CE/NFELpER <br /> 4 . 2 . 1 Chemical Analysis of Groundwater Samples <br /> The groundwater samples were submitted under chain-of-custody control to Test America of <br /> Morgan Hill , California . Test America is certified by the State of California Department of <br /> Health Services (DHS) to conduct the requested analyses. Samples were analyzed on a <br /> regular laboratory turnaround schedule , requiring approximately 10 working days for receipt of <br /> analytical data. <br /> The groundwater samples collected from the monitoring wells were analyzed for Nitrate as N <br /> by EPA Method 300 . 0 . In addition , samples collected from the dewatering discharge on an <br /> approximately weekly basis were also analyzed for nitrates . <br /> 4.3 SURFACE WATER MONITORING <br /> Visual inspections of the nursery were generally made on approximately a daily basis by <br /> nursery personnel at points at which surface runoff may leave the nursery and enter Potter <br /> Creek (directly or indirectly) . These discharge points include, but are not limited to: <br /> 1 ) the culverts/pipes from the tailwater holding pond <br /> 2) the roadside drainage ditch along the east side of Escalon Bellota Road <br /> 3) the drainage as it enters Norman 's property from the south <br /> Inspection records indicate whether the gates on the discharge culverts/pipes from the <br /> tailwater pond (Basin B) were opened or closed . <br /> Kleinfelder initially provided Norman's Nursery personnel with training on the surface water <br /> monitoring and sampling . Additional periodic follow-up training and occasional sampling are <br /> also conducted by Kleinfelder. Samples were collected by Norman's Nursery personnel and <br /> analyzed as indicated below. <br /> The samples were then transported by Norman 's Nursery personnel to Kleinfelder's office in <br /> Stockton , California , and subsequently picked up by a Test America courier. All original <br /> analytical reports were submitted by the laboratory to Kleinfelder. <br /> 117226.E02/STO13R0176 Page 19 of 40 January 31 , 2013 <br /> Copyright 2013 Kleinfelder <br />
