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. _. i Field Work Summary Sni,l. borings i.n.cluded the collection of soilsamples at 1, 3 and 5 root depths at each location.

C.rrc:)undwater monitoring wells were spaced around the operations area in a triangular co.n.ffiguration (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 al.low for variations in water levels during any subsequent sampling_ A well construction summary is provided in Table 1.
