IW-3 is not approved for routine sampling as long as you are <br /> using it as a remediation well . It is my understanding the oxygen system is in operation . <br /> The semi-annual event should be conducted during the first quarter. Wells approved to be sampled semi-annually <br /> are: MW-513 , MW-7 , MW-8 and AS- 1 . In addition , EHD approved sampling DPE-1 (SVE-1 ) at two different depths <br /> at the next event. After first quarter 2010 , DPE-1 (SVE- 1 ) is on the annual (third quarter) schedule. <br /> To summarize: <br /> First Quarter 2010- semi-annual: MW-513, MW-7, MW-8, AS- 1 , DPE-1 - 15, DPE-1 -23 . <br /> Third Quarter 2010- annual : MWA through MW-8 , AS-1 , DPE-1 . <br /> Lori <br /> From: Arron Wilder [mailto:AWilder@clearwatergroup.com] <br /> Sent: Monday, January 11, 2010 1 :45 PM <br /> To: Lori Duncan [EH] <br /> Cc: Olivia Jacobs; Erik Lervaag; Jim Jacobsl; Gavin Fisco; Sandy Young <br /> ubject:1817-Sout"resno Ave.,-Stockton,-CA—Barnes-Trucking-- 2010-GW Sampling-Info <br /> Dear Ms. Duncan , <br /> I am sending this short table that shows the scheduled analytical and groundwater sampling frequency for <br /> the 2010 year.
