Box 757 <br /> Ripon, CA 95366 <br /> Dear Dennis : <br /> SUBJECT: PROPOSAL FOR SERVICES - BURIED TANK SOIL INVESTIGATION <br /> This letter is a work outline for soil sampling and testing of <br /> samples from two buried-tank sites at your Ripon facility. <br /> The scope of work is in response to your letter of June 6 , 1988 <br /> to Jaime Favila of the San Joaquin Local Health District, and to <br /> Favila ' s memorandum to you dated May 24, 1988. <br /> It would be our intent to sample the two sites at the end of our <br /> work installing the ground-water monitoring wells. Our estimate <br /> of when we will do the soil sampling is towards the end of this <br /> month. <br /> Because the tanks were only about 3 to 4 feet in diameter, <br /> samples will be taken at about 6 feet. It is only proposed to <br /> take one sample at each site, although if there is any indication <br /> by smell or sight that leakage has occurred we will take <br /> additional samples at greater depth. <br /> Samples will be taken by a split-spoon sampler through a hollow- <br /> stem auger. After retrieval , samples will immediately be <br /> transferred to air-tight jars. <br /> Samples will be sent to a certified laboratory and the following <br /> tests will be conducted: <br /> Site 1 - BTX, TPHC, Lead, EDB, and tetraethyl lead <br /> Site 2 - BTX, TPHC, Chlorinated solvents, PCB <br /> Very truly yours, <br /> David A.
