                          INDEPENDENT AUDITOR'S REPORT

To  the  Trustees
American  Ecology  Corporation  401(k)  Savings  and  Retirement  Plan and Trust

We  have audited the accompanying statement of net assets available for benefits
of  American Ecology Corporation 401(k) Savings and Retirement Plan and Trust as
of December 31, 2002 and 2001 and the related statement of changes in net assets
available  for  benefits  for the year ended December 31, 2002.  These financial
statements  are the responsibility of the Plan's management.  Our responsibility
is  to  express  an  opinion  on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in  the  United  States  of  America.  Those  standards require that we plan and
perform  the  audit  to  obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test  basis,  evidence  supporting  the amounts and disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made  by  management,  as well as evaluating the overall
financial  statement  presentation.  We  believe  that  our  audits  provide  a
reasonable  basis  for  our  opinion.

In  our  opinion,  the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of American Ecology
Corporation 401(k) Savings and Retirement Plan and Trust as of December 31, 2002
and  2001  and the changes in its net assets available for benefits for the year
ended  December  31,  2002  in  conformity  with accounting principles generally
accepted  in  the  United  States  of  America.

Our  audit was made for the purpose of forming an opinion on the basic financial
statements  taken  as  a  whole.  The supplemental schedule on pages 9 and 10 is
presented  for  the purpose of additional analysis and is not a required part of
the  basic financial statements but is supplementary information required by the
Department  of  Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974.  This supplemental schedule
is  the  responsibility of the Plan's management.  The supplemental schedule has
been  subjected  to  the  auditing  procedures applied in the audit of the basic
financial  statements for the year ending December 31, 2002 and, in our opinion,
is  fairly  stated  in  all material respects in relation to the basic financial
statements  taken  as  a  whole.

NOTE 1 - DESCRIPTION OF PLAN

     The  following brief description of the American Ecology Corporation 401(k)
     Savings  and  Retirement  Plan and Trust (the Plan) is provided for general
     information  purposes  only. Participants should refer to the Plan document
     for  complete  information  regarding  the  Plan's  definitions,  benefits,
     eligibility,  and  other  matters.

     GENERAL - The Plan is a defined contribution plan covering all employees of
     American  Ecology  Corporation  and its subsidiaries (the Company) who have
     one  year  of  service  and are age eighteen or older. A year of service is
     defined  as a 12-consecutive month period in which an employee completes at
     least  1,000 hours of service. The Plan is subject to the provisions of the
     Employee  Retirement  Income  Security  Act  of  1974  (ERISA).

     Effective January 1, 2003, all employees of the Company who have 90 days of
     service  and  are  age eighteen or older are eligible to participate in the
     Plan.

     CONTRIBUTIONS  -  Each  year,  participants  may defer up to 100 percent of
     their  compensation  as  defined  by the Plan, up to the maximum deferrable
     amount  allowed  by the Internal Revenue Service. Participants may elect to
     deposit  their  contributions  in  any of the investment options available.
     Participants  may  also  contribute amounts representing distributions from
     other  qualified  plans.  Participants  direct  the  investment  of  their
     contributions  into  various  investment  options  offered by the Plan. The
     Company  contributes  a  discretionary  matching  contribution,  which  is
     determined  by the Employer. For 2002 and 2001, the Company established the
     discretionary  matching  contribution  for  all  participants  equal  to 55
     percent  of the amount of compensation deferred by each participant for the
     calendar  year  not  exceeding 6 percent of compensation. In 2002, the Plan
     contributed $294,481 of back pay to members of the Oil, Chemical and Atomic
     Workers  Union  as  part  of  a  stipulation enforced by the National Labor
     Relations  Board.

     PARTICIPANT  ACCOUNTS  -  Each  participant's  account is credited with the
     participant's elective deferral, the Company's matching contribution and an
     allocation  of  Plan  earnings  and  charged  with  an  allocation  of
     administrative  expenses.  Allocations are based on participant earnings or
     account  balances  as  defined.  Forfeitures  of  terminated  participant's
     nonvested benefits are applied to reduce the Company's future contributions
     to  the  Plan.


