groundwater goals. <br /> Based on the results of the 7 March 1994 sampling, SJCPHS/EHD requested a free-product <br /> removal workplan (August 23 1994). Due to the lack of a significant thickness of the FP layer <br /> measured on 7 March and again on 22 July 1994, Dana Booth supplied SJCPHS/EHD with his <br /> professional opinion that the removal of an immiscible layer of the thickness measured at this <br /> site is not reasonably practicable and should be accomplished by the final site remedial system <br /> (9 September 1994). However, on September 15, 1994, SJCPHS/EHD reiterated their desire <br /> for a FP removal action and provided two suggestions for free-product removal. <br /> 1) Bailing <br /> 2) Passive Skimming <br /> This workplan discusses the testing of bailing as the first alternative. If ineffective, this <br /> workplan discusses the implementation of the second alternative. <br /> SCOPE OF WORK <br /> This section describes the work proposed to test the effectiveness of bailing as a free-product <br /> (FP) removal alternative and the implementation of passive skimming if bailing is determined <br /> to be relatively ineffective. <br /> Alternative 1: Bailing Test <br /> On 30 September 1994, the FP thickness will be measured in MW-3. A disposable bailer will <br /> be used to remove the FP and approximately 1 foot of the surface of the groundwater. After <br /> removal of approximately 5 gallons of fluid from the well, the thickness of the FP layer will be <br /> measured. FP thickness will be measured at five (5) minute intervals until the FP layer has <br /> recovered to within measurement limitations (0.01 feet), or for the first hour. If the FP layer <br /> has not recovered in the first hour, the measurement interval will be extended to 15 minutes for <br /> the second hour. If the FP layer has not recovered to within 0.01 feet by the end of the second <br /> hour, bailing will be considered "reasonably effective" and implemented on a quarterly basis (to <br /> coincide with assessment activities). If the FP layer recovers within two hours, bailing will be <br /> considered ineffective and Alternative 2 will be implemented. <br /> Upon completion of this test, the fluid generated will be stored in a DOT approved container <br /> for the transportation of gasoline. The container will immediately be transported to the Ramos <br /> Environmental facility in West Sacramento for recycling. Proper manifesting will be maintained <br /> for proper removal/disposal documentation. The fluid generated from subsequent removal events <br /> will be manifested and recycled in a similar manner. <br /> 3 <br />
