   Item 2.  Acquisition or Disposition of Assets

       On October 6, 1997 (the "Closing Date"), Thermo Remediation Inc. (the
   "Company") sold its 50% limited liability company interest in
   RETEC/TETRA, L.C., a Texas limited liability company (the "Joint
   Venture"), to TETRA Thermal, Inc. (the "Buyer"). Prior to this sale, the
   Buyer held the other 50% limited liability company interest in the Joint
   Venture. The Joint Venture, established in August 1992, engages in the
   business of installing and operating systems to process hazardous and
   nonhazardous wastes at petroleum refineries located primarily in the Gulf
   Coast region of the United States.
        The selling price for the Company's interest in the Joint Venture
   was $8,825,000 in cash. The selling price is subject to post-closing
   adjustments in the event of certain further sales of interests in the
   Joint Venture or its assets within six months after the Closing Date.
   Under the terms of the agreement originally establishing the Joint
   Venture, either party to the agreement had the right to propose a value
   for a 50% interest in the Joint Venture (the "Proposing Party") and to
   cause the other party (the "Electing Party") either to (i) buy the
   Proposing Party's interest in the Joint Venture at such price or (ii)
   sell the Electing Party's interest in the Joint Venture to the Proposing
   Party at such price. The selling price was proposed by the Buyer and the
   Company elected to sell the Buyer its interest in the Joint Venture at
   such selling price.
        The disposition was made pursuant to a Purchase and Sale Agreement
   (the "Agreement") executed on October 6, 1997, by and among the Company's
   Remediation Technologies, Inc. and RETEC Thermal, Inc. subsidiaries, as
   well as the Buyer and its TETRA Technologies, Inc. affiliate. In the
   Agreement, the Buyer and its affiliate agreed, subject to certain
   exceptions, to indemnify the Company and its subsidiaries against claims
   arising out of the operations, debts and liabilities of the Joint Venture
   arising both before and after the Closing Date. The terms of the
   Agreement were determined by arms' length negotiation among the parties.

             (b) Pro Forma Condensed Financial Information

       The following unaudited pro forma condensed financial statements set
   forth the results of operations for the fiscal year ended March 29, 1997,
   and the three months ended June 28, 1997, as if the sale of the Company's
   investment in the Joint Venture had occurred at the beginning of fiscal
   1997. The unaudited pro forma condensed balance sheet sets forth the
   financial position as of June 28, 1997, as if the sale of the Company's

   future operations or the actual results that would have occurred had the
   sale of the Company's investment in the Joint Venture been consummated at
   the beginning of fiscal 1997. These statements should be read in

    Note 1 - Basis of Presentation

       As described in Item 2 of this Form 8-K, the selling price is based
    on an estimate of the fair market value of the net assets sold and is

    would cause the Company to believe that the final selling price will be
    materially different than the preliminary estimate.
