During the 1970’s Whole Effluent Toxicity (WET) tests were developed by the United States Environmental Protection Agency (USEPA) as a means to enforce the Clean Water Act’s prohibition of the discharge of toxic pollutants in toxic amounts. Each EPA Region and the states within those regions adapted the EPA protocols to meet those objectives. Today every state and territory of the US is required to have a program of aquatic toxicology testing in place. As one of the premier aquatic toxicology laboratories in the Mid-Atlantic, our experts have been providing bioassay services to wastewater clients in support of the Clean Water Act (CWA) since 1987. We have a long history of helping clients meet their compliance requirements and solving problems for those who have toxicity issues.

Consulting: With more than 25 years of experience, our knowledgeable and credible scientists can be called upon to help determine and solve toxicity issues. Credentials: As a NELAC-accredited laboratory, we have the ability to perform tests in any state participating in the NELAP program. In addition, we maintain certifications or approvals in states that do not participate in the NELAP program. Permit Review and Regulatory Compliance: We are able to provide assistance in order to effectively interpret state and federal waste discharge compliance requirements. In-house Cultures: The majority of the organisms we test with are cultured within our facility. This ensures a continuous and reliable supply of healthy organisms for testing. Fast and Accurate Results: All of our data goes through peer and internal QA/ QC checks prior to being submitted to the client. Reports are custom designed to meet client’s requirements for internal and regulatory reporting. We also employ the latest statistical software to calculate endpoints precisely. Even with these layers of review and custom designed reports, our TAT is typically less than one week.

Aquatic Toxicology is an analysis which studies the adverse effects of chemicals on aquatic organisms. These organisms are subjected to varying concentrations of an aqueous solution to determine if lethal or sub-lethal effects are observed. Bioassay tests can also be applied to soil and sediment materials with plant and terrestrial invertebrate species.
Our Capabilities
•
Field sampling
We offer a broad range of aquatic toxicology testing including the design of client-specific test protocols required to satisfy CWA specifications and other nonwastewater needs.
•
Completely customized testing
Our testing capabilities include: •
Acute and Chronic Whole Effluent Toxicity testing with freshwater and marine species
•
Sediment/Soil Assays
•
Toxicity Identification Evaluations (TIEs)
•
Chlorophyll a analysis
•
Water Effect Ratios (WERs)
•
Pure compound testing.
•
Stream surveys (biological/chemical) for impact and eutrophication studies
All testing is conducted in our stateof-the-art facility designed specifically for aquatic toxicology testing. All of our aquatic toxicology tests are performed in accordance with USEPA methods. If required, customized protocols are employed for non-wastewater sources to comply with other regulatory agency requirements. Our culture laboratory consists of systems designed for the purpose of breeding healthy organisms with genetic traceability. Monthly Standard Reference Toxicant (SRT) tests are performed on all organisms cultured in house. Concurrent SRT tests are performed on organisms brought in from outside culture laboratories. All SRT data is graphed and evaluated for consistency.
