Chlorine is added to the water by many municipal water systems as a disinfectant and to control Microbial contaminants. In addition to making tap water taste and smell bad Chlorine can be absorbed through physical consumption, through skin while bathing and inhaled through evaporative process while taking a hot shower. Chlorine is known to dry skin and hair and cause irritating effects to your eyes and nose and may be linked to other health risks.
Lead is toxic to health even at low doses. Leaching from household plumbing systems and deposits of lead byproducts into drinking water sources are increasing. The amount of lead found in tap water varies greatly and depends on factors such as the amount of time the water is exposed to the plumbing infrastructure the waters PH and temperature. Lead in drinking water can cause a variety of adverse health effects.
Microbial Cyst contain parasites that can be found in lakes and rivers and can enter the water through sewage, leaking septic tanks and runoff from farm operations. Many cysts are resistant to the water disinfection process making cysts a health risk in tap water.
Mercury enters drinking water systems through erosion of natural deposits, contaminated liquid and gas discharge from refineries, factories, agricultural and manufacturing runoff.
Exposure to mercury over time is toxic and can cause kidney damage and other health related issues.
Volatile Organic Compounds include a variety of chemicals emitted as gases. Thousands of products contain VOC’s so it’s no surprise some of these elements end up in our drinking water. When water is heated and vaporized, your body can absorb these contaminants.
Pesticides have the potential to contaminate drinking water supplies. They are applied to farmlands, gardens and lawns and can make their way into ground water or surface water systems that feed drinking water supplies.
Herbicides can enter the drinking water system through runoff from rainfall and irrigation and are deposited into oceans rivers and lakes. Atrazine is known to interfere with the bodies hormonal activity and reproductive organs.
Methyl Tertiary Butyl Ether is added to gasoline for the reduction of carbon monoxide emissions.
Seepage from decaying and unmonitored underground storage tanks, spills and discharge from refining and petroleum processing pipelines and operations and discharge commercial and private boat engines into lakes and rivers can produce increased levels of MTBE in municipal water systems.
