Could drought solutions lie underground?

Aquifer recharge strategies could maximize water resources, according to Andrew Stone, executive director for the American Ground Water Trust (AGWT). The organization claims that a process known as aquifer storage recovery (ASR) is a cost effective solution for water needs.

Mike Massey, president of the Upper Trinity Groundwater Conservation District (UTGCD), said he’s heard of systems working to enhance the re-charge of an aquifer, but has no direct contact with anyone who is injecting water into an underground storage facility such as a depleted aquifer.

The Upper Trinity GCD includes Hood County.

A conference from 8 a.m. to 5 p.m. Wednesday, July 24, in Austin will cover underground resources for water management flexibility in Texas.

The program is organized by AGWT and co-sponsored by the Texas Water Development Board.

“Texas is in the grip of drought,” Stone said.

“Towns and farms are suffering because existing water storage is depleted. Building surface reservoirs in areas of high evaporation does not make sense.

“Water, available seasonally, or during storms, can be captured, stored underground in depleted aquifers and pumped back to the surface for use in times of need,” Stone contends.

ASR technology has been used as a water management strategy all over the world, with over 100 operating systems in the USA, Stone noted.

At the conference in Austin, experts with ASR experience will explain the challenges, feasibility, potential, regulatory concerns and the economic and environmental benefits of ASR.
