Soil samples were tested for a broad spectrum of chemical parameters. The complete list of the pesticides for which tests were conducted is included in Appendix A. Laboratory Test Results and Chain-of-Custody Forms, J Sample boring locations are shown on Figure 3. Sampling intervals are given in feet, and based on depth below ground surface (bgs). J Pesticide analytical results and detection limits are given in ug/kg (ppb). Nitrogen results are given in mg/kg (ppm). ND signifies a parameter that has not be detected. NE signifies a maximum contaminant level (MCL) that has not been established. J Nitrate results were converted to nitrogen-as-nitrate results (N-NO,)by multiplying each reported nitrate result by 0.225, the stoichiometric conversion factor for the nitrate ion.
