pH in Drinking Water in Ireland
Explore EPA Ireland monitoring records, listed exceedances and historical trends for pH in public drinking-water supplies across Ireland.
pH describes how acidic or alkaline water is.

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.
- In 2025, 8,329 pH monitoring results were recorded from 8,329 samples across 711 public water supplies.
- The separate EPA exceedance dataset lists 282 records across 133 schemes in 2025.
- There were 430 more monitoring results than in 2024 (5.4% more). This describes the volume of monitoring, not a change in water quality.
pH records and the Irish indicator range
Recorded results for 2025, with official requirements shown separately.
Irish drinking-water requirement
6.5–9.5 pH units
6.5–9.5 pH units for public piped water; water should not be aggressive. Special provisions for bottled water are outside this page.
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.
pH is an indicator of water chemistry, not the amount of a pollutant. A national record count cannot establish the pH at an individual tap today.
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.
40,674 numeric records; 0 censored text records; 1 other text-only records; 1 records without a result value.
29,164 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.

Monitoring history 2021–2025
Monitoring volume and listed exceedances have separate scales. Select a year to inspect its figures.
Across this period, 40,676 results from 40,676 samples cover 757 distinct water supplies. Sample dates run from 04 Jan 2021 to 22 Dec 2025.
These are record counts, not an official EPA compliance rate. The number and selection of samples and monitored schemes can change between years.
There were 430 more monitoring results than in 2024 (5.4% more). This describes the volume of monitoring, not a change in water quality.

Places with mapped pH monitoring data
Explore existing place reports with mapped Water Supply Zones containing pH 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 pH 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.
View all places — the complete published place directory.
Reading pH as a water property
pH is an indicator of water chemistry, not the amount of a pollutant. A national record count cannot establish the pH at an individual tap today.
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 pH report cover?
40,676 monitoring records across 5 available monitoring year(s): 2021, 2022, 2023, 2024, 2025. The selected source is pH. National totals come directly from EPA records, not a sum of towns.
What is the Irish drinking-water requirement for pH?
6.5–9.5 pH units. 6.5–9.5 pH units for public piped water; water should not be aggressive. Special provisions for bottled water are outside this page.
Is pH a concentration of a contaminant?
No. It describes acidity or alkalinity. This page keeps pH records separate from metal or chemical concentration records.
Can I compare the recorded pH 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 pH 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.
- Water testing
- Uisce Éireann: drinking water tests
- 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.
