By entering your ZIP code, you can see a detailed report of the contaminants in your local drinking water. The database shows test results from 2014 to 2019, revealing information about chemicals, heavy metals, and other substances that may be present in your water supply.

The EWG Tap Water Database goes beyond just listing contaminants. It also provides health guidelines for each substance, helping you understand potential risks. This knowledge empowers you to make informed choices about your drinking water and take steps to protect your health if needed.

Understanding Water Quality and Contaminants

Tap water quality in the U.S. faces challenges from various contaminants. These substances can impact public health and may not always meet federal standards. Let’s explore the current state of tap water, common pollutants, and regulatory limitations.

The Current State of Tap Water in the U.S

Your tap water likely contains a mix of contaminants. The EWG Tap Water Database shows that many water systems have pollutants above health guidelines.

Some key findings:

  • Over 270 contaminants found in U.S. tap water
  • Many contaminants lack legal limits
  • Small water systems often struggle with compliance

Water quality varies widely across the country. Your local water report can give you specific information about your supply.

Common Contaminants and Public Health Implications

Several contaminants in tap water can affect your health. Here are some common ones:

  1. Lead: Can cause brain damage and developmental issues
  2. Arsenic: Linked to cancer and skin problems
  3. Nitrates: Dangerous for infants and pregnant women
  4. Chlorine byproducts: May increase cancer risk

Chromium-6, a known carcinogen, is also found in many water supplies. Long-term exposure to these contaminants may lead to serious health problems.

Regular testing is key to ensuring your water is safe to drink.

Legal Standards and Regulatory Limitations

The EPA sets legal limits for contaminants in drinking water. But these standards have some drawbacks:

  • Not all contaminants are regulated
  • Some limits are outdated
  • Standards don’t always reflect latest health research

The Safe Drinking Water Act requires updates to these standards. But the process can be slow.

Many health guidelines are stricter than legal limits. This means your water might meet legal standards but still contain unsafe levels of contaminants.

You can use water filters to reduce your exposure to harmful substances in tap water.

Resources and Guidance for Safe Drinking Water

The EWG Tap Water Database offers valuable tools for understanding and improving your drinking water quality. Learn how to use this resource effectively, find practical tips for safer water consumption, and explore ways to advocate for cleaner water in your community.

Using the EWG Tap Water Database Effectively

The EWG Tap Water Database provides detailed information about contaminants in drinking water across the United States. To use it, enter your zip code to see test results for your local water utility. The database shows which contaminants were found and at what levels.

Compare these results to EWG’s health guidelines. These are often stricter than legal limits. The database highlights contaminants that exceed these guidelines.

Pay attention to unregulated contaminants. These may pose health risks but aren’t subject to EPA limits. The database can help you identify potential concerns in your water supply.

Tools and Tips for Safer Water Consumption

Filtering your tap water is a good way to reduce contaminants. Choose a filter that removes the specific pollutants in your water. Carbon filters work for many common contaminants. Reverse osmosis systems can remove a wider range of pollutants.

Test your water regularly, especially if you have a private well. Home test kits are available for some contaminants. For more thorough testing, use a certified lab.

If using bottled water, check its source. Some bottled water is just packaged tap water. Look for brands that provide detailed quality reports.

For infants, use filtered water for formula. This helps protect them from potential contaminants that could affect their development.

Advocacy and Action for Cleaner Water

Stay informed about local water quality issues. Attend community meetings about water treatment and infrastructure. Voice your concerns to local officials and water utilities.

Support policies that protect water sources. This includes measures to reduce pollution from agriculture and industry. Advocate for stricter regulations on emerging contaminants.

Join or support organizations working for clean water. These groups often provide resources and organize community action.

Report any changes in your water’s taste, smell, or appearance to your water utility. This can help identify and address issues quickly.

Consider participating in citizen science projects that monitor water quality. These efforts can supplement official testing and raise awareness about water issues.
