This is our descriptive frequency: listed exceedance records divided by result records, multiplied by 1,000. It is not an official EPA compliance rate. Differences in sampling volume and parameters tested affect comparisons. A missing denominator is shown as unavailable.

Common questions
Frequently asked questions
Is Kinsale tap water safe to drink?
WaterCheck Ireland does not issue a current safe or unsafe verdict. This page presents historical monitoring data. Check Uisce Éireann for any current Boil Water or Do Not Consume notices affecting your address.
Can you drink tap water in Kinsale?
WaterCheck Ireland provides historical drinking-water monitoring data, not a current safe or unsafe verdict. For current Boil Water or Do Not Consume notices, check your Eircode with Uisce Éireann.
What is the tap water quality in Kinsale?
In 2025, monitoring data for the Water Supply Zone mapped to Kinsale included 686 results across 70 parameters. The separate EPA-listed exceedance dataset contains 0 records for those zones in 2025. These figures summarise historical records and are not a current safety verdict.
Who monitors drinking water quality in Kinsale?
The historical monitoring figures shown here come from drinking-water datasets published by the Environmental Protection Agency (EPA), Ireland. Uisce Éireann operates public water supplies and publishes current supply notices.
What is a Water Supply Zone?
A Water Supply Zone is a defined area supplied by a public drinking-water system. Monitoring records apply to the zone as a whole, so sampling locations can be outside the Census Built Up Area.
What does a listed exceedance mean?
It is a record published in the separate EPA exceedance dataset. WaterCheck Ireland reproduces those records and does not infer additional exceedances or turn the record count into a safety assessment.
How can I check current water notices for my Eircode?
Use your Eircode on the Uisce Éireann website to check current Boil Water and Do Not Consume notices. This page is based on historical monitoring data and is not a live notice service.

How this page is made
Sources and methodology
- Settlement
- Census 2022 Built Up Area: Kinsale. Population refers to the whole Built Up Area.
- Supply mapping
- Uisce Éireann Water Supply Zone boundaries are matched geographically to the settlement.
- Monitoring
- EPA monitoring results and the separate listed exceedance dataset, 2021–2025.
- Interpretation
- Geographic overlap measures land area, not population served; monitoring applies across the full supply zone.
