Box 2009 ENVPT2RMITISERVICES <br /> Stockton, CA 95201 <br /> Dear Pam: <br /> Sorry we traded messages this morning and couldn't make <br /> contact. I an going to be at a California Manufacturers <br /> Association conference the rest of the week (leaving at noon <br /> today) so I guess this is the best way to get my message to <br /> you. <br /> On Friday, when I left a message for you, I had two subjects <br /> that I wanted to discuss: 1) that I had selected a bidder for <br /> removal of the courtyard tanks and 2) that the analyses of <br /> samples taken from monitoring wells around the large oil tank <br /> in June came back positive (although just above the detection <br /> level) for total petroleum hydrocarbons. Unfortunately, when <br /> you called back on Monday, item 2 slipped my mind. <br /> 5Ao kl IV ppM <br /> I am enclosing copies of ;sults. FGL analyzed for <br /> TPH at a detection level f .5ppb.> All of the prior analyses <br /> performed by other laborat had been using a detection <br /> level of 1.0. As you can see, the results for Monitoring <br /> Well 01 were 1.1, Well #2 was at .9, well #3 was also at .9 <br /> and Well #4 was dry. This "positive" finding could be due to <br /> the increased rainfall, the spill that we had in February <br /> when the tank was overfilled or possibly have been there all <br /> along, but just under the previous detectable levels:. <br /> we are inclined to have the wells resampled and tested again <br /> at least for TPH, but before doing so, I wanted to get an <br /> indication from you of the seriousness with which the County <br /> would view a result of this magnitude. <br /> Please give me a call after you have reviewed the attached <br /> information. You can either leave a message on my voice mail <br /> or if you wish to talk to me in person, I will be back in the <br /> office on Monday morning from 7:30 AM until 11:00 AM. <br /> Mike kogge <br />
