Abstract

This paper aims to identify current situation of soil contamination countermeasures for England and Japan. It examines the legal framework and estimated stock measurement on contaminated land between the two countries. The primary findings are as follows: 1) The main differences in the Acts for soil contamination between the two countries are found in triggers for inspection, initiatives and ways of handling the whole process of remediation; 2) The number of estimated contaminated sites in the both countries is approximately 330,000. And the rate of site investigations is approximately three times in England than that in Japan; 3) Regarding the soil contamination counter measure, Environmental Act (EPA1990) and planning system (Planning 1990) are closely and jointly well operated in England; and 4) In England the local authority needs to take a strategic approach to the inspection of sites within their district boundary under EPA1990 and each contaminated site is handled by a risk based approach (CLEA) on the comprehensive evaluation of pollutant linkage and land use.
