What Makes Newark on Trent's Water Unique?

Local geology and source profile

Source: MixedTDS: 259 mg/LpH: 7.8

Severn Trent Water plc serves Newark on Trent, a town situated in Nottinghamshire within the East Midlands. The water supply here comes from a mix of sources, primarily the River Trent and groundwater drawn from the Sherwood Sandstone aquifer. Water undergoes treatment at regional facilities before reaching consumers throughout Nottinghamshire. Newark itself lies within the Trent Valley watershed, an area characterized by specific geological underpinnings.

The geology beneath Newark on Trent features Triassic-age Mercia Mudstone and Sherwood Sandstone formations. Groundwater tapped from the Sherwood Sandstone aquifer is moderately mineralised, a characteristic influenced by its interaction with overlying clay and marl deposits. This geological makeup is key to understanding the water's composition as it travels from source to tap.

Homeowners in this moderately hard water area might notice some limescale forming in appliances like kettles and heating systems over time. You may find that washing machines and dishwashers need a bit more detergent to work effectively. Shower heads and taps can develop mineral deposits, too. While not strictly necessary, installing a water softener could be beneficial if you're particularly bothered by scale or want to maximize the efficiency of soaps and detergents and potentially extend the life of your appliances. For specific details on lead, copper, PFAS, or pH levels, reaching out to Severn Trent Water directly or checking their online postcode tool is the best approach.

Geology & Source: Mercia Mudstone and Sherwood Sandstone; aquifer contact with clay/marl causes moderate mineralisation
