The project was the 4th year of continuous project for investigation of potential soil and groundwater contamination about the abandoned industrial sites in Taiwan. It contained two subsidiary projects and was carried out by Apollo Technology Co., Ltd and MWH Americas Inc., Taiwan Branch. The execution period of the project was from March, 2009 to May, 2010. Eight hundred and ten sites were screened from the suspended factories database of Industrial Development Bureau based on twenty high potential contaminated enterprises. After modification and verification the basic information and site surveyed, nighty two sites abandoned before January 1, 2005 were selected to the score and screen system for the fifty priority investigation sites. In investigation stage, the preliminary soil and groundwater investigation was executed for the fifty sites. Four hundred and seven sets of soil were sampled and one hundred and thirty-eight temporary groundwater wells were installed by direct push machine, Geoprobe. Thirty sites which soil or groundwater pollutant concentration exceeded soil and groundwater monitoring or control standards were selected to verify. In verification stage, one hundred and fourty-six sets of soil were sampled and seventy-eight standard groundwater monitoring wells were constructed to sample groundwater to analyse. Twenty-eitht sites were found soil or groundwater contamination in the result. Most of the sites were soil pollution and only six site was groundwater pollution. The sites were suggested to announce as Soil or Groundwater Control Site by article 12 or adopt appropriate emergency measures by article 7, paragraph 5. In addition, the investigation reference guides had been setup for the fifteen high potential contaminated enterprises and the policy for further management about the abandoned industrial sites had been proposed.
