USGS scientists helping to restore depleted Armenian aquifer

SIOUX FALLS, S.D. (AP) - Some South Dakota scientists from the U.S. Geological Survey are helping to restore a depleted aquifer in Armenia.

The USGS says the growth of aquaculture to raise trout, sturgeon and other cold-water fish has increased withdrawals of critical groundwater in the Ararat Basin over the last 10 to 15 years.

The USGS is working with the U.S. Agency for International Development Armenia and others to develop scientific tools for water-resource managers to understand and predict consequences of such management decisions.

Mark Anderson is director of the USGS South Dakota Water Science Center. Anderson says the goal is to assist Armenia in the restoration of the aquifer and the move toward more sustainable water uses.

The scientists traveled to Yerevan, Armenia, during a recent two-week trip.
