Water Quality

Is Your Tap Water Safe to Drink?

7 min read

Legal water isn’t necessarily safe water.

The legal limits for most contaminants in your tap water hasn’t been updated for over 20 years, and getting a passing score from the government doesn’t mean that your family should be drinking it.

Luckily, there’s a simple solution to purify even the most polluted tap water, but more on that later...

For now, let’s take a closer look at what might be lurking in your tap.

ESSENTIAL TAKEAWAYS

Although tap water is monitored by the EPA, it often does not pass safe water testing standards.


Harmful contaminants such as chlorine, arsenic, lead and even nuclear waste are often found in drinking water across the country.


These harmful contaminants have been linked to multiple health issues including, neurological disorders, birth defects and cancer.


The best way to ensure your family is drinking clean healthy water is to use a water filtration device in your home.

The Environmental Protection Association (EPA) enforces federal tap water laws according to the Safe Drinking Water Act, which sets minimum safety standards for the state and local governments. They’re responsible for monitoring more than 90 different contaminants and work closely with local wastewater treatment plants to purify water for human consumption, and ensure your tap water is safe. 

Every year, local water suppliers conduct safe water testing and publish a public report for residents.

Unfortunately, not all of the tests pass with flying colors…

Some of the Scariest Contaminants Still Slip Through the Cracks

Many of the most harmful contaminants are difficult to treat and inaccurate to test for, and it isn’t uncommon for pollutants to slip through the cracks. 

Some of the most common contaminants in tap water are:

  • Arsenic
  • Copper
  • Fluoride
  • Chlorine
  • Radon
  • Uranium
  • Pesticides
  • Bisphenol-a (BPAs)
  • Manufacturing operation byproducts
  • Sewer overflows and wastewater releases
  • Runoff from concentrated animal farming operations

But what does this mean? Is tap water safe for your family’s health?

The Long-term Health Effects of Contaminated Tap Water

In most cases, trace amounts of contaminants won’t make you sick that day, that week, or even that year, but dangerous side effects can accumulate over time. 

Depending on the type of contaminants, side effects can include:

  • Damage to the bone marrow and red blood cells
  • Learning difficulties in children
  • Weakened immunity
  • Cardiovascular risks
  • Kidney damage
  • Birth defects
  • Anemia
  • Cancer

Even tap water that meets the EPA’s safety guidelines can ultimately harm your health. 

A 2019 study from the Environmental Working Group linked over 100,000 cases of cancer to contaminated tap water. 

Two of the biggest culprits were the heavy metal arsenic and (drum roll please) chlorine! The very tap water disinfectant that’s supposed to be keeping your family safe.

Let’s take a closer look at what might be lurking in your water…

Is Arsenic Lurking In Your Tap Water?

Arsenic makes its way into the water supply through industrial activities like coal plants, petroleum refinement, and runoff from animal feed and pesticides. 

The gut easily absorbs arsenic and spreads it throughout the body quickly. In the long run, this can lead to hormone imbalances, severe skin problems, and cardiovascular and nervous system disorders. 

Worst of all, arsenic exposure increases the risk of several types of cancer, including:

  • Skin cancer
  • Lung cancer
  • Liver cancer
  • Kidney cancer 
  • Bladder cancer
  • Prostate cancer

Symptoms can take years to develop, so you probably won’t know that something's wrong until it’s too late. 

DID YOU KNOW?

The EPA guidelines allow for trace amounts of arsenic in your tap water. A contaminant linked to multiple types of cancer, as well as brain damage.

With a contaminant this toxic, you’d think that the EPA would have a zero tolerance policy, but they actually allow up to 10 ug/L! 

So if you want safe tap water with zero arsenic, you’ll have to install an in-home treatment system that can handle hard-to-remove toxins.

Health Effects of Chlorine, Chloramine and Fluoride

Municipal water suppliers add chlorine to kill germs and fluoride to prevent cavities.

Chlorine not only makes your tap water smell and taste bad, but it also produces compounds called disinfection byproducts (DBPs), which promote inflammation and destroy vitamin E---one of the body’s most important antioxidants. 

Studies have also linked DBPs to heart disease, cancer and liver failure.

One of the most shocking studies found that people who drank chlorinated tap water were up to 53 percent more likely to develop bladder cancer and up to 93 percent more likely to develop colon cancer.

