本計畫針對環保署列管的152處丙丁級場址進行現場勘查，並篩選30處場址具高地下水污染潛勢之場址，進行地下水污染查證工作，以評估場址風險，作為環保機關進行污染管制與應變措施之依據。152處丙丁級場址經逐一勘查後，發現大部分場址與上一計畫(93年)勘查時並無明顯差異，且各縣市環保局回覆之資料亦顯示這一年來並無新的清理作業執行。15處93年度已調查場址，新設15口標準監測井，檢測結果均未達管制標準。另經本(94)年度篩選出15處具地下水高污染潛勢之場址，共設置45口簡易井，檢測發現台南縣R018EPA0175場址之總酚及鉻達管制標準，其餘14處場址均未達管制標準。但彰化縣N009EPA0013、雲林縣P008EPA0152、及台南縣R016EPA0126等3處場址地下水有明顯污染之跡象。依據先前地下水檢測結果，再篩選出5處地下水有污染跡象者，進行第二階段地下水查證，共新設15口標準監測井。檢測顯示台南縣R018EPA0175場址之總酚、鉻及達地下水污染管制標準，其餘4處場址則是有污染跡象。針對台南縣R018EPA0175場址進行污染關聯性調查，確認其地下水污染與該場址之廢棄物有直接關係，發現含重金屬有害事業廢棄物，並依HRS場址評分系統計算達53.9分。最後，本計畫完成之相關資料均匯入土壤及地下水污染整治基金會之「土壤及地下水污染場址資訊管理系統」。

The purposes of this plan were to visit the 152 classified C and D illegal dumping sites listed by the ROC EPA, and to select the most possible contaminated groundwater 30 sites from 152 sites to carry the groundwater pollution survey, and then offered the basis for environmental officials to take follow-up control or emergency response measures in the future. After visited the 152 classified C and D illegal dumping sites, and based on the reply data from the related local Environmental Protection Bureau, it showed that there were no more clean-up actives carried out in 2004 and the situation were still the same as 2004. At the primary stage of this project, there were 15 standard groundwater monitoring wells were installed on the downstream of these sites screened by the last project and examined the groundwater quality. The examined result showed that 14 sites complied with the Taiwan Groundwater Pollution Control Standard, and only in one site, named “the opposite area of Pingtung Country Gausu Hsiang Pu-Qiang-Lun sector land number 323-6 (T008EPA0048)”, discovered the groundwater contaminants. Besides, another 15 possible groundwater contaminated sites were selected to be installed 3 simple wells of each site, and examined the groundwater quality. Based on the examined results of these simple wells, only the total phenols and chromium concentrations in groundwater at the Tainan County Hou-Pi Hsiang Xin-Dong Village No. 148-20 Site (R018EPA0175) exceed the Taiwan Groundwater Pollution Control Standard and the other 14 sites were not. However, there were obvious contaminated evidences founded in the “Changhua County Dacheng Township Shang-Feng Sector land No. 577 and land No. 578 Site (N009EPA0013)”, “Yunlin County Dapi Township Beigang River Lu-Liao Dike Site (P008EPA0152)”, and “Tainan County Guanmiao Township Shen-keng-Zi Sector land No.707-1 Site (R016EPA0126)”. From the preliminary groundwater survey, five sites with contaminated evidences were enforced into the second phase investigation. Another 15 standard groundwater monitoring wells were installed and examined. Based on the examined results of these monitoring wells, the total phenols, chromium and arsenic concentrations in groundwater at Tainan County Hou-Pi Hsiang Xin-Dong Village No. 148-20 Site (R018EPA0175) exceed the Taiwan Groundwater Pollution Control Standard and the groundwater of the other 4 sites showed contamination but complied with the standard. To investigate the groundwater pollutants source of Tainan County Hou-Pi Hsiang Xin-Dong Village No. 148-20 Site (R018EPA0175), the investigation of relationship between the buried waste and the groundwater pollutants were carried. The investigation of relationship results showed that the groundwater pollution was related with the buried waste, and the waste contained the hazardous heavy metal. The Hazardous Ranking System was applied to re-score the site, and the site’s score up to 53.9. Finally, all results of the plan were updated into the Information Management System for Soil and Groundwater Contaminated Sites established by the ROC Soil and Groundwater Pollution Remediation Fund.
