Score Breakdown

Overall Home Safety Score: Score unavailable

Required evidence is missing. Missing values remain unknown and are not imputed or renormalized.

The score is withheld for this ZIP: a water system serving it has EPA UCMR5 PFAS results above the value of an EPA PFAS MCL (with compliance required from 2029), and the current score input does not include that system. We will show the score again once it is recalculated with that system's PFAS results included.
