PHS/EHD has the following comments for your consideration. <br /> PHS/EHD agrees with the recommendations presented in the "Addendum". The installation of a <br /> replacement monitoring well is necessary to assess groundwater quality and gradient. The proposed <br /> investigation to define the lateral extent of soil contamination, included a minimum of three hand augered <br /> soil borings drilled to a depth of approximately 8 feet. Please submit a work pian and a permit application <br /> for the drilling of a monitoring well and soil borings by August 30, 1992. <br /> Stockpiled soil consisting of approximately 1,200 cubic yards resulted from the January 2990 tank removal <br /> and subsequent December 1991 re-excavation. The stockpiled soil is being stored on-site. <br /> The "Addendum" recommended that the stockpiled soil be sampled for characterization and either <br /> disposed of in a Class III landfill or treated on-site followed by off-site disposal. Please submit a sampling <br /> and soil remedial treatment plan by July 27, 1992. Summer weather conditions are.favorable for microbial <br /> treatment of contaminated soil. <br /> If you have any comments or questions or to schedule the next quarterly sampling by July 16, 1992, please <br /> contact Mary Meays, REHS,of my staff at (209) 468-0337. <br /> Jogi Khanna, P.H. <br /> Health O r <br /> curie A.
