§ Mr. RedmondTo ask the Secretary of State for the Environment if he will list by(a) location and (b) water authority the sites that suffered from toxic pollution due to blue-green algae, caused by phosphates and nitrogen from sewage and farming entering public reservoirs; and if any successful prosecutions have been made.
§ Mr. Heathcoat-AmoryThere were 53 sites in England where blooms of toxic blue-green algae were identified in 1989. The causes of the blooms have not yet been determined, but the National Rivers Authority is investigating the issue.
