These are historical public-supply monitoring records, not a current water notice or a test of every household. Sampling locations can be outside the linked towns.

What do the latest results show?

The latest year is 2025. Results and listed exceedances are counted separately from their respective datasets.

  1. In 2025, 7,507 Taste monitoring results were recorded from 7,507 samples across 711 public water supplies.
  2. The separate EPA exceedance dataset lists 0 records across 0 schemes in 2025.
  3. There were 744 more monitoring results than in 2024 (11.0% more). This describes the volume of monitoring, not a change in water quality.

Taste records and consumer acceptability

Recorded results for 2025, with official requirements shown separately.

Irish drinking-water requirement

A qualitative requirement

Consumer-acceptable taste with no abnormal change; no single numerical concentration limit.

This is separate guidance, not a test result for your own water. It does not reclassify historical records.

These are historical records, not the current status of your water. EPA-listed exceedances come from a separate dataset.

The legal requirement is qualitative: acceptable to consumers with no abnormal change. Numeric storage of a taste record does not make it a concentration measurement.

Monitoring measurement units are not verified, so these recorded values cannot be compared with the official standard. Units in the listed exceedance table are reproduced separately from that source.

How to read these results

Measurement coverage · 2021–2025

The imported monitoring records have no unit field. These are counts of recorded values, not concentrations or a comparison with the standard.

21,018 numeric records; 6 censored text records; 15,056 other text-only records; 214 records without a result value.

35,497 records have a non-empty text field, including records that also have a numeric value. This overlapping field count must not be added to the numeric total.

EPA-listed Taste exceedances

3 listed records across 3 distinct schemes, 2021–2025. These are historical sample records, not a current assessment of each property in a supply zone.

Results and limits below are reproduced from the separate EPA exceedance dataset, with its own reported units. These units are not assigned to the wider monitoring dataset.

Places with mapped Taste monitoring data

Explore existing place reports with mapped Water Supply Zones containing Taste monitoring records in 2021–2025.

95 published places have at least one qualifying mapped zone. The 20 largest are listed below by Census 2022 population, not by Taste levels.

Places can share the same Water Supply Zone. These links do not represent independent city measurements; sampling locations may be outside the named Built Up Area. National totals above count each source record once.

Taste is not a safety verdict

The legal requirement is qualitative: acceptable to consumers with no abnormal change. Numeric storage of a taste record does not make it a concentration measurement.

Current water information for your address

For current supply information, check your Eircode with Uisce Éireann. Follow the notice for your address: a Boil Water Notice and a Do Not Consume Notice have different instructions. This historical report does not recommend boiling as a treatment for chemical parameters.

Frequently asked questions

What does this Taste report cover?

36,294 monitoring records across 5 available monitoring year(s): 2021, 2022, 2023, 2024, 2025. The selected source is Taste. National totals come directly from EPA records, not a sum of towns.

What is the Irish drinking-water requirement for Taste?

A qualitative requirement. Consumer-acceptable taste with no abnormal change; no single numerical concentration limit.

Can these records prove water is safe by taste?

No. This page reports a historical taste parameter and does not infer safety from taste or from the absence of a listed record.

Can I compare the recorded Taste values with the standard?

Monitoring unit metadata have not been verified in this import. Numeric and censored records are counted separately; no concentration median, maximum or compliance rate is inferred from them. Listed records keep the units supplied by the separate EPA exceedance dataset.

Does a place link give the current Taste result at my address?

No. It identifies a place with a mapped supply and historical monitoring. It is not a test of every property. Check current Uisce Éireann supply information using your Eircode.

Sources and methodology

Monitoring data
EPA Ireland: drinking-water monitoring data: public-supply monitoring results and the separate listed exceedance records, 2021–2025.
Counting
Source records are counted once across schemes. A sample is identified by its scheme, sample ID and date. Listed exceedances are not inferred from numeric results.
Interpretation
Text and censored results are not converted to numbers. Missing values are not zero. Records do not establish conditions in an individual home or an official compliance rate.
