Edc demonstration programme in the UK--Anglian Water's approach

Area of Science:

• Environmental Science
• Ecotoxicology
• Water Quality Management

Background:

• Endocrine disrupting chemicals (EDCs), particularly steroid estrogens from sewage treatment works (STWs), are linked to male fish feminization (intersex).
• Industrial chemicals with estrogenic activity also contribute to these environmental impacts.
• Potential future regulations may require EDC removal to meet Predicted No Effect Concentrations (PNECs) in receiving waters.

Purpose of the Study:

• To address the lack of understanding regarding EDC removal in wastewater treatment processes.
• To collect baseline data for a national Demonstration Programme investigating EDC reduction at STWs.
• To trial and refine protocols for EDC data collection at selected sites.

Main Methods:

• Focus on the baseline data collection phase of the Demonstration Programme.
• Involves detailed analysis at 17 STWs across the UK.
• Protocol development and initial trials conducted with Anglian Water Services (AWS).

Main Results:

• Baseline data on EDC concentrations and removal efficiencies are being established.
• The study identifies technical challenges and informs the broader Demonstration Programme.
• Initial trials help refine methodologies for large-scale data collection.

Conclusions:

• Understanding EDC removal is crucial for effective environmental policy.
• The Demonstration Programme provides essential data for managing EDC impacts on aquatic ecosystems.
• Collaboration with water service companies like AWS is key to program success.
