Common Contaminants Found In Drinking Water

According to USA Today, approximately 63 million Americans were exposed to unsafe drinking water at least one time in the 10 years following 2017. As a parent and homeowner, you want everyone who turns on the tap to take a drink of water or takes a shower in your bathroom to be safe. Unfortunately, you can't always assume that your drinking water is safe just because you live in the United States.

Here are a few of the most common contaminants found in drinking water and why you need to protect your family by purchasing a whole home water filtration system.


You've likely heard about the dangers of lead and the serious side effects lead contamination can cause, including:

  • Headache
  • Irritability
  • Severe stomach pains
  • Memory loss
  • Nausea

If an individual is exposed to larger concentrations of lead over an extended period of time, it can lead to more devastating symptoms, such as fertility issues, heart disease, high blood pressure, and kidney damage. Lead gets into your drinking water from plumbing corrosion or runoff from nearby industrial plants.

Even if your pipes are newer, there is still a small chance that there could still be trace amounts of lead if you have metal pipes. The cost of completely replumbing your home is exorbitant, so the best option to protect your family is to install a quality whole home filtration system.

Talk to an expert about the right filtration system if your water has tested positive for lead or even if you are concerned about lead contamination in an older home.

Viruses and Bacteria

There are several types of viruses and bacteria found in drinking water. Some of the bacteria found in drinking water are also beneficial. However, despite municipal treatment plants using powerful technology to eliminate dangerous bacteria and viruses, there is still a chance you and your family could become sick.

Here are a few common types of bacteria and viruses they are found in drinking water:

  • E. coli. Otherwise known as Escherichia coli, E. coli is a serious bacteria that causes nausea, stomach pain, and vomiting.
  • Salmonella. Another dangerous bacteria, Salmonella has many of the same symptoms of E. coli, plus fever, chills, and headache.
  • Giardia lamblia. The microscopic Giardia lamblia parasite causes giardiasis, which has symptoms that include headaches, nausea, vomiting, diarrhea, bloating, and exhaustion.

Norovirus is another potential virus that is found in drinking water. This dangerous virus spreads quickly and can cause severe nausea, vomiting, and diarrhea. Talk to a professional about a water filtration system that will protect your family against dangerous water-borne viruses and bacteria.


Finally, one of the most common types of contaminants found in drinking water is nitrates. Nitrates are both found naturally in rainwater and ground water, and they are also introduced into drinking water through fertilizer runoff. The presence of large amounts of nitrates in drinking water can be dangerous to young children, adults, and pregnant women.

However, one of the most dangerous conditions linked with exposure to large amounts of nitrates is methemoglobinemia, or blue baby syndrome. According to Healthline, blue baby syndrome occurs when an infant cannot sufficiently oxygenate their blood. The name "blue baby syndrome" comes from the bluish tint a baby's skin gets when there is a lack of oxygen-rich blood.

Whether you have an infant in your home or not, a home water filtration system can help protect your family against nitrates. It is especially important to protect against nitrates if your home has well water.

From harmful bacteria and viruses to nitrates and lead, there are several potentially dangerous contaminants found in drinking water. Luckily, you can protect your family from contaminants while enjoying amazing-tasting water by installing a whole home filtration system.
