Ph <br /> F �S3`7�boZ <br /> August 18, 1999 <br /> Mr. Jeff Wong <br /> San Joaquin County <br /> Public Health Services-Environmental Health Division <br /> 304 East Weber Avenue, 3rd Floor <br /> Stockton, California 95202 <br /> Subject: Valley Showcase <br /> 901-921 West Fremont Street <br /> Stockton, California <br /> Dear Mr. Wong: <br /> As you know, we are planning to carry out the scope of work detailed in our Workplan for <br /> Ground-Water Monitoring Well Installation and Continued Quarterly Ground-Water Sampling. <br /> on Friday, September 3, 1999, Today, we received your faxed approval of our well permit. <br /> Upon a review of our files, we realized that your May 26, 1999 letter indicated that you no <br /> longer require us to analyze our soil and ground-water samples for petroleum oxygenates. <br /> Although our workplan had mistakenly stated that we would, we will instead follow your earlier <br /> directive and not perform petroleum oxygenate analyses. In addition, we assume that you <br /> will be on-site during drilling activities to Identify those soil samples that you wish to have <br /> analyzed. With regard to field equipment, and as you requested, we have no problem with <br /> using real crushed ice in our sample coolers. We also will be using a MiniRAE portable <br /> photoionization detector to screen samples and ambient air. <br /> Please don't hesitate to contact us with any questions. <br /> Respectfully, <br /> JJW GEOSCIENCES Inc. <br /> Timothy L. Karpin, CHMM,CPG <br /> Project Manager <br /> cc: Mr. Luis Lechich -Valley Showcase <br /> tlk:Wongltl.doc <br /> 11360 Monier Park Place, Rancho Cordova,CA 95742 Tel: 918.853.8025 Fax: 918.853.8029 <br />
