All samples will be analyzed for TRPH and total lead. <br /> * Three (3) additional sampling points will be randomly placed on the balance of the <br /> site. Soil samples will be collected at depths of 1 foot and 5 feet. The samples from 1 <br /> foot will be analyzed for TRPH and total lead. The samples collected from 5 feet will <br /> be held by the laboratory pending results of the samples from 1 foot. <br /> * Should lead be detected in any samples at concentrations between 50 and 1000 ppm, <br /> the soluble lead concentration (STLC) will also be determined by analysis. <br /> * We will prepare a report of investigation detailing the methodology and results of the <br /> sampling and proposing additional investigation and!or remediation as appropriate. <br />
