Montpelier, OH 43543 <br /> Attention: Mr, Dale Kuenzli <br /> RE: Subsurface investigation <br /> Fertilizer & Petroleum <br /> Facility <br /> Edgerton, Ohio <br /> �• - Alt & Witzig File: N0278 <br /> Gentlemen: <br /> Alt & Witzig is pleased to present an evaluation of the data <br /> collected during our subsurface investigation at the above <br /> referenced facility. We are enclosing three (3 ) copies of our <br /> report. Additionally, please find enclosed a preliminary <br /> remedial outline where we have compared several recognized <br /> techniques. <br /> This project was initiated in response to the results <br /> indicated in a preliminary investigation for a potential <br /> purchaser of the property (Alt & Witzig File: N0229 ) . The <br /> preliminary project consisted of several borings in areas <br /> identified as potentially containing contaminated soils. The <br /> borings indicated relatively low levels of petroleum hydrocarbon <br /> in all areas except near the facility's underground storage <br /> tanks. <br /> In borings B-3 and E-4 near the tanks, relatively high levels <br /> of contamination were indicated from ten (10) to sixteen (16 ) <br /> �,. feet below the ground surface. Confirmatory laboratory analysis <br /> indicated a total petroleum hydrocarbon (TPH) presence of 232 <br /> Parts per million (ppm) . <br /> The current investigation consisted of installing several <br /> borings and two monitoring wells around the property in an effort <br /> to delineate the extents of contamination. it appears that an <br /> area of approximately 60' x 75' has been contaminated. <br /> Additionally, the groundwater table has also been contaminated. <br /> OFFICES: <br /> ..
