Over a period of a few years I'd noticed that I became ill after our caravanning holidays, and this illness resulted in quite major symptoms, lots of time off work, and investigations including a brain and MRI scan. Nothing was ever found, but it happened several times. Whilst on holiday our pump stopped working and Mr Val A stripped it down to find what the problem was. The pump and pipes connecting the pump to the van were full of black slime and black filaments - even though we sterilised our water system regularly. At this point we immediately stopped drinking the water through the caravan taps, and I've not had any symptoms since.
On another forum there's been a discussion about water - and I wondered what, in the caravan water supply, could possibly have cause my problems. I did a bit of 'googling' because I know that algal growth in water exposed to sunlight is a problem, and that there are such things as toxic algal blooms, which produce neurotoxins (my symptoms were all neurological). I just wonder whether algae growing in our water supply (which was in the sunniest hottest part of France, usually) could have been to blame - the neurological symptoms described in some of these reports is exactly the sort of problems I had.
I keep harping on about the need to properly test the quality of the water that comes through aquarolls, in proper settings (ie not just a caravan set up in a test lab - but out in the field, with sunshine, showers, and possibly s..t!) but as far as I can see this has not been done.
We all connect our aquarolls, sterilise if that's part of our routine, and some of us drink the water - but perhaps there are other people being affected like I was without making the connection to the caravan water? I've suggested to Practical Caravan that the water quality be tested once before, and have raised it in the thread asking for suggestions about 'What to test' - but can I be the only one who thinks it is so important that I'm surprised it's apparently never been done?
