QUALITY ASSURANCE AND QUALITY CONTROL PLAN <br />The Remedial Investigation (RI) Quality Assurance/Quality Control (QA/QC) program is intended <br />to facilitate the acquisition of accurate and reliable data. Environmental data gathered during the RI <br />will be collected and analyzed following procedures prescribed in the Quality Control Program. A <br />Quality Assurance Program has been established to assure that the Quality Control Program is <br />effective. Both programs are necessary to provide accurate data and documentation for <br />investigations and laboratory analyses. The following field and laboratory procedures will be <br />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 boolddaily 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. P1D 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 />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:\Data\GROUNDZE\GOEMAN ACAMPO \REPORTS \QAQC.doc
