If you are not <br /> comfortable with his answers, then you and your consultants may present another destruction method to our <br /> agency. The method must be able to remove all the contents of the CMT monitoring well from the borehole. <br /> Sonic over drilling had the next best result compared to using explosives. <br /> I have attached a photo of a portion of a CMT well that was blasted with 50 grains detonation cord and then <br /> drilled out of the borehole. This was done at an active gas station last summer without incidents. <br /> Mr Schwedler, <br /> Can you please address the owner's concerns he notes below in the attached e-mails. <br /> Thank you for your insight, <br /> Adrienne <br /> Adrienne Ellsaesser, PEH5 <br /> Program Coordinator <br /> San Joaquin County <br /> Environmental Health Department <br /> 1868 East Hazelton Avenue <br /> Stockton , CA 95205 <br /> Ph (209) 468-0343 <br /> Fax (209) 468-0341 <br /> ael Isaesser@s icehd.com <br /> From: David Atwater fmailto:dbatwater@vandepol.us] <br /> Sent: Wednesday, November 21, 2012 11:06 AM <br /> To: Barton, Jim@Waterboards; tcuellar@advgeoenv.com; Adrienne Ellsaesser [EH]; Nuel Henderson [EH] <br /> Cc: George V.
