Site Assessment and Investigation for Soil and Groundwater Potential Contamination of Abandoned Factories (2015)
The project, “Site Assessment and Investigation for Soil and Groundwater Potential Contamination of Abandoned Factories (2015),” including two subprojects was conducted by Apollo Technology Co., Ltd and MWH Americas Inc., Taiwan Branch. The execution period of this project is from May 2015 to November 2016.
The project contains two goals: continuing the process of the investigation and management of abandoned factories in Taiwan and improving the strategies for environmental risk assessment system. Our team aims not only to accelerate the investigation to complete the management of abandoned factories, but to apply the system to the operating factories and other industries with pollution potential so that we can organize a map with the industrial plants with pollution potential and establish the profiles of the abandoned factories as the basis of the administrative management and policies for soil and groundwater environment at the abandoned factories in Taiwan.
The project implemented the survey to a total of 1,693 abandoned factories which were proclaimed with high pollution potential (Phase 2) based on the environmental risk assessment in order to accelerate the management process. Particularly, the team selected 1,056 factories classified as Category A (with the feasibility for investigation based on the in-situ status), red light (high pollution potential), and orange light (medium-high pollution potential) to conduct the environment assessment at the sites.
After the assessment, 39 sites were ranked as the prior objects for contaminated soil and groundwater investigation. Accordingly, groundwater or soil pollution was found in 20 sites among the objects. The discovery rate is 51.2%.
As a result, Environment Protection Administration called a conference to discuss the follow-up measurement for the polluted abandoned factories in Taiwan and claimed the local environmental protection bureaus to take the administrative control on the certain sites and investigate the pollution source. Also the authority needed to investigate if the inhabitants of those areas utilize groundwater for agricultural or fishery purposes avoid the expansion of the pollution range.
On the other hand, in order to enlarge the scope of the environmental risk assessment system of abandoned factories, not only did we add 80 more industry categories as the objects for environmental risk assessment, but presented different pollution potential of the operating factories via signal light classification. The ranking principal was based on the parameters of the screening formula for assessment system of abandoned factories. In this way, we are able to manage the factories much more efficiently by the signal light classification and establish the profiles of the abandoned factories to achieve the goal to amplify the environmental risk assessment system’s capability.
In addition, we held the “Conference and Exhibition for Precaution and Management of Soil and Groundwater Pollution.” With 386 participants, we achieved to promote the notion of precaution and education of soil and groundwater pollution. We also held a micro film contest. 31 pieces were awarded among total 114 participating works. Other than those interactive events, three technologies were granted patents by the Intellectual Property Office, Ministry of Economic Affairs, R.O.C. The performance of this project was highly affirmative, and it could support the promotion of liability insurance of polluted factories. The authority could utilize our results to design the insurance policies and fees for polluted factories.
