Your water at a glance
Moderately hard water. Know your mineral level.
This figure helps you choose appliance settings. Hardness describes dissolved minerals and does not establish whether every water-quality requirement was met.
197 mg/l as CaCO₃
Converted from 78.825 mg Ca/l (total hardness expressed as calcium) × 2.5 = 197.0625 mg/l as CaCO₃, shown rounded to the nearest whole mg/l.
Soft ≤100 · Slightly hard ≤150 · Moderately hard ≤200 · Hard ≤300 · Very hard >300 mg/l. DWI hardness bands; not safety grades.

Drinking-water results
What do the important results mean?
Read the status, sample range and source requirement together. A low average can hide an individual exceedance. Green labels mean the supplier reported no exceedances for that parameter and period; amber calls for source context.
Iron
! Exceedance reported in this period
Published mean
<118.22 μg Fe/l

Official supplier help ↗Taste, appearance and mineral content
Chlorine, pH and minerals answer different questions. Calcium and magnesium help describe hardness; chloride is different from treatment chlorine. None is a stand-alone water-quality score.
Free chlorine residual
Disinfectant remaining after treatment. It can influence taste and smell; a lower concentration is not automatically better.
See the measurement and context ↓Total chlorine residual
Disinfectant remaining after treatment. It can influence taste and smell; a lower concentration is not automatically better.
See the measurement and context ↓pH
Describes acidity and alkalinity on a scale, rather than an amount of a substance. Where the source gives a range, both its lower and upper bounds matter.
See the measurement and context ↓Calcium
A naturally occurring mineral that contributes to hardness. Calcium alone is not the same measurement as total hardness.

Every result retains its original units, range, sample count and source notes. Comparisons use the reference printed in this report; qualitative references and missing limits are not converted into invented pass/fail judgements. Unlisted substances are not necessarily absent from the water.
Parameters without their own explanation: A substance monitored in this supplier report. The source reference, units, sample range and any reported failures provide its context; the number alone is not a water-quality rating.
Source note on 119 of these parameters: “Source also reports 0 failures (0.00%) against its undertaking standard. Qualified values are taken at face value in the supplier's calculations.”
A failure count (under “Original wording and source notes”) supports a pass/fail label only where the report gives an applicable limit for that parameter.

Official supplier report for this supply zone, retrieved with postcode YO51 9AR. Town pages that cite this zone show their own supplier-confirmed example postcode. This is an example supply area, not a measurement at every address in the towns it serves.
Annual report period is read from the PDF, separately from any year in the zone name. Total hardness is converted using Yorkshire’s factor of 2.5 from mg Ca/l to mg/l as CaCO₃.
All published numeric parameters are retained, including censored readings and historical failures. These results are not a statement about current incidents.
Unit conversion of supplier total hardness: original mean 78.825 mg Ca/l, range 24.1–116 mg Ca/l. Yorkshire's own converter multiplies total hardness expressed as calcium by 2.5 for calcium-carbonate equivalent. This is not the separate calcium concentration.
Hardness: 8 samples · reported range 60.25 to 290 mg/l as CaCO₃.
Yorkshire total hardness expressed as calcium is converted to calcium carbonate using the supplier’s factor of 2.5. The separate calcium measurement is not total hardness.
Status labels describe the published parameter and period. Historical exceedances do not automatically establish a current incident. Numerical limits are taken from the original report, not applied indiscriminately across countries, dates or sampling locations. DWI explains how standards work in England and Wales.
