Foreword
The environmental impacts of contaminated sites on soil and groundwater have
attracted increasing attention worldwide and emerged as an important bottleneck for
the sustainable development of human society. In China, a large number of
groundwater pollution sites have been formed due to the disorderly stacking of
garbage, the leakage of landfills, the leakage of petrochemical enterprises’ transmission pipelines, and the relocation of backward enterprises. The number of
groundwater-contaminated sites is increasing, and it has shown a trend of spreading
from cities to rural areas, from east to west, and from local to regional expansion.
Especially in economically developed areas such as Beijing-Tianjin-Hebei, Yangtze
River Delta, and Pearl River Delta, the problem of groundwater pollution is more
serious.
According to the nationwide investigations of groundwater contamination conducted by the Ministry of Ecology and Environment and the China Geological
Survey in recent years, municipal domestic waste landfills (MSWLFs), hazardous
waste landfills (HWLFs), and oil-contaminated sites (OCS) have become typical
sources of groundwater contamination that pose a serious threat to the surrounding
ecological environment. Recognizing the increasing importance of groundwater
pollution prevention and control, the Chinese government has issued a series of
plans and documents in recent years, such as the National Groundwater Pollution
Prevention and Control Plan (2011–2020), Action Plan for Water Pollution
Prevention and Control, and Action Plan for Soil Pollution Prevention and Control,
all of which place emphasis on municipal solid waste landfills, hazardous waste
landfills, and oil-contaminated sites in environmental protection.
It is challenging to identify and treat groundwater pollution as such pollution is
concealed, persistent, and complex. In China, the proactive investigation and
evaluation of typical contaminated sites will help grasp the status and trends of
groundwater pollution and provide preconditions and precise guidance for subsequent pollution prevention and control.
On the basis of systematic study of typical groundwater contamination sites in
China, Chinese Research Academy of Environmental Sciences has organized
multiple domestic and international scientific research institutions to compile the
