Do You Have London's Hardest Water?
We’re now over a month into the UK’s coronavirus lockdown and it’s safe to say we are becoming more house proud than ever before. Instagram has become a hotbed of home renovations, makeshift DIY projects and showcases of cleaning prowess (probably because we’re all running out of things to do!).
Spending so much time at home for many has allowed us to take stock and review the places we live, and question whether our properties that we’re spending 24 hours a day are fulfilling our needs. This means that residents are beginning to take notice of small bugbears that need fixing that would usually go unnoticed in the trials of ‘normal life’.
How are Londoners handling the lockdown?
For those in London living in smaller spaces, you can understand why the restrictions of the lockdown might be harder compared to other areas of the UK. The temptation to sit on the sofa most of the day and put any sort of fitness regime on hold might be inviting, however there has never been a more important time to put your health first, with hydration being key!
With trips to the supermarket restricted, we have never been so reliant on the basics of tap water to stay hydrated. However, it’s no secret that the taste (and even appearance) can vary dramatically depending on where in the UK you are based.
What is the state of London’s water?
The majority of London itself is supplied by Thames Water, however the hardness level itself is typically dictated by a number of geographical factors, most notably when water percolates through deposits of limestone or chalk which is largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.
However, a number of other water suppliers including Essex & Suffolk Water, Affinity Water and South East Water are also responsible for certain regions towards the outer zones of the city.
Does the hardness vary throughout the capital?
It does indeed! While London has some of the hardest water in the UK, the severity of hardness does vary across the city and we wanted to find out where in the capital had the hardest water. And what better way to display our findings? With a London Underground hard water map of course.
The results below are based on parts per million (ppm) readings which measures the severity of water hardness. Readings of over 200ppm suggest that the water supply should be considered hard.
Epping (CM16) - 370ppm High Barnet (EN5) - 347ppm Holloway Road (N7) - 338ppm Cockfosters (EN4) - 337ppm Edgeware (HA8) - 335ppm Arnos Grove (N11) - 333ppm Stanmore (HA7) - 332ppm Rickmansworth (WD3) - 332ppm Tottenham Hale (N17) - 332ppm Lancaster Gate (W2) - 330ppm
