What to know about Springfield's water
Springfield ranks #499 out of 511 cities in Ohio for water quality, placing it among the lowest-rated in the state.
Springfield 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 0.30 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 11 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
