Analysis

What to know about Bucoda's water

Bucoda ranks #115 out of 294 cities in Washington for water quality, placing it mid-range in the state.

Bucoda 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 0.18 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, Bucoda may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
