Gabriel Gonzalez [EH] <br /> From: Scott <SBittinger@stratusinc.net> <br /> Sent: Friday, March 06, 2015 6:48 AM <br /> To: Gabriel Gonzalez [EH];Jennifer Delgado <br /> Subject: RE: Groundwater Monitoring and Sampling Event <br /> Gabriel: We will make VW-2 a semi-annual sampling well and then sample MW-6 annually, during the third <br /> quarter. Sampling of VW-2 could be useful for evaluating ozone system performance, so I think it's worthwhile sampling <br /> it twice per year. I am fine with sampling MW-6 once per year. <br /> From: Gabriel Gonzalez [EH] [mailto:aagonzalez(alsjcehd com] <br /> Sent: Thursday, March 05, 2015 4:01 PM <br /> To: Jennifer Delgado <br /> Cc: Scott <br /> Subject: RE: Groundwater Monitoring and Sampling Event <br /> Hi Jennifer, <br /> Thank you for the information. From the twelve 102 S Wilson Way wells listed in your email below, according to Stratus <br /> reports the following eight wells are on a MRP approved by the RWQCB: MW-2, 5, 8, 10, 12, 13B, 17C, and VW-1.This <br /> leaves four wells(MW-1, 6, 15B, and VW-2)which should follow the EHD approved schedule outlined by letter dated 23 <br /> February 2009. Given that MW-6 and VW-2 are listed in the letter as"annual sampling' wells and both have been <br /> sampled in the 3'd Quarter 2014(September 2014), it seems MW-6 and VW-2 are not due for sampling this 1ST quarter <br /> 2015. 1 see in Stratus reports that neither MW-6 nor VW-2 are listed as annual sampling wells in the"Frequency of <br /> Groundwater Sampling" section,which doesn't agree with the letter. <br /> Please clarify the 102 S Wilson Way schedule. If there is more recent EHD sampling directive than the attached 2009 EHD <br /> letter, please inform me. <br /> Sincerely, <br /> Gabriel Gonzalez <br /> From: Jennifer Delgado [mailto:]DelgadoCalstratusinc.net] <br /> Sent: Thursday, March 05, 2015 8:07 AM <br /> To: Gabriel Gonzalez [EH] <br /> Cc: Scott <br /> Subject: RE: Groundwater Monitoring and Sampling Event <br /> Hi Gabriel, <br /> For the site located at 102 South Wilson Way, we are sampling the following wells: MW-1, MW-2, MW-5, MW-6, MW-8, <br /> MW-10, MW-12, MW-13B, MW-15B, MW-17C,VW-1 and VW-2.
