Saltwater Testing Methods

Whole Effluent Toxicity (WET) tests were developed as a tool to evaluate the potential harmful effects of effluent discharged into surface water. Carefully chosen indicator organisms are exposed to whole effluent and/or effluent dilutions for a specified period of time to observe the effluent's effect on the organisms and its potential to effect organisms in the receiving stream. Test methods and duration of the tests are specified in the discharger's permit. 

Whether you are a waste water treatment plant, chemical plant, refinery, or product manufacturer, contact us to discuss your permit or research needs.
