Most of us assume that the quality of the drinking water coming out of our taps must be fine. It's always available and seemingly protected, apparently clean and generally recognized as safe. In reality however, the state of our drinking water is overall quite poor and on the decline. Much of our drinking water is recycled waste water... yes, it is often water that travels through our bodies and out to sewage lines, eventually finding its way through our municipal water treatment system and then back to our homes as drinking water. In other cases, the water comes to us from reservoirs, often completely unfiltered, through 100 year old pipes while being treated with harsh chemicals that remain in the water we drink. Or, in the case of people relying on well water, we have concerns about agricultural and industrial toxic runoff leaching into the water supply as well as high levels of bacteria. These often go undetected until it's too late.
