Combustible Gas Oxygen- Combustible gas/oxygen meter <br /> calibration: Factory calibrated, field calibrated monthly, <br /> . zeroed daily according to manufacturers instructions. <br /> Aiscallaneous Measuring Devices Calibration procedures for <br /> any other measuring device used will be documented at the <br /> request of the regulatory authority. <br /> All equipment will be checked daily and replaced as <br /> F, necessary. Instrument manuals and an instrument log book <br /> will accompany equipment into the field Any calibration, <br /> repairs or related information will be recorded ire the log <br /> book. <br /> 8.0 Laboratory QA/QC Plan <br /> Soil and groundwater samples will be submitted to a State <br /> Certified Hazardous Waste Laboratory for chemical analysis <br /> of hazardous constituents. Established QA/QC procedures for <br /> analytical operations will include sample custody <br /> procedures, standards of analytical accuracy, analysis of <br /> matrix spikes and method blanks, data reduction, <br /> verification of .raw analytical data, ane maintenance of <br /> *� control charts to monitor analytical performance. These <br /> QA/QC procedures are outlined in the laboratory QA/QC Plan <br /> which is available upon request. Organic chemical analyses <br /> E will be performed in conformance with standard procedures <br /> established by the United States Environmental Protection <br /> Agency (EPA) in "Guidelines Establishing Test Procedures for <br /> the Analysis of Pollutants Under the Clean Water Act" (40 <br /> CFR Part 136, October 1984). Tha laburatc.:y is <br /> p-riodically evaluated through external performance audits <br /> conducted by EPA and AHS using QC labs. The specific <br /> . , analytical methods to be utilized for purgeable and <br /> semivolatile hydrocarbons analyses are shown on Table 2. <br /> Provided the data base is of sufficient size, btat:istical <br /> techniques may be employed for data validation. <br /> 9.0 Groundwater Monitoring Protocol <br /> Monitoring of depth to water and free product thickness <br /> within wells at the site will be conducted using an <br /> Interface Probe or conductivity meter. For consistency, all <br /> measurements will be tarsen fro.a the north side of the <br /> wellhead at the survey mark. To assess potential <br /> infiltration of fine grainer sediments, total well depth <br /> will also be sounded. <br /> r <br /> F <br /> I <br /> oa <br /> i <br />
