The Eaugure projet

The degradation of water quality in natural and man-made lakes has impacts on goods and services on health and human activities. The pollution at the origin of this degradation can have as a result of either events that are difficult to control, related to meteorology and/or human activities, or recurring events that are to be linked with activities on the watersheds of water bodies. Some lakes are official swimming sites and as such, controls are carried out periodically during the summer period by the Regional Health Agencies (ARS). In this context, the analyses may include a pollution but it is generally observed a posteriori because of the delays of the analyses and the Meanwhile, bathers are in contact with poor quality water. In the other lakes, the investigations are generally conducted following complaints from users, associations and analyses are carried out, in the best case, when the pollution is well established. Bathing managers and/or operators of a reservoir must be able to ensure good water quality for users but are often helpless in the face of pollution problems, which are often very complex. It therefore seems essential to develop tools for measures that will allow them to be able to:

• Predict episodes at risk
• Monitor water quality in real time
• Make this information available to users
• To accumulate data which will make it possible in the long run to remove pollution
