The situation is "
worrying
" for a large number of groundwater tables in mainland France in July, due to a "
significantly lower than normal
" water recharge during the winter and the ongoing historic drought, according to the bulletin of the Bureau of Geological and Mining Research (BRGM) published on Thursday 11 August.
"
In July, the emptying continues and all the aquifers observe falling levels
", indicates the BRGM.
"
This observation is not surprising, given the absence of precipitation
", according to the French public geological establishment, which notes however that the level of the emptying is slowing down "
on many layers, probable consequences of the rains at the end of June and the reduction in levies
” thanks to the restrictions ordered in almost all departments.
“
However, the situation remains worrying for a large number of aquifers which show low to very low levels
”, in particular in the “
center-west (Poitou, Brenne, Maine, Touraine)
” and in the “
south-east (Bas Dauphiné , Provence and French Riviera)
”.
“
The levels are unsatisfactory
,” insists the BRGM.
