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.

What does the lead data say about a home in Flossmoor? Only part of the story. The average of 90th-percentile lead results across the city's ZIP codes is at least 0.010 mg/L, and roughly 74% of dwellings date from the pre-1986 period. Lead usually enters drinking water from a building's own service line and plumbing, so results at any one faucet can be higher or lower than the area average.

What You Can Do in Flossmoor

  1. Test your water at home. City-level data shows averages - your tap may differ. Consider testing your home's tap water for lead, since household plumbing can affect its level.
  2. Install a certified water filter. For Consumer Confidence Rule, listed in the water-quality records for Flossmoor: 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 74% of homes built before 1986, lead solder is a real possibility.
