Ground Water Resources in Louisiana

Did you know? Although over 70 percent of the Earth's surface is covered with water, less than 1 percent of this water is available for human consumption.

Louisiana is blessed with an abundance of high quality ground water. In fact, ground water is the primary source of drinking water for 61 percent of Louisiana's residents. Of this 61 percent, 12 percent use domestic wells and 49 percent rely on public water supplies. (DOTD/USGS, 1995)

Ground water is found in aquifers and our state has eleven major aquifers. These are permeable, saturated zones of rock, sand or gravel that contain sufficient water to yield usable amounts to wells.

Everyday water is withdrawn from our aquifers for the public’s use, industry’s use, as well as for power-generation, farm and irrigation and aquaculture purposes.

Generally speaking — water consumption is on the rise and that is stressing   available water supplies and distribution systems. Indeed, water is a renewable natural resource, but climate change, prolonged drought conditions and extensive demand can be reason for concern.

A recent government survey points to at least 36 states that expect to experience local, regional, or statewide water shortages by 2013. But, by using water more efficiently, we all can help preserve water supplies for future generations, save money, and protect the environment.

Louisiana and the rest of the nation are looking to establish best management practices and policies to protect this most important natural resource.
