Water Contaminants
CHLORINE
Chlorine is added as a sanitizer. It removes the nasty bacteria such as E-coli, MRSA (golden staph) etc. While it eats up all the nasty bacteria, it also eats up all the good bacteria (a bit like antibiotics) and nutrients in your system. Chlorine is linked to asthma, eczema, psoriasis, bladder cancer, heart disease, miscarriage, and birth defects. The best way to remove it is filtering it through a carbon block filter. A quick fix is at least refrigerating your water, or at least running it through an average filter (such as a brit filter) and refrigerating it. The chill will get rid of some of the chlorine at least. The carbon block filter will remove 99.9% of chlorine, if it has small pores and is of good quality.
FLOURIDE
Fluoride is added to water to prevent cavities. It is a pretty controversial topic at the moment. It is definitely worth investigating and making up your own mind. I grew up on fluoridates water (Tasmania was, proudly, the first place in the world to get fluoridated water) and still go cavities, and we were not even allowed to eat sugar, sweets (lollies) or carbonated drinks. Basically Fluoride is toxic, it is fatal in large doses and is actually the by product of uranium environment. It is linked to osteoporosis, bone cancer, and Down syndrome. It can also be filtered out with a good carbon block filter, or reverse osmosis treatment.
LEAD
Lead leeches into municipal water from distribution pipes, especially in older cities whose pluming was done before laws were passed to restrict lead in pluming. Lead poisoning causes brain damage and lesser intelligence, high blood pressure and kidney problems.
ARSENIC
Organic arsenic occurs naturally in rocks, soil and water and plants and animals. High inorganic arsenic levels can also come from certain fertilizers and animal feeding operations. Inorganic arsenic can cause stomach lining irritation, intestinal irritation, decreased production of red and white blood cells, skin changes and lung irritation. Organic arsenic cannot cause cancer or DNA mutation, but can cause nerve injury and stomachaches.
Exposure to inorganic arsenic can cause various health effects, such as irritation of the stomach and intestines, decreased production of red and white blood cells, skin changes and lung irritation. Organic arsenic can cause neither cancer, nor DNA damage. But exposure to high doses may cause certain effects to human health, such as nerve injury and stomachaches.
CYANIDE
Cyanide is a byproduct of treating waste with chlorine. Cyanide can cause cell death, fatigue, shortness of breath, seizures and heart disease.
NITRATE
Nitrate is a byproduct of animal waste and fertilizer. It can cause anencephaly in fetus or blue baby syndrome if ingested in 10ppm (the EPA states 10ppm is a safe level though). Atrazine is a pesticide which seeps into ground water. It can cause heart, lung and kidney congestion, weight loss, and adrenal damage, muscle spasm, blood pressure issues and prostate cancer. Halcacetic acids come from waste treatment process. They cause brain cancer, lukaemia, and miscarriage.
