19 November 2009 AGE-NC Project No. 02-0950 Page 7 of 13 On 10 April 2004, an AGE representative reviewed well driller's reports from the California Department of Water Resources —Central District for water wells located in the surrounding area. Driller's reports for 14 water wells located within a 2000-ft radius of the site were identified. On 01 December 2004, Mr. Rodney Estrada of EHD was contacted by an AGE representative for records of septic systems or permits for wells located on the site property.No septic system or well permits were located for the subject property. On 30 November 2004, an AGE representative performed a field reconnaissance for visually observable potential sensitive receptors located within a 2,000-foot radius of the subject site. No additional water wells were identified during the reconnaissance. On 01 December 2004, Mr. Eric Mar of California Water Service was contacted by an AGE representative.According to Mr.Mar,drinking water in the area of the site is currently supplied and maintained by California Water Service. However, service to the subject site is currently inactive (turned off).In addition,Mr.Mar confirmed that there are no municipal wells in the area surrounding the site. On 01 December 2004, Mr. Richard Stiffler of City of Stockton Municipal Utilities District, was contacted by an AGE representative. According to Mr. Stiffler the sewer system in the site area is maintained by the City of Stockton. Several monitoring wells are located within a 2,000-foot radius of the subject property. However, because monitoring wells are not utilized for drinking water purposes, and are destroyed upon completion of the respective investigations, it is unlikely that:they represent true "receptors" for contaminated ground water associated with the Masonite facility. No additional wells were located within 2,000 feet of the subject property on the DWR database;no additional wells were identified during the physical survey. Copies of the well driller's reports are included in Appendix G.A summary of water wells located from the review of well driller's reports is included in Table 7, and the location of wells are depicted in Figure 9. 4.0. SOIL CORRECTIVE ACTION Between 09 and 10 July 2007,petroleum hydrocarbon-impacted soil was excavated at the site by L &B Environmental Inc. (L&B)of Stockton,California. Soil was excavated around the former UST area encompassing an area 20 feet by 30 feet,and to a depth of 25 feet bsg.Approximately 506 cubic yards of soil was excavated as part of corrective action for this site. Based on field observations (organic vapor meter readings, stained soil, hydrocarbon odors), impacted soil was encountered at Advanced GeoEnvironmental,Inc.
