"It is difficult to know how many locations should be sampled when looking for contaminants at uncontrolled waste disposal sites. This is especially true at large sites which may have been subject to small releases of unknown chemicals at indefinite locations. A method was presented to estimate the minimum number of samples required to reasonably assure detection of the smallest contaminated area that may present an unacceptable impact to human health. The approach was applied to a 50 acre former municipal and industrial waste site. Multiple contaminants having varying degrees of toxicity were considered. The results suggested using both composite and discrete samples to independently represent 16 areas of concern AOCs. Using both methods provided a redundancy which yielded two separate estimates of |
