`searchUSDWFeatures`	USDW protection zones for UIC injection planning. Default areas (~189 polygons); pass featureType='boundaries' for ~5 fresh/saltwater interface lines.
`searchEarthquakes`	ODNR seismic catalog. catalog: instrumental \| historical \| both. Filter county/minMagnitude/yearFrom/yearTo.
`searchKarstFeatures`	Karst points (~46.7K). Filter county/pointType/bgUnit. POINT_TYPE has trailing whitespace upstream.

About

Ohio ODNR Division of Geological Survey (DGS). Probed 2026-05-02. Native server at agency data services, 14 data services in the catalog, 6 layers consumed: Ohio_Water_Wells/1 'Well Logs' (~651,613, the water-well log inventory; layer 0 'Sealing Reports' has ~46,789 abandoned reports but layer 1 is the primary inventory), USDW_Features/4 'USDW Areas' (~189 polygons, a UIC injection-zone protection analog; distinct values: Berea Sandstone=169, Lockport Dolomite=11, Sharon Sandstone or deepest sandstone unit above the Berea=2, Black Hand Sandstone=1, Black Hand Sandstone absent=1, Not mapped=5), USDW_Features/2 'USDW Boundaries' (~5 polylines, fresh/saltwater interface lines), Earthquakes_EB/4 (~1,181 instrumental epicenters since 1968), Earthquakes_EB/3 (~1,007 historical epicenters), and Karst_InteractiveMap/4 (~46,789 karst points). Spec drift caught at probe: searchMineralLocations was dropped because DGS_Services/agency-published returns HTTP 500 on every query (every where-clause variant attempted, both layer 0 and layer 0). The layer is broken upstream and this is documented in handler comments and getServiceInfo._droppedMethods. Upstream quirks: COUNTY_DESC on Water Wells is UPPERCASE ('DELAWARE', 'BELMONT'); WELL_USE_DESC top values are DOMESTIC=490,194, MONITOR=42,385, AGRIC/IRRIG=14,285, DEWATERING=3,318, INDUSTRIAL=1,748, COMMERCIAL=1,687, INJECTION/DISPO=478 (matched via UPPER LIKE). AQUIFER_TYPE_DESC has 200+ free-text values. Karst POINT_TYPE strings have trailing whitespace ('Spring - Field Verified ', 'Spring - Suspect-NotVisited'), which the handler trims. The Earthquakes_EB DATE column is epoch-ms while YEAR_/MO/DA are floats, so the handler returns both. maxRecordCount varies: water_wells=2000, USDW=1000, Karst=2000, Earthquakes=2000.
