z information as well as upgradient and downgradient water quality information fr-on the first encountered groundwater system. Additionally, information was collected on the lithology present at the site from the soil samples and borehole cuttings. The following section summarizes the field work. Appendix A presents a. Field Report containing detailed information. 3 . 1 Field Work. summary Soil. borings included the collection of soil samples at 1, 3 and 5 foot depths at each location. The boring locations are shown on Figure 2 . The soil samples collected were labeled with a borehole number and depth combination for identification purposes ( i . e. , BA-1. = sample from borehole BA collected at a depth of 1 ' ) In addition, records of soil. textures/1ithologies were �. maintained and are presented in Appendix A. All boreholes were drilled with a power auger but sampled at each appropriate depth with a hand auger. These soil samples were submitted to the WESTON Analytics' Stockton, California laboratory for analysis. Groundwater monitoring wells were spaced around the operations area in a triangular configuration (Figure 2) . Each well was screened 2 to 3 feet into saturated soils, with the sand pack extending an additional 1.5 feet or more above the water table to allow for variations in water levels during any subsequent sampling_ A well construction summary is provided in Table 1.

The following procedures were performed at each well: 1) measurement of depth to water and total depth of- well , 2) pijrgi.ng of at least 3 standing well volumes by bailing or bailing the well dry 3 or more times, and 3) bailing sufficient water for sampling from the well . Although the shallow monitoring wells were screened at least 2 feet into the uppermost unconfined aquifer, only M13 (see Figure 2) yielded enough water to be purged and sampled on the same day. The monitoring wells MW1 and MW2 were bailed dry after removal of only a few .liters of water. Recovery was very slow and the water 3 -
