What to Watch For
Excess calcium and magnesium affect taste and leave mineral deposits in your body over time. Linked to dry skin, hair damage, and kidney stone risk in hard water regions.
Total dissolved solids above 300 ppm indicate heavy mineral loading. High TDS affects taste, scales appliances, and suggests other dissolved contaminants may be present.
Fertilisers, pesticides, and animal waste wash into water sources from farmland. Nitrate contamination is a persistent problem in agricultural regions.
Nitrates from fertiliser runoff can exceed safe levels in groundwater-fed supplies. High nitrate intake is particularly dangerous for infants and pregnant women.
Trace levels of agricultural pesticides persist in treated water. While individually below legal limits, the cumulative effect of multiple residues is poorly understood.
Untreated sewage is discharged into rivers and water sources during heavy rainfall. These overflow events introduce bacteria, viruses, and chemical pollutants upstream of treatment intake points.
Lead leaches into drinking water from old service pipes. Even low-level exposure is linked to developmental harm in children and cardiovascular issues in adults.
Noticeable chlorine taste indicates higher-than-average treatment levels. While safe at regulated doses, it affects the flavour of drinking water, cooking, and hot drinks.
Decades-old pipe networks corrode and degrade, introducing trace metals, sediment, and bacteria into the water supply between treatment and your tap.
Tiny plastic particles found in treated water supplies pass through standard filtration. Research into long-term health effects is ongoing, but early findings raise concern.
Per- and polyfluoroalkyl substances — "forever chemicals" — persist in water indefinitely. Linked to thyroid disease, immune suppression, and increased cancer risk. Standard treatment does not remove them.
When chlorine reacts with natural organic matter in water, it creates by-products including trihalomethanes. Long-term exposure is associated with increased health risks.
Trace amounts of medicines — from painkillers to hormones — have been detected in treated water supplies. Conventional treatment does not fully remove them.
Overview
Wessex Water pulls from chalk aquifers across Somerset, Dorset, and Wiltshire — delivering hard water loaded with dissolved minerals. Your kettle knows. Your skin knows. The question is whether you know what else is in there.
Water Hardness
Wessex water is consistently hard — 200–350 ppm from chalk-filtered groundwater. Limescale builds in pipes and appliances. You're descaling monthly and replacing kettles yearly.
Common Contaminants
Agricultural land across Wiltshire and Somerset pushes nitrate and phosphorus levels close to regulatory limits. Wessex Water was fined £500,000 for sewage killing thousands of fish. Lead pipes remain in older properties. PFAS, pesticide residues, chlorine, microplastics, and pharmaceutical traces — from painkillers to hormones — are all present in treated supplies.
What Pluvia Removes
Wessex's hard water minerals, the nitrates and phosphorus from agricultural runoff, the pesticide residues, the PFAS, the lead from old pipes, the chlorine and pharmaceutical traces — Pluvia's RO reduces your TDS from 300+ to under 30 in one pass. No salt bags. No chemicals. Just pure water from chalk aquifer supply.
Regional Notes
Wessex Water sources over 75% of supply from underground aquifers. Groundwater collects contaminants over decades — what farmers sprayed 20 years ago may be reaching your tap today.
