SNO H+ : Ploemeur-Guidel Site
The Ploemeur-Guidel observatory (Britanny, France) is focusing on surface-depth relationships in a fractured crystalline geological context and oceanic climate. It is built on 2 sub-sites, one highly anthropized, the other in natural state. In Ploemeur, groundwater has been pumped since 1991, supplying more than 1 million m3 of clean drinking water annual at a sustainable rate. Such high productivity is explained the specific fractured network in granite and micaschists, draining deep geological layers (~400 m). Extracted water quality is very good, with limited nitrate concentration, in a region that has been strongly affected by widespread pollution. Guidel site is in a similar, but natural context. Deep iron-rich groundwater is upflowing, creating surface and deep groundwater-dependent ecosystems, and feeding a classified coastal wetland. Both sites have a very dense equipment to study rapid to long-term surface-depth exchanges: a flux tower, unsaturated zone monitoring, a network of ~50 shallow (<10m) and deep boreholes (>80m), hydrochemical, temperature and deformation. An well-characterized fractured experimental site offers the possibility to conduct experiments to test innovative instruments and develop new methodologies

- Purpose
-
Ploemeur combines both monitoring and experimental objectives: (1) Develop innovative methods for imaging subsurface structure and flow in highly heterogeneous environments; (2) Investigate the aquifer vulnerability to climatic and anthropogenic pressures: (3) Study the environment’s chemical reactivity, and water quality as extraction proceeds; (4) Estime water residence time and travel time distributions; (5) Acquire the data necessary for testing and validating hydrogeologic modeling methods designed for fractured environments. Close interactions are maintained with the local water development board
