Perchlorate in Water


Source of Perchlorate in Water: Perchlorate is a man-made compound of natural sources that is used in the production of rocket-fuel, fire-works, explosives, and some fertilizers. When it is found in groundwater and wells, it is often a sign of industrial pollution and improper chemical disposal. The EPA has only recently decided that this contaminant must be regulated by municipal water treatment plants because about 4% of public water systems across the United States have tested positive. The EPA has a regulated amount of only 1 ppb as a maximum level. Up to 17 million Americans may be exposed to contaminated drinking water containing perchlorate at greater than 4 parts per billion.  Perchlorate is a wide-spread problem in the United States with up to 35 states having it in their water supplies. 

Symptoms of Perchlorate: Perchlorate is a toxin and is considered an endocrine disrupter for humans. Exposure to perchlorate in drinking water is dangerous, especially for pregnant women, infants, and children because it can harm the body’s production of hormones necessary for mental and physical development. Additionally, it can affect the thyroid's function and production. 

Filtration Solutions for Perchlorate: Perchlorate as a fuel oxygenate is very hard to remove. Standard carbon absorption has not been shown effective, unless the carbon is specialized. However, Reverse osmosis water treatment systems that are NSF 58 certified can provide a 95% reduction rate of perchlorate.
