Qual­ity as­sur­ance

Cape Times - - OPINION -

MARK Bratj­man’s “Well qual­ity query” caught my eye be­cause I’ve been liv­ing off stream and river wa­ter my­self for sev­eral years.

Like Bratj­man’s stream, our wa­ter is usu­ally clear which al­lows for a sim­ple, low-tech method of qual­ity as­sur­ance which I’ve de­vel­oped and am happy to share.

I pour about 500ml into a glass con­tainer with good op­ti­cal prop­er­ties, hold it up to a strong light and fo­cus closely on the wa­ter.

This nor­mally re­veals per­haps half a dozen tiny lit­tle gog­gas wrig­gling and thrash­ing around in a merry whirl like a bunch of New-agers at an all-night rave.

If the ac­tiv­ity is con­sis­tently en­er­getic then I reckon that the wa­ter must be good to drink or they wouldn’t be so happy in it. Tired, list­less, mori­bund spec­i­mens are an in­di­ca­tion of sub-stan­dard wa­ter which I store sep­a­rately for vis­i­tors I don’t like. Stephen Pain Rivers­dale
