AUVERWATCH Project 2014-2024

AUVERgne Water CHemistry

The AUVERWATCH observation service (SO) is a long-term monitoring network of Auvergne water bodies (volcanic, alluvial, crystalline aquifers, surface water, rainfall). Set up since 2014, jointly by researchers and regional public and private water stakeholders, AUVERWATCH raises the question of the evolution of regional water quality and quantity in the face of increasing pressures linked both to human activities (urbanisation, population growth, competition for water resources, contamination, etc.) and to climate change.

AUVERWATCH currently comprises 9 sites, where hydrodynamic and physico-chemical parameters are measured and sampled monthly for the analysis of 100 to 500 parameters (mineral, organic, isotopic and microbiological chemistry) depending on the site.

The scientific questions developed in AUVERWATCH are based on 3 axes:

  1. characterise the evolution of water resources, in terms of quantity and quality, in the face of global climatic and socio-economic change
  2. Assess the reactivity of alluvial hydrosystems, which are crucial for regional exploitation (70% for all uses), to contamination;
  3. to compare studies and needs of regional stakeholders to help them better manage water resources.

AUVERWATCH is a member of national and international labelled networks:
- SNO H+ (national network of hydrogeological sites, INSU)
- SNO RENOIR (national network of observations of isotopes in precipitation, INSU)
- IR OZCAR (Critical Zone Observatory: Applications and Research, INSU)
- eLTER (European Long-Term Ecosystem Research infrastructure, ESFRI)
- Global Network for Isotopes in Precipitation (IAEA, UN)
