It was only in the early 1900’s that chlorination was introduced to
prevent influx of waterborne diseases like typhoid fever and cholera. However this solution exchanged one
problem for another. The chemical reaction of the disinfectant with organisms in the water created a
cancer-causing compound Trihalomethanes (THMs). The EPA has identified over 600 disinfection by-products but
only 11 are regulated.
Chlorine can control most biological contaminants but not all of them like giardia or
cryptosporidia. These chlorine resistant cysts are fatal to people with weak/suppressed immune systems (ie:
surgical patients, elderly, HIV/AIDS patients).
USA has been using fluoride for tooth decay control and water
disinfectant. In contrast, it has been banned in 27 countries of
European Union and China. US Congress is only now scrutinizing its effectiveness and health impact.
Minimum “safe levels” of drinking water are established as “safe”. But what if those
contaminants are exceeded and the safe standard is very marginal? The impact may not be great when exposed for
short duration but if accumulated thru time it can cause liver disease, cancer or cardiovascular disease. Today’s
safe may be considered tomorrow’s toxic level.
Well water is not much better off than utility water because of the farming with
chemicals, pesticides, herbicides. All these chemicals make their way into the groundwater.
Bottled water has its set of woes. Deceptive practice as to source of water (ie
calling well water as spring fed water). Contaminants found in bottling such as bacteria, chemicals, dissolved
solids, heavy metals etc… Certain grades of plastic bottles used for water distribution leech out
