level & amount of free product, if any, will be measured by use <br /> of a electrical multiphase interface probe device After <br /> determining the effective depth, each well will be purged by <br /> evacuating a minimums of three ( 3) casing volumes of fluid from <br /> the well. Purging may be accomplished by either (1 ) bailing by <br /> use of a disposal teflon or reuseable stainless steel bailer; (2) <br /> pumping by use of a downhole impeller or bladder pump, or ( 3) a <br /> surface peristatic pump. All equipment will be thoroughly <br /> decontaminated with Alconox & clean water, with a final rinse <br /> with deionzzed or distilled water prior to use <br /> 15. During purging operations, the water will be continually <br /> monitored to determine temperature, pH, & electrical conduct- <br /> ivity. After the reading indicate that well conditions have <br /> stabilized, water samples will be collected by use of a clean <br /> teflon bailer run on new nylon cord. They will be placed in <br /> clean glass vials & sealed with teflon lined lids making sure <br /> there is no headspace. The samples will be promptly preserved on <br /> ice & transported to a State Certified laboratory under proper <br /> chain of custody. Samples are to be analyzed for BTEX (EPA 602, ) <br /> TPH-G (EPA 5O3O/8O15M, ) and TRPH, (EPA 351O/8O15M ) Persone.l from <br /> the responsible regulatory agency will be contacted prior to <br /> start of purging & sampling operations <br /> 16. The wellhead elevation & surface coordinates will be <br /> determined by a licensed surveyor after well has been completed <br /> After completion of the above work, receipt & analysis of all <br /> field notes & laboratory reports , a report will be prepared and <br /> submitted to the responsible agencies _ <br /> If you have ny questions concerning this proposed workplan, <br /> plea, ef on t our office at your earliest convenience. <br /> W <br /> Wm J_ anter & Associates <br /> cc- da Turkatte, San Joaquin Co EHD <br /> W Milds <br /> W Nolet <br /> J.
