Edwards Aquifer Research & Data Center



Dr. Schwartz
EARDC DirectorDr. Benjamin F. Schwartz

 Welcome to the Edwards Aquifer Research & Data Center (EARDC).  We are a NELAC certified lab and research center found within the College of Science & Engineering. EARDC was established in 1979 with special funding for Texas State University to provide a public service in the study, understanding and use of the very fragile natural resource, the Edwards Aquifer. 

EARDC takes an active role in water education issues and works daily with public schools as well as institutions of higher education.  The Edwards Aquifer Research and Data Center has been providing water analysis services since 1979. Samples are analyzed from wells, springs, rivers, municipalities, and wastewater treatment facilities for a variety of chemical and biological constituents.

The Edwards Aquifer Research & Data Center is organized around four different areas; Data Center, Technical Center, Education Center and Research Center.
