The Texas Commission on Environmental Quality offers
accreditations for all environmental laboratories according to
standards adopted by the National Environmental Laboratory
Accreditation Conference (NELAC).
Currently, the Commission also offers certifications based on
the U.S. Environmental Protection Agency’s Manual for the
Certification of Laboratories Analyzing Drinking Water.
Laboratories providing data for compliance with the Safe
Drinking Water Act must be certified or accredited under one of
these two programs.
