Project No 014-95262 Page No 4 subject property Comparison of the two elevations indicates that groundwater in the vicinity of the project site would be approximately 27 feet below existing grade According to subsurface investigative reports reviewed for the project site, groundwater was reported to be approximately 30 feet below grade as of June 1994 On-site monitoring well MW-5 was sounded at the start of field activities (September 21, 1995), the depth to groundwater was noted to be approximately 24 5 feet below ground surface at that time The WCD map also indicates that the lateral component of groundwater flow is generally in a east- northeast direction in the vicinity of the subject site Review of the WCD maps from previous years indicate that groundwater flow direction has remained essentially unchanged during recent years The most recent groundwater elevation data from on-site monitoring wells also suggests an easterly flow direction However, numerous factors influence the fluctuation of groundwater level and evaluation of such factors a is beyond the scope of this investigation 6.0 PURPOSE, SCOPE AND METHODOLOGIES OF THE INVESTIGATION The purpose of the our proposed services was to assess the presence and concentration of certain constituents in soil and/or groundwater beneath the site as it relates to the former military use and, more recently, to meat processing and associated wastewater treatment activities at the subject site The investigation was conducted for real estate transaction due diligence purposes, and was not conducted to meet the requirements of any regulatory agency A site inspection was conducted on September 1, 1995 as part of Krazan's Phase I Environmental Site Assessment of the Safeway site During the site inspection and aerial photograph review, certain areas were targeted for further investigation These areas included the brine tank vicinity, the wastewater treatment plant and pond, the former military service buildings, the former boiler fuel supply line, and areas used for stockpiling and disposal of UST excavation spoils MThe investigation included the collection of nine Hydropunch'II groundwater samples obtained by direct push methods using a cone penetration testing (CPT) rig At six of these locations, CPT soundings were conducted to determine favorable zones (sandy units) for groundwater sample collection The purpose of these groundwater samples was to assess the presence and distribution of certain constituents of concern resulting from both aerially extensive and local point sources At three of the Hydropunch' and at three other locations, soil borings were advanced to the capillary zone by an auger drilling rig to collect soil samples for analysis In addition, 12 hand auger borings were advanced at selected locations to sample soils in the vicinity of sumps, separators, etc , adjacent to the former boiler i KRAZAN& ASSOCIATES, INC Offices Serv7ng the Western United States 95262 Ps2
