What do these numbers mean?

These Lead Results are in parts per billion (ppb). For reference, 1 ppb would be 1 part of lead for every billion parts of water (roughly one drop of water in an olympic-sized swimming pool). If the result is 0.5 ppb, this means the lab could not detect lead in the sample.

The results in red were above our remediation threshold. Finding lead sources takes time and can be complicated. You can see what remediation measures were taken in the Remediation column.

Check out the CDC's website to learn more about lead in drinking water.
