Groundwater bodies - Guadeloupe - State of the Places Version 2019

Description

A body of groundwater is a separate volume of groundwater within one or more aquifers, constituting the basic delineation of aquatic environments intended to be the unit of assessment for the WFD. Groundwater bodies are derived from work done on the BDLISA repository. The water bodies are divided according to the following main principles: - Water bodies are defined on the basis of geological and hydrogeological criteria; - Redistribution of water bodies to take account of the effects of anthropogenic pressures must remain limited; - The boundaries of water bodies must be stable and sustainable; - Like bodies of surface water, the delimitation of bodies of groundwater is organised on the basis of a typology. This typology is largely inspired by the one developed for hydrogeological entities defined in the context of the BDLISA revision. It is based on the geological nature and hydrodynamic behavior or "large" operation of aquifer systems (nature, flow velocity). It comprises two levels of characteristics (main and secondary); - Water bodies may trade with each other; - All water withdrawals for drinking water supplying more than 10 m3/day or used to supply water to more than 50 persons must be included in a body of water; - Deep groundwater, unrelated to rivers and surface ecosystems, from which no abstraction takes place and which is unlikely to be used for drinking water because of its quality (salinity, temperature, etc.), or for technical and economic reasons (disproportionate cost of abstraction) may not constitute water bodies; - Given its size, a body of water may have a certain spatial heterogeneity both in terms of its hydrogeological characteristics and its qualitative and quantitative status; - At any point several water bodies may overlap.
