Your water at a glance
Very hard water. Expect limescale.
For your home, the main practical issue is mineral scale in kettles, showers and appliances. Check your dishwasher setting and follow appliance care instructions.
371 mg/l as CaCO₃
Converted from 148.375 mg Ca/l (total hardness expressed as calcium) × 2.5 = 370.9375 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.
E. coli
✓ No exceedances reported
Published mean
0 no'/100 ml
Source reference: 0 no'/100 ml
A microbiological indicator. The reported sample results and any failures matter more than an average bacterial count.
72 samples · Range: 0 to 0 no'/100 ml
The source reports 0 failures across 72 samples. This describes the published period.
Lead
✓ No exceedances reported
Published mean
0.579 μg/l
Source reference: 10 μg/l
Plumbing can affect lead at an individual tap. An area average cannot rule out a problem with pipes at your property.
8 samples · Range: 0.27 to 1.55 μg/l
The source reports 0 failures across 8 samples. This describes the published period.
Nitrate
✓ No exceedances reported
Published mean

Fluoride
✓ No exceedances reported
Published mean
0.112 mg F/l
Source reference: 1.5 mg F/l

For a new taste, smell, colour or supply problem, check current supplier advice. Annual data is not a live incident feed.
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 HU1 2AA. 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 148.375 mg Ca/l, range 143–154 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 357.5 to 385 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.

Is the water in Kingston upon Hull hard or soft?
Very hard. Yorkshire Water’s 2024 report gives total hardness of 371 mg/l as calcium carbonate (converted from 148.375 mg Ca/l) for the Hull Central West 2024 supply area (“2024” is part of the zone name, not the report date). That is the area returned for the example postcode HU1 2AA; supply can differ by address, so check your full postcode.
Who supplies water in Kingston upon Hull?
Yorkshire Water supplies the example postcode HU1 2AA (Hull Central West 2024 supply area; “2024” is part of the zone name). Other addresses may differ: check your full postcode or use Yorkshire Water’s water quality information.
Do I need a water softener in Kingston upon Hull?
At 371 mg/l as calcium carbonate, above the 300 mg/l threshold for very hard water, limescale in kettles, showers and appliances is the main household issue. That is about 20.8 °dH or 26.0 Clark degrees, units many appliance manuals use, so check your dishwasher setting. A softener is a household choice, not a requirement; check what a filter or softener actually does before buying.
How up to date is the water information for Kingston upon Hull?
Hardness and water-quality results both come from Yorkshire Water’s 2024 annual report. These are area summaries, not live tests of your tap; see the original Yorkshire Water report.
