Waite (BWaite(�)chevron.com) <br /> Subject: RE: 3978 S Hwy 99 - Domestic Well Analyses <br /> Lisa- <br /> It is my understanding that domestic well DW-1 was sampled last year due to the property owner's concerns regarding <br /> the 'data gap'between 2006 and 2012. Analytical results from samples collected during 2005, 2006, and 2012 indicate <br /> that this well has not been impacted (all results are 'non-detect').The cross gradient location of this well to the site <br /> further indicates that the well will not be impacted by any of the former site activities.Could you please clarify why <br /> SJEHD would like to have DW-1 sampled again? <br /> Thank you, <br /> Justin Sobieraj, PG i Senior Geologist{justin.sobierajt�arcadis-us.com <br /> ARCADIS U.S., Inc. 2000 Powell Street, 7th Floor Emeryville, California 94608 <br /> T: 510.596.9684 1 M:415.858.8310 <br /> www.arcadis-us.com <br /> ARCADIS, Imagine the result <br /> Please consider the environment before printing this email. <br /> YEA sf a ';f� Q <br /> Ali <br /> From: Lisa Medina [EH] [mailto:Imedina(@sjcehd.com] <br /> Sent: Tuesday, July 23, 2013 2:17 PM <br /> To: Sobieraj, Justin <br /> Cc: Nickens, Amber <br /> Subject: 3978 S Hwy 99 - Domestic Well Analyses <br /> Good Afternoon <br /> Discussion was made in the past regarding the testing of the domestic water well located 15 feet north of the site <br /> property line.We understand that the well was tested for BTEX over the past year.'The EHD would like to respectfully <br /> request that the domestic water well be tested again for BTEX, Motor Oil and Diesel prior to issuance of the final closure <br /> letter.
