Proiect Number 2098RV45 November 30 2017 <br /> 4.8.6 Analytical Methods <br /> All VOC samples will be analyzed using only a Gas Chromatograph/Mass <br /> Spectrometer (GC/MS) by EPA Method TO-15, or equivalent. <br /> 4.8.7 Target Compounds <br /> The ASGI (CA EPA July 2015) includes twenty-three (23) primary and four (4) other <br /> target VOCs. All quantifiable results will be reported. The estimated results of all <br /> Tentatively Identified Compounds (TICs), or non-AGSI-targeted compounds detected, <br /> will be included in the status reports. If TICs, or non-ASGI targeted compounds are <br /> identified, EzC will consult with the CRWQCB to determine whether additional action <br /> is required (e.g., running additional standards to quantify TICs, or non-ASGI <br /> compounds) and whether the use of these estimated data for risk evaluation is <br /> appropriate. All quantifiable results of Leak Check Compounds will be reported as <br /> specified in above. <br /> 4.9 Soil-Gas Investigation Reports <br /> Soil-gas monitoring data, including a discussion of field operations, deviations from <br /> the approved Workplan, data inconsistencies, and other significant operational details <br /> will be documented in the report of findings. The report of findings will contain soil- <br /> gas isoconcentration plots for constituents of concern (COCs) at a scale of 1 inch = 30 <br /> feet and summary tables for analytical data [in micrograms per liter (µg/L)], in <br /> accordance with the Active Soil Gas Investigation (ASGI) guidance (CAL EPA, July <br /> 2015). EzC will also provide legible copies of field and laboratory notes or logs, all <br /> analytical results and Quality Assurance/Quality Control (QA/QC) information, <br /> including tables and explanations of procedures, results, corrective actions and effect <br /> on the data. <br /> E2C Remediation 15 <br />
