In the water, this kind of floating tubes sits low.

Their Absence in an underground aquifer or an alluvial water table is a sign of Natural filtration.

Their Absence in an underground aquifer or an alluvial water table is a sign of Natural filtration.

This is due to the natural filtration ability of the alluvial plain.

Ultimately, extraction should be stopped within the confines of the Allier’s alluvial bed.

The Allier’s alluvial groundwater is a huge reservoir holding water of generally good quality.

And the alluvial deposits are particularly well fragmented into ridges of Garonne gravel of the early Quaternary.

The alluvial aquifer fed by the Rhone is threatened by an internal discharge created by the Pechiney Group.

But downstream, the impact of intensive farming is becoming too great, and the alluvial water table is suffering from excess nitrates.

The total volume extracted for human consumption from the Allier’s alluvial bed is about 2.5 m3/s.

Restore the alluvial aquifer of Bas Gapeau inland by pushing out seawater through recharge and better management of withdrawals

The overabundant exploitation of the alluvial aquifer has considerably reduced the availability of freshwater resources by salt water intrusion, especially during drought periods.
