Mr. Cecchini <br /> June 28, 1993 <br /> Page 3 , <br /> Single distilled water (retail grade) was used in error for the trip blank. This water is likely <br /> not free of the analytes reported. In the future, triple distilled, (laboratory grade) water will <br /> be used for trip blanks. <br /> Interim (Remediation <br /> As a result of the continued detectable TGIF in well UST-1, interim remediation was <br /> initiated for this site. Mr. Robert Cecchini will perform weekly evacuation of water from <br /> Well UST-1 for a period of three months (third quarter 1293). He will perform the <br /> following tasks: <br /> Measure water and product levels in the well using an electric water level sounder <br /> and a clear bailer. This information will be recorded. <br /> G Evacuate 30 to 50 gallons of water from well UST-1 using an electric submersible <br /> pump. If the well should become dry during the purging process, then we will <br /> evacuate the well dry a total of three times. The volume of water pumped from the <br /> well will be recorded. <br /> The water evacuated from the well will be stored in DOT rated drums in a secure � <br /> area of the site. <br /> Dispose of all water stored in drums within 90 days of placement in the drum. <br /> Results of the well evacuation will be documented in the third quarter 1993 <br /> monitoring report to be prepared by ESE. <br /> On behalf of the Cecchini, Cecchini & Glovannom, in a letter to the County dated June 3, <br /> 1993, ESE requested that the purge water be treated through the truck wash system at the <br /> site This request is currently pending approval within the ext month according to Mr. <br /> Infurna of the County <br />
