Barton upon Humber Water Hardness & Quality Report (2026)

Anglian Water supplies Barton-upon-Humber, the historic north Lincolnshire market town on the south bank of the Humber Estuary — a town with a remarkable Saxon church (St Peter's), the Humber Bridge (visible from the town), and a heritage from its medieval importance as the principal ferry crossing point of the Humber before the bridge era — from the Lincolnshire Limestone (Jurassic) and Chalk (Cretaceous) aquifer system of the Lincolnshire Wolds in the north Lincolnshire Humber distribution zone, treated at Elsham Water Treatment Works near Brigg. At 206.5 mg/L (14.5°Clark), Barton-upon-Humber's water is hard — reflecting calcium contributions from the productive Lincolnshire Limestone (Jurassic Inferior Oolite) and Cretaceous Chalk aquifers of the Lincolnshire Wolds that supply the north Lincolnshire distribution zone.

Barton-upon-Humber lies in the north Lincolnshire low plain adjacent to the Humber where Anglian Water draws from the Lincolnshire Limestone (Jurassic Oolitic Limestone) and Chalk boreholes of the Lincolnshire Wolds to the south. These productive Jurassic and Cretaceous limestone aquifers deliver calcium carbonate-rich groundwater producing 206.5 mg/L with TDS 562.8 mg/L — hard water with a somewhat elevated TDS/hardness ratio (2.72) consistent with sulphate contributions from the Lincolnshire Limestone sequence and overlying Oxford Clay in the north Lincolnshire supply zone.

At 206.5 mg/L, limescale is a persistent household challenge in Barton-upon-Humber. Kettles should be descaled monthly. The combi-boiler benefits from a fitted scale inhibitor and annual professional servicing. Washing-up liquid requires more product per wash. Taps and shower heads develop visible white limescale deposits within one to two weeks; a fortnightly wipe with white vinegar or a proprietary descaling product keeps fittings clean. The hard Lincolnshire Limestone supply at Barton reflects the broad oolitic limestone belt of the east Midlands — the same productive Jurassic limestone formation that built the great Lincoln Cathedral also mineralises the tap water on the south bank of the Humber.
