Press Release: Cyanobacteria On The Increase?


Levels of cyanobacteria – or ‘blue-green algae’ as its commonly known – are massively on the increase in our lakes, a frightening finding as UK water treatment plants – those that deliver your tap water – do not routinely test for it even though it’s a neurotoxin linked to the development of Alzheimer’s and Parkinson’s disease.

Cyanobacteria is toxic. Acute exposure causes skin irritation, gastroenteritis and respiratory symptoms; chronic exposure in low-doses over a number of years can result in liver tumours, hormone disruption and neurodegenetive disease.

A 58% rise has been seen over the past 200 years in lakes across the UK including the Lake District, the West Midlands, Scotland and Northern Ireland due to rises in industrial pollution. (Ecology Letters.)

Cyanobacteria accumulations can be seen on waterways as a blue-green bloom. It’s deadly to animals so keep your pets away from it. It can’t be seen or tasted in tap water, so there’s no way of knowing if you are drinking it or not. The old adage rings true: better safe than sorry.

The slug pesticide metaldehyde has also been found in tap water at levels breaching UK standards, and water treatment plants cannot remove it.

So is it time to look into alternatives to tap water to hydrate safely for your health, fitness and wellbeing?

There are many bottled water brands on the market, but studies show the RODI (Reverse Osmosis with De-Ionisation) purification process produces the purest water possible. It’s also environmentally responsible, achieving a 95%+ lower carbon footprint compared to drinking bottled water.

A RODI purifier typically fits under the kitchen sink. It automatically ‘cleans’ tap water, resulting in 99.99% pure water across the spectrum of man-made and unavoidable impurities. The pure water is delivered through an unobtrusive small tap fitted in your existing kitchen sink (although the Quatreau tap system which delivers RODI pure water as boiling, chilled, sparkling and hot/cold from a single, touch-screen tap, is also available). Both the RODI purifier and the taps can be retrofitted.
