Lead Exposure Risk Rating
Very High
Lead Exposure Probability

EPA model estimate based on housing age and infrastructure

77%
Note: Lead levels above are the 90th percentile from EPA monitoring — meaning 90% of samples were at or below this level. Even "undetected" tap water lead doesn't account for lead leaching from home plumbing. If your home was built before 1986, individual tap testing is recommended.
