Operational seven days a week, the EnviroScience Bioassay Laboratory provides flexible scheduling, comprehensive sampling, expert consultation, and timely reporting. Quality assurance within the laboratory is achieved through strict adherence to guidelines established by state and federal regulatory agencies, in-house culturing, and a dedicated staff.
Aquatic toxicity tests, also known as bioassays or Whole Effluent Toxicity (WET) Tests, are used to monitor the toxicity of discharge waters. Bioassays are a cost-effective evaluation of potential environmental impacts and provide a measure of the interaction between constituents in a wastewater discharge and the body of water into which it discharges. Aquatic test organisms are subjected to varying concentrations of wastewater under controlled laboratory conditions. Toxicity levels are determined by statistical analysis.
