North Dakota DEQ environmental data. ND DEQ AGOL + FracTracker mirror; no auth. - searchSpills (~5.4K) ⭐ Bakken-era oil + brine spills (FracTracker mirror, 2014) - searchStormwaterPermits (~2.9K) ⭐ Bakken well-pad construction permits by operator - searchGroundwaterMonitoring (~278), searchImpairedStreams (~34.8K Cat 5 = 303d), getServiceInfo upstream quirks: ND DEQ does NOT publish spills/USTs/air permits/abandoned pits as Feature Services — methods reframed against actual surface + FracTracker spills. Stormwater has NO COUNTY column — filter silently dropped, use bbox/near. Brine + crude oil spill upstream is the same dataset (deduped by Incident_ID when spillType:'all').
