Range across supply zones: 270–292 mg/L.
Yorkshire Water supplies Goole from a network that blends reservoir, river and borehole sources, and the company links harder water in the east of the region to its borehole and groundwater supplies. Reported hardness is 279.7 mg/L CaCO₃, ranging from 270.2 to 292.2 mg/L between supply zones. The harder supply reflects borehole and groundwater sources, which pick up calcium and magnesium from the rock; it is hard to very hard water, so scale builds quickly on kettles, showers and heating elements and shortens appliance life unless treated.
UK suppliers report mg/L CaCO₃ and often Clark degrees (1 °Clark = 14.25 mg/L).

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).

FAQ
Is Goole water hard or soft?
It is very hard: 280 mg/L as CaCO₃ (16.3 gpg, 15.7 °dH). The usual bands are soft < 60, moderately hard 60–120, hard 120–180 and very hard > 180 mg/L.
Is tap water in Goole safe to drink?
Hardness is not a health issue; it is about limescale, taste and appliances. Mains water must meet national drinking-water standards. UK suppliers report mg/L CaCO₃ and often Clark degrees (1 °Clark = 14.25 mg/L).
How many grains per gallon is Goole water?
16.3 gpg, equal to 15.7 °dH, 28 °fH or 280 mg/L calcium carbonate.
What dishwasher salt setting should I use in Goole?
For 280 mg/L (15.7 °dH) check your manufacturer's table: maximum level (5–7).
Do I need a water softener in Goole?
Yes, unless you are only passing through: scale damages appliances within a few years.
