The report states that Highwood previously exceeded the federal lead action level in 2024 tap sampling, with a 90th-percentile lead result of 76 ppb. It also reports two 2025 Lead and Copper Rule monitoring violations because required sampling was not completed during both 2025 compliance periods.

Does the City report tell me what is happening at my faucet?

Not by itself. The report describes the municipal system and reported monitoring. Conditions at a Highwood home can also be affected by its plumbing, service-line material, fixtures, and local conditions.
