Water Supply: Pollution
The question
To ask the Secretary of State for Environment, Food and Rural Affairs, what steps his Department is taking to monitor the presence of (a) antidepressants, (b) contraceptives and (c) other over-the-counter medications in the water supply.
Answered by Emma Hardy
Water companies are required by law to assess and manage risks to drinking water quality, including those posed by pharmaceutical substances such as antidepressants, contraceptives and over-the-counter medications. Where a risk is identified, appropriate monitoring and treatment processes must be in place to ensure the safety of drinking water.
The DWI has commissioned research and monitoring to assess the presence of pharmaceuticals in source and treated waters. This includes a toxicological evaluation and targeted monitoring studies, which have concluded that levels found, where detectable, are extremely low and do not pose an appreciable risk to human health.
The Department continues to monitor emerging scientific evidence and works with expert bodies including the UK Committee on Toxicity and the World Health Organization to ensure that drinking water standards remain protective of public health.
