Analysis

What to know about Hartington's water

Hartington ranks #22 out of 200 cities in Nebraska for water quality, placing it above average in the state.

Hartington 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 0.35 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, Hartington may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
