(Apex), is pleased to provide Moore Petroleum (Moore) this report documenting the results of the limited subsurface investigation conducted at the subject site (Figures I and 2) and results of the fourth quarter groundwater monitoring conducted on October 28, 1999. The subsurface investigation included the drilling of four soil borings with soil sampling, converting three of the four soil borings into 2-inch-diameter groundwater monitoring wells MW-4A, MW-7, MW-9, and converting the fourth soil boring (MW-8) into a 4-inch diameter well. The purpose of the subsurface investigation was to determine the distribution, if any, of petroleum hydrocarbons in soil and groundwater beneath the site. The monitoring included collection of depth-to-water measurements and groundwater samples from all existing monitoring wells MW-l; MW-2, MW-3, MW-4A, MW-5 through MW-9 (Figure 2). This report is based, in part, on information obtained from Moore Petroleum, and is subject to modification as newly acquired information may warrant. BACKGROUND Apex began work on this project with the groundwater monitoring conducted on January 14, 1994.
