Toxicity consenting project nears completion

A collaborative programme between industry and the Environment Agencies demonstrating how toxicity assessment could be used for consenting effluent discharges is due to conclude next March. The final projects include a "toxicity identification evaluation" of discharges to Northumbrian Water's Bran Sands sewage treatment works and a modelling exercise demonstrating the dispersion of effluent toxicity in the Tees estuary.
