Contamination score

Higher = more contaminated vs. other cities.

Ackley is a small city in Hardin County in north-central Iowa's row-crop belt. No specific EPA or Iowa DNR violation was found for Ackley's water system itself. Iowa recorded more than double the nitrate-related drinking-water violations in 2025 versus 2024 (36 violations at 13 systems), driven by fertilizer runoff reaching shallow aquifers statewide, so agricultural communities like Ackley carry a real, documented regional nitrate risk even without a confirmed local exceedance.
