The EPA Drinking Water Report for Public Water Supplies 2019 provides an overview of drinking water quality in Ireland for 2018, based on monitoring data from Irish Water, and the regulation of public supplies by the EPA.
The EPA Focus on Private Water Supplies 2018 report provides an overview of both the quality and enforcement of private drinking water supplies in Ireland for 2018, based on monitoring and enforcement data from 28 local authorities.
The EPA has identified the most important issues which should be addressed on a national level to protect and improve public drinking water supplies. Recommendations have been made by the EPA to Irish Water to address these issues and work is progressing.
|Priority Issues||Required Actions|
|Ensure all water treatment plants are effective||Irish Water have prepared action programmes, with completion dates, for all public water supplies on the EPA’s Remedial Action List. Irish Water should continue to progress the action programmes to make sure completion dates are met.|
|Keeping water free of harmful bacteria (disinfection)||To prevent people from needing to boil their water, Irish Water should continue to upgrade their disinfection systems under the National Disinfection Programme|
|Minimising harmful disinfection by-products (trihalomethanes)||Irish Water are working to ensure treatment systems are in place to remove as much natural matter (rotting vegetation) as possible from drinking water sources to prevent the formation of trihalomethanes|
Eliminate lead from our waterpipes
|Public bodies should assess public buildings (schools, hospitals, libraries) for lead pipes and fittings and replace any lead pipework found. Private home owners should be encouraged to replace lead pipework in their homes or businesses.|
|Prevent pesticides from entering our waters||Irish Water are working with other responsible organisations to protect drinking water sources from contamination with pesticides and promote responsible use of pesticides. The Department of Agriculture, Food and the Marine authorises pesticides for use in Ireland|
|Manage risks to our public water supplies||To ensure a safe supply of drinking water, Irish Water have started to prepare a Drinking Water Safety Plan for every public water supply. This involves identifying all the risks in a supply and outlining actions to avoid or reduce the risks.|
Owners of private wells should ensure that they are designed, located, installed and maintained properly. Wells should be tested regularly, particularly after a prolonged period of heavy rainfall, since this is when the well may be overwhelmed and contaminated.
