The water you drink directly affects your immune system. Your body’s immune system is your first line of defense against diseases, therefore, it’s essential to make sure that you’re drinking water that’s safe for consumption.

Common Water Contaminants

According to the Centers for Disease Control and Prevention, about 7.2 million Americans get infected with water-borne diseases every year. The contaminants in tap water can pose numerous risks to your immune system and lead to several water-borne illnesses.

Perfluorinated compounds (PFCs)

These are man-made chemicals that penetrate the water bodies connected to public water supplies. PFCs may lead to a disrupted thyroid, increased cholesterol, and increased uric acid, and hypertension. PFCs can also reduce the production of immune system cells in human bodies.


Cryptosporidium is a microscopic parasite that enters the human body through drinking water and causes serious health effects such as severe diarrhea, cancer, and other intestinal diseases such as nausea, vomiting, and stomach cramps.


Safe drinking water contains approximately 4mg/lit or 4 parts per million (ppm) of chlorine. If the chlorine levels in your drinking water exceed this amount, it may increase your risk of cancer, asthma, and other respiratory issues. Typically, chlorine is used to kill harmful bacteria, but continuous exposure to chlorinated water may also affect your immune system negatively by killing harmful bacteria. Important Note: Contaminated water is especially harmful to people with weak immune systems. People at risk may include someone who has HIV or AIDS or is undergoing chemotherapy.

Water-Borne Illnesses

Water-borne illnesses are generally caused by drinking water that’s contaminated with pathogens or disease-causing microbes. Some of the most common water-borne diseases include;

Typhoid Fever

According to a survey, 20 million people suffer from typhoid fever every year globally. The disease typically spreads through unsafe water, contaminated food, and poor sanitation.


Cryptosporidiosis is a disease that spreads through contaminated water and causes diarrhea. Common symptoms of Crypto may include dehydration, fever, vomiting, weight loss, and stomach cramps.


Giardiasis is a diarrheal infection that’s marked by nausea, bloating, and stomach cramps. It’s one of the most common diseases in the US. It generally spreads through public water supplies, whirlpool wells, spas, and swimming pools. Common symptoms include fatigue, weight loss, gas, and bloating.
