3 methodsScheduledKansas Department of Health and Environment spills + USTs + identified-sites cleanup list + environmental-interest finder via maps.kdhe.ks.gov/kdhe_doe. - searchSpills ⭐ 32K reported spill events (status, county, medium, cause, dates) - searchTanks ⭐ 17K AST+UST facilities (FAC_STATUS, district, county) - searchIdentifiedSites ⭐ 3.7K cleanup sites across 13 BER programs (Brownfields, Superfund, VCRA, ...) - searchEnvironmentalInterestSites 40K KEIMS programs (USTs, LUST, ISL, drycleaner, ...) §0: Legacy host maps.kdhe.state.ks.us is dead (TLS cert mismatch). BER/Spills_DASC FeatureServer publishes 0 layers — handler uses Spills_viewer_public/0. KEIF L1 has no county column, only city.
5 methodsFreshness not declaredNorth Dakota DEQ environmental data. ND DEQ AGOL + FracTracker mirror; no auth. - searchSpills (~5.4K) ⭐ Bakken oil + brine spills (FracTracker mirror, static Dec 2013-Jul 2019) - 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, groundwater, impaired-stream layers have NO COUNTY column (county errors; use bbox/near). Oil + brine spill services are one dataset; spillType comes from reported volumes; operator matches Well_Name.

Spills + brownfields + NPDES + district lookup. - searchSpillsAndReleases (~16K, since May 2017) ⭐ filter county/product/district/year - searchBrownfields (~217 DERR TBA grants) ⭐ no county column — bbox/near only - searchNPDESPermits (~3.1K active individual permits) - getEPADistrict (point-in-polygon for OEPA's 5 districts) - getServiceInfo upstream quirks: Spills county + reportedproduct heavily space-padded; oepadist has 'NULL'/'CDO ' variants. NPDES permit_status only ever ACTIVE. All 3 native MapServers use lowercase `objectid` as OID. Brownfields layer has NO county column.
