Evaluation of Point-of-Use Filters and the Impact on Fluoride Concentration
Abstract
According to the Center for Disease Control and Prevention (CDC) the United States has one of the safest water supplies in the world with 90% of Americans getting their water from community water systems (5). Community water systems are subject to regulations set forth by the Safe Drinking Water Act (5). The Environmental Protection Agency (EPA) requires a consumer confidence report (CCR) be delivered to the consumer no later than July 1 of each calendar year. This CCR has the most recent water source assessment information and a brief summary of the systems susceptibility to potential sources of contamination. The EPA sets legal limits on over 90 contaminants in drinking water (10). Despite guidelines, regulations, and frequent testing, contamination can still occur (10). Possible sources of contamination include the following: sewage release, naturally occurring chemicals and minerals, local land use practices (fertilizers/pesticides), manufacturing processes, manufacturing on-site waste water treatment systems, improperly treated water, and improperly maintained water distribution systems. Widespread water filtration started in the 1890s and has contributed to the drastic decrease in mortality due to waterborne disease (10). Roughly 100,000 people in the US get sick from foodborne, waterborne, and enteric illness combined each year, according to National Outbreak Reporting System (NORS) (10).
