The Edwards Aquifer Research & Data Center (EARDC) Laboratory is accredited by the National Environmental Laboratory Accreditation Program (NELAP).  The accredited laboratory and research center is 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, works with public schools as well as institutions of higher education.  The EARDC Laboratory has been providing water analysis services for a variety of chemical and biological constituents found in wells, springs, rivers, municipalities, and wastewater treatment facilities.
