Aquatic Toxicity Testing
EnviroScience, Inc. - Bioassay Laboratory Laboratory

The aquatic toxicology laboratory at EnviroScience conducts superior testing for municipal, industrial, and private sector clients. Operational seven days a week, the laboratory provides flexible scheduling, comprehensive sampling, expert consultation, and timely reporting. Quality assurance 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) Testing, 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. Aquatic test organisms are subjected to varying concentrations of wastewater, under controlled laboratory conditions. Toxicity levels are determined by statistical analysis.
