Water Pollution Control Measures and Test Reporting Management Regulations Article 85
Enterprises or sewage systems that use soil for treatment shall take following actions with respect to monitoring of the soil and groundwater, in addition to acting in accordance with Table 1:I. Where the total area for soil treatment is less than one hectare, a groundwater monitoring well shall be set up at the midpoint between the upstream and downstream of the groundwater flow and a soil sample shall be taken from the well.II. Where the total area for soil treatment is more than 1 hectare and less than 25 hectares, a groundwater monitoring well shall be set up in the upstream and downstream of the groundwater flow, respectively, and a soil sample shall be taken from each well.III. Where the total area for soil treatment is more than 25 hectares and less than 100 hectares, a groundwater monitoring well shall be set up in the upstream, midstream, and downstream of the groundwater flow, respectively, and a soil sample shall be taken from each well.IV. Where the total area for soil treatment is more than 100 hectares, more than 5 groundwater monitoring wells shall be set up and more than 5 soil samples shall be taken. The groundwater monitoring wells and soil samples shall be set up and taken in the upstream, midstream, and downstream of the groundwater flow and surrounding area.The soil samples referred to in the preceding paragraph shall be mixed shallow-layer samples.The competent authority may, with reference to the actual requirements with respect to the groundwater hydrology and water quality condition, order an enterprise or sewage system to increase the number of the groundwater monitoring wells and soil samples to be taken.
中文原文 水污染防治措施及檢測申報管理辦法第85條
事業或污水下水道系統採土壤處理者，其土壤及地下水監測，除依附表一規定辦理外，應另依下列規定辦理：
一、土壤處理土地總面積未達一公頃者，於地下水流之上、下游中間處，設置一口地下水監測井，採取一個土壤樣品。
二、土壤處理土地總面積達一公頃以上，未達二十五公頃者，於地下水流之上、下游處，各設置一口地下水監測井，各採取一個土壤樣品。
三、土壤處理土地總面積達二十五公頃以上，未達一百公頃者，於地下水流之上、中、下游處，各設置一口地下水監測井，各採取一個土壤樣品。
四、土壤處理土地總面積達一百公頃以上者，應設置五口以上之地下水監測井及採取五個以上土壤樣品；其地下水監測井及土壤樣品應於地下水流之上、中、下游及四週設置及採取。
前項土壤採樣應採淺層混合樣品。
主管機關得依地下水水文、水質狀況等實際需要，命事業或污水下水道系統增加地下水監測井及土壤採樣數量。
