Why
Are We Not Stopping the Degradation of Our Aquifer?

DESCRIPTION OF THE SPARTA AQUIFER The Sparta Aquifer is located in southern Arkansas and at least parts of sixteen (16) northern Louisiana parishes. Current Sparta pumpage in Louisiana is 70 million gallons per day (mgd). Eight-seven percent of Louisiana aquifer consumption takes place in Ouchita, Bienville, Lincoln, Webster, Union, and Claiborne parishes, in that order. Consumption ranges from 23.5 mgd for Ouchita Parish to 3 mgd for Claiborne Parish. The current average daily outflow of water from the aquifer exceeds the existing inflow. Factors that place the aquifer in a stressed condition are:
APPROACHES TO REDUCING THE PROBLEM In 2002, MML&H published The Sparta Aquifer Study (Full study: http://www.spartaaquifer.com/ -- Sparta Commission website, under 'Studies and Reports'). For recovery of the aquifer, MML&H recommend that Louisiana Sparta pumpage must be no more than 52 mgd by the year 2025, with a 17 mgd reduction in pumpage by 2005. The aquifer region should prepare to increase its water consumption by 2025 from 70 mgd to 82 mgd. Thus, provision should be made for consumption of surface water to increase 30 mgd. MML&H ranked potential sources of surface water, from highest to lowest: Ouachita River-W. Monroe, Bayou D'Arbonne Lake, Ouachita River-Bastrop, Caney Creek Lake, Lake Bistineau. MML&H considered Lake Claiborne, also, in terms of providing for regional economic growth. WHO WILL CONTROL OUR GROUNDWATERS AND HOW? Louisiana's Evolving Water Resources Law :
