What these readings mean
UK drinking water is regulated under the Water Supply (Water Quality) Regulations 2016, which set a prescribed concentration value (PCV) for each substance. Anglian Water must sample against these and report the results to the Drinking Water Inspectorate.
Nitrates in Milton Keynes
25.04 mg/L·UK limit 50 mg/L
Nitrates come mainly from agricultural fertiliser and sewage reaching groundwater. Healthy adults process them without difficulty; the limit exists principally to protect bottle-fed infants under six months.
Lead in Milton Keynes
— µg/L·UK limit 10 µg/L
Water leaves the treatment works lead-free. Any lead is picked up from the pipework between the main and your tap, so the reading depends heavily on your own property — pre-1970 homes are the ones worth checking.
Fluoride in Milton Keynes
— mg/L·UK limit 1.5 mg/L
Occurs naturally in some groundwater and is deliberately added in a minority of UK supply areas. Around 10% of England receives a fluoridated supply.
Chlorine in Milton Keynes
0.39 mg/L·UK limit no statutory limit
Added as a disinfectant and required to remain present through the network to keep water safe in transit. Typically 0.2–0.5 mg/L at the tap. A noticeable taste is usually harmless and fades if water stands in a covered jug.
Living with hard water in Milton Keynes
At around 350 mg/L CaCO₃, Milton Keynes sits firmly in the hard water band. Hardness is dissolved calcium and magnesium picked up as water passes through chalk and limestone. It is not a health risk — the minerals are the same ones found in food — but it has practical consequences.
- Limescale. Kettles, showerheads and heating elements scale up faster. Descaling every few months keeps appliances efficient.
- Skin. Some people with eczema find hard water aggravates symptoms, though the evidence on softeners as a treatment is mixed rather than settled.
- Soap and detergent. Hard water needs more of both to lather, which is why dishwasher salt exists.
