INTRODUCTION
The Company provides environmental technologies and specialty chemicals to
the coal-burning electric utility industry. Revenues are generated through
(1) time and materials contracts for the emerging mercury emission control
(MEC) market, several of which are co-funded by government and industry, (2)
the sale of specialty chemicals and services for flue gas conditioning (FGC),
and (3) the sale of combustion aid (CA) chemicals and services, primarily
ADA-249 through a joint venture with Arch Coal.

Mercury has been identified as a toxic substance and the EPA is under court
order to issue regulations for its control, which are expected in March 2005.
The growth of the MEC market for the electric utility industry will most
likely be dependent on federal and/or state regulations, which are in various
stages of enactment.  As many as 1,100 existing coal-fired boilers may be
affected by such regulations, if and when they are enacted.  Permitting of
new coal-fired plants generally requires them to meet more stringent
requirements that likely include MEC. For the near-term, our revenues from
this emerging market will be dependent on (i) DOE- and industry-funded
contracts, (ii) mercury testing services and (iii) equipment sales and
commissions on sorbents sold to new plants and existing plants affected by
enacted regulations.  Although we expect this market to show steady growth
over the next several years, significant revenue growth is anticipated when
federal regulations impact the large market of existing boilers.

The market for our FGC chemicals and services is relatively flat and is
expected to only show modest growth, if any, in the near-term.  Margins on
these products are typically higher than what we recognize for our present
MEC sales and represent an important contribution to the overall
profitability of the Company.  In spite of several successful demonstrations,
market acceptance for our CA products has not grown as previously expected.
Commencement of continuing sales to a significant customer in 2004 is
important, and is expected, if such occurs, to help promote additional sales.

The Company recently announced that it has signed a commercial contract for
$455,000 to supply activated carbon injection equipment for mercury control
to a utility client. The system is expected be used as part of a test plan
for the coal-fired plant to comply with State requirements to reduce mercury
emissions and is expected to be delivered and installed during the third
quarter of 2004.

The Company also recently announced it signed a commercial contract to supply
and install a FGC system to improve capture of flyash particles at a
Midwestern coal-fired power plant. The plant is making provisions to switch
to coal from the Wyoming Powder River Basin (PRB). The Company's proprietary
FGC technology is expected to enhance performance of the plant's high
temperature electrostatic precipitator (ESP), which captures the flyash
particles.  The contract calls for the purchase and installation of
the equipment for approximately $300,000. The Company expects the equipment
to be installed and operational in December 2004 and at that time, it is
expected to begin injecting the Company's proprietary chemical. Based upon
historical average usage of the chemical at existing customers' plants, it is
anticipated that future chemical purchases will provide additional revenues
of $500,000 - $700,000 per year.

Liquidity and Capital Resources
The Company had a positive working capital of $1.1 million at 6/30/04. The
amount represents approximately no change for the quarter. Management
believes that existing and expected improving working capital, through
continued and improved cash flow from ongoing operations, will be sufficient
to meet the anticipated needs of the Company throughout 2004. However, there
can be no assurances that the positive cash flow that has been achieved will
continue. The Company also has a $250,000 line-of-credit arrangement, which
was renewed in May with a bank to help with its working capital needs. No
amounts were outstanding under the line as of 6/30/04.

The Company's principal source of liquidity is its existing working capital
and operating cash flows as supplemented by its line-of-credit noted above.
The continuation of positive cash flow is somewhat dependent upon the
continuation of chemical sales and operations of the flue gas conditioning
(FGC) units currently in-place in Wisconsin, Louisiana and Iowa, each of
which provide an average monthly cash flow of approximately $20,000.
Unsatisfactory results, which could be caused by a combination or single
factor such as changes in coal, mechanical difficulties (whether in the FGC
unit or otherwise), and/or overall cost/benefit analysis, at any of those
units may decrease or end the sale of chemicals for such units. The Company
is also performing services under three DOE and industry co-funded contracts,
which overall are expected to produce an estimated $5.1 million in revenues
in 2004. Of that amount approximately 15% represents cost share amounts from
industry partners, and 50% represents reimbursement from DOE for costs that
pass through the Company. Currently funding has been approved by the DOE for
approximately $4.1 million of its share of those contracts. If further
funding were not approved, the Company would decrease or cease activities on
those contracts and we would expect to maintain a positive cash flow but at a
somewhat reduced level.

