Scottish Water · Supply area: Ardeonaig
Published water hardness
9.95mg/l as CaCO₃
Soft
Hardness reporting period: 2024
Scottish Water calculates this annual hardness from its calcium and magnesium measurements. We show the supplier’s published figure. Sample counts and ranges are not provided in the hardness table.
This result describes dissolved minerals. Use your appliance manual for settings and care instructions. Hardness is not a health or safety score.
0.10 mmol/l
A conversion of the published hardness, not another test. Follow your appliance’s model-specific instructions.
Has the hardness changed?
History for this reported source area. Only comparable annual statistics appear in the chart; rolling summaries are kept separate. These are not daily tests at your address.
Scroll the chart sideways on smaller screens, or read the values below. Vertical axis: hardness in mg/l as CaCO₃. Bars show annual means.

Historical figures come from retained source copies. Supplier links may now open a newer edition. Ranges describe the samples reported, not confidence intervals. A short annual series supports a comparison; it does not establish a sustained trend or a change at your tap.

Scottish Water publishes annual average calcium and magnesium and hardness calculated from those measurements. We retain the supplier’s hardness value without recalculating it.
This is a hardness dataset, not a complete water-quality report. No missing chemical, microbial or compliance values are inferred.
History is grouped by the exact published supply-zone name. Different names are not merged. Boundaries and the supply serving an individual address can change; this series does not establish a historical postcode match.
The latest available hardness edition in the catalogue checked on 6 September 2026 is 2024. A later quality report can cover a different period. Original PDFs are retained privately; the supplier link is the primary reference.
