GZA's Aquatic Toxicity Laboratory was established in 1988 to perform whole effluent toxicity (WET) testing of wastewater samples from industrial and municipal sources using both freshwater and saltwater aquatic species. Our laboratory performs screening, acute and chronic toxicity tests on wastewater treatment plant and industrial facility discharges including processed wastewaters, stormwaters and non-contact cooling waters. We also perform whole effluent toxicity tests on everything from commercial / industrial manufactured products to remediated groundwaters. For facilities that are experiencing difficulty in controlling effluent toxicity, we provide toxicity identification and toxicity reduction evaluations.

 

Our laboratory is widely known and is well regarded by state environmental regulatory agencies and the U.S. EPA.  We have consistently earned EPA’s highest rating on all of our protocols submitted as a participant in the WET Testing portion of EPA’s annual Discharge Monitoring Report Quality Assurance Performance Evaluation Program.  These technical credentials are backed with outstanding technical support and a philosophy of proactive customer service provided by a knowledgeable and responsive team.  We pride ourselves on providing all of our reports, including toxicity evaluations in timelines compliant with both our clients business and regulatory needs.
