Contaminated sites in China: Countermeasures of provincial governments

Abstract

Contaminated sites have caused worldwide attention and been dealt with through a variety of policies and practices both nationally and regionally. Unlike the US, Canada, Japan, and Europe, which have accumulated rich experiences in contaminated site management, China, facing serious contaminated site issues, still lacks effective strategies on issues such as remediation standards, funding resources, accountability, and stakeholders coordination. This paper collected policies for contaminated site management from 31 regions in China. A comprehensive analysis was conducted of current policies, including policy framework, number of policies and instruments, policy types, and spatial and temporal variation. We find that most regions in China, such as Beijing and Chongqing, have taken positive measures to manage contaminated sites, and that there are similarities as well as differences in policy responses and mechanisms in different regions. A multi-level objective system, combined with diverse instruments, cooperation between different stakeholders, and a multi-sectoral joint supervision mechanism emphasized by all 31 regions, are extremely important to promote sustainable site management. Specialized policies, site-specific standards, information disclosure, public participation, remediation priority and groundwater protection are urgently needed to strengthen the local framework of contaminated site management and to promote remediation projects.
