本場址因環境地質特性、文化資產保存等影響整治作業執行，以傳統實際改善之方式進行整治在技術面與經濟面不可行，導入風險管理措施後，執行污染阻絕及管控措施，降低風險暴露途徑，藉由場址文化資產的保存，促成場址與鄰近古蹟一連串之土地活化再利用，達到地方永續發展的目標，期成為台灣北部山區著名之觀光景點。本案係第一個依據台灣《土壤及地下水污染整治法》相關規定以風險為基準之污染整治案例，歷經風險評估計畫書規劃、風險評估作業執行及整治目標擬定等程序，耗時約5.5年完成審查通過之案例，具有污染場址採行風險管理及結合土地再利用之示範作用，並透過該案例檢討污染場址採風險為基準管理與改善之執行程序，藉由風險管理，使土地得以有效利用及提升其價值，使污染場址管理制度走向更高之里程碑。

Conducting remediation at sites is deemed technically and economically impractical because of the local geological characteristics and hindrances to cultural heritage preservation. By implementing risk management measures, this heavy metal contaminated area is expected to be revitalized and transformed into a popular tourism spot in the mountainous region of northern Taiwan. This is the first successful risk-based site remediation and management project in Taiwan that complies with the Soil and Groundwater Pollution Remediation Act §24. The complete application process included planning and conducting risk assessments and developing site-specific remediation goals, that took approximately 5.5 years to complete. This case demonstrates that sustainable land use and redevelopment can be achieved through appropriate risk management measures. This case will also act as textbook material to improve execution procedures.
