Limits

Regulated
No federal MCL or action level on file
PFBS is regulated through a hazard index with PFHxS, PFNA and HFPO-DA rather than an individual MCL.Agency language as recorded in the contaminant reference.

Removal methods in the reference list: reverse osmosis, anion exchange. A method name is not a product certification.

By city: PFBS in Boise City drinking water, PFBS in Garden City drinking water, PFBS in Mountain Home drinking water, PFBS in Mountain Home AFB drinking water.

Not enough groundwater samples in the region to estimate PFBS in private wells. A lab test is the only way to know.

Numbers are the system's samples at its taps and wells, not yours. Lead and copper are 90th percentiles from sampled homes. Well pages are nearby-sample estimates. Health text restates EPA and DEQ. Methodology.
