Whole Effluent Toxicity Testing
Whole Effluent Toxicity (WET) refers to the aggregate toxic effect to aquatic organisms from all pollutants contained in a facility’s wastewater (effluent). It is one way we implement the Clean Water Act’s prohibition of the discharge of toxic pollutants in toxic amounts. WET tests measure wastewater’s effects on specific test organisms’ ability to survive, grow and reproduce.
The WET methods listed below are specified in 40 CFR 136.3, Table I A. WET test methods consist of exposing living aquatic organisms (plants, vertebrates and invertebrates) to various concentrations of a sample of wastewater, usually from a facility’s effluent stream. WET tests are used by the National Pollutant Discharge Elimination System (NPDES) permitting authority to determine whether a facility’s permit will need to include WET requirements.
