The test performed in November 1990 was for <br /> total Iead using EPA method 6010. The test for soluble lead is a waste extraction test using <br /> EPA method-7421. If the lead is not soluble then groundwater is not.threatened and site <br /> certification for tank #1625-05 can occur. <br /> As discussed in telephone conversations the soil sample can be collected by drilling or by <br /> excavating ten feet or more below ground surface. Drilling must be completed by a C-57 <br /> licensed driller under PHS/EHD permit and inspection. A plan of the work must be <br /> submitted to.PHS/EHD with the request for service form enclosed and the $390 (five hour <br /> minimum) oversight fee. <br /> If you have any questions, contact Margaret L.agorio, Senior RENS; at (209) 468-3449. <br /> Jog Khanna,. 1D., M.P.H. <br /> Health Off-l' <br /> ne A.
