There is a lot of misinformation available about water quality. If taken as true in the wrong situation they could be very costly, they might even cost you your life.
The first myth I want to mention is the belief that ground water is pure. See my article on why I dislike the term “purify” when it concerns water. I have heard this over and over again, “if we were all drinking ground water we wouldn’t need all these chemicals and we would all be healthier”. This simply isn’t true. Ground water does contain bacteria, it is usually free from pathogenic organisms, but that is not guaranteed, and if your system isn’t used to the specific bacteria in the ground water they may still make you a little sick.
The second myth I want to squash is the idea that sunlight, specifically the ultraviolet radiation will kill bacteria. Let’s think about this for a second. Using a lack of common sense, sunlight disinfection appears to be true. UV kills bacteria and the sun emits UV radiation sounds like a win-win scenario. However with a lot more common sense and some education behind it, it becomes apparent that all the lakes and rivers on the surface of the earth are exposed to sunlight. If UV from the sun disinfected water, there would be no microscopic life in our water and because this is the bottom of the ecosystem, there would be no ecosystem at all. Continue reading