Due to the harsh effects of chlorine byproducts, many municipalities have switched to chloramine, a similar disinfectant with potentially fewer side effects, but the long-term effects are still unknown. Roughly 1 in 5 Americans drink water that contains chloramines.

Tap Water Fluoride

The government has been adding Fluoride to your tap water in an attempt to strengthen teeth and gums, even though almost all over the counter toothpastes now include adequate amounts of fluoride.

For over 40 years, the government has been adding fluoride to tap water to help prevent cavities, but moderate-to-high levels have been shown to cause serious health problems, like:

Fortunately, 99.9% of fluoride can be removed with a combination of reverse osmosis, charcoal filtration and ion exchange. All of which are used in Cloud Water Filters. 

What Happens When Lead Leaches Into Your Water?

Did you know that pipes installed before 1986 may contain lead?

As pipes age, lead fittings can corrode and leach lead into your drinking water, killing brain cells and promoting disease. 

This is exactly what happened in the Flint Water Crisis, where over 9,00 children were exposed to lead.

Lead has especially devastating effects on young children. As it accumulates in the body, it can stunt brain development and cause behavioral changes, hearing loss and slowed bone growth. 

It also weakens immunity, increases the risk of cancer, and damages the heart, kidneys and nervous system. 

Nuclear Waste Is More Common Than You Think

If you thought there’s no way that the U.S. had nuclear waste in their tap water, think again…

Uranium and radium are found in the water supplies of over 170 million Americans. Texas and California are especially bad. 

Radium is a byproduct of the radioactive decay of uranium, and both are linked to kidney toxicity, birth defects and cancer. 

Luckily, a high-end reverse osmosis system can remove nuclear waste lickity-split. 

10 Worst U.S. Cities for Water Contamination

Texas and California aren’t the only U.S. states with serious tap water quality issues---locations across the country struggle to provide safe drinking water to their residents. 

While rural areas have some of the worst contamination, several major cities also suffer from aging lead pipes and poor enforcement standards. 

Some of the worst places for water quality are:

  1. Detroit, MI: Flint’s water contamination has spread to nearby Detroit. Michigan’s aging pipes have been a serious problem, and in September 2018, 57 out of 86 Detroit public schools tested positive for elevated levels of lead and copper. 
  2. Milwaukee, WI: Milwaukee made the news in 2018 when health officials failed to warn families about contamination issues after their children tested positive for lead poisoning from 2015 to 2017. 
  3. Baltimore, MD: Baltimore has elevated levels of lead in roughly a dozen of its public schools. The city’s Druid Lake reservoir is clouded with disease-carrying particles. 
  4. Newark, NJ: From 2017 to 2019, Newark’s drinking water registered high levels of lead and haloacetic acids (HAAs), a type of disinfection byproduct that can form when chlorine mixes with organic matter in water. 
  5. Newburgh, NY: The small city of Newburgh in upstate New York declared a state of emergency in 2016 when a massive 1.3 billion-gallon reservoir tested positive for perfluorooctane sulfonate (PFOs), a dangerous pollutant linked to kidney disease and cancer. 
  6. Washington, DC: The country’s capital is notorious for having issues with lead-contaminated water since the early 2000s. By 2016, over 12,000 buildings still got their water from lead-tainted pipes.
  7. Charleston, WV: In 2014, a massive industrial spill released a trail of chemicals used to wash coal. As of 2017, they still tested positive for multiple contaminants.
  8. Miami, FL: Miami is contaminated with toxic chemicals called polyfluoroalkyl substances (PFAS). They are called “forever chemicals” because they linger for thousands of years and remain in the body for life. 
  9. Brady, TX: Texas is one of the most contaminated states in the country thanks to widespread nuclear waste, and the small city of Brady is one of the worst off. Radium levels registered at nine times above the EPA’s limit. 
  10. Dos Palos, CA: California is right up there with Texas for some of the worst water contamination in the country. In Dos Palos, residents have switched to bottled water after discovering that their water contained trihalomethanes, a group of chemicals linked to kidney problems and cancer. 

Tap Water Doesn’t Have to Be Dangerous

As scary and widespread as water contamination is in the United States, there’s no need to be afraid.
