Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what estimate his Department has made of the level of micro-plastic contamination in UK tap water.

The Drinking Water Inspectorate (DWI) has commissioned research to investigate the efficiency of microplastic removal by drinking water treatment processes. In addition, the DWI is supporting research by the water industry as a whole to measure levels in treated water in the UK.
