Every time you turn on your faucet, you might wonder what’s really coming out of it. While the United States boasts some of the safest water supplies globally, recent findings show that water quality can vary significantly depending on where you live.
Understanding what’s in your water supply
The Environmental Protection Agency (EPA) regulates approximately 90 different contaminants in drinking water, including heavy metals, microorganisms, and pesticides. In 2024, they added new regulations for PFAS (forever chemicals), which affect an estimated 6-10% of public water systems nationwide.
How to check your local water quality
If you receive municipal water, your supplier must provide an annual Consumer Confidence Report (CCR). This document outlines any contaminants found above government limits and details actions being taken to address these issues. What if you never received yours? Contact your local water supplier or property manager – it’s your right to have this information.
Older homes face unique challenges
Homes built before 1986 require special attention. Prior to this year, building codes allowed lead pipes in construction. Even if your water supplier meets all safety standards, old plumbing can introduce contaminants into your water. Consider what would happen if your 1970s-era home suddenly started showing signs of pipe corrosion.
Geographic variations in water quality
Recent data shows dramatic differences in water quality across states. Hawaii, Alabama, and South Carolina report the lowest violation rates, while Alaska, New Mexico, and Louisiana struggle with higher numbers of infractions. However, these statistics don’t tell the whole story – a higher number of reported violations might indicate more thorough testing rather than worse water quality.
Taking control of your water safety
If you’re concerned about your water quality, professional testing provides the most accurate assessment. Many states offer free or subsidized testing programs. Well water users should be particularly vigilant, as they don’t receive CCRs and bear full responsibility for water quality monitoring.
Armed with test results, you can select appropriate filtration systems targeting specific contaminants found in your water. The EPA’s Safe Drinking Water Hotline serves as an excellent resource for understanding test results and identifying potential solutions.
Remember, water quality can change over time due to infrastructure aging, environmental factors, or updates to safety standards. Regular monitoring and testing remain essential for maintaining safe drinking water in your home. While most tap water in the United States meets federal safety standards, staying informed about your local water quality empowers you to make the best decisions for your household’s health.
