For over half a century now, community water systems have been adding fluoride to drinking water to help reduce the risk of tooth decay. Numerous long-term studies have demonstrated the soundness of this practice, prompting the U. Centers for Disease Control to call water fluoridation one of the ten most effective public health measures of the 20th Century. In the s, after years of study into the teeth-strengthening effects of fluoride, the U. Public Health Service recommended that drinking water utilities add fluoride at a rate of between 0. This recommendation held fast until when the service changed the recommendation to no more than 0. Why the change to guidelines that had been in place for over fifty years? The revision was in response to an increasing occurrence of dental fluorosis. Dental fluorosis is the only known health condition caused by fluoride.

Drinking water quality in the United States is generally safe. Inover 90 percent of the nation's community water systems were in compliance with all published U. Eight percent of the community water systems—large municipal water systems—provide water to 82 percent of the US population. Most of the public water systems that are out of compliance are small systems in rural areas and small towns. Drinking water quality in the U. There are many chemicals and substances for which there are no regulatory standards applicable to drinking water utilities. EPA operates an ongoing research program to analyze various substances and consider whether additional standards are needed.

In early US history, drinking water quality in the country was managed by individual drinking water utilities and at the state and local level. In the U. Public Health Service PHS published a set of drinking water standards, pursuant to existing federal authority to regulate interstate commerceand in response to the Interstate Quarantine Act.

For local drinking water utilities, these standards were basically recommendations and not enforceable requirements.

Hours of Operation

However, many municipal utilities began to voluntarily adopt the standards. State rules can be different from EPA's, but they must be at least as stringent. EPA defines a public water system PWS as an entity that provides water for human consumption to ogod least 25 people or at least 15 connections for at least 60 days a year.

There are three types godo public water system: community systems like click to see more or trailer parks ; non-transient, non-community systems like factories or schools with their own water source ; and transient non-community systems like rural restaurants or camps. Enforcement of drinking water standards in small water systems is less consistent than enforcement in large systems. Some violations included an overabundance of leadexceeding allowed rates for nitrate and fecal coliform. Around half of the most contaminated water systems were located in KansasTexas and Puerto Rico. Consumers can find out about these local reports on a map provided by Fluoride in Drinking Water Is it good. The regulation requires water suppliers to list the water sources, report detected contaminants and the system's compliance with National Primary Drinking Water Regulations in the annual reports.

Studies have shown that there can be more than 80 common contaminants in treated drinking water that may pose a risk to human health. These contaminants fall into two separate categories, acute and chronic effects. Though these chronic contaminants are rare in the US, [ citation needed ] there are many parts of the world that battle with these chronic contaminants and have to face the possible hazards on a daily basis.

A few common water-borne contaminants include aluminum, ammonia, arsenic, barium, cadmium, chloramine, chromium, copper, fluoride, bacteria and viruses, lead, nitrates and nitrites, mercury, perchlorate, radium, selenium, silver, and uranium. Some of these contaminants are easy to detect through human senses, such as smell and taste, and other contaminants are impossible to detect with the human eye. Some of the most dangerous contaminants are consumed without any notice. It is extremely important to know the difference between Wxter and biological contaminants. Chemical contaminants are elements or compounds that can either be naturally occurring or man-made.]
