Page 2 of 2 <br /> I would like to compare the analytical results from the low-flow sampling method verses the purge-and-sample <br /> method using a disposable bailer before deciding whether to use the low-flow method for sampling all of the <br /> monitoring wells at the Frontier Transportation Inc. site. Please use both methods (first the low-flow method <br /> followed by the disposable bailer method)when collecting groundwater from monitoring wells MW-1, MW-9, MW- <br /> 17, MW-19, and MW-25 during the next sampling event scheduled for October 25-27, 2010. If the analytical <br /> results from the two methods are comparable, then the low-flow method can be used during future sampling <br /> events at this site beginning in 2011. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 600 East Main Street <br /> Stockton,California 95202 <br /> Phone: (209)468-9852 <br /> Fax: (209)468-3433 <br /> Email: ym-ccartnea>sjcehd.com <br /> From: Olivia Jacobs [ma!Ito:OJacobs@clearwatergroup.com] <br /> Sent: Tuesday, October 12, 2010 5:29 PM <br /> To: Vicki McCartney [EH] <br /> Cc: larryw@amiadini.com; kpope@reliable-env.com <br /> Subject: Site #2251 <br /> Vicki <br /> Kevin wanted to know whether you would be amienable to low-flow sampling at this site, as opposed to <br /> purge and bailer sampling? <br /> Please advise.
