Our comments are as <br /> follows : <br /> REVIEW OF PRELIMINARY REPORT DATED JANUARY 3, 1989 : <br /> We have reviewed the 3 January 198 Preliminary Report for this <br /> site and find it to be incomplete. Addit-ional site information <br /> and investigative work is needed tD complete this site <br /> assessment. <br /> 1. Each report is to contain inf rmation from previous reports, <br /> as necessary and available, t3 assure that it may be <br /> reviewed independently. It ii not acceptable to reference a <br /> graph, table, boring log, or Cher references, in another <br /> report. Copies of the Canoni Environmental Services <br /> Laboratory Report No. 85-052-3580 and No. 85-052--3776 for <br /> samples collected in the tank pit on 11 February and 14 <br /> March 1988, respectively, were not included within this <br /> report. <br /> 2. A site map indicating the sam le locations for each sample <br /> collected from the tank pit oi 11 February and 14 March 1988 <br /> should be submitted. <br /> 3. Th-e location of each tank lab led by contents should be <br /> shown on a site map. <br /> 4. Field techniques are good sc eening mechanisms, but <br /> quantitative analytical resul s are recommended to support <br /> "zero-line" definition. <br /> 5. First encountered groundwater should have been noted on <br /> boring logs, using unified classification symbol found on <br /> Plate P-3 of this report (enclosed) . <br /> 6. Water measurements should be reported in "ppb" not "ppm". <br /> Contaminants such as Benzene could accidentally be reported <br /> as "ND". see sample # W-27-MIJI of Analysis report <br /> (enclosed) . <br /> A Division of San Joaquin County Health Care Services <br />
