Estimated

Estimated: Hard (~250 mg/L CaCO₃)

Based on typical regional geology in Dorset (often limestone or similar). Lab-tested data for this specific supply zone is not yet available.

Your area is likely to have hard water. This can affect skin conditions and cause limescale buildup.

Parents: nitrate levels are elevated

Consider a filter rated for nitrates when preparing infant formula, and follow NHS guidance on boiling water.

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. Your Area must sample against these and report the results to the Drinking Water Inspectorate.

Nitrates in Bournemouth

30.81 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 Bournemouth

0.63 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 Bournemouth

0.09 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 Bournemouth

0.50 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 Bournemouth

At around 250 mg/L CaCO₃, Bournemouth 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.
