J !f <br /> } 3. <br /> Ric Notini � <br /> Page 2 <br /> E � <br /> The problem assessment report should evaluate remedial alternativles. One criteria for preparation of a <br /> problem assessment report is that the soil and groundwater contamination has been defined. To date <br /> neither soil nor groundwater contamination have been physically defined at this site. <br /> Both former leaking underground storage tanks on the property, USI'T#1 and UST#2,were located <br /> adjacent to buildings, 1515 West Weber and 1325 West Weber, respectively. The extent of soil <br /> contamination beneath these buildings has not been defined. Therefore, consideration should be given to <br /> I the placement of slant borings to define the contamination beneath;both buildings, 1515 West Weber and <br /> 1325 West Weber. Additionally, soil contamination evidenced during the installation of monitoring wells, <br /> MW1A and MW3A, indicate that soil contamination has not been defined�in those directions. Levels of <br /> groundwater contamination in MW1A and the problems previously discussed with the screened intervals of <br /> MW3A and MW4A indicate that groundwater contamination has not been!defined. <br /> Please submit a work plan for further investigation of the extent of soil and groundwater contamination by <br /> fJanuary 25, 1993. <br /> Please be informed that PHS/EHD inspections of sampling events are an important aspect of local <br /> regulatory oversight. PHS/EHD should be provided a minimum of 48 hours notice prior to any site activity ' <br />�II including sampling. The next quarterly monitoring event should be scheduled by December 1, 1992. <br /> 1 # <br /> If you have any questions, comments, or to schedule a site inspectioin, please contact Mary Meays, RENS, <br /> of my staff at (209)468-0337. 1 <br /> Jogi Khanna, M D, M.P.H. <br /> Health Officer <br /> rie A.
