Water quality is of considerable importance to protecting ecosystems, maintaining amenities and safeguarding health. Water-quality monitoring is an essential part of environmental and ecosystem protection and water supply, including for drinking water.
Monitoring is also a requirement of numerous pieces of national and European legislation aimed at environmental protection. Examples include the Water Framework Directive, Groundwater Directive, Drinking-Water Directive and Nitrates Directive.
Investigation of water quality is a central part of BGS activities. We have a long history of research into the inorganic and organic chemistry of streamwaters and groundwaters, both across the UK and overseas. Investigations include:
What is the trace element content of bottled water in your local supermarket? How does it vary? How does it compare with in-situ groundwater from the same sources?
Assessing the occurrence of non-regulated trace elements in drinking water for public supply in England and Wales.
