According to the U.S. Environmental Protection Agency (EPA), chlorine levels of four parts per million or below in drinking water—whether from a private well or municipal reservoir—are acceptable from a human health standpoint. But you also need use some filtration stuff for reducing any chlorine. It does water more clear and tastier without smellihg any chemicals.
first of all chlorine was used in drinking water to reduce waterborne infectious diseases in Jersey City, New Jersey more than a century ago. It was such effective metod for destroying potentially harmful bacteria and any viruses that it spreaded far and wide. Today some 98 % of water treatment facilities in the U.S. use some form of chlorine to clean drinking water supplies. Indeed, some consider the chlorination of drinking water to be one of history’s greatest public health achievements.
But there is an another side of mix water and chlorine. The problem is situated in chlorine’s ability to interact with organic compounds in fresh water to create chemical reaction, which when ingested can encourage the growth of free radicals that can destroy or damage vital cells in the body. Besides cancer, there will be other health issues including asthma, eczema, heart disease and higher miscarriage and birth defect rates.
Those with their own private wells who are skittish about chlorine have other options for disinfecting their water. One baby step would be to replace chlorine with chloramine, an ammonia derivative that doesn’t dissipate into the environment as rapidly as chlorine and has a much lower tendency to interact in bad ways with organic compounds in the water. However, traces of chloramine in the water may not be to everyone’s liking either, because it causes rashes after showering in a small percentage of people and can apparently increase lead exposure in older homes as it leaches the heavy metal off old pipes.