Debt service obligations in 2004 total approximately $145,000, although the
Company made an additional unscheduled payment of $300,000 on its term debt
during the first quarter of 2004 in an effort to reduce interest expense.
Planned capital expenditures for ADA-ES to sustain and improve ongoing
operations for 2004 are estimated at $400,000. The Company expects to fund
these requirements out of existing working capital and cash flow from
operations.

The Company assumed a defined contribution and 401(k) plan covering all
eligible employees from Earth Sciences Inc. as of January 1, 2003.  The
Company matches up to 5% of salary amounts deferred by employees in the Plan.
During the first half of 2004, the Company recognized $34,000 of matching
expense; this expense is expected to amount to approximately $86,000 in 2004.
In the past the Company has also made discretionary contributions to the Plan
amounting to approximately 10% of salaries, which amounts were paid in stock.
At December 31, 2003, the Company had authorized a discretionary contribution
of $147,000, which amount was paid in the first quarter of 2004 through the
issuance of stock.  In 2004 such discretionary amounts may be paid as bonuses
and, based on budget figures, may total approximately $206,000.  As of
6/30/04 approximately $7,000 has been accrued for these potential payments as
a result of the net income recognized in the first half of 2004.

The Company has recorded net deferred tax assets of $93,000 as of 12/31/03.
Based on existing R&D contracts supported by the DOE and industry, the
Company has determined that it is more probable than not that those deferred
tax assets will be realized in the future.

Cash flow provided from operations totaled $677,000 for the first six months
of 2004 compared to a use of ($4,000) for same period in 2003. Cash flow from
operations in 2004 was higher than 2003 as the result of significant
increases in accounts payable and deferred revenues in the first half of
2004, which change improved the Company's cash flow at the end of the current
period. Cash flow provided from operations in 2004 resulted primarily from
the operating income plus non-cash charges for depreciation, amortization and
expenses paid with stock plus and minus other components of working
capital. Cash flow from net investing activities for 2004 includes a use for
capital expenditures of $(325,000). Cash flow from financing activities in
2004 consisted of payments on notes payable of $(370,000), and proceeds from
the exercise of stock options of $341,000. Cash flow used in operations in
2003 also resulted primarily from 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 2003 includes a use for
capital expenditures of $(249,000). Cash flow from financing activities in
2003 consisted of payments on capital leases of ($3,000), proceeds from a
note payable of $100,000 and advances to its then parent company, ESI,
of $(106,000).

Results of Operations
Revenues totaled $1,774,000 in the second quarter of 2004 versus $1,605,000
for the same period in 2003. Revenues for the second quarter of 2004
increased $264,000 due to increased sales in MEC and CA activities and
decreased $95,000 from FGC activities. The decline in FGC revenues is
primarily the result of chemical sales in the second quarter 2003 for one
temporary user in 2003 that were not repeated in the second quarter of 2004
and revenues from a DOE supported program that was completed in 2003. The
Company sold FGC chemicals and services to three utilities during the second
half of 2003, all of which were continuing customers in the first half of
2004.  We expect FGC revenues in 2004 to show only modest growth, assuming
the contract for a new installation noted above is completed in 2004. CA
revenues for the half quarter of 2003 include installation of a feed system
at one of our continuing customers that was not repeated in the first half of
2004.  CA revenues for the first half of 2004, although minor, represent
chemical sales to three continuing customers.  In order for CA revenues to
grow appreciably, we will need to add additional customers.  MEC revenues are
primarily a function of government and industry supported field
demonstrations of our mercury control technology and other consulting in
mercury emission measurement.  The MEC revenues for the second quarter of
2004 represent an increase of 25% from the same period in 2003, but
are somewhat below anticipated levels due solely to delays in
planned activities that are expected to be performed at a later date. The
Company's government contracts are subject to audit by the federal
government, which could result in adjustment(s) to previously recognized
revenue. The Company believes, however, it has complied with all the
requirements of the contracts and future adjustments, if any, will not be
material.   Based on contracts in hand, total revenues for 2004 are
anticipated to grow by approximately 30% from the 2003 level.

