data, the highest water level in the last 10 years was measured <br /> at about 27' bg1 at this site. Groundwater was located at about <br /> 53' below grade during purging & sampling operations conducted in <br /> October, 1994 <br /> PRIOR USE OF REMQYED UST' S: <br /> The site had been the location of a gasoline station for many <br /> Years; the removed tanks had been used for dispensing gasoline <br /> and storing waste oil . The property is presently being used as <br /> an automotive tune-up & repair facility; the dispensing pumps & <br /> associated piping were removed along with the tanks. There are <br /> no records available concerning the dates that the tanks were <br /> installed. <br /> SUMMARY OF PRIOR „MK DONE: <br /> December. 1986 - Application filed by Western Meter Service to <br /> remove two (2) 3, 000 gallon gasoline tanks and one ( 1 ) 150 gallon <br /> waste oil tank from the property. <br /> April . 1987 - The 3 tanks were removed and soil samples taken <br /> Laboratory analysis of samples from beneath the gasoline tanks <br /> were below detection limits, but the soil sample from the waste <br /> oil site revealed the presence of ethylbenzene, toluene, xylene, <br /> TPH-G, & motor oil . Refer to TABLES__I �& II for details <br /> June. 1987 - Site of removed waste oil tank was deepened to about <br /> 8 1/2' with a backhoe. A sample was taken at that depth and <br /> analyzed for TPH; gasoline was measured at 1500 mg/kg, & motor <br /> oil at 4200 mg/kg; diesel & kerosene were below detection limits <br /> Refer to TABLE III for details <br /> August, 1987 - Waste oil tank site reentered & deepened to 13. 5' <br /> under direction of the EHD. A soil sample taken at that depth <br /> was analyzed for benzene, toluene, xylene, & TRPH Motor oil was <br /> measured at 3100 mg/kg; all others were below detection limits. <br /> Refer to TABLE IV for details. <br /> Qrtgber. 1989 - Site was reentered & soil sample taken at <br /> approximately 23' below grade. Laboratory analysis showed that <br /> oil, as motor oil, was present at 280 mg/kg. This work was not <br /> witnessed by the County EHD. <br /> Septgmber. 1993' - Workplan submitted by Wm J. Hunter & Assoc. , <br /> (WJH, ) to place four (4) 30 foot deep soil borings. Refer to the <br /> PAR, dated January 4, 1994, prepared by WJH, for a copy of that <br /> workplan <br /> Octob!jr 27 & ED. 1993 -- work was performed under the direction of <br /> 3 <br />
