TABLE I <br /> M. SANCHEZ , 1876 COUNTRY CLUB DRIVE , STOCKTON, CA <br /> SUMMARY OF RESULTS OF LABORATORY ANALYZES OF GROUNDWATER SAMPLES <br /> FROM THE THREE MONITORING WELLS LOCATED ON THE PROPERTY. <br /> Samples taken by Del-Tech Geotechnical & analyzed by FGL <br /> laboratory <br /> METHODS: BTEX - EPA 602; TPH-G - EPA 801511; EPA 501 <br /> UNITS: BTEX, ug/L; TPH-G, mg/L; EPA 501 , ug/L <br /> DETECTION LIMITS: BTEX - 0. 3; TPH-G - 0. 05; EPA-501 0. 5 <br /> NOTE: Detection limits for samples taken 8/25/94 from MW-1 & MW-3 <br /> for BTEX increased to 60. 0 ug/1 due to sample matrix inter- <br /> ferences. Detection limit for TPH--G in MW-1 increased to 0. 1 due <br /> to matrix interferences. <br /> RESULTS RESULTS RESULTS RESULTS RESULTS RESULTS <br /> COMPONENT 4/21/93 7/23/93 11/1/93 1/26/94 4/29/94 8/25/94 <br /> Benzene 8250 13000 16000 )6300 8500 10000 <br /> Toluene 275 3300 1000 490 1000 270 <br /> EBenzene 650 2300 1700 650 1500 900 <br /> Xylene 2250 13000 8300 2700 5400 3200 <br /> TPH-G 23. 6 23. 0 28. 0 21 . 0 17. 6 23 <br /> Bromodichloromethane ND NT NT <br /> Bromoform NO NT NT <br /> Chloroform ND NT NT <br /> • Dibromochloromethane NO NT NT <br /> Total Trihalomethanes NO NT NT <br /> MONITORING WELL #2 <br /> RESULTS RESULTS RESULTS RESULTS RESULTS RESULTS <br /> COMPONENT 4/21193 7/23/93 11/ 1/93 1/26/94 4/29/94 8/25/94 <br /> Benzene 2. 2 720 650 ND 13. 0 1. 8 <br /> Toluene NO 210 ND 3. 5 NO 1 . 1 <br /> EBenzene ND 82. 0 NO 47. 0 ND 3. 6 <br /> Xylene NO 270 NO 59 ND 2. 6 <br /> TPH-G ND 1. 9 3. 3 0. 63 0. 41 . 71 <br /> MONITORING WELL ft <br /> RESULTS RESULTS RESULTS RESULTS RESULTS RESULTS <br /> 4/21/93 7/23/93 11/ 1/93 1/26/94 4/29/94 8/25/94 <br /> COMPONENT <br /> Benzene 730 2200 3300 2100 1000 2200 <br /> Toluene 35. 0 600 120 53. 0 30. 0 ND <br /> EBenzene 115 400 390 250 97. 0 240 <br /> Xylene 240 1300 140 240 40.0 190 <br /> TPH-G 4. 0 6. 5 6. 2 7. 7 2. 6 6. 1 <br /> Bromodichloromethane NO NT NT <br /> Bromoform ND NT NT <br /> Chloroform NO NT NT <br /> Dibromochloromethane ND NT NT <br /> • Total Trihalomethanes NO NT NT <br /> WJ.HUNTER&ASSOC. <br /> SUMMARY OF LABORATORY ANALYZES FROM <br /> 2220 LOMA VISTA DRR..
