Here’s What to Do if You Drink Contaminated Water [2025]

Key Takeaways:

  • Contaminated water is any water that contains pathogens and chemicals that can make you sick.
  • Water contamination can be caused by several different factors, including agricultural runoff and corroded pipes.
  • Many contaminants found in tap water have no odor, color, or taste.
  • Knowing what to do if you drink contaminated water can help minimize the severity of waterborne illness symptoms you might experience.
  • The best way to prevent drinking contaminated water is to contact Tyent for a free water report and use a Tyent water ionizer—which features an advanced filtration system—to purify your drinking water.

Odds are, you do what’s necessary to avoid contaminated water during travel, such as only drinking factory-sealed bottled water, not swallowing water in the shower, and steering clear of the local ice cubes. Yet, many of us tend to forget that our tap water at home isn’t necessarily the best water to drink, either.

Even though the EPA states that the U.S. has one of the safest drinking water systems globally, drinking tap water isn’t worth the risk. The Centers for Disease Control and Prevention estimate at least 1 in 300 Americans get sick every year from germs in drinking water, with 40% of hospitalizations associated with drinking water exposures.

This article explores what contaminated water is, the signs and symptoms of water contamination, the common ways it can manifest, and exactly what to do if you drink contaminated water. Plus, we’ll cover the game-changing ways Tyent water ionizers can protect you from waterborne illnesses and make hydrating even healthier.

 

What is Contaminated Water?

Contaminated water -is any water that has been tainted by harmful substances, like chemicals and pathogens. When these substances enter a water source, that water becomes unsafe for everyday use, like drinking and cooking, and can make you sick.

Water contamination can be caused by:

  • Arsenic
  • Copper
  • E. coli O157
  • Enterovirus
  • Giardia
  • Lead
  • Legionella
  • Nitrate
  • Norovirus
  • PFAS (forever chemicals)
  • Radon
  • Rotavirus
  • Salmonella

Contaminants can get into your drinking water at the water’s source (where your tap water comes from) or while traveling through pipes to your home. The odds of contamination increase if the pipes your water travels through are cracked or if there are other problems with the water system infrastructure in your area.

Bottom line: Your local water quality affects your life, which is why it’s important to know what’s in your water and use a high-quality ionizer from Tyent to protect your health.

Signs and Symptoms of Water Contamination

Some signs of water contamination are obvious, especially if the changes to your water are sudden. Your water might:

  • Contain black particles
  • Feel like it burns
  • Have an oily or rainbow sheen
  • Look bubbly or foamy
  • Smell like manure, sewage, fuel, paint thinner, or rotten eggs
  • Stain plumbing fixtures black or brown, blue or green
  • Taste metallic
  • Turn your laundry black

However many impurities found in tap water have no odor, color, or taste, which makes them difficult to detect without an at-home water test.

Drinking contaminated tap water can cause a variety of mild to severe health issues. Some of the effects are more immediate, while others may take years to manifest. It depends on the type and concentration of germ or chemical in your water, how much you consume, and how long you’re exposed.

Chemical exposures, such as heavy metals and pesticides, can lead to severe health problems, including:

  • Abnormal heart rhythm
  • Cancers
  • Chronic pain
  • High blood pressure and hypertension
  • Nerve disorders
  • Organ damage
  • Reproductive problems

Exposure to pathogens like bacteria, viruses, and parasites, can trigger:

  • Body and muscle aches
  • Cough
  • Diarrhea (water, bloody)
  • Fatigue
  • Fever
  • Headaches
  • Jaundice
  • Joint pain
  • Kidney problems
  • Loss of appetite
  • Mouth blisters
  • Shortness of breath
  • Skin rash
  • Stomach cramps
  • Vomiting

 

What to Do if You Drink Contaminated Water

Anyone can get sick from accidentally drinking unsafe water. Here’s what to do if you drink contaminated water.

1. Seek Medical Advice

Some people are more sensitive to waterborne illnesses than others. If you have an underlying medical condition, are pregnant, or are over 65, you’re more likely to get sick if you drink contaminated water.

It’s always a good idea to check in with your doctor, who can help you identify the type of waterborne infection you have and prescribe a precise treatment to help eliminate it from the body, such as antibiotics, antivirals, or antiparasitic drugs. You should do so right away if you experience severe symptoms such as bloody diarrhea, excessive nausea and vomiting, or a fever.

2. Hydrate with Clean Water

As you navigate what to do if you drink contaminated water, one of the most important steps is maintaining adequate hydration to make up for the lost fluids due to diarrhea and vomiting. Drink plenty of water (from a trusted source, like a Tyent water ionizer) and electrolyte solutions, such as sports drinks. The darker your urine, the more dehydrated you are.

3. Identify the Source

Identifying the exact contaminants in your source water is a crucial step in preventing future waterborne illnesses. The EPA recommends getting your water tested through a state-certified water lab. However, it’s a costly option and it can take weeks before you receive your results.

Instead, you can receive an accurate water quality report from Tyent absolutely free. Tyent has water quality data for every major municipality in the country and can give you the contents of your drinking water within hours. Bonus: No water sample is required!

4. Contact Local Authorities

If you suspect or confirm that your drinking water is contaminated, you should contact your health department so the source of contamination can be located and controlled. They can also inform you of any additional steps you should take to decrease the risk of potential health problems.

5. Monitor Your Symptoms

If your symptoms remain severe despite supportive care (rehydrating, adequate rest, and proper nutrition), don’t go away within a few days, or you have a weakened immune system, see your healthcare provider as soon as possible. You might require IV fluids and further treatment.

 

What Causes Water Contamination?

Water contamination can be caused by several different factors. The most common causes of water contamination include:

Agricultural Runoff

Every time it rains, fertilizers, pesticides, and animal waste used in farming can wash away from farms and into nearby waterways. Agricultural contaminants usually contain high amounts of nitrogen and phosphorus, which encourage the growth of algal blooms (blue-green algae that can be harmful to humans and wildlife).

Industrial Discharges

A common by-product of industrial and commercial processes is industrial wastewater—the water that was used to make commercial products. This wastewater may contain harmful chemicals that, if not properly managed, can seep into the groundwater or enter the local water supply.

Sewage and Wastewater

Used water, such as water from toilets, sinks, and showers, becomes sewage and wastewater. The same goes for stormwater runoff, which is when rainwater washes road salts, oil, grease, and chemicals from the ground and into waterways. Roughly 80% of the world’s wastewater flows back into the environment completely untreated.

Old or Corroded Pipes

Over time, water delivery systems can degrade, with older pipes in particular corroding and leaching harmful contaminants into the water supply. Water that travels through these old, corroded pipes then carries these contaminants into your home—and, provided you’re not already keeping lead out of your tap water and other impurities, your drinking glass too.

Chemical Spills

Various industries use underground and aboveground storage tanks to store chemical substances. If a tank develops a leak, isn’t stored properly, or spills during transfer, the chemicals are typically diluted with water and then washed into the soil, increasing the risk of groundwater contamination.
