I991 <br /> Post Office Box 5011 <br /> Richmond, California 94805 Reference: M88168G <br /> Attention: Mr. Harrison Peddie <br /> President <br /> Subject: Ground Water Monitoring and 8ydrogeology, Color Spot Facility, 5408 <br /> East Harney Laoe, Lodi, California. <br /> Dear Mr. Peddie: <br /> This letter-report presents the results (documented in Appendix A ^ <br /> Laboratory Analytical Results) of the laboratory analysis of ground water <br /> collected from monitoring well MW`l at the subject facility (see Figure l ` Site <br /> Location Map) . This letter-report also includes data regarding nearby water <br /> wells and presents our conclusions and recommendations regarding the need for <br /> additional site assessment and remediation. <br /> The most recent letter from the County of Sao Joaquin Public Health <br /> 3ernices, Environmental Health Division (C8D) to Color Spot, Inc. regarding the <br /> site assessment related to the subject OSI was received on February 26, 1991. <br /> The letter stated that more data would be required to consider site closure. To <br /> that end, 3GD collected the ground water sample from MJ-1 for analysis and <br /> collected the well data presented here. In the letter (included in Appendix <br /> 8 ^ Correspondence) it is apparent that E8Dwas referring to less current ground <br /> water data than are reported here. It is also apparent that drawdown of the <br /> water cable from nearby pumping well(s) was not considered. <br /> SAMPLE COLLECTION AND ANALYSIS <br /> �/ <br /> Monitoring well No. MW~l is located approximately I00 feet to the ~'� <br /> north of the former location ofa4,0Q0`galluo capacity underground storage caob <br /> (OST) used to score diesel fuel (see Figure 2 ' Site Plan) . The tank removal was <br /> observed and documented by Staal, Gardner & Dunne, Inc. (SQD) on March l, 1989. <br /> The tank removal, so8segaeoc site assessment, and mitigation measures have been <br /> documented by SGD in the following reports: <br /> w <br /> Underizround Storave Tank Removal.
