Concern was expressed at the potential impact of endocrine disrupting substances (EDSs) on wildlife. Within England and Wales, the Environment Agency Regulator proposed an approach to taking action - Endocrine disrupting substances in the environment: The Environment Agency's strategy 2000.
A particular area of concern was the reported effects of discharges from sewage treatment works on freshwater fish. Requirements for further or improved sewage treatment could have major implications for future capital investment by the Water Industry.
A team led by WRc with the Centre for Ecology & Hydrology, WRc-NSF and Brixham Environmental Laboratory undertook research funded by the UK Water Industry Research (UKWIR). The project examined:
- What was known about the removal of EDSs through sewage treatment processes?
- What was the potential cost burden to society of additional controls on sewage effluent discharges?
- Improved understanding of the removal of EDSs by sewage treatment processes and identified requirements for future research
- A better understanding of the potential cost implications of improved removal assisted the Water Industry in planning future capital investment.
