Proposal for Groundwater Testing <br /> + Preston Pipelines-Delta Water Intake Project <br /> January 12,2010 <br /> Page 3 of 3 <br /> Reporting and Scheduling: Upon completion of field activities, a report documenting the <br /> work will be submitted. The report will include a detailed description of the field activities <br /> and a brief summary of the analytical data. It will be signed by a California Professional <br /> Geologist. <br /> Fieldwork will be scheduled upon your approval of this workplan. Drilling is expected to be <br /> completed in less than one day. The laboratory will generate the analytical reports within 15 <br /> days of the sample submittal, and the report will follow within a week of receiving the <br /> analytical results. <br /> WGR proposes a total project costi�f whict41101fts for the laboratory and soil boring <br /> costs.) Should the WET samples sow` toxicity, it may be desirable to perform a Toxicant <br /> Identification Evaluation (TIE) to identify the cause of the toxicity as was done for the CDM <br /> groundwater investigation of the pipeline portion of this project. The addition of a TIE could <br /> increase the total costs by $3,000 to $10,000 depending on what manipulations are needed by the <br /> toxicity testing laboratory to identify the toxicant. <br /> If you have any questions, please contact Chris Strong, PG, at(209) 334-5363 ext. 206 or me at(209) <br /> 334-5363 ext. 202. <br /> Sincerely, <br /> WGR Southwest,Inc. <br /> 7 <br /> John M.
