What is the Remedial Action List? 

The Remedial Action List (RAL) is a register of public water supplies that are in need of corrective action. The EPA requires Irish Water to complete an action programme for each supply on the list. When Irish Water has shown that the issue has been fixed, a supply can be removed from the list. The EPA updates the Remedial Action List twice per year.

How many public water supplies are on the Remedial Action List? 

The first Remedial Action List in 2008 identified 339 public water supplies that required corrective action. The latest remedial action list published can be found at the link above.   

Why is a public water supply put on the Remedial Action List? 

Public water supplies are added to the Remedial Action List for one or more of the following reasons: 

  • The water supply fails to meet the drinking water standards for E. coli, enterococci, trihalomethanes, pesticides, aluminium or turbidity
  • The water supply has inadequate treatment for Cryptosporidium or inadequate disinfection
  • The HSE identifies a water supply where improvements are required
  • An EPA audit identifies a lack of operational control at the water treatment plant

What can the EPA do if Irish Water fails to improve drinking water quality? 

The EPA is the drinking water quality regulator for public water supplies and ensures that drinking water supplied by Irish Water meets the standards of the Drinking Water Regulations.  The EPA can take enforcement action, including carrying out drinking water audits, issuing legally binding directions to Irish Water, and taking a prosecution against Irish Water if a direction is not complied with.
