Mismatch signals
Score: 56
- • surface-water impairment is present with no active hazard alerts in the cached feed
- • 7 impaired segments without any cached USGS stream gauges — under-monitored surface water
- • 7 impaired segments without any cached active permit pressure — enforcement gap candidate

Notes
- • Nearby surface-water impairment context is additive only; it is not a standalone verdict on county-wide harm.
- • NFHL political jurisdictions mapped: 6
- • Surface-water segments: 12 (7 impaired)
