LeadMetalsZero ppb15 ppbAction level7/16/2024
Your body
EPA has set a health goal of zero for lead because no safe level of exposure is known. In children, low-level lead exposure has been linked to lower IQ, learning and attention problems; in adults, to raised blood pressure and kidney effects. Pregnant women and young children are most at risk.
Your home & appliances
Lead itself does not damage plumbing, but its presence is a sign of corrosion: water chemistry that dissolves metal from pipes, solder, and fixtures.
What it is
A metal that usually gets into tap water from lead service lines, lead solder, and older brass fixtures inside buildings, not from the water source itself. Homes built before 1986 are more likely to have lead plumbing.
Exactly as reported
- Lead 90th %: Zero ppb (90th percentile) · Action level 15 ppb · health goal Zero · violation: NO · sampled 7/16/2024

Your body
Exposure to certain PFAS, such as PFOA and PFOS, has been linked to effects including changes in cholesterol, reduced vaccine response in children, lower birth weight, and increased risk of some cancers (EPA; Fenton et al., 2021). In 2024, EPA set drinking water limits for several PFAS.
