Analysis

What to know about Lenox's water

Lenox ranks #15 out of 436 cities in Iowa for water quality, placing it one of the best in the state.

The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection.

Hexavalent chromium (chromium-6) was detected at 0.10 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, Lenox may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
