Arkansas top concern
Flooding (Mississippi alluvial), tornadoes

Verdict
Across the 4 Arkansas ZIPs zipradar carries, 3 of the 12 dimensions carry measured values today: radon — all 4 in EPA Zone 3 (lowest); air quality — median day Good/Moderate across 4 with 2025 county data; drinking water — no health-based violations across the 2 matched to an EPA SDWIS system. The rest are per-ZIP lookups that populate as ingestion reaches each source — open a ZIP below rather than reading a state average.
