Did you know that there are more than 2,100 known drinking water contaminants that may be present in tap water? Considering the fact that a healthy person can drink about three gallons (48 cups) of water per day, it's a wonder why more people don't get sick from their tap water.

Fortunately, it's likely because there are water filtration systems available nowadays that can filter out some of these nasty contaminants. Though you may not think these water filtration systems are all that great of an investment, you might change your mind after you learn about the things that might be in your drinking water.


Cryptosporidium is a microbiotic parasite that gets in lakes and rivers through sewage and animal waste. Thanks to an outer shell, it can survive outside of the body for long periods of time, and it is immune to some chlorine disinfectants. Cryptosporidium can cause a mild gastrointestinal disease called cryptosporidiosis, which can prove to be fatal to those who have weakened immune systems. With water filtration systems, though, cryptosporidium won't be a thing to worry about.


Radon is a gas that can cause lung cancer, and accumulates in underground water sources, such as wells. Although it's more dangerous when it's in the air, drinking water contaminated with radon can increase a person's risk of developing cancer. In order to ensure that there's no radon in the drinking water, homeowners need water filtration systems.


Arsenic is another common contaminant that can cause skin damage or circulatory system problems. It can even increase a person's risk of cancer. Homeowners should invest in water filtration systems if their homes are near places where the water supply is affected by the erosion of natural deposits, runoff from orchards, runoff from glass, and electronics production wastes.

There's a reason why more than four out of 10 Americans use a water purification unit. With so many different, dangerous contaminants, it should really come as no surprise that so many homes rely on well water filtration systems.
