field activity. Calibration procedures and frequency are listed for each piece. Soil Borimis and Well Dimensions - Steel and coated cloth tape. Calibration: none. Organic Vanors- Photoionization detector. Calibration: Daily logged field calibration using a hexane standard as per manufacturers instructions. All equipment will be checked daily and replaced as necessary. Instrument manuals and an instrument log book will accompany equipment into the field. Any calibration, repairs or related information will be recorded in the log book. 8.0 LABORATORY QA/QC PLAN Groundwater samples will be submitted to a State Certified Hazardous Waste Laboratory for chemical analysis of hazardous constituents. Established QA/QC procedures for analytical operations will include sample custody procedures, standards of analytical accuracy, analysis of matrix spikes and method data, and maintenance of control charts to monitor analytical performance. These QA/QC procedures are outlined in the laboratory QA/QC Plan which is available upon request. Organic chemical analyses will be performed in conformance with standard procedures established by the United States Environmental Protection Agency (EPA) in "Guidelines Establishing Test Procedures for the Analysis of Pollutants Under the Clean Water Act" (40 CFR Part 136, October 1984). The laboratory is periodically evaluated through external performance audits conducted by EPA and DHS using QC labs. The specific analytical methods to be utilized for the groundwater sample analyses are shown on Table 3. 9.0 GROUNDWATER SAMPLING PROTOCOL A proposal will be submitted to the lead Regulatory Authority with proposed boring/sampling locations. The exact location and number of borings at each site will be determined in the field by the Project Geologist/Engineer. Prior to arriving at the sample site, the drill rig/augers will be steam cleaned and all sample equipment will be cleaned. Cleaning will be conducted on-site on all sampling equipment between each sample interval. During sampling, latex gloves will be worn to prevent cross -contamination with other samples. The disposable gloves will be discarded after collecting each sample.
