Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

What You Can Do in North Haven

  1. Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
  2. Install a certified water filter. For Consumer Confidence Rule, listed in the water-quality records for North Haven: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
  3. Check your home's plumbing. With 78% of homes built before 1986, lead solder is a real possibility.
  4. Review your water system's CCR. If you use a community water system, request its annual Consumer Confidence Report for system-level test results or find it online.
