Analysis

What to know about Moro's water

Moro ranks #645 out of 891 cities in Illinois for water quality, placing it below average in the state.

Moro purchases its water from a regional wholesaler, meaning quality depends on both the supplier's treatment and the local distribution system's condition.

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.

As a small community water system, Moro may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

The system has seen 8 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
