WITHOUT ACTION, OUTLOOK MURKY FOR WATER SUPPLY IN REGION

McGEHEE - Board members of the Boeuf-Tensas Water Conservation
Project received a frightening prediction Tuesday when John Czarnecki
of the United States Geological Survey presented computer-generated
models of what eastern Arkansas will look like in the year 2049 if
something is not done about the amount of groundwater presently
being used but not replenished.
Ann Cash, executive director of the project, agreed that if the present
rate of consumption without replenishment continues, eastern Arkansas
will look like a sinkhole with only river water and rainwater available.
Nine counties and parts of two others have already been declared
critical because the drawdown on the groundwater level - the fresh
water underneath the earth's surface - has reached 50 percent or less.
The counties that are listed as the mose critical are Jefferson, Lonoke,
Prairie, Arkansas, Columbia, Union, Ouachita, Calhoun and Bradley.
Eastern portions of Pulaski and White counties also have been
Czarnecki said that Arkansas ranks fourth among all states in total
groundwater usage, primarily because of agricultural needs.
Arkansas County with its vast rice crops is the biggest user of
Czarnecki said there are more than 45,000 wells in the eastern portion
of the state that, according to numbers available in 1995, pumped 5
billion cubic feet of water per day.
Arkansas County alone pumps around 550 million gallons per day from
the alluvial aquifer.
Since 1960, the water table has dropped roughly 80 feet.
In the area of primary concern to the Boeuf-Tensas conservationists,
geologists are already seeing cones of depression because of the
drop in the water table.
What the water distribution district hopes to do is look at alternative
models that would at least help stabilize the water table, if not help it
Those alternatives could include the use of reservoirs and pumping
water from the Arkansas River into area canals to deliver water to 1.2
million acres, the majority of which is farmland.
Cash said there are at least two more years left on the study phase of
the project, with 10 years of construction after that.
She added that if the problem is not addressed, there will come a time
when the aquifer will be unable to recover.
"It's like Humpty Dumpty," she said. "It can't be fixed."
The board met at the Corps of Engineers headquarters in Vicksburg in
November to establish objectives and constraints in the feasibility
The objectives are to stabilize the alluvial aquifer, sustain/enhance and
restore the area ecosystems, reduce the flood damage in the
residential and agricultural areas and improve water quality.
The group is attempting to maintain the aquifer at a minimum of 50
percent saturation level while avoiding an impact on the ecosystem.
That includes impacting endangered species as well as maintaining
wetlands and introducing or spreading invasive species.
The feasibility study will also examine ways of maintaining a minimum
flow in the Arkansas River and the natural rise and fall of Bayou
Cash added that an important consideration is that the project will not
induce flood damage to Louisiana.
