a , 15 June 2005 AGE-NC Project No. 03 - 1070 Page 4 of 7 as a remedial alternative at the site. A constant ground water pumping rate for the 24-hour aquifer pumping test will be based on the results of the 8-hour pumping test and the availability of storage for the produced water. If it appears that steady state conditions have not been achieved at the end of the 24-hoar test, the test period will be increased to 48-hours. The pumping test may required up to 72-hours because of the slow percolation of water the stratified deposit commonly found in the Central Valley alluvial soils. In no event should the aquifertest be terminated prior to aquifer stabilization, because the limited datamay not exhibit the nature of the aquifer. During the 8-hour pump test, grab ground water samples will be taken from the effluent line during selected portions of the pump-test; approximately every two hours. The ground water samples will be collected into laboratory-supplied 40-milliliter (ml) volatile organic analysis (VOA) vials containing 0.5 ml of hydrochloric acid as preservative. Care will be taken to ensure that visible air bubbles are not present in the vials after filling and capping. Following collection the samples will be appropriately labeled, placed on ice and kept in a cooler until delivered to a DHS-certified analytical laboratory for analysis. Chain of custody (COC) protocols will be used to document sample custody transfer from the field to the laboratory; a COC form will accompany the samples. All pumping test procedures are described in Section 4.4. , 3 . 5 , PREPARATION OF REPORT OF FINDINGS Following completion of the proposed scope of work a report will be prepared presenting the findings. The report will include a description of work performed and the results of 1 ) soil sampling and analysis and 2) the pumping test. Conclusions and recommendations will also be included in the reports, if applicable. The report will be in a format acceptable to the E14D and the California Regional Water Qualaity Control Board (RWQCB), and will be reviewed and signed by a California Professional Geologist. 4.0. FIELD PROCEDURES All field procedures will be overseen by an AGE representative under the supervision of a California Registered Geologist. Procedures for well installation, development and ground water feasibility pilot testing procedures are described below. Advanced GCOEnvironmental, Inc.
