Resource and environmental risk assessment of groundwater well fields in the Beijing-Tianjin-Hebei region
Groundwater in the Beijing-Tianjin-Hebei (BTH) region has been overdrawn for a long time, and groundwater pollution is severe. Groundwater well fields (GWFs) face resource- and environment-related pressures, and their safety is a key issue restricting regional social and economic development. We evaluated the groundwater quality and drinking suitability via the entropy-weighted water quality index and the overall health risks to adults and children with an improved model. Furthermore, the risks to GWF resources were determined based on the groundwater level and its variation. The higher Na+ and NO3− concentrations were mainly due to agricultural and industrial activities. Forty-seven GWFs approached the Class Ⅳ water standard, and 25 and 4 GWFs posed high health risks to adults and children, respectively, suggesting environmental risks. Moreover, the average annual groundwater level in the groundwater depression cone of 2 shallow and 6 deep GWFs decreased by 0.25 and 3.2 m, respectively. These GWFs were substantially threatened by groundwater resource attenuation. The groundwater level of 4 GWFs slowly declined, but a deep groundwater depression cone was not formed. However, the risk to groundwater resources remained high. The resource-related and environmental risks of GWFs in the BTH region were synchronous, but the resource-related risk was higher.
期刊介绍：
Groundwater for Sustainable Development is directed to different stakeholders and professionals, including government and non-governmental organizations, international funding agencies, universities, public water institutions, public health and other public/private sector professionals, and other relevant institutions. It is aimed at professionals, academics and students in the fields of disciplines such as: groundwater and its connection to surface hydrology and environment, soil sciences, engineering, ecology, microbiology, atmospheric sciences, analytical chemistry, hydro-engineering, water technology, environmental ethics, economics, public health, policy, as well as social sciences, legal disciplines, or any other area connected with water issues. The objectives of this journal are to facilitate: • The improvement of effective and sustainable management of water resources across the globe. • The improvement of human access to groundwater resources in adequate quantity and good quality. • The meeting of the increasing demand for drinking and irrigation water needed for food security to contribute to a social and economically sound human development. • The creation of a global inter- and multidisciplinary platform and forum to improve our understanding of groundwater resources and to advocate their effective and sustainable management and protection against contamination. • Interdisciplinary information exchange and to stimulate scientific research in the fields of groundwater related sciences and social and health sciences required to achieve the United Nations Millennium Development Goals for sustainable development.
