Box 2009 <br /> I Stockton, CA 95201. <br /> UNION ICE, 1320 WEST WEBER STREET, STOCKTON, SANS°JOAQI"IN COUNTY <br /> I have reviewed the file for the Union Ice site on Weber Street in Stockton. <br /> I also reviewed the recent report, "Phase II - Re'port ?of Findings" , dated <br /> i' 28 May 1991 , prepared by WHF Environmental and 'Henkle ;',& Associates. Based on <br /> analytical results showing non-detectable levels �of contaminants in all wells <br /> since April 1991, WHF and Henkle have recommended several soil borings to <br /> delineate soil contamination and another year of ,:quarterly ground water <br /> monitoring to be followed by closure if .all . samptes' are non-detectable, <br /> i <br /> k The following information is missing from our files:. . <br /> 1. A Work Plan dated 15 June 1990 by WHF and Henkle; <br /> 2. Well logs for monitoring wells MW-1S, MW-1D, and MW-65, installed by <br /> URS, the previous consultant; and <br /> 3. The results of the soil vapor survey. The �28 May 1991 report states <br /> that the vapor survey was done in May' 1990 `and the results submitted in <br /> a report to San JoaquinCounty in June 1990. :In our file, the "Report <br /> of Findings - Phase I" , dated 14 June 1990,' did not contain the soil <br />` vapor survey results'. <br /> l _. - <br />' In February 1991 , two new wells were installed: The 28 May 1991 report <br /> contained different and confusing names for the two wells as follows: <br /> PAGE # OR LOCATION NAME <br /> Page 1 "extraction well (XW-8)", <br /> "mon itaring 'we11 (MW-9)" <br /> Page 7 "Monitor well EX-8" <br /> Page 9 ' 11MW-8" <br /> Page 10 and 11 EW-$ MW-9 Wells 8S and 9S <br />
