Baseline data collected were of a definable and documented quality with respect to the precision and accuracy of the measurement (Appendix A, tables 1-12), representativeness of the sampled media, comparability between sites and sampling periods, and completeness of data (Appendix A, tables 2-13). Use of approved EPA or USGS onsite and laboratory methods helped ensure the precision and accuracy of the data. Representativeness of the samples was defined by the number of samples collected at the surface- and ground-water locations. The representativeness of each sample collected was described by the methods used for collection of samples. Detection limits, method detection limits, or reporting limits were used to quantify concentrations in water samples at the levels of at least 20 percent of the currently published MCL for each constituent analyzed except for antimony, beryllium, thallium, 1,2 dibromo-3-chloropropane, heptachlor, heptachlor epoxide, lindane, toxaphene, benzo(a-k)anthenes, bis(2-ethlyhexyl) phthalate, and chrysene (Appendix A, tables 2-13). Antimony and beryllium had reporting levels sufficient to quantify at the level of the MCL. The reporting limits for the organic constituents listed above were greater than the MCL; however, these constituents were not expected to be detected. Reporting limits for constituents without MCLs are listed in (Appendix A, tables 2-13)
