Investigating of Soil and Groundwater Contamination of Abandoned Factories (Year 2007 Project)

Absrtact	The project was the 3rd 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 July, 2007 to January, 2009. Five hundred and ninety sites were screened from the suspended factories database of Industrial Development Bureau based on fourteen high potential contaminated enterprises and one enterprise increased for wood and bamboo products manufacturing. After modification and verification the basic information and site surveyed, eighty sites abandoned before January 1, 2005 were selected to the score and screen system for the fifty priority investigation sites. In investigation stage, Environmental Site Assessment Phase I (ESA I) and the preliminary soil and groundwater investigation was executed for the fifty sites. Four hundred and seventeen sets of soil were sampled and one hundred and forty-one temporary groundwater wells were installed by direct push machine, Geoprobe. Thirty-three 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 eighty-two sets of soil were sampled and seventy-eight standard groundwater monitoring wells were constructed to sample groundwater to analyse. Thirty-two sites were found soil or groundwater contamination in the result. Most of the sites were soil pollution and only one site was groundwater pollution. The sites were suggested to announce as Soil or Groundwater Control Site by article 11 or adopt appropriate measures within a limited time period pursuant to the article 8 by Soil and Groundwater Pollution Remediation Act Enforcement Rules. In addition, the investigation guideline of abandoned industrial sites had been setup for the fourteen high potential contaminated enterprises.
