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 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. 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.
