At present the tendency of increase in groundwater use for public water supply is observed. This can be explained by the well-known fact that groundwater, as a source of water supply, has some advantages in comparison with surface water. Groundwater generally contains micro- and macrocomponents needed for the human body, does not require expensive treatment; and is much better protected from contamination. Groundwater resources are much less susceptible to seasonal and long-term variations. They are usually located near water users. Groundwater is essentially the only source of water supply in regions where surface water freezes or dries up. Groundwater is not only natural resources but also an important component of the environment. Any changes in other components of the environment such as atmospheric precipitation, evaporation, river runoff, etc., influence groundwater resources and quality. And vice versa variations in groundwater regime especially due to the water withdrawal in large scales cause changes in landscapes, vegetation, sea water intrusion, activization of karst processes.
- to analyze the existing experience of groundwater studying, use and protection in different countries
- to prepare the analytical review of modern state of groundwater use in different nature and climatic and anthropogenous conditions
- to improve the methodology of regional assessment and mapping of groundwater resources
- to analyze existing case studies of the influence of groundwater withdrawal in large scales on land subsidence, vegetation and activization of sea water intrusion into the coastal zone
- to predict the changes of groundwater recharge in 21 century in different climatic scenarios
Working Group Committee
The Working Group Committee consists of:
Dr. Igor Zektser (Russia) – Chairman
The Group’s inception activity was participation in an International Scientific and Practical Conference "Drinking Groundwater: study, use, and information technologies” organized jointly by VSEGINGEO Institute, Federal Agency for Subsoil Use Department of Natural Resources and Environment of Russian Federation, and the International Association of Hydrogeologists with participation of the IUGS-GEM Working Group on Drinking Water (Moscow region, 18-22 April, 2011). The conference brought together 208 scientists from 91 companies and scientific and research organizations of Russian Federation and 8 other countries (Azerbaijan, Byelorus, Bulgaria, Germany, Kazakhstan, China, Uzbekistan, Ukraine), representatives of UNESCO and the IAH. During the Conference 127 reports were discussed and 8 presentations were given.
• Proceedings of the International Scientific and Practical Conference "Drinking Groundwater: study, use, and information technologies” in 4 parts, Moscow, 2011 Papers provided by Dr. I. Zektser, Dr. Q. He, Dr. A. Dzuba, Dr. B. Borevskii were included into the Proceedings;
• Proceedings of the Conference of Russian
Academy of Sciences “The sustainability of water sources and coastal
territories and the risks of their use”, Kaliningrad, 2011. Papers of Dr. I.
Zektser, Dr. A. Dzuba and Dr. B. Borevskii were included into the Proceedings;
A workshop and field visits on Drinking Water took place in Vilnius, Lithuania, in June. Papers on drinking water issues in Latvia and Lithuania were published subsequently in a GEM Newsletter. A review of the World experience in groundwater resources study and assessment in different natural and climatic zones was commenced.
The Working Group held a workshop on “Regional Assessment and Mapping of Groundwater Resources” in Warsaw, Poland, and another on “Fresh groundwater as a strategic resource for water supply” at the International Multidisciplinary Scientific GeoConference and Expo SGEM at Albena, Bulgaria. .
The Working Group was represented in:
· the scientific session of the Faculty of Geography of the University of California, LA (USA) on modern problems of hydrogeology including regional assessment of the resources of fresh groundwater and their use for water supply; and
· the All-Russian Scientific and Practical conference “State, problems and prospects of exploration and research work in the field of hydrogeology, engineering geology, geocryology and geoecology”. At the latter, reports were given on the activity of international organizations in the field of hydrogeology.
A full meeting of the Working Group on assessment of the use of groundwater as the reserve source of water supply in emergency situations was held in Vilnius, Lithuania in May 2015.
The Drinking Water Working Group is currently involved in the organization of National Conference on Groundwater in Siberia and the Far East to be held in Yakutia in June 2015.
A paper on “Uncertainties in the assessment of climate Change Impact on groundwater” has been submitted to Episodes and is due for publication in 2015.
A guide book on methods for, and experience on, regional assessment of groundwater resources for water supply and irrigation in different climatic and anthropogenic conditions is planned by for 2016.
