          AMERICAN ECOLOGY ACQUIRES ENVIROSAFE SERVICES OF IDAHO, INC.

        PROFITABLE IDAHO AND ILLINOIS HAZARDOUS WASTE OPERATIONS INCLUDED

      BOISE, Idaho - Jack Lemley, Chairman, President, and CEO of Boise, Idaho
based American Ecology Corporation [NASDAQ: ECOL], today announced the
acquisition of Envirosafe Services of Idaho, Inc. in a stock purchase from
EnviroSource Corporation of Horsham, Pennsylvania.

      "This acquisition is a major step for our Company and is right in line
with our targeted growth strategy," Lemley stated, adding "These well
established, profitable waste treatment and disposal assets are a superb fit
with American Ecology's existing core businesses."

      Operating as a wholly-owned subsidiary of American Ecology, the new
company is expected to provide annual revenue of approximately $12 million and a
significant, accretive contribution to earnings.

      Envirosafe Services of Idaho's principal operation is a hazardous waste
treatment and disposal facility located in the southwestern Idaho desert. "Our
new Idaho landfill operation extends American Ecology's existing, competitive
position for hazardous waste in the western United States while significantly
increasing the range of state-of-the art services we offer our customers,"
Lemley explained.

      Chief among these new services is a patented, U.S. EPA-approved steel mill
waste treatment technology to stabilize and "delist" certain hazardous wastes
generated by steel mills, allowing economical disposal as non-hazardous
industrial waste.

      In addition to the Idaho landfill operations, Envirosafe Services of Idaho
is also licensed to use the patented delisting technology at a steel mill in
Sterling, Illinois. "Acquiring this onsite contract and waste processing
equipment provides us with valuable expertise in a new business that fits very
well with our existing organization", Lemley commented.

      Stephen Romano, Vice President for Corporate Development with American
Ecology, will serve as President of the Company's Idaho operations, which
include the newly acquired subsidiary.

       "This unique combination of environmentally protective waste treatment
technology, desert disposal capacity and client site services favorably expands
American Ecology's capabilities", Lemley concluded.

      On Friday, February 2, at 10 am Mountain Time, Lemley will host an
investor conference call to discuss the acquisition and respond to questions.
Participants are invited to call (800) 553-9545. The participation code is
