I was really pleased to read this – I have discouraged people from swimming in the past because it is just too toxic: “It’s the bane of swimmers’ lives – but chlorine in pools may become a thing of the past. An odourless, colourless alternative called PoolSan, has had a successful 2 year trial at Leatherhead Leisure Centre, Surrey and in the US. Now, according to Celine Brown, PoolSan’s UK distributor, it is ready for widespread use. She said “It’s the end of chlorine – the smells & itches. The water is clean & everyone from pregnant women to asthmatics can go in it”. Using precious metals & natural minerals, it works through ionisation. When a slight electric current is passed through the water the minerals react to destroy bacteria. Mail on Sunday 13.7.08.
