What makes tap water unsafe for drinking?

The Hidden Dangers of Tap Water

1. Arsenic

Arsenic is a natural metalloid chemical usually present in groundwater. It poses health problems when taken at some dangerous amounts.

This chemical is present in residential tap water through agricultural or industrial pollution or a private well.

Arsenic poisoning may lead to the following health issues:

  • partial paralysis
  • numbness in hands and feet
  • vomiting, nausea, stomach pain, and diarrhea
  • discoloration of the skin
  • blindness

Arsenic Poisoning Definition: also known as arsenicosis; a condition where an individual consumes a dangerous level of arsenic from drinking groundwater or tap water.

2. Chlorine

This is also another naturally-occurring chemical element that does not only kill bacteria and germs but also causes damage to the human body when taken in dangerous amounts orally and through inhalation.

When chlorine enters the body, it reacts with water and produces corrosive acids. People exposed to excessive chlorine may experience the following health issues:

  • chronic cough
  • breathing difficulty
  • chronic sore throat
  • chest tightness
  • airway irritation

3. Fluoride

Fluoride is a mineral present in the teeth and bones and in the air, rocks, plants, soil, and water.

Although naturally-occurring in the human body, excess amounts of fluoride from tap water pose some health issues, such as fluorosis and severe skeletal problems.

Fluorosis Definition: mild discoloration of the teeth due to excessive amounts of fluoride.

4. Heavy Metals

Heavy metals are known for their potential toxicity especially in environmental contexts. Mercury, lead, copper, chromium, cadmium, and aluminum all pollute tap water.

If taken excessively for a long time, these heavy metals found in tap water can harm your health. Aluminum, for example, can increase risks of the following health conditions:

  • brain deformities
  • Parkinson’s disease
  • dementia
  • Alzheimer’s disease

Lead can damage the kidneys and increase the risk of having high blood pressure.

5. Herbicides and Pesticides

These chemicals used to get rid of insects and control unwanted plants are toxic in nature. They can sometimes sneak into water supplies, especially in groundwater of agricultural areas.

When taken into the human body through tap water, these chemicals can cause the following:

  • eye and skin irritation
  • headache
  • allergic sensitization
  • extreme weakness

6. Water Softening

Water softening is the process of removing heavy ions that clog up plumbing, such as calcium and magnesium, from water.

But, there is a downside to this process – it takes away natural minerals essential for the body. Aside from this, water softening replaces the ions removed with sodium chloride, which, when ingested in large amounts, can cause:

  • respiratory distress
  • convulsions
  • hypernatremia (a condition where there is too much sodium in the body that can lead to excessive thirst)
  • vomiting
  • gastrointestinal tract irritation

7. Nitrates

These inorganic compounds are commonly present in processed meats, such as hot dogs, bacon, and ham, functioning as preservatives. They are also present in tap water because they naturally occur in the air, soil, and water.

The most controversial health effect of excess nitrates is methemoglobinemia, a blood disorder that involves an abnormal amount of methemoglobin. When the body produces too much methemoglobin, it begins to replace the normal hemoglobin count, which can lead to a lack of oxygen supply in the cells.

Methemoglobin Definition: A type of hemoglobin that is unable to carry oxygen in the blood; results in slate-gray, cyanotic skin color.

8. Radon

Radon is a natural gas present in the air and occurs in water tapped by wells. When groundwater passes through rocks with uranium, it releases radon into the water.

If your tap water has radon, you may be at risk of stomach cancer or internal organ cancers.

Uranium Definition: It is a kind of heavy metal that is an abundant source of concentrated energy.

9. Diethyl Phthalate

Diethyl phthalate is a colorless liquid typically used to make flexible plastics. This compound can sneak into groundwater from landfill leaks.

Drinking tap water contaminated with diethyl phthalate can lower sperm quality and count, disrupt sex hormone levels, and alter genital developments.

10. Bacteria

Escherichia coli, for example, has been an issue in dirty water. It is an indicator that water has animal waste or sewage contamination.

E. coli can cause health concerns like:

  • nausea and vomiting
  • abdominal tenderness, pain, and cramping
  • diarrhea

Legionella is a type of bacteria that can affect the lungs and cause localized infections.

Salmonella can cause the following health issues:

  • food poisoning
  • typhoid fever
  • gastroenteritis (the inflammation of the intestines and stomach as a result of viral infections or bacterial toxins)

11. Phosphates

These are compounds of phosphate ions commonly present in fertilizers as plant nutrients and in detergents as a water softener. The presence of phosphates in water promotes excessive algae growth that makes the water dirty when algae die.

Phosphates enter water systems when dissolved rocks mix into groundwater. High levels of phosphates in the body can put people at high risk of hardened arterial walls.

12. Pharmaceutical Drugs

Small amounts of pharmaceutical drugs, such as antibiotics, mood stabilizers, and birth control pills, are also present in some tap water systems. These drugs get into the water when some people flush them down their toilets when not needed anymore or pass some amounts of drugs through urine and feces.

The levels of drugs present in the water might be low, but it is still unsure whether the levels are low enough to discount harmful health effects.

13. Dioxins

Dioxins are toxic chemicals not produced or commercially used in the country. They are contaminants produced in combustion processes, like cigarette smoking and forest fire, and discharges from chemical factories.

When released in the environment, these chemicals linger around that we can breathe them in the air or drink them from tap water. Excess amounts of dioxins can cause reproductive difficulties and increase the risk of developing cancer when consumed in tap water for a long period.


The hidden dangers of drinking tap water have been exposed. You now have a better understanding of how the water poses mild-to-severe health problems.

Opt to have a water ionizer instead. Tyent water ionizers produce hydrogen molecule-rich drinking water that can help balance out irregularities in your system.

    1. Hi, Norah. Thanks for your wonderful questions! Yes, it is definitely possible, and we have the perfect solution for you and your family. Let me explain. First, it’s important to understand that there is no water ionizer on the market that will remove 100% of fluoride by using ONLY the regular ionizer filters by themselves. The good news is that Tyent offers an amazing pre-filter that removes fluoride as well as chromium-6 (the dangerous cancer-causing chemical that was exposed in the movie Erin Brockovich). No other water ionizer company has this type of filter – it’s exclusive to Tyent.

      You’ll also be happy to know that all Tyent Water Ionizers have a dual filtration system. The primary filter contains ACF active carbon that removes large contaminants like organic compounds, chlorine, rust, and sediment, while the secondary filter contains ceramic material that balances the ions and minerals in the water. These filters have the same micron level and filtration capabilities as a kidney dialysis machine, which is .01 micron. Tyent’s Ultra Filters come standard with each of our ionizers, and they remove over 200 contaminants including 99% of lead, and up to 99% of mercury, beryllium and uranium.

      You can see our third-party lab report about those here. When you combine our water ionizer’s Ultra Filters with the fluoride/chromium-6 filter, you’ll have the cleanest and healthiest water available. We take great pride in ensuring that our customers have the safest and freshest water.
