f <br /> samples will then be collected from each well after purging a minimum of three well volumes <br /> (casing and sandpack). The samples will be sent using chain-of-custody record to a State- <br /> certified laboratory analysis of TPHg and BTEX using EPA methods 8015/8020. If other <br /> analyses are required these would be performed at an additional charge. Samples will be <br /> analyzed using standard turn-around-time. Purge water from the wells will be contained on- <br /> site in 55-gallon DOT approved drums pending laboratory analysis. If sample results indicate <br /> non detectable levels of petroleum hydrocarbons, discharge to the ground surface is proposed. <br /> This proposal and cost estimate does not provide for any other purge water disposal. <br /> After laboratory results are received a report will be prepared containing results of the <br /> monitoring and sampling activities. A draft copy will be prepared and submitted to the client <br /> for review. After comments are received a final copy will be prepared for the client and <br /> appropriate regulatory agencies. <br /> All work described in this proposal will be performed under the direction of a California <br /> Registered Geologist or Professional Engineer. <br /> Our total estimated budget for the proposed activities is $14,624. The attached estimated <br /> budget summarizes the cost for the proposed work. Any additional work performed that is not <br /> described in the proposal or estimated budget will be treated as a separate phase of work and <br /> may require a separate proposal and estimated budget. <br /> If the terms of this proposal are acceptable to you, please sign both copies of our attached <br /> Professional Services Agreement and return them to our office for further execution. A copy <br /> of the fully executed agreement will be returned to you for your files. <br /> If you have any questions or need additional information please contact Bill Channell at (209) <br /> 838-3507. <br /> Yours Very Truly, <br /> Canonie Environmental Services Corp. <br /> Bill Channell <br /> Project Manager <br /> BC/gk <br /> Attachments <br /> mAproposaIT90547.doc C,anonleEnvironmental <br />
