Unfortunately, the water we drink is often contaminated with some harmful and unpleasant water pollutants. While the water we are given is typically said to be safe, this is rarely the case. Here are some of the types of contaminants that you can often find in the water you drink.


These contaminants can be single elements or compounds. They can be either manmade or naturally occurring chemicals. Some examples of these water contaminants include chlorine, bleach, nitrogen, salts, pesticides, and drugs.


Biological contaminants are either living organisms or they come from living organisms. They refer to microbes or microbiological contaminants. These include bacteria, viruses, parasites, and protozoans. This can also include human or animal waste.


These contaminants are chemical elements with an unbalanced number of protons and neutrons, making the atoms unstable. These atoms can emit ionizing radiation. Some examples of these contaminants include cesium, plutonium, and uranium.


It may be hard to believe, but organic contaminants are some of the most harmful. Organic contaminants are carbon-based and often come from petroleum. These harmful water contaminants often bind to human tissue and can be extremely toxic and dangerous.

Inorganic Minerals

This group of contaminants includes minerals and toxic metals, and they can be naturally occurring. Some examples of naturally occurring minerals are calcium and magnesium. These minerals cause hardness in water which can affect the taste and cause other issues with your water. Other examples such as copper and lead can get into the water through erosion from the pipes. Some of these contaminants can be extremely dangerous such as lead and arsenic.

Radioactive Minerals

These contaminants are pretty much a subset of the inorganic minerals. The difference is these minerals are radioactively charged. These contaminants include radium, plutonium, and uranium.

How to Keep Your Water Safe

The first step to keeping your water clean and safe is knowing what is in your water. With a water test, you will be able to see exactly what contaminents are in your home’s drinking water. When you know your home’s specific needs, you will be able to take the necessary steps to make sure your water is at the quality that it should be.
