- More than half of the chemicals found in U.S. drinking water are unregulated, and many of the legal limits may be too lenient for safety
- Firefighting foam used on military bases and other fire testing sites have contaminated many water tables across the U.S. with PFCs — chemicals linked to thyroid disease and cancer
- Agricultural runoff, prescription drugs flushed down the sewer, and aging water pipes are other significant sources of water pollution

"Radon, arsenic and nitrates are common pollutants in drinking water, and trace amounts of drugs including antibiotics and hormones have also been found ...
But water contaminants and water quality vary from one local water utility to another, so you want to purchase a filter that is effective at capturing the right contaminants.
You can request a copy of your water utility's annual water quality report3 — called a right-to-know or consumer confidence report — to find out which contaminants in your local water are of concern ..."
Many Chemicals Found in Municipal Water Are Unregulated
Firefighting Foam Has Contaminated U.S. Drinking Water
"Research on people in West Virginia and Ohio who had consumed water contaminated by leaks from a nearby DuPont factory showed probable links between the chemical and six diseases, including kidney cancer.
Cervera soon discovered that the very same chemical, as well as a related one, PFOS, had been found in drinking water in her area. Both were part of a larger class known as perfluorinated chemicals, or PFCs, 'emerging contaminants' that were still being studied — and had yet to be regulated.
And, according to public notices from the local water and sewer authorities, both had come from foam that was used to put out airplane fires and train soldiers at two nearby military bases ..."
Many Areas Around Military Bases Are Affected by PFC Contamination
"Indeed, according to a 2013 presentation by the Air Force, PFCs were found at every Air Force base that had been tested, which so far includes Randolph in Texas; Robins in Georgia; Beale and McClellan in California; Eglin in Florida; Ellsworth in South Dakota; and F.E. Warren in Wyoming."
PFC Contamination Likely a Greater Problem Than Anyone Can Fathom
"There's little doubt that, together, widespread use of firefighting foam has contributed to the exposure of huge numbers of people to PFCs. EPA monitoring begun recently found PFOS in water systems serving almost 10 million Americans, most of whom have no idea they're drinking it.
The number of potentially exposed people climbs to more than 14 million when the other five PFCs now being monitored by the EPA are included. And those six chemicals are only the tip of the iceberg; more than 2,000 PFCs have already been identified on the global market, and scientists expect that number to climb to 4,000."
Toxic Drinking Water Becoming More Common Around the U.S.
"... [A]bnormally high levels of e. coli, trihalomethanes, lead, and copper have been found in the city's water, which comes from the local river (a dead body and an abandoned car were also found in the same river) ... [R]esidents say that the city government endangered their health when it stopped buying water from Detroit last year and instead started selling residents treated water from the Flint River ..."