                                                                               4

NOTE 1 - DESCRIPTION OF PLAN  (Continued)

     VESTING  -  The  vesting  schedule  is  as  follows  on  Company  matching
     contributions  and  actual  earnings  thereon:



                                 
                                     Percentage of
          Service                   Vested Interest
          -------                   ---------------
           1 year                               20%
           2 years                              60%
           3 years                             100%


     The  Plan provides for participants to be 100% vested upon death, permanent
     disability  or  the  attainment  of  age  65.

     PARTICIPANT  LOAN  -  Participants  may  borrow  from their fund accounts a
     minimum  of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of
     their  account balance. The term of the loan will not exceed 5 years except
     in the case of a loan for the purpose of acquiring a primary residence. The
     term  of  the  loan will be determined by the Administrator at the time the
     loan  is  made.  The  loans are secured by the balance in the participant's
     account  and  bear  interest  at  a rate commensurate with local prevailing
     rates  as  determined  by the Plan administrator. Interest rates range from
     5.0%  to  9.5%.  Principal  and  interest is paid ratably through bi-weekly
     payroll  deductions.

     PAYMENT  OF BENEFITS - Upon normal retirement or death, vested benefits due
     to participants and their beneficiaries may be paid in the form of either a
     lump-sum  distribution  or  fixed  period  annuities.

     FORFEITED  ACCOUNTS  -  At  December 31, 2002, forfeited nonvested accounts
     totaled  $8,610.  This  amount  will  be  used  to  reduce  future employer
     contributions.

     RISK - Investment securities are exposed to various risks, such as interest
     rate,  market,  and credit risk. It is reasonably possible, given the level
     of risk associated with investment securities that changes in the near term
     could  materially  affect  the investment amounts reported in the financial
     statements.


                                                                               5

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES

     USE  OF  ESTIMATES  - The preparation of financial statements in conformity
     with  generally  accepted  accounting  principles  requires  the  plan
     administrator  to  make  estimates  and  assumptions  that  affect  certain
     reported  amounts  and  disclosures. Accordingly, actual results may differ
     from  those  estimates.

     INVESTMENT  VALUATION  AND  INCOME RECOGNITION - The Plan's investments are
     stated  at  fair  value  except  for  its  benefit-responsive  investment
     contracts,  which  are  valued  at  contract  value (see Note 3). All other
     investments  are  carried  at  their  fair  value measured by quoted market
     prices.

     Purchases  and  sales  of  securities  are  recorded on a trade-date basis.
     Dividends  are  recorded  on  the  ex-dividend  date.  Investment income is
     recorded  as  earned.

     PAYMENT  OF  BENEFITS  -  Benefits  are  recorded  when  paid.


NOTE 3 - GUARANTEED INTEREST ACCOUNTS

     The  fair  value of the guaranteed interest accounts held by the Plan is as
     follows  at  December  31:

NOTE 4 - INVESTMENTS

The  following  presents  investments  that  represent  5 percent or more of the
Plan's  net  assets:

Manulife Lifestyle Conservative          580,968           -


NOTE 5 - PARTY-IN-INTEREST TRANSACTIONS

     Certain  Plan  investments  include pooled separate accounts and guaranteed
     investment contracts that are managed by Manulife Financial and, therefore,
     these  transactions  qualify  as  party-in-interest  transactions.

     The  Plan  invests  in  company  stock.

NOTE 6 - PLAN TERMINATION

     Although  it  has  not  expressed  any intent to do so, the Company has the
     right  under  the  Plan to discontinue its contributions at any time and to
     terminate the Plan subject to the provisions of ERISA. In the event of Plan
     termination, participants would become 100 percent vested in their employer
     contributions.


NOTE 7 - INCOME TAX STATUS

     The Plan obtained its latest determination letter on April 9, 2001 in which
     the  Internal  Revenue  Service  stated  that  the  original  Plan  and all
     amendments  through  December  11,  2000,  were  in  compliance  with  the
     applicable  requirements  of  the Internal Revenue Code (IRC). The Plan has
     been  amended  since  receiving the determination letter. However, the Plan
     administrator  believes the Plan as currently designed is being operated in
     compliance  with  the  applicable  requirements  of  the  IRC.


                                                                               8
