment not being used in leasing activities is
held for sale. The Company is continuing to investigate alternative uses for
other portions of the facility that are not held for sale or currently leased.

Although the Company continues to conduct business in Canada, as described
above, should the Company change its strategy and elect to discontinue its
operations in Canada, it will be required to recognize a $1,837,000 non-cash
expense in the statement of operations for the Cumulative Translation Adjustment
that is currently recorded in stockholders' equity as an offset. If the Company
discontinues its business in Canada and this adjustment is made, it will have no
effect on the Company's net equity.

The Calgary facility is located on a site leased from the adjacent landowner who
originally supplied feedstock to the facility in the 1980's. The lease has an
indefinite term, but upon ESEC's permanent termination of operations, ESEC has a
period of 24 months to remove all equipment, improvement and structures erected
on the site after which time such assets become the sole property of the
landlord. ESEC also has the obligation to return the site and any surrendered
assets to the landlord in a safe condition that complies with the requirements
of all statues, regulations and ordinances.  Although ESEC has no current intent
to terminate the lease and believes the site is currently in compliance with all
regulations, ESEC has accrued and recorded as a liability approximately $600,000
as an estimate of the ultimate costs it would expect to incur to return the
facility to the landlord under the terms of the lease.  The amount recorded is
an estimate that includes significant assumptions, and it is reasonably possible
that these assumptions could change in the future, and that such a change could
be material. The landlord commissioned a Phase 1 environmental study of the
leased site.  Although this Phase 1 study did not include any costs estimates,
the landlord has estimated the cost substantially higher than ESEC's estimated
costs.  The difference in estimates primarily relates to ESEC basing its
estimate on revised quantities of the waste on site, assumptions regarding
future us of the building (including the future cost to demolish the building),
and supervision costs. Any significant change to ESEC's estimates could result
in further expenses being recorded at that time.

As of January 1, 2002 the Company adopted the Financial Accounting Standards
Board Statements of Financial Accounting Standards No. 141 "Business
Combinations" ("SFAS 141") and No. 142 "Goodwill and Other Intangible Assets"
("SFAS 142").  SFAS 141 establishes specific criteria for the recognition of
intangible and goodwill in business combinations.  SFAS 142 changes the
accounting for goodwill and other intangible assets after an acquisition.
The Company will routinely perform a detail valuation analysis in connection
with the application of these statements, which may result in future charges.
However, it does not believe that the application of these statements will
have a material effect on its future financial position or cash flows. In the
first six months of 2002 the adoption of these statements resulted in a
reduction of amortization expense of approximately $194,000 as compared to
the same period in 2001. Had these statements been adopted at the beginning
of 2001, the Company's loss for the first six months of 2001 would have been
reduced to ($177,000) and the loss per share would have been less than ($.01).
