Geosyntec consultants 1. INTRODUCTION Geosyntec Consultants, Inc. (Geosyntec) is pleased to present this Limited Phase 11 Environmental Site Assessment (ESA) to Nestle Direct Store Delivery Company (Nestle) to evaluate the Recognized Environmental Conditions (RECs) and historic RECs identified by Geosyntec at the property located at 1351 Dupont Court in Manteca, California (Site; Figure 1). The Limited Phase Il ESA was performed in accordance with our Phase II ESA Work Plan dated 15 November 2013. 2. BACKGROUND The Site is located at 1351 Dupont Court in Manteca, California, in a commercial and light industrial park. The Site is bounded by commercial/industrial facilities to the north (Millard Refrigerated Services and Delicato Family Vineyards distribution center); a railroad then highway rights-of-way to the east; approximately 20 acres of vacant land to the south; and commercial/industrial properties to the west (Geosyntec, 2013a). The Site location is shown in Figure 1. Geosyntec prepared a Phase I ESA for the Site for Nestle in September 2013. The former Spreckels Sugar Plant operated in the vicinity of the Site from 1917 through 1995. The former plant used the Site for the discharge and settling of process wastewater. Ponds associated with the sugar plant wastewater and spent lime were located beneath and immediately surrounding the Site (Geosyntec, 2013a). Closure of the lime ponds began in 1996 and was completed in 2001. During the closure of the ponds, spent lime was removed from the facility and either sold for distribution as an agricultural soil amendment, or it was mixed with native soil and "tare" soil generated during beet washing and redistributed in the vicinity of the sugar plant. The Site was included in the area graded and filled with the lime soil mixture, which occurred in 1999 (Kleinfelder, 2002). Activities associated with the former sugar plant have impacted groundwater at the Site and in the vicinity of the Site, such that concentrations of total dissolved solids (TDS), bicarbonate, chloride, calcium, sodium, and specific conductance were present above background levels in groundwater (Geosyntec, 2013a). Former monitoring well MW- 3R was historically located approximately 1,200 feet north of the Site and was used to monitor groundwater conditions associated with the former Spreckels Sugar Plant through June 2005.
