Delaware top concern

Sea-level rise, agricultural runoff

Delaware has the lowest mean elevation of any US state and FEMA NFHL coverage extends well inland in Sussex County. Agricultural runoff in poultry-heavy regions affects EPA SDWIS small-system nitrate readings. Lead-service-line inventories statewide are nearing 2024 LCRR baseline.

See Delaware state page for the full state-level rollup across all 12 dimensions.
