Wm. Hunter, RG, using Spectrum Exploration auger rig & personel . <br /> Refer to the above referenced SAR for a detailed description of <br /> that work, The locations of those soil borings are shown on PLATE <br /> 11.. Laboratory analyzes from soil samples taken during the <br /> Placement of the soil borings revealed that A" samples were <br /> either below detection limits , or within acceptable levels, for <br /> chlorinated solvents, (EPA 8010, ) ICAP metals, & TPH-D. BTEX & <br /> TPH--G were below detection limits in &,U samples except soil <br /> boring #2 at 38' . The results of those analyzes are shown on <br /> January. 1994 - A report entitled "PROBLEM ASSESSMENT REPORT <br /> COVERING SOIL CONTAMINATION INVESTIGATION" , was prepared by WJH & <br /> submitted to the San Joaquin County EHD covering the field work <br /> conducted in October, 1993, and discussing the results Refer to <br /> that document for complete details of that work <br /> FAflirggry 28 . 199.4 - Correspondence from San Joaquin Co. EHD <br /> recommended further assessment and/or re-excavation of the former <br /> waste oil tank site. <br /> t <br /> Agggst 17 . 19a4 - WJH prepared a workplan to place one (1 ) soil <br /> boring to a depth of 40' in the center of the site of the removed <br /> waste oil tank. <br /> Sej tember 90 . 1994 - One ( 1) 2" diameter monitoring well was <br /> placed on the property; details of that work are covered in the <br /> report prepared by WJH titled "Interim Report and Results of <br /> Groundwater Investigation" , dated October 31, 1994 . Laboratory <br /> results revealed the presence of BTEX & TPH-G in both soil & <br /> water samples below 36' . Refer to TABLES VIJI& IX for a summary <br /> of those results <br /> NELLS <br /> NOTES. (1) Locations of underground utilities will be identified <br /> prior to beginning the work <br /> (2) All drilling & completion operations will be done <br /> under the direction of a geologist from Wm J. Hunter <br /> & Associates. <br /> 1 . Mobilize properly licensed auger rig & support truck equipped <br /> with sufficient clean hollow-stem augers to complete each well <br /> without the necessity of decontaminating equipment The tenta- <br /> tive locations of the two wells are shown on PLATE IV, the final <br /> sites may vary slightly due to interference from underground <br /> utilities or overhead power lines A drilling permit application <br /> will be submitted & approved prior to commencing operations . <br /> Drilling bids are currently being solicited, a contractor has not <br /> 4 <br />
