Water: Health Hazards
The question
To ask the Secretary of State for Environment, Food and Rural Affairs, whether she plans to publish updated guidance on incorporating (a) blue-green algae and (b) other additional public health factors into bathing-water quality assessments.
Answered by Emma Hardy
The purpose of the Regulations is to ensure the protection of public health through the use of monitoring and classifications. Bathing waters are one of the most visible ways in which the public interacts with the water environment and so it is critical that appropriate regulations meet the needs of water users and those involved with managing bathing water sites.
On 28 October 2025, the Department laid before Parliament an SI which incorporates reforms to modernise the Bathing Water Regulations. Coming into effect on 21 November 2025, these reforms include the scope to extend the bathing and monitoring season from 21 November 2025. We will continue to evaluate environmental and societal impacts of future reforms and engage stakeholders as we move to implementation.
Current guidelines on Environment Agency and Local Authority roles during pollution incidents, including blue-green algae, remain valid.
