Werner <br /> Subject: 239 S. Stockton Street <br /> Kevin, <br /> 1 <br /> Here are a few sample workplans. I tried to find sites somewhat similar to the Madsen Dairy,with simple preliminary site <br /> investigations. I would recommend you consider at least three direct push soil borings to surround the area of the reported <br /> dirty soil sample, and collect grab groundwater samples from each. I checked some reports from Thiemanns,the most <br /> current data we have is from October 2009 and groundwater was at 30 feet below grade. It may be a bit more shallow now, <br /> due to the rains, but the most shallow it has been since 2002 is 26 feet below grade. <br /> I have also included a list of environmental consultarits that do work in this area, but I cannot recommend any one in <br /> .particular. Please call or email if you have any further questions. I will be preparing the directive letter. <br /> Thank you, <br /> Lori Duncan, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> Idunca_n_a@sjcehd.com <br /> (209)468-0337 phone <br /> (209)468-3433 fax <br /> 2/22/2010 <br />
