How often do you use water from a faucet?
Every day, Americans use tap water in many different ways. Such as for bathing, cooking, washing clothes and drinking. We rely on clean water so much that we tend to take it for granted.
The US has some of the safest drinking water in the world, but it’s not perfect. And it’s certainly not always safe. Treating water to reduce contaminants like harmful germs or chemicals is still critical to making sure that water is safe to drink.
That’s why it’s important to be proactive about learning where your water comes from, who regulates it and what you can do to ensure it’s up to par.
So let’s dive in.
Keeping Tap Water Safe and Healthy

How is water regulated?
The 1974 Safe Drinking Water Act put the Environmental Protection Agency (EPA) in charge of regulating America’s drinking water quality.
By EPA-ordinance, all US public water suppliers are required to uphold certain levels of water quality. Suppliers must also provide annual consumer confidence reports detailing the levels of certain contaminants.
Still, violations remain widespread. And some water systems have contaminants that the EPA does not look out for. Private water systems (residential wells) are not federally regulated at all. So it’s up to consumers to test their supply regularly.
Factors contributing to contamination include minerals found naturally in the ground, chemicals from factories and nitrates or fecal matter from farming. Additionally, outdated pipes leave millions of people vulnerable to lead contamination and bacterial growth.
Here are some fast facts from the National Resources Defense Council:
- Within the last five years, nearly 77 million Americans got drinking water from systems that violated federal protections.
- Millions of other water suppliers fail to test water properly or don’t report test results to health authorities or consumers — potentially sweeping additional issues under the rug.
- About 10% of Americans rely on water from private wells, most of which are under-tested.
All Americans should test their water at least once per year to be certain their water does not contain harmful contaminants.
Which water contaminants are harmful to your health?
Many water contaminants are not observable. Some, like arsenic, cause problems you can’t see, taste or smell, making regular testing incredibly important.
These are some of the more serious contaminants.
Lead: This heavy metal leaches from old pipes and plumbing fixtures. It can cause neurological and behavioral problems in children. Plus adverse health effects in adults.
Arsenic: Found naturally in rocks and soil, arsenic can dissolve into ground water and increase your risk of cancer.
Atrazine: This endocrine-disrupting chemical is one of the most commonly detected pesticides in US waters. Numerous studies link atrazine to increased risk of prostate cancer in men, increased risk of breast cancer in women and developmental defects in fetuses.
Chlorine treatment by-products: Chemicals used in drinking water’s disinfection process, such as trihalomethanes and haloacetic acids, may cause cancer and reproductive problems if present in high quantities.
Nitrates: Nitrates in high quantities can be harmful to pregnant women and infants. In rare cases, exposed infants can develop blue baby syndrome, a potentially fatal illness that prevents the blood from carrying oxygen.
Radioactive contaminants: Radioactive material can enter drinking supplies through leaks or improper waste storage. Exposure can cause cancer or kidney failure.
Pathogens: Bacteria, viruses and parasites that cause illness can find their way into water supplies. Symptoms include diarrhea, vomiting, cramps, nausea, headaches, fever, fatigue and even death.
Pharmaceuticals: Chemicals from pharmaceuticals and personal care products enter our water supply via human secretion or when they are flushed down the toilet. Whether they are present in sufficient levels to affect human health remains a topic of serious concern.
Perchlorate: This widespread toxic chemical, used in rocket fuel, explosives, and road flares, can interfere with thyroid hormone production. There is no federal standard for its presence in drinking water.
Vinyl chloride: Used to make PVC plastic products, this cancer-causing contaminant can leach from older piping.
Know that the presence of one or more of these contaminants in your water does not indicate an automatic health risk. But, they are not to be taken lightly.
