Oxford has hard water with a hardness level of 279 mg/l CaCO₃.
Based on data provided by sources like ScaleGuard, Oxford's water is classified as 'Hard water'. The specific measurement given is 279 milligrams per litre (mg/l) of Calcium Carbonate (CaCO₃). This level falls within the range typically defined as hard water.
Here's how Oxford compares to some other UK locations mentioned in the reference:
| Town / City | Water Hardness Level | Mg/l CaCO₃ |
|---|---|---|
| Guildford | Hard water | 238 |
| Oxford | Hard water | 279 |
| Hemel Hempstead | Very hard water | 303 |
| Milton Keynes | Very hard water | 308 |
As you can see from the table, while Oxford has hard water, it is not classified as 'Very hard water' like Hemel Hempstead or Milton Keynes, which have higher CaCO₃ levels.
Understanding Hard Water
Water hardness is primarily determined by the concentration of dissolved minerals, mainly calcium and magnesium ions. High concentrations of these minerals lead to hard water.
- Hard Water: Contains a significant amount of dissolved minerals.
- Soft Water: Contains fewer dissolved minerals.
The level of hardness can impact various aspects of daily life, such as:
- Lathering: Soap lathers less effectively in hard water.
- Scale Buildup: Minerals can deposit as scale in pipes, kettles, and appliances.
- Taste: Some people notice a difference in taste.
For residents of Oxford, the 'Hard water' classification means they may experience typical issues associated with mineral deposits, such as limescale, particularly in areas where water is heated.
