               Statement on Form S-8

Gentlemen:

          With respect to the Form S-8 Registration Statement of
the Sevenson Environmental Services, Inc. 1989 Incentive Stock
Plan (the "Plan"), covering the registration of an additional
100,000 shares of Common Stock of Sevenson Environmental

documents and proceedings that we have considered necessary for
the purpose of this opinion.

          Based upon such examination, we are of the opinion
that:

          1.   The Company has been duly organized and is a
               validly existing corporation under the laws of the
               State of Delaware.

          2.   The additional 100,000 shares of Common Stock
               which may be issued by the Company under the Plan
               have been duly authorized and, when issued in
               accordance with the terms of the Registration
               Statement and the Plan, will be validly issued,
               fully paid and non-assessable.

          We hereby consent to the filing of this opinion as an
Exhibit to the Registration Statement.

                              Very truly yours,

                    PHILLIPS, LYTLE, HITCHCOCK, BLAINE & HUBER

the Company, proposed issuance of securities and the adoption of
the Plan by the Company.  We have also examined such other
documents and proceedings that we have considered necessary for
the purpose of this opinion.

          Based upon such examination, we are of the opinion
that:

          1.   The Company has been duly organized and is a
               validly existing corporation under the laws of the
               State of Delaware.

          2.   The additional 100,000 shares of Common Stock
               which may be issued by the Company under the Plan
               have been duly authorized and, when issued in
               accordance with the terms of the Registration
               Statement and the Plan, will be validly issued,
               fully paid and non-assessable.

          We hereby consent to the filing of this opinion as an
Exhibit to the Registration Statement.

                              Very truly yours,
