摘要

任何土壤污染整治改善實施後均需要驗證是否達成既定目標，本文提供一個分析方法來評估改善之成效。由於驗證樣品畢竟僅代表整個整治改善區非常小的一部分，在這種具有不確定之情況下所作之結論，實有必要將統計策略用於驗證方案之中。統計方法有一個強大的功能，按科學的推論有效的將採樣結果量化，可解釋整個改善場址之狀況並驗證其成效。本文建議之驗證準則包含四個部分，第一：任何一個驗證樣本之濃度均需低於管制標準值，第二：採樣結果之累積機率97.5%對應之濃度值需低於管制標準值，第三：採樣結果之累積機率50%對應之濃度值需低於監測標準值，第四：改善整治工程之均勻度指標值需小於2。

This paper provides analysis methods for evaluation whether a soils remediation effort had been successful. Statistical methods are emphasized because there is a practical need to make decisions regarding whether a site has met a cleanup standard in spite of uncertainty. The uncertainty arises because only a small portion of the soil at the site are being able to sample and analyze yet having to make a decision regarding the entire site. Statistical methods are designed to permit this extrapolation from the results of a few samples to a statement regarding the entire site. The suggested guideline provides a technical interpretation of what data analysis methods are acceptable for verifying attainment of a cleanup standard in soils media.
The guideline includes four parts. The first component is the concentration of every sample should less than the control standard. The second component is the 97.5% probability of cumulative curve should not exceeds the control standard. The third component of the standard is the median concentration of sampling should below the monitoring standard. The fourth component is the indicator of evenness for the remedy works should less than 2.
