Drums will be appropriately labeled, and within 60 <br /> days following receipt of all waste analytical data, a request for disposal will be submitted to <br /> an appropriate landfill or other disposal facility in accordance with the waste classification. <br /> Within two weeks following receipt of written authorization of waste acceptance, all <br /> investigation-derived waste will be transported to the appropriate off-site disposal facility by <br /> a transporter meeting all certification and licensing requirements of the State of California. <br /> 2.5 Boring Locations and Surveying <br /> Upon completion of the proposed borings and monitoring wells, geographic locations will be <br /> recorded using a measuring tape with respect to fixed locations. A licensed surveyor will <br /> survey boring and well locations horizontally with the California State Plane coordinates. <br /> Vertical coordinates for the monitoring wells will be established to the nearest 0.01 foot with <br /> respect to the USGS datum. Additional site landmarks will also be surveyed. <br /> 1 <br /> 3.0 ENVIRONMENTAL SAMPLING <br /> This section contains a discussion of the program planned for collecting samples for <br /> chemical analysis—including regulatory requirements, sample collection procedures, and the <br /> procedures to be followed to maintain sample integrity. Photographs will be taken to <br /> document all sampling locations. <br /> 3.1 Direct-Push Groundwater Sampling <br /> Groundwater grab samples will be collected from the direct-push reconnaissance borings at <br /> the soil/groundwater interface, at approximately 20 feet bgs. Groundwater samples will be <br /> collected using a peristaltic pump or dedicated disposable bailer, and placed in laboratory <br /> supplied bottles and labeled. Field analysis will be conducted for electrical conductivity <br /> ("EC"). Prior to EC analysis, samples will be allowed to sit until the sediment has settled <br /> and the samples are relatively sediment free. Groundwater samples from the reconnaissance <br /> borings will be submitted to a state-certified analytical for additional analysis. Prior to <br /> testing,the laboratory will filter the samples using a 0.45 micron filter to remove any soil <br /> particles that might result in elevated constituent concentrations. <br /> No chemical analysis of soil samples is proposed,unless evidence of off-Site soil <br /> 1 contamination is encountered. The reconnaissance groundwater samples will be analyzed for <br /> William DePaoli Property 6 of 15 <br /> Sampling and Analysis Plan <br /> June 2009 <br />
