OTWSC Webinar, January 23 - Edwards Aquifer Recharge Zone Monitoring Project
Edwards Aquifer Recharge Zone Monitoring Project
Oklahoma-Texas Water Science Center Webinar, Thursday, January 23rd, 11 am Central
WEBINAR
City planners and water managers need high-quality water-resource information to make informed decisions about water availability, water quality, aquifer protection, and infrastructure growth. In 2012, the USGS restructured their monitoring program with the San Antonio Water System (SAWS) to focus on urbanization and development occurring on the Edwards Aquifer Recharge Zone (EARZ). The design and implementation developed an ongoing monitoring network to track changes in water-quality from aquifer recharge across the EARZ and into the Edwards aquifer. Since 2012, the network has grown from 5 to 13 sites, including surface water and groundwater sites, to characterize different geographic areas on the recharge zone. The USGS-SAWS Urban Hydrology Network (UHN) provides reliable and unbiased water-quality and hydrologic data that informs SAWS and regional stakeholders about the status of and long-term changes affecting the Edwards aquifer, the primary public water supply for the City of San Antonio. Steve and MaryLynn will introduce the Urban Hydrology Network and discuss some recent results that have yielded new understanding into the water quality of the Edwards aquifer.

PRESENTERS
MaryLynn Musgrove is a Research Physical Scientist with the USGS Oklahoma-Texas Water Science Center. Her research interests focus on using geochemistry to better understand groundwater systems with a focus on karst. Much of her work over the past 30 years has included the central Texas Edwards aquifer. She holds a B.S. in Geology from the University of Florida, and a Master's and Ph.D. in Geological Sciences from the University of Texas at Austin.
Steve Opsahl is a Hydrologist with the USGS Oklahoma-Texas Water Science Center South Texas Branch located in San Antonio. He is currently interested in surface water and groundwater quality, stream/aquifer interactions, anthropogenic and natural tracers in aquatic systems, emerging contaminants, and the development of new groundwater monitoring tools. Steve received a bachelor’s degree in microbiology from the University of Texas at Austin and followed this with a Ph.D. in Marine Science from the U.T. Austin Marine Science Institute in Port Aransas, TX.
