Many people worry about what is really in their tap water at home. Studies show that tap water can contain harmful contaminants like lead and PFAS.
In this blog post, we share what we found when we tested our own tap water and show you how to check your own. You might be surprised by the results.
Key Contaminants Found in Tap Water
Many people are surprised by what’s in their tap water. Common contaminants can make it unsafe to drink.
Lead
Lead is a heavy metal that sometimes gets into tap water through old pipes. The EPA says no level of lead in drinking water is safe. Even tiny amounts can harm children’s brains and slow their growth.
Adults may get high blood pressure or kidney problems from lead exposure. In our water tests, lead levels above 15 parts per billion mean the water is not safe to drink, based on EPA guidelines. Regular water testing and using certified lead-removing filters can lower health risks from this contaminant.
Arsenic
Arsenic is a natural chemical sometimes found in tap water. It can enter water from rocks, soil, or old farm chemicals. The EPA limit for arsenic in drinking water is 10 parts per billion.
Some areas in the United States still show higher levels, especially where well water is used. Long-term exposure to arsenic in drinking water can cause skin problems, cancer, and heart disease.
Kids and pregnant women face higher risks. Other chemicals like PFAS may also be in your water and pose new concerns.
PFAS (Forever Chemicals)
PFAS, also called forever chemicals, do not break down in water. Factories and firefighting foams often release them. These chemicals can move into tap water and stay there for years.
The EPA set a safe limit for some PFAS at 4 parts per trillion in 2023.
Even small amounts of exposure can be harmful over time. Studies link PFAS to cancer, liver damage, and problems with the immune system. People who use home filters or reverse osmosis systems may remove most PFAS from their drinking water.
Testing your tap water is important if you live near an airport or industrial area where these chemicals are common.
Nitrates
Nitrates are chemicals that can be found in tap water. They come from fertilizers, animal waste, and sewage. High levels of nitrates can be harmful to health. Infants are especially at risk.
Drinking water with too many nitrates can cause a condition called “blue baby syndrome.” This affects the blood’s ability to carry oxygen.
Testing for nitrates is important for safe drinking water. Regular checks help ensure the safety of municipal supply systems and home filters. Many utilities monitor nitrate levels, but it is wise to check your own tap water, too. Keeping an eye on these contaminants protects you and your family’s health.
Bacteria (E. coli and Total Coliform)
Bacteria can pollute tap water. E. coli and total coliform are two common types found in many areas. These bacteria often come from animal waste or sewage. They indicate that the water may not be safe to drink.
Drinking water with high levels of these bacteria can lead to serious illnesses. Symptoms include stomach cramps, diarrhea, and vomiting. Testing for these contaminants is important for maintaining water quality and safety at home.
Health Risks of Common Contaminants
Common contaminants can harm your health. Exposure to these substances may lead to serious illnesses over time.
Long-term exposure to heavy metals
Heavy metals in water can harm health over time. Lead and arsenic are two common heavy metals found in tap water. Long-term contact with lead can cause brain damage, especially in children.
It may also lead to high blood pressure and kidney problems for adults.
Arsenic exposure is linked to cancer and skin issues. People who drink water with arsenic may face serious health risks after many years. Reducing exposure to these heavy metals is essential for good health. Testing your tap water helps identify contaminants like these harmful substances.
Risks of PFAS on human health
PFAS, often called forever chemicals, pose serious health risks. These substances stay in the human body for a long time. They can lead to various health problems like cancer, liver damage, and immune system issues. Studies show that high exposure may harm development in children. Pregnant women exposed to PFAS can face risks too.
These chemicals enter water systems through spills or manufacturing waste. Many people get PFAS from drinking tap water or eating contaminated food. Regular testing for these contaminants is essential for public safety and health awareness. Reducing exposure helps protect yourself and your family from potential harm caused by PFAS.
Illnesses caused by bacterial contamination
Bacterial contamination can lead to serious illnesses. E. coli and Total Coliform are common bacteria found in tap water. These germs can cause stomach cramps, diarrhea, and vomiting.
In some cases, they may lead to more severe problems like kidney failure. Many homeowners are turning to water testing services to ensure their drinking water is safe and free from harmful contaminants.
Children and the elderly are especially at risk for these illnesses. Drinking contaminated water can result in dehydration and other health issues. Regular water testing is important to ensure our tap water is safe from harmful bacteria.
Taking steps to filter or purify your water helps protect you and your family from these health risks.
Solutions for Contaminated Tap Water
You can use carbon filters to catch many harmful particles. Reverse osmosis systems are another good choice for cleaner water.
Using carbon filters
Carbon filters are effective for improving tap water quality. They can reduce many harmful contaminants like lead and chlorine. These filters absorb impurities as water passes through them. Some carbon filters attach to your faucet, while others fit under the sink.
Using a carbon filter can also improve taste and odor in your drinking water. Regular maintenance is key; replace the filter according to the manufacturer’s instructions to ensure it works well. Carbon filtering offers a simple solution for cleaner, safer tap water at home.
Reverse osmosis systems
Reverse osmosis systems filter water to remove contaminants. They push water through a special membrane. This process separates clean water from impurities, like lead, arsenic, and PFAS. The result is safer drinking water.
These systems are effective for many homes. They are often installed under the sink or as whole-house units. Regular maintenance is important to keep them working well. Consider testing your tap water after installation to ensure it is safe and pure.
Regular water testing
Regular water testing helps keep your tap water safe. Tests check for harmful contaminants like lead, PFAS, and bacteria. Water utilities often test their supply, but that may not be enough for households. Homeowners should also do tests to ensure good quality.
Testing can reveal problems you might not see or smell. It ensures your family stays healthy and free from chemical exposure. Using a reliable testing kit is important for accurate results.
Regular checks help you take action if there are issues with your tap water safety.
Conclusion
We found some surprising things when we tested our tap water. Contaminants like lead, arsenic, and PFAS were present. These can harm your health over time. Using filters or reverse osmosis can help make your water safe. Regular testing is smart to ensure clean drinking water for you and your family.
