NVA001 -./ The test well will be constructed with 8-inch diameter casing to a depth of approximately 180 feet with approximately 20 feet of screen and a 15-foot sump. Other design features of the well will include a 100-foot annular seal. The final design of the test well will be based on conditions encountered in the field. The borehole for the well will be completed using the mud rotary drilling method. Cuttings generated during drilling will be described and logged under the supervision of a professional geologist. Cuttings generated during drilling will be spread on Kruger Foods and SMS Briners property. Fluids will be contained and will be allowed to evaporate with the residual solids mixed with the cuttings. The well will be developed by simultaneous airlift pumping and swabbing. Airlift development operations will be performed with a check valve to preclude the introduction of air into the gravel pack. Any fines developed will be removed with a bailer. The wellhead will be completed with a concrete pad installed to protect the wellhead and to control surface drainage. Following development, the well will be surveyed to accurately locate the well and to determine wellhead reference elevations. Baseline sampling of EW 1 will be conducted following well development to establish baseline groundwater quality conditions. Groundwater samples will be analyzed for constituents listed on Table I of the Groundwater Monitoring Program of the Monitoring and Reporting Program No. R5-2004-0157. In addition, 1,2-dibromocloropropane(DBCP)will also be added to the list of constituents to be analyzed. Prior to sampling the well,purging will be conducted and electrical conductivity, turbidity, temperature, and pH will be monitored. 5.4 Shallow Zone Aquifer Characteristics An aquifer test in the shallow zone has not been performed at the SMS Briners facility to date and current estimates for transmissivity in the shallow zone were derived from estimates of specific capacity at MW3A. As a result of implementing an expansion of the existing groundwater remediation system, a more accurate determination of shallow zone aquifer characteristics is needed to refine the capture zone analysis and to ensure that remediation of salt-impacted groundwater is optimized. A constant rate aquifer test of the shallow zone is planned for a pumping duration ranging from 12 to 24 hours. The pumped well, EWl, will have a constant discharge rate determined via a pre-test but would likely range between 20 to 30 gallons per minute(gpm). The r duration of the test will in part be determined based on evaluation of the data as the test is being conducted. Recovery data will also be recorded following the test for a two-hour or longer period. Drawdown and recovery measurements (along with discharge data)will be collected from the pumped well using electronic pressure transducers along with measurements of water levels from adjacent shallow and deep monitoring wells, with particular attention to monitoring wells MW 1 and MW3A.
