It’s an unfortunate fact that most tap and well water contains moderate to high levels of contamination from industrial and environmental pollution.
Whether it be a lake, river, glacier or well, all sources of water contain some level of contamination.
Some contaminants occur naturally (minerals) while others are man-made (chemicals and byproducts). Water from surface water (river or lake) is often exposed to acid rain, storm water runoff, farm pesticide runoff and animal and industrial waste. Water from groundwater (private wells or public water supplies), is often contaminated by disease-producing pathogens, seepage from landfills and septic systems, disposed hazardous household products and agricultural chemicals.
Most contaminant levels are not high enough to cause immediate sickness but are more likely to cause chronic health effects. With symptoms occurring long after repeated exposure to small amounts of the contaminants.
