Lab

The San Antonio River Authority (River Authority) Regional Environmental Laboratory offers analytical testing services throughout Texas for non-potable water, solid and chemical materials, and environmental water quality monitoring efforts. The laboratory began operating in 1966 with the sole focus of supporting River Authority wastewater treatment plant operations. Through the decades, the laboratory has expanded its scope of testing services to include surface water, stormwater, and molecular science bacterial source tracking. In 2008, the River Authority Regional Environmental Laboratory obtained certification from the National Environmental Laboratory Accreditation Program (NELAP).
