          Re:  Sevenson Environmental Services, Inc. - Registration
               Statement on Form S-8

Gentlemen:

          With respect to the Form S-8 Registration Statement of Sevenson
Environmental Services, Inc. (the "Company"), covering the registration of
280,000 shares of Common Stock, $.01 par value ("Common Stock") of the
Company, we have examined and are familiar with the Company's Certificate
of Incorporation, By-laws, resolutions of its Directors and such other
documents and corporate records and proceedings relating to the
organization of 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 New
               York.

          2.   The 280,000 shares of Common Stock 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 LLP

Gentlemen:

          With respect to the Form S-8 Registration Statement of Sevenson
Environmental Services, Inc. (the "Company"), covering the registration of
280,000 shares of Common Stock, $.01 par value ("Common Stock") of the

organization of 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 New
               York.

          2.   The 280,000 shares of Common Stock 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,
