Analysis

What to know about Western Springs's water

Western Springs ranks #661 out of 891 cities in Illinois for water quality, placing it below average in the state.

Western Springs 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.

PFAS compounds were detected in testing, though levels remain within current EPA limits. Residents seeking extra precaution may consider an activated carbon or reverse osmosis filter.

Hexavalent chromium (chromium-6) was detected at 0.04 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.

The system has seen 7 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
