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 />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 sample 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 />Storm drain water samples will be placed in the appropriate containers supplied by the analytical <br />laboratory. Table 1 summarizes the required sample containers. Soil samples will be collected <br />in acetate tubes (Table 1). The ends of the tubes will be covered with a Teflon® sheet and <br />tightly capped and sealed. All sample containers will be uniquely labeled for identification. All <br />samples will be placed on ice pending delivery to a State -Certified Laboratory. <br />G:\GROUNDZE\LIONUDAKIS\Workplan\QAQC.doc <br />
