HC Deb 20 November 2003 vol 413 c1241W
Mr. Gummer

To ask the Secretary of State for Environment, Food and Rural Affairs what steps she is taking to(a) reduce levels of synthetic oestrogen in river water and (b) prevent the metamorphosis of male fish arising from high levels of synthetic oestrogen. [140241]

Mr. Morley

The Environment Agency published research findings in 2002 on the effects of oestrogens on aquatic life. A summary of the research findings is available in the Library of the House. My officials are currently discussing, with the water industry, the Office of Water Services (Ofwat) and the Environment Agency, a proposal for a collaborative demonstration programme aimed at assessing the cost-effectiveness of sewage treatment processes for the removal of synthetic oestrogens from sewage.