Cost of services increased by $207,000 in the second quarter of 2004, and
increased $493,000 in the first half of 2004 as compared to the same periods
in 2003 both as a result of the increased revenue generating activities. ADA-
ES experienced positive gross margins in the second quarters of 2004 and 2003
of 45% and 52%, respectively.  As noted above, management expects the amount
of time and materials work to represent an increasing source of revenues
wherein the anticipated gross margins are less than for our specialty
chemical sales.  Gross margins for 2004 are expected to decline from the
levels achieved in 2003, both as a result of an increasing proportion of time
and materials work and the Company's increasing its share of costs in the
field demonstration projects in which it has elected to participate.

Research and development increased in the second quarter of 2004 by $87,000
to $263,000 as compared to $176,000 in 2003. For the first half of 2004, such
expenses increased $153,000 to $479,000.  The Company incurs R&D expenses
not only on direct activities it conducts but also by sharing a portion of
the costs in the government and industry programs in which it participates.
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 grow at about 10% per year for the next several
years.

General and administrative expenses decreased by $63,000 to $440,000 in the
second quarter of 2004, and decreased $84,000 to $896,000 for the first half
of 2004. However, the amount shown for 2004 excludes a profit sharing expense
of approximately $67,000 that was included in the $980,000 shown for the same
period of 2003. The otherwise increase in the first quarter of 2004 results
primarily from increases in staff and our office space as the Company
prepares for the anticipated growth in the mercury control market, and other
general increases in costs, such as insurance.

The Company's interest expense totaled approximately $10,000 and $24,000 for
the second quarter and first half of 2004 and $1,000 each for the same
periods in 2003. As a result of the debenture to Arch Coal and the term debt
noted above we expect interest expense in 2004 to total around $42,000.

Critical Accounting Policies and Estimates
Significant estimates are used in preparation of the financial statements and
include the Company's allowance for doubtful accounts, which is based on
historical experience. However, a significant amount of the Company's
accounts receivable ($203,000 and $249,000 at June 30, 2004 and 2003,
respectively) is from the federal government. Amounts invoiced for government
contracts are subject to change based on the results of future audits by the
federal government. The Company has not experienced significant adjustments
in the past, nor do we expect that a significant adjustment will be made in
the future. The Company uses its judgment to support the current fair value
of goodwill and other intangible assets of $2.2 million on the consolidated
balance sheet. Although the Company has had an independent valuation
prepared, which supports its recorded value and, management believes the fair
value of other recorded intangibles are not impaired, market demand for the
Company's product and services could change in the future requiring a write-
down in recorded values. As with all estimates, the amounts described above
are subject to change as additional information becomes available.

Item 3.  CONTROLS AND PROCEDURES

Disclosure Controls and Procedures
The Company maintains disclosure controls and procedures designed to ensure
that it is able to collect the information it is required to disclose in the
reports it files with the Securities and Exchange Commission (SEC), and to
process, summarize and disclose this information within the time periods
specified in the rules of the SEC. Based on their evaluation of the Company's
disclosure controls and procedures which took place as of June 30, 2004, the
end of the period covered by this report, the Chief Executive and Financial
Officers believe that these controls and procedures are effective to ensure
that the Company is able to collect, process and disclose the information it
is required to disclose in the reports it files with the SEC within the
required time periods.

The Company also maintains a system of internal controls designed to provide
reasonable assurance that: transactions are executed in accordance with
management's general or specific authorization; transactions are recorded as
necessary (1) to permit preparation of financial statements in conformity
with generally accepted accounting principles, and (2) to maintain
accountability for assets; access to assets is permitted only in accordance
with management's general or specific authorization; and the recorded
accountability for assets is compared with the existing assets at reasonable
intervals and appropriate action is taken with respect to any differences.

During the company's last fiscal quarter, there have been no significant
changes in such controls or in other factors that have materially affected,
or is reasonably likely to materially affect, those controls.
