Dear Mr Bohan,

Thank you for your reply.

Ofwat does not regulate drinking water quality, nor set any standards or conduct any monitoring of contaminants in drinking water. As such, we have no plans to collect the information you listed. Ofwat is the economic regulator for the water and sewerage sector, focussing in particular on the prices charged by the regional monopoly service providers. You can find out more about our work here: https://www.ofwat.gov.uk/ about-us/

You may find it helpful to engage the Drinking Water Inspectorate with your query. Their contact details can be found here: http://www.dwi.gov.uk/contact- us.htm

If you do make contact with the ICO, we will respond to them in any investigation in due course.
