A global perspective on assessing groundwater quality

Bruce Misstear et al.

Summary: An assessment of global groundwater quality is necessary due to the threats from human and natural contaminants. This essay discusses the challenges involved, such as the large number of relevant parameters, lack of data, and complexity of groundwater systems. Indirect methods and citizen science are being used to supplement direct monitoring data, and a new web portal is being developed to complement existing databases.
