Analysis

What to know about Bridger's water

Bridger ranks #12 out of 115 cities in Montana for water quality, placing it one of the best in the state.

Bridger relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.

Hexavalent chromium (chromium-6) was detected at 1.25 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.

As a small community water system, Bridger may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
