3.0 PROCEDURES <br /> i <br /> 3.1 Monitoring Well Sampling <br />' On March 4, 1994, the water levels in each well (except MW-2) were measured relative to <br /> the top of the casing using a Solinst water level meter (Table 1). <br />' TABLE 1 <br /> RELATIVE GROUNDWATER ELEVATIONS <br />' Depth to Groundwater Relative Groundwater <br /> Relative Elevation <br /> Well No. Casing 10/93 3/94 10/93 3/94 <br />' Elevation <br /> ' MW-1 98.16 60.47 57.07 37.69 41.09 <br /> MW-3 97.32 ____ 56.80 40.52 <br /> MW-4 98.30 60.75 57.14 37.55 41.16 <br /> MW-5 96.78 59.54 56.03 37.24 40.75 <br /> MW-6 97.60 59.81 56.30 37.79 41.30 <br /> MW-7 98.11 60.57 57.16 37.54 40.95 <br /> MW-8 97.94 60.27 56.77 37.67 41.17 <br /> "All measurements in feet <br /> After water Ievels were measured, a clean PVC bailer was used to surge and purge each <br /> ' well. Approximately 5 to 8 gallons of water were removed from wells MW-4 through MW-8 <br /> to stabilize temperature, pH and conductivity (Table 2). Due to poor recharge, only 9 <br /> gallons were removed from MW-1 and less than 1 gallon was removed from MW-3. The <br /> purge water was stored in 55-gallon drums on-site. Field data sheets are included in <br /> ' Appendix B. <br /> ' Water samples were collected from MW-1 and MW-4 through MW-8 using a new disposable <br /> plastic bailer. The samples were collected in 40-m1 EPA vials. MW-3 did not recharge, and <br /> therefore no sample was collected. <br /> 3.2 Laboratory Y p Analysis of Water Samples <br /> The water samples were placed in a chilled container and transported under chain-of- <br /> custody to Alpha Analytical Laboratory (AAL) in Ukiah, California.
