In the past, we've mentioned Legionnaires' disease, which is a disease caused by a waterborne bacterium. Here we'll discuss three other types of waterborne organisms: coliforms, which, although not usually harmful, can be a sign of other bacteria that are harmful; and iron and sulfur bacteria, which are seen as annoyances rather than a health … [Read more...]
