�1•3A� <br /> Waste Extraction Test (WET) on soil samples that exhibit total lead concentrations <br /> �reater than �0 mg/kg and less than 1,000 mg/kg. Samples that exhibit soluble lead <br /> (WET) concentrations greater than 5 milligrams per liter (mg/L) will be reanalyzed <br /> for soluble lead via the WET with deionized water used as the extractant (WET-DI). <br /> For the purposes of this Proposal it is estimated that 43 samples will be analyzed for <br /> solublelead. <br /> � Perform QA/QC for each method of analysis with specificity for each analyte listed in <br /> the test method's QA/QC. QA/QC will include the following: <br /> - One method blank for every ten samples, batch of samples or type of matrix, <br /> whichever is more frequent. <br /> - One sample analyzed in duplicate for every ten samples, batch of samples or <br /> type of matrix, whichever is more frequent. <br /> - One spiked sample for every ten samples, batch of samples or type of matrix, <br /> whichever if more frequent, with spike made at ten times the detection limit or at <br /> the analyte level. <br /> d) Report Preparation <br /> A draft report will be prepared to summarize the results of the field activities and <br /> laboratory testing in general conformance with the requirements of Caltrans. The report <br /> will include but not be limited to the following: <br /> • Background summary <br /> • Scope of services performed <br /> • Observations during the field activities <br /> • Results of field activities including laboratory results <br /> • Total and soluble lead statistics <br /> • Site Plan and Vicinity Map indicating boring locations and project boundaries <br /> • Conclusions and recommendations <br /> • Appendices including laboratory reports and chain-of-custody documentation <br /> Upon receipt and incorporation of review comments, four copies of the finalized report <br /> will be provided. If contamination is found at actionable levels, additional coordination <br /> with San Mateo County and/or Regional Water Quality Control Board will be required, <br /> and a Remediation plan may need to be prepared for Caltrans and agency approval. <br /> Additional coordination and investigation effort, including remediation planninj, will be <br /> considered as additional services. <br /> 1.12 Tvpe Seleclion Report <br /> The design of the new ramp bndQe and specialty retainin� walls will be prepared <br /> following the Caltrans Type Selection process.
