Fluoride has been added to America’s drinking water for nearly 80 years in an effort to reduce dental cavities. East of the Mississippi, fluoridation is widespread. West of the Mississippi, it is more limited. In Minnesota, Illinois and Kentucky, nearly everyone who receives water from a municipal source gets fluoridated water. Close behind are North and South Dakota, Ohio, Virginia, Georgia, Iowa, Michigan, West Virginia, Connecticut and Indiana where fluoridation is in about 90% of governmental water sources. However, in recent years, the addition of fluoride has become controversial.
The answer to “How much is too much?” has different answers depending on who is asked.
Lower levels protect against the skeletal fluorosis that can occur when too much fluoride is ingested. Fluorosis causes deformities of bones. Dental fluorosis or mottling and pitting of the teeth can also occur. However, these are not the only concerns about the practice of adding fluoride to water.
In recent years, groups like Food & Water Watch, Fluoride Action Network and American Academy of Environmental Medicine have asked the EPA to reduce or completely eliminate fluoridation of drinking water. These groups cited studies that found that fluoride causes neurotoxicity in humans.
Fluoride neurotoxicity can affect adults and infants, and fetuses through the mother’s exposure to fluoride. Children are especially sensitive to this mineral. Many studies have shown that children in areas with high levels of fluoride in water had significantly lower IQ scores than those in low-fluoride areas.
One researcher even stated that “Fluoride seems to fit in with lead, mercury, and other poisons that cause chemical brain drain. The effect of each toxicant may seem small, but the combined damage on a population scale can be serious, especially because the brain power of the next generation is crucial to all of us.”
Limited research has noted a connection between fluoride and bone cancer in young males. More research is needed to confirm any adverse effects of fluoride in drinking water.
To determine your local level of fluoride, the Basic Water Test from ETR Laboratories will analyze your water and measure the fluoride along with 52 other substances or water attributes. You can then determine if you need to filter your drinking water to reduce any health risk. To remove fluoride from your water, you will need to add one of these water treatment systems to your home:
The decision about fluoride is yours. A fast and accurate test from ETR Laboratories will help you make your choices and supply your family with the best water possible. Get the Basic Water Test today so you can make a fully educated decision.
Last Friday night, during a torrential rainstorm, a 42-inch sewer force main near Haverhill’s main pumping station failed. The pipe, which carries wastewater from the city’s main pump station to its treatment plant, dates back to the 1970s.
On June 5, 2026, residents in nearly a dozen neighborhoods in Northwest Washington DC started noticing something wrong with their water pressure. DC Water received calls from customers experiencing low to no pressure at multiple locations at the same time the Fort Reno Pumping Station was experiencing fluctuating power issues, with a full loss of power hitting at around 12:30 p.m.
No state in America has perfectly clean tap water. That is not a dramatic claim. It is simply what the data shows. Based on EPA violation data, contaminant testing, and infrastructure assessments, the states with the most documented tap water problems in 2026 are Texas, California, New York, New Jersey, Florida, Pennsylvania, Louisiana, Arizona, Wisconsin, and Massachusetts. The most common problems across these states are PFAS, lead service lines, disinfection byproducts, arsenic, and nitrates.

The Real Cost of Not Trusting Your Water (And What You Could Do Instead)
About 59 million Americans have access to tap water or a private well and choose not to drink it. Since just before the Flint water crisis began in 2014, the number of adults who avoid their tap water has increased by 40 percent, and among children it’s risen by 63 percent.
This past week, just ahead of Memorial Day, the Surfrider Foundation released its annual Clean Water Report. The headline number was hard to ignore. Years of neglect and underfunding have left the country with an estimated $630 billion backlog in needed wastewater infrastructure repairs and upgrades.
