本計畫目的係針對彰化縣新圳、小新圳灌區及環保局指定改善之污染農地進行土壤細密調查工作，建立每筆農地之土壤污染濃度分佈資料，規劃以耕犁工法為主要工法，其可搭配局部排客土法進行污染改善，將污染農地解除列管還地於民，另一方面，需釐清無法於本計畫施作以大量排客土法進行污染改善之農地，擬定合適之排土範圍及數量，供後續農地改善計畫參考之依據。本計畫執行成果依契約工作項目分述如下： 1.補充調查：共計完成37.17公頃農地細密調查作業。 2.地籍鑑界：共計完成0筆地籍鑑界。 3.污染改善作業：共計完成約22.21公頃農地污染改善作業，其中，以耕犁工法完成21.09公頃；以耕犁工法搭配局部排客土法完成1.12公頃。 4.排客土檢測：共計完成4筆坵塊排土土方TCLP檢測及客土土方重金屬篩測工作。 5.排客土工程：共計完成482.95公噸排土處理工作、客土購置及清運等。 6.自行驗證作業：共計完成22.21公頃自行驗證採樣及檢測等工作。 7.農民地主說明會：共計完成3場次說明會。

The project goal is to conduct the soil investigation on heavy metal-contaminated farmlands near the Xin and Xiao-Xin Waterway in Changhua County and from the Changhua Environmental Protection Bureau designate. Therefore, establishment of contaminated concentration distribution data of each contaminated farmlands were completed through soil survey. Then, main remediation technology is “Soil dilution method”, which can be implemented with soil excavation and refill to for improving contaminated farmlands in the plan. Finally, landowners can restore the agricultural usage after cancellation of the regulatory listing of the farmlands control site. On the other hand, remediation techniques of some contaminated farmlands use a large amount of soil excavation which not be included in this project, however the appropriate excavation scale and quantities of contaminated soils were estimated for reference. According to contract, the results of this project are described as below. 1. Soil supplementary survey: It has accomplished 37.17 ha contaminated farmlands. 2. Cadastral survey: It has accomplished 0 sections of farmlands. 3. Contaminated farmlands remediation area: It has accomplished 22.21 ha farmlands which consists of 21.09 ha through “Soil dilution method” and 1.12 ha through “Soil excavation method with clean soil backfilled”. 4. Contaminated soils and clean soils analysis: It has accomplished 4 sections of farmlands including TCLP analysis of contaminated soils and heavy metal analysis of clean soils. 5. Works for Soil excavation and backfilled: It has accomplished 482.95 tons soils including the treatment of contaminated soils, purchase of clean soils to refill, transportation of soils ,and so on. 6. Self-verification after remediation: It has accomplished 22.21 ha farmlands soil sampling and analysis. 7. Landowners and farmers seminar: It has accomplished 3 sections of seminar.
