§ Dr. CunninghamTo ask the Secretary of State for the Environment if he will make a statement on algae blooms both in Britain's reservoirs and lakes and in estuaries and around the coastline.
§ Mr. Chris Patten[holding answer 19 October 1989]: Algal blooms are normal in United Kingdom surface waters. In the particular cases of toxic blue-green algae in reservoirs this summer it has been prudent for owners to prohibit public access for recreational uses. The incidence of blue-green algae is now declining. The National Rivers Authority is monitoring the situation closely.
