Edwards Aquifer Optimization Program Update (continued)
by John Hoyt, Program Manager - Aquifer ScienceJuly 8, the board voted to approve an interlocal coop-
eration agreement between the Authority and San
Antonio Water System (SAWS) for the continuation
of work to better define the freshwater/saline water
interface within the Edwards Aquifer. The Authority
and SAWS have been cooperatively funding saline
water studies since 1998. The 2003 agreement will
result in the installation of three additional interface
monitoring wells in south central San Antonio,
continued data collection at existing monitoring
wells, and the initiation of a computer model to
better characterize the interface. The board also
approved a contract with George Veni and Associates
(GVA) for tracer testing and stormwater monitoring.
The work by GVA will serve to define flowpaths in the
aquifer in the area of major springs and will serve to
characterize stormwater quality recharging the aquifer
in northern Bexar County.On July 23, the R&T Committee voted to recommend the board approve a joint funding agreement
(JFA) between the Authority and the American Water Works Association Research Foundation
(AWWARF). The JFA, if approved by the board, is for work to develop a new generation computer
model for the enhanced characterization and representation of flow through karst aquifers. The
work will be funded jointly by the Authority, Southwest Florida Groundwater Management District,
and AWWARF. Six universities and two groundwater management districts will also provide in-kind
services for the project. Southwest Research Institute (SWRI) in San Antonio will serve as the primary
model development contractor for AWWARF. SAWS will serve as the local American Water Works
Association sponsor for the project.
In addition to the OTS-related items discussed above, the following OTS-related studies are currently
underway or have been completed:
" Texas wild-rice reproduction.
" Comprehensive and Critical Period Monitoring Program to Evaluate the Effects of Variable
Flow on Biological Resources in the Comal and San Marcos Springs Ecosystems.
" Cagle's Map Turtle instream flow and habitat requirements (completed).
* Edwards Aquifer computer model development.All
