The groundwater samples will be analyzed for TPHG <br /> and MTBE by EPA Method 8015 modified with purge and trap <br /> preparation 5030 (GC/FID) with detection limits of 50 ug/1. EPA <br /> Method 602 will be utilized for BTEX with a detection limit of <br /> 0 . 5 ug/1 as required by the SJCEHD. <br /> Task 6 <br /> JPCA�s all measure the: depth th to groundwater and calculatel' a <br /> �h p g <br /> gradient. <br /> Task 7 <br /> A site map or maps to scale of the subject site and areas <br /> impacted showing the location ofthe former UST area, elevation <br /> contours, gradients, near by surface waters, streets, structures <br /> and underground utilities. <br /> Task 8 <br /> A report, signed by the Certified Engineering Geologist, John N. <br /> Alt, will include a summary of the field work, boring logs, COC <br /> documentation, certified analytical results, conclusions and <br /> recommendations, with 'a rational why conditions remaining at the <br /> site will not adversely impact water quality, health or other <br /> beneficial water usage, in accordance with the "Recommendations <br /> for Closure Requests" of Underground Storage Tank Sites" . The <br /> report will be submitted to the client and the SJCEHD. <br /> Please call me when you get an opportunity. <br /> Sincerely, <br /> J hn P. Cummings <br /> r <br /> 3 <br />
