If you look at the document they reference , the " Updated Corrective Action Plan <br /> In - Situ Chemical Injection " You will see they propose ' dewatering ' the area , but not dual <br /> phase . In meeting with us they further explained that if this is done , they will use <br /> temporary , shallow dewatering points . <br /> I think the main idea here is that they are proposing ISCO . <br /> Lori Duncan , Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> lduncan@sjcehd . com <br /> ( 209 ) 468 - 0337 phone <br /> ( 209 ) 468 - 3433 fax <br /> - - - - - Original Message - - - - - <br /> From : Kirk Larson [mailto : KTLarson@waterboards . ca . gov] <br /> Sent : Monday , May 10 , 2010 10: 55 AM <br /> To : Lori Duncan [EH] <br /> Subject : Re : FW : UST Fund Reviews <br /> Page 5 , first quarter 2010 , they recommended both DPE and chemical injection/ air sparge . <br /> Sorry I missed the second half .

They RP has proposed , and is preparing a bench scale test and <br /> pilot study , to do ISCO . <br /> If you have a document in which the RP is proposing to do dual phase extraction at this <br /> site , I would appreciate seeing it , as it has not been submitted to me . <br /> sincerely , <br /> Lori Duncan , Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> lduncan@sjcehd . com <br /> ( 209 ) 468 - 0337 phone <br /> ( 209 ) 468 - 3433 fax <br /> - - - - - Original Message - - - - - <br /> From : Lori Duncan [EH] <br /> Sent : Tuesday , April 20 , 2010 8 : 04 AM <br /> To : ' Kirk Larson ' <br /> 2 <br />
