i <br /> removed diesel UST' s & over 200 feet from the excavated septic <br /> system, measured 0 4 ug/L of xylene and 410 ug/L TEPH from the <br /> water sample at 221 . <br /> The water sample taken from SP-4, located inside the property <br /> next to the office building, and about 50 ' south of MW-1, <br /> revealed 0 3 ug/L of xylene & 360 ug/L of TEPH. <br /> SP-5, located in the parking area between the truck scales and <br /> the removed UST' s, did not show any BTEX or TPHg in the water <br /> sample, but TEPH was measured at 517 ug/L. <br /> SP-7, located approximately 100 feet north of the removed UST' s, <br /> and about 50 ' east from the above ground tank location, revealed <br /> 2 0 ug/L of xylene & 126 ug/L of TEPH in the groundwater sample <br /> However, as discussed earlier, benzene, toluene, & xylene were <br /> detected in soil samples taken at 15 ' & 20, and toluene & xylene <br /> in the soil sample from 251 . <br /> The water sample from SP-8, located about 30 ' north of MW-3, <br /> measured xlyene at 0 .3 ug/L, & 327 ug/L TEPH. Soil samples taken <br /> from this probe hole were non-detect for all tested compounds <br /> SP-9, located about 40 ' north of the removed waste oil UST, <br /> measured only xylene at 0 .3 ug/L; all other tested substances <br /> were non-detect . <br /> The water sample taken from SP-10, which was located along the <br /> west property line and about 75 ' north of MW-2 , measured benzene <br /> at 3 . 0 ug/L, toluene at 2 . 0 ug/L, ethylbenzene at 2 0 ug/L, & <br /> xylene at 2 . 0 ug/L TPHg was measured at 114 ug/L, the only <br /> other well besides SP-6 to show that compound. TEPH as motor oil <br /> was 1640 ug/L, the highest measured in any of the 10 soil probes . <br /> MTBE was below detection levels in all samples analyzed. <br /> The laboratory sheets and chains of custody are included at the <br /> back of this report . <br /> CONCLUSIONS : <br /> Based upon all of the work performed to date at this site, the <br /> following conclusions appear valid: <br /> I . Soil & groundwater are impacted over the entire area covered <br /> by work done to date. <br /> 2 . There appear to be at two, and possibly three offsite sources <br /> of contamination - (1) the Nomellini property to the east, which <br /> has severely impacted the groundwater at least as far as MW-4; <br /> 5 <br />
