Working To Restore Nature <br /> direction of flow cannot be specifically determined from the on-site wells, the direction can be <br /> safely assumed to be consistent with the nearby saes Monitoring well MW2 is appropriately <br /> located to monitor groundwater downgradient from the excavation and MW3 is adequate for <br /> upgradient observations <br /> The water samples collected from wells MW2 and MW3 on October 1, 1993 were analyzed for <br /> benzene, toluene, ethylbenzene and xylenes (BTEX) by EPA method 8020, total petroleum <br /> hydrocarbons as gasoline (TPHG) and total petroleum hydrocarbons as diesel (TPHD) by <br /> modified EPA method 8015 Dissolved petroleum hydrocarbons were not detected at or above <br /> method detection limits in monitoring wells MW2 or MW3 Analytical data is presented on <br /> Table 2. The laboratory data sheets, chain-of-custody, and monitoring data are included as <br /> Attachment 2 <br /> If you have any questions or comments please contact our Escalon office at 2091838-3507 <br /> Respectfully, <br /> RESNA Industries Inc <br /> iLois Frantz <br /> Protect Geologist <br /> Greg P Stahl <br /> CA Registered Geologist No 5032 <br /> LF/gk <br /> Attachments <br /> pc Nick Kosta, BJJ Trucking <br /> Elizabeth Thayer, RWQCB - Central Valley Region <br />• <br /> 4QR-1993 PNL <br />
