select your favourite empty, then turn on your kitchen tap to reveal a miraculous source of potable water that is 500-1000 times cheaper than the bottled variety, and subject to much tighter regulations
I was recently given a free bottle of Highland Spring water when I walked past the VisitScotland shop in London. On the bottle it clearly states that re-use is not recommended because of the risk of bacterial growth [I paraphrase].
Most sources on the internet currently seem to support this idea, however a few minutes on google can actually turn up evidence in favour of washing and refilling. If it’s not safe to re-use bottles, then presumably it should not be safe to re-use mugs or glasses either – and you don’t necessarily drink directly from the bottle. [There is also a concern about potentially carcinogenic plasticiser migration from well-used bottles, so only PET bottles should be re-used.]
The idea of buying water has always seemed slightly odd, when we live in a country where it falls out of the sky on such a regular basis. On the other hand, having seen the soot-soaked raindrops that sometimes fall on my laundry, I’m not totally prepared to drink it neat.
We have a well in our back garden, but we’ve never tried the water. Instead we use tap water and a brita filter. After all, we already pay for the water that comes through our taps, and the added health benefits of natural mineral water are as dubious as the claims that it is organic.
