�../ 14+11 Environmental Impact Summary Letter Page 5 TEIXEIRA—SOUZA PROPERTY WKA No. 6504.07 Lead Results and Recommendations Based on recommendations made during the inspection of painted surfaces, a total of nine paint samples of suspect material were collected for analysis. The paint samples were collected from five of the single-family residences and from the milking house. Each sample was submitted under chain-of-custody to QuanTEM Laboratories for analysis by atomic absorption spectroscopy in accordance with EPA Method 7420. Lead was detected in one sample collected from a white door on Building 5 at a concentration of 0.061 percent by weight and in one sample collected from a metal hopper located west of the former milking house at a concentration of 0.208 percent by weight. The location and results of these samples is presented on Figure I attached to this Summary Letter. These levels of lead are not defined as lead-based paint by the US EPA or the California Department of Health Services. These two items can be disposed of as non-hazardous waste as long as the paint is not disturbed during demolition activities. To minimize the potential for the paint on these two items to become loose or flaky during demolition activities,their surfaces should be stabilized prior to demolition. Stabilization may consist of scrapping off the deteriorated areas of these structures and placing the removed material in a separate container for disposal as standard construction debris. Destructive testing within the structures was not conducted during the lead survey. All painted surfaces that are not currently visible must be presumed to be lead-based paint until proven otherwise. A detailed report presenting all results and recommendations from the lead survey will be forthcoming. WELL DESTRUCTION There are at let two ater supply wells and one groundwater monitoring well on the subject property that req ' e destruction in accordance with San Joaquin County Environmental Health Department(EHD) requirements. Figure 2 and Figure 3 presents the approximate location of each well. One water supply well is located south of the cluster of residences in a pump house,and one, possibly two,water supply wells are located just north of the former milking barn (Figure 3). The water supply well(s) located just north of the former milking barn may be a nested cluster of two wells possibly constructed in the same borehole based on well head piping and pressure tanks observed during Yield reconnaissance. The monitoring well is located west of the holding corrals along the fringe of the agricultural field (Figure 3). If during dairy demolition activities additional
