MOUNTAIN HOME AFB, ID · 7,500 people served · EPA PWSID ID4200054

The bottom line

MOUNTAIN HOME AIR FORCE BASE (MOUNTAIN HOME AFB, ID), which serves about 7,500 people, has recorded 1 health-based drinking-water contaminant in EPA violation records since 2016, most notably Nitrate. Its most recent lead 90th-percentile sample was 0.0 ppb, within the 15 ppb federal action level. EPA's UCMR5 program detected PFAS 'forever chemicals' in this system: PFHxA (0.013 µg/L), PFHxS (0.01 µg/L), PFPeA (0.0067 µg/L). A certified water filter can reduce these at the tap — see the certified options for each below.

What the testing found

Measured levels from EPA violation records, compared to the federal limit (MCL). The black line marks the legal limit.

Nitrate

2.9× the federal limit
Measured 29 mg/L · federal limit 10 mg/L · latest 07/01/2020 · 12 violations since 2016

Causes 'blue baby syndrome' (methemoglobinemia) in infants under 6 months; MCL 10 mg/L as N. Runoff from fertilizer, septic, manure.

Lead

Not detected
Measured 0 ppb · federal limit 15 ppb · latest 12/31/2025 · 0 violations since 2016

No safe level. Damages developing brain/nervous system in children; linked to lower IQ, kidney and cardiovascular harm in adults. Usually enters water from corroding pipes/solder, not the source.

Filters certified to clean up your water

Your water shows Nitrate, PFOA, PFOS, PFAS. A refrigerator filter handles the most of this in one unit — these three are independently certified for the most of your contaminants (not marketing claims):

Want certainty about your tap specifically (not just the system)? A certified mail-in lab test is the gold standard — system-wide records can differ from your home's plumbing. Some links above are affiliate links — see our disclosure.

Sources & method. Contaminant levels and violations come from EPA's Safe Drinking Water Information System (health-based violations, 2016–present); PFAS from EPA UCMR5 monitoring (2023–2025). Levels shown are the highest recorded value in the violation records; a violation means the contaminant exceeded its federal limit at the system level. Your home's water can differ from the system average. Public domain data; we are not affiliated with the EPA.
