Water is one of our most valuable natural resources, but it isn’t always as pristine as we might think. When water isn’t purified, it contains certain minerals, metals, and elements that can act as contaminants. The build-up of these contaminants when consumed can lead to serious health hazards. The drinking water supply in many parts of the United States including the St. Charles and St. Louis, Missouri, areas naturally contain these contaminants. Tap and well water passes through your water system along with the mineral components in that water. To avoid consuming these components and having to deal with health problems in the future, you need to purify your water.

If this sounds alarmist, allow us to show you how drinking water that isn’t purified can affect your health.

Common contaminants contained in unpurified water

Although these contaminants are naturally contained in water, drinking them can lead to unwanted health impacts on our bodies. Here are the contaminants that you may want to avoid in your drinking water:


The Flint water crisis1 has made it clear that lead contained in drinking water has dangerous health consequences. Yet, lead is a very common component of the drinking water supply in the United States. The water infrastructure2 around the US is also old, causing an accumulation of lead that may get into your drinking water. As authorities took action to quell the crisis by banning lead-based plumbing3, there were no requirements set for existing plumbing systems to be replaced. As such, most of the water mains around the country still contain lead. The long-term health risks of lead include kidney and liver damage, blindness, behavioral problems and slowed physical and mental development. With these health hazards lurking around the corner, taking an extra step to purify your drinking water doesn’t sound so bad now, does it?


Unpurified water also contains mercury. Mercury holds long-term health risks that include muscle weakness, loss of peripheral vision, impairment of motor functions including speech, hearing and walking, lack of coordination, and more. Mercury can impair children’s cognitive thinking, fine motor skills, memory, attention, visual-spatial skills, and more. Michigan residents have been warned against the intake of mercury released into Lake Michigan4 when they consume certain species of fish in the lake. If they can’t eat the fish, should they drink water from the lake? Purified water is a better choice. 


Chromium-6 has been receiving an influx of attention since the early 2000s, thanks to the movie Erin Brockovich, which specifically deals with the contamination of a town’s central water supply. Experts have found that millions of Americans are consuming this contaminant through their drinking water. The long-term risks include anemia, ulcers, reproductive damage, cancer, and kidney and liver damage. Just like those of the other contaminants, they are grievous. 


Radium is released into the environment and into the water by human activities like mining uranium and burning coal. It is a silvery-white radioactive metal and occurs naturally in the environment. Wells that are dug deep enough also naturally contain high amounts of this metal5. Radium can cause anemia, cancer, cataracts, fractured teeth, and even death.
