LABORATORY SERVICES

GCA’s individual facility laboratories were consolidated into a single Central Laboratory in 1991. While the facilities still perform some basic analysis, the heavy lifting is accomplished at the Central Laboratory, which processes 400 samples daily. Test results are generally available same day.

The Central Laboratory tests all GCA streams daily for total organic carbons, total suspended solids, metals, chemicals and other materials to ensure that incoming wastewater may be processed effectively and to provide data for regulatory compliance reporting. The state-of-the-art facility employs spectrometry, mass spectrometry, electron capture detection, flame ionization, atomic absorption and inductively coupling plasma equipment along with other equipment and instruments, much of it automated, to perform its mission. The lab employs a web-based Laboratory Information Management System that enables GCA facilities and other customers to rapidly access test status and results and performs automated quality assurance for sample analysis.

In addition to its work for GCA facilities, the Central Laboratory provides analytical services to external municipal and industrial organizations. The lab is accredited by the National Environmental Laboratory Accreditation Program (NELAP) and the Texas Commission on Environmental Quality (TCEQ). The accreditation is awarded by TCEQ based on the information submitted utilizing the NELAP quality system.
