Atkins' accredited environmental toxicology laboratory, located in state-of-the-art facilities in Houston, Texas, has been in continuous operation for three decades.

Atkins’ environmental toxicology laboratory provides clients with timely, high-quality testing services to support project needs from its 8,500-square-foot, state-of-the-art facility in Houston, Texas. We offer door-to-door sample handling and transport (including sample collection, where needed), custom reporting, and computer-based information management tools for tracking of permit requirements to assure compliance with testing schedules.

We maintain an extensive culture facility for the production of test organisms routinely used in the laboratory. Our experienced toxicologists, chemists, and environmental engineers investigate and identify the causes and sources of toxicity and provide cost-effective solutions for compliance with permit requirements.

We support material testing for open-water or confined disposal sites conducted in accordance with U.S. Environmental Protection Agency (USEPA), U.S. Army Corps of Engineers (Corps), or regional guidelines. Our lab is fully accredited in the State of Texas, with secondary accreditations from the states of Florida and Louisiana. Click here to view our accreditations.
