Centre for Ecology and Hydrology – Future Flows and Groundwater levels Project


The Future Flows Project was a partnership project co-funded by the Environment Agency of England and Wales, Defra, UK Water Industry Research, the Centre for Ecology & Hydrology, the British Geological Survey and Wallingford Hydrosolutions. The project ran between March 2010 and Spring 2012.

It carried out a consistent assessment of the impact of climate change on river flows and groundwater levels across England, Wales and Scotland.

Global Groundwater Information system


The Global Groundwater Information System (GGIS) is an interactive, web-based portal to groundwater-related information and knowledge. The main purpose of the system is to assist in the collection and analysis of information on groundwater resources and the sharing of this information among water experts, decision makers and the public.

GOV.UK - Defra


The Groundwater (Water Framework Directive) (England) Direction 2014 revokes and replaces the Groundwater (Water Framework Directive) Direction 2006, which applied to both England and Wales. Similar Directions have been issued by the Welsh Government to Natural Resources Wales. The Directions came into force on 16 September 2014.

The Groundwater Foundation


The Groundwater Foundation is a US non-profit organisation that educates people and inspires action to ensure sustainable, clean groundwater for future generations.

Since its inception in 1985, it has offered a variety of programs and projects for youth, individuals, and communities to learn more about groundwater and how they can help protect it.

Groundwater Governance



Groundwater Governance - A Global Framework for Action (2011-2015) was a joint project supported by the Global Environment Facility (GEF) and implemented by the Food and Agriculture Organization of the United Nations, jointly with UNESCO's International Hydrological Programme, the International Association of Hydrologists and the World Bank. 

The project was designed to raise awareness of the importance of groundwater resources for many regions of the world, and identify and promote best practices in groundwater governance as a way to achieve the sustainable management of groundwater resources.


Updated versions of Groundwater Governance 'Shared Global Vision for 2030', 'Global Framework for Action' and 'Global Diagnostic' are available to download from the project website.

Groundwater Protection and Restoration Group


The Groundwater Protection and Restoration Group (GPRG) at the University of Sheffield is an international centre of excellence for applied research on groundwater. The GPRG seeks to make a practical contribution to the protection, restoration and sustainable management of groundwater through international quality scientific research, supported by engineering applications and wide dissemination.

Groundwater Relief


Groundwater Relief is registered with the UK Charity Commission as a Charitable Incorporated Organisation (CIO).

It is an organisation of hydrogeologists and groundwater professionals. Members work within water utilities, mineral extraction companies, environmental consultancies, oil and gas companies, government and educational institutions from across the globe.

The objective is to prevent and relieve poverty and sickness and promote the good health of people anywhere in the world by developing their and their water providers’ capacity to sustainably use and develop groundwater resources.

International Groundwater Resources Assessment Centre


IGRAC is a UNESCO centre that works under the auspices of the World Meteorological Organization (WMO) and is supported by the government of The Netherlands.


Since 2003, IGRAC has facilitated and promoted sharing of groundwater information and knowledge, focusing on aquifer assessment and groundwater monitoring. Gradually, IGRAC is expanding its interest to other groundwater-related topics, such as governance, training and climate change adaptation.


The Global Groundwater Monitoring Network (GGMN) is a network of networks, set up to improve quality and accessibility of groundwater monitoring information, and subsequently our knowledge on the state of groundwater resources.

UK Groundwater Forum


The UK Groundwater Forum is an informal grouping of technical, industrial and research organisations which have an involvement with groundwater.


 It was formed in 1995 as a means of consulting stakeholders during a study involving a strategic review of groundwater issues and research needs. The forum now operates a highly informative website, sponsors open meetings on topical groundwater issues and produces educational and technical publications.

Member organisations include the Environment Agency and the British Geological Survey.

Aims of the UK Groundwater Forum

  • Raise the awareness of groundwater and the role it plays in supporting the environment and in water supply
  • Provide information on groundwater, targeted at specific groups such as decision makers, policy makers and schoolchildren
  • Improve groundwater education in schools by providing educational resources, or links to existing resources
  • Promote careers in groundwater-related professions
  • Produce and disseminate information and facilitate discussion on topical groundwater issues within the water and environment community
  • Provide a means for those in the water and environment community to share information

The website provides information on the WFD and the Groundwater Directive. In addition to policy and legislation, other topics include groundwater management, groundwater quality, climate change and extreme events, and a very useful background information section.


'Groundwater - our hidden asset'

This book provides basic information about groundwater and the UK groundwater industry.


Excerpts are available on the ‘Groundwater in Depth’ section of the website:


The re-launch of this popular publication was incorporated into the Geological Society/International Association of Hydrogeologists conference ‘Groundwater – Managing Our Hidden Asset’ 13-16 September 2016.


The e-book is available to download from the UK Groundwater Forum website.
