Stormwater Filtration
The US Geological Survey reports that half of the drinking water in America comes from groundwater reserves, while the other half comes from lakes and rivers. Both of these sources are adversely impacted when impervious surfaces like buildings, parking lots and roads prevent rain from infiltrating back into the ground.
Groundwater reserves are not being recharged and shallow groundwater flow systems, which maintain the base flow conditions between rainfall events in lakes and rivers, are reduced.
