Discharges into the aquatic environment of contaminated wastewater from industry, domestic sewage and stormwater, represent major sources of aquatic pollution. The complex nature of these wastewaters makes assessment of their potential biological impact difficult. Whole effluent toxicity testing (WETT) has been widely used overseas to assess the potential toxicity of effluents. The results of these tests can be used for a variety of functions including resource consent monitoring and compliance, toxicity identification evaluations, and evaluation of effluent treatment processes.
