Individual Drinking Water Supply
Small communities and rural areas not served by central sewer and water supply systems have reason to be concerned about their home water quality.
In the Rocky Mountain region, where the bedrock is formed of granite, there is often not enough soil for proper percolation of waste water through leach fields. Leach fields usually need about eight feet of soil through which wastewater travels on its way to the water table. Where there is not enough soil, unclean waste water can reach the water table. Faulty waste water disposal systems are responsible for contamination of the groundwater in many areas of the Rockies. For those using wells as their water supply, this is a serious concern.
The most common and serious contaminates from human sewage in drinking water are nitrates and microorganisms. Infants and pregnant women are at special risk, but all individuals who are exposed are in danger from bacteria, viruses and other microbes entering the drinking water from contaminated ground water.
