IT was interesting to read of the continuing campaign against the chlorination of tap water by Scottish Water (“Battle against chemicals in tap water goes to Holyrood”, The Herald, May 13).

A goodly number of years ago my local community council took up the argument when the local Loch Eck water supply was thought to be over-chlorinated, we being at the end of a supply branch.

It resulted in identifying excess magnesium and that resulted in a subsequent relining and replacement piping exercise (probably irrelevant to our concerns).

We accepted that chlorination is within regulatory parameters and that it results in making for safer drinking water from a bacteriological sense – though not entirely so.

There being no possibility of reversing this strategy, after a little bit of internet research and basic science I found that by adding ascorbic acid tablets (vitamin C), available from any health shop, it was possible to remove at least the chlorine smell and taste.
