TABLE 5-3 <br /> SUMMARY OF SAMPLING PLAN <br /> VADOSE ZONE AND LEACHATE ASSESSMENT <br /> Approximate Sample Number of <br /> Sample Number of Number of Interval Samples per Number of QA/QC <br /> Description Type Borings Sampling De the feet Sampling Depth Duplicate Sam les+ Anal es <br /> Vadose Zone Soil 3 6 10* 1 2 see <br /> Table 5-1+ + + <br /> Background Vadose <br /> Zone Soil 1 6 7** 4 0 see Table 5-1++ <br /> Leachate Soil I 1 N/A 1*** 0 see Table 5-1 <br /> Leachate liquid <br /> (if present) I 1 N/A 1 I see Table 5-2 <br /> + Duplicate soil samples will be collected immediately adjacent to the primary samples. No mixing to homogenize sample will be performed due to the volatile nature of some <br /> analytes. <br /> ++ These samples will be run for the metals listed in Table 5-1. One of the four samples from each depth will also be analyzed for CEC,TOC,pH,and percent saturation. <br /> +++ Six of the soil samples will be tested for physical parameters listed on Table 5-1. <br /> * Sample interval measured along angle of slant boring. <br /> ** Sample interval measured vertically downward. <br /> *** This sample will not be collected if pooled leachate is present. <br /> N/A Not applicable. <br /> C7-90-105 <br />
