Analysis

What to know about Lagrange's water

Lagrange ranks #450 out of 511 cities in Ohio for water quality, placing it among the lowest-rated 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.

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 0.16 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 12 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Lead Within Limits
Detected: 0.0 ppb Limit: 15 ppb (EPA Action Level)

Well within EPA limits.

Copper Exceeds Limit

Where Lagrange's water comes from

Purchased Surface Water

Lagrange's drinking water comes primarily from surface water sources such as rivers, lakes, or reservoirs.

Surface water systems require multi-stage treatment including coagulation, sedimentation, filtration, and disinfection to meet EPA Safe Drinking Water Act standards.

These sources can be impacted by seasonal changes, stormwater runoff, upstream agriculture, and industrial discharge.

The system is operated by local government ownership and serves approximately 85,675 people through 4 water systems.

Frequently asked questions

Is Lagrange, OH tap water safe to drink?

Lagrange's water quality earned a grade of C (64/100). Some concerns have been identified. Consider a water filter for an extra layer of protection. The city ranks #450 out of 511 cities tested in Ohio.

What contaminants are in Lagrange's water?

Lead was measured at 0.0 ppb (90th percentile). 5 PFAS compounds were detected. 43 violations are on record.

How is Lagrange's water quality grade calculated?

The grade is based on four factors: violation history (40%), lead and copper levels (25%), PFAS contamination (25%), and regulatory compliance (10%). The score is also adjusted based on how complete the available data is. See our methodology page for full details.

Do I need a water filter in Lagrange?

PFAS compounds have been detected. A filter with activated carbon can help reduce exposure.

Where does Lagrange's water come from?

Lagrange's water is sourced from Purchased surface water. The city has 4 water systems serving approximately 85,675 residents.

What health violations has Lagrange's water system had?

Lagrange has 10 health-based violations on record. The most recent violation was recorded in November 2024. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 10 violations remain unresolved.

Why does Lagrange have so many PFAS compounds in its water?

5 different PFAS "forever chemical" compounds were detected in Lagrange's water supply during UCMR 5 testing. PFAS contamination often originates from proximity to military installations (AFFF firefighting foam), airports, industrial manufacturing sites, or wastewater treatment facilities. While detected, current levels are within EPA limits. An activated carbon filter can further reduce exposure.

How does Lagrange's water compare to other cities?

Lagrange ranks #450 out of 511 cities in Ohio (better than 12% of state cities) and #11693 out of 15744 cities nationally (26th percentile). The grade of C reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
