I November 2005 AG;E-NC Project No. 97-0327 Page 3 of 8 detected from P-6 in the 40 foot soil sample at concentrations as high as 0.019 mg/kg. Analytical soil and ground water data is summarized in Tables I and 2. • February 2000 - Ground water monitoring wells MW-1, MW-2 and MW-3 were installed at the site to continue assessment of the lateral and vertical extent of petroleum-impacted soil and ground water; results of the February 2000 investigation were reported in the AGE- prepared Ground Water Monitoring Well Installation Report - I" Quarter 2000, dated 24 April 2000. Laboratory analysis of MW-2 and MW-3 soil samples detected TPH-g at concentration as high as 68 mg/kg, TPH-d as high as 480 mg/kg and BTEX compounds as high as 1.8 mg/kg; and MTBE was detected in MW-1, MW-2 and MW-3 at concentrations as high as 0.89 mg/kg. No other fuel components were detected by laboratory analysis. Analytical soil and ground water data is included in Tables 1 and 2. • November and December 2000 - AGE conducted a sensitive receptor survey to locate potential vertical conduits within a 2,000-foot radius of the site. The results of the sensitive receptor survey did not locate any municipal water wells within 2,000 feet of the site, however, several domestic, irrigation and industrial water wells were located within the 2,000-foot radius. Results of the investigation were reported in the AGE-prepared Sensitive Receptor Survey, dated I 1 January 2 00 1. • January 2002 - Three soil borings (P-10, P-11 and P-12) and one ground water monitoring well (MW-4) were installed at the site to assess the lateral and vertical extent of petroleum- impacted soil and ground water.TPH-d,TPH-g and low BTEX concentrations were detected in the 40-foot soil sample collected from boring P-10,the 45-foot soil sample collected from boring P-I l and the 45-foot and 55-foot soil samples collected at P-12. In addition, MTBE was detected in the 45-foot sample collected from boring P-11.Analytical results of soil and ground water data is included in Tables 1 and 2. Results of the January 2002 investigation were reported in Quarterly Report-First Quarter 2002, dated 17 July 2002, prepared by AGE. 3.0. GROUND WATER MONITORING PROGRAM Between February 2000 and July 2005, fifteen ground water monitoring events were performed at the site to characterize ground water flow direction and gradient,and to monitor dissolved petroleum hydrocarbon concentrations in ground water. Additionally, in accordance with a verbal directive from the SJCEHD,AGE collected water samples from domestic water wells located at 451 and 452 North Lillian Avenue in January 2004 for laboratory analysis; a third domestic well located at 503 North Oro Avenue was reported removed by the property owner.
