QUALITY ASSURANCE AND QUALITY CONTROL PLAN <br /> The Remedial Investigation (RI) Quality Assurance/Quality Control (QA/QC) program is <br /> intended to facilitate the acquisition of accurate and reliable data. Environmental data gathered <br /> during the RI will be collected and analyzed following procedures prescribed in the Quality <br /> Control Program. A Quality Assurance Program has been established to assure that the Quality <br /> Control Program is effective. Both programs are necessary to provide accurate data and <br /> documentation for investigations and laboratory analyses. The following field and laboratory <br /> procedures will be implemented to ensure that QA/QC objectives are met. <br /> 1.0 RECORDING OF FIELD DATA <br /> All information pertinent to the field investigation will be kept in a field log book/daily log. <br /> Information to be documented includes at least the following: <br /> - Sample numbers <br /> - Locations of sample collection <br /> - Soil boring or well numbers, as applicable <br /> - Depths at which samples were obtained <br /> - Names of collectors <br /> - Dates and times of collection <br /> - Purpose of sample <br /> - Sample distribution (e.g. laboratory, archive, etc.) <br /> - Field observations <br /> - Field measurements (e.g. PID readings, pH, conductivity, water levels.) <br /> - Other data records (e.g. development log, soil sampling report, well log, etc.) <br /> 2.0 SAMPLE CONTAINERS <br /> Groundwater samples will be placed in containers supplied by the analytical laboratory. Table 1 <br /> PP Y rY <br /> summarizes the required sample containers. Soil samples will be collected in either 8-ounce <br /> widemouth clear glass jars provided by the laboratory or in clean brass or stainless steel tubes <br /> (Table 1). Screw on caps will be fitted with Teflon liners. Tubes will tightly capped and sealed. <br /> G:\GROUNDZE\QAQC\QAQC.doc <br />
