Welcome to the site for the IAH Commission on Mineral and Thermal Waters (CMTW).

CMTW is one of the standing bodies (working groups) of the International Association of Hydrogeologists (IAH), established in August 1968 in Prague, Czechoslovakia, during the 23rd session of the International Geological Congress. Since then CMTW has convened 42 annual meetings.

The great majority of CMTW meetings are organized by a scientific advisory board of noted hydrogeologists and other related scientists, some of whom have participated since its inception. The majority of these events have taken place in Europe, with members of the Commission from other continents of Africa, Australia and North America attending regularly. Additional CMTW meetings are also organized within the IAH congress.

One of the main objectives of the Commission is to bring together scientists, engineers and other professionals dealing with mineral and thermal waters. The CMTW meetings and sessions give participants unique, direct and visual opportunities to become familiar with specific problems in the field of hydrogeology and exploration and utilization of mineral and thermal waters; to exchange views, knowledge and know-how; to undertake collective efforts to solve important problems concerning exploration, utilization and management of mineral and thermal waters. Nowadays, members are mostly hydrogeologists working in various governmental agencies, universities, research institutions and private organizations. Some members, although retired, remain active as consultants in their field.

CMTW’s activities are also directed in education, particularly dissemination of knowledge and results of scientific research and support of innovative solutions in the field of applied hydrogeology. For this reason, the Commission supports and encourages its members to publish the results of their activities. Since 2000, a regular collection of the best works of CMTW has been published in Environmental Earth Sciences Journal (formerly Environmental Geology).

IAH is an international non-profit organisation that promotes sound development and management of groundwater – seen by many as the worldwide family of hydrogeologists.

We hope our website will encourage you to find out more about the commission and also to become involved.
