About this source
New Jersey Geological & Water Survey GIS (NJDEP ArcGIS, mapsdep.nj.gov). No auth. NE-US geology, aquifers, structural geology, recharge, and the 36 oil & gas exploration wells ever drilled in NJ. Two MapServers: Geology (bedrock/surficial geology, bedrock + surficial aquifer extents, faults, folds, recharge + sole-source aquifers, exploration wells) and Environmental_mon_gw (ambient groundwater-quality stations: metals/ions/nutrients/pesticides/radionuclides/VOC + USGS NWIS). searchExplorationWells/searchGroundwaterQuality return records or format:'geojson'; getBedrockGeology/getAquifers/getFaultsAndFolds/getGroundwaterRechargeAreas return polygon/line GeoJSON. Faults and recharge are dense — pass a bbox/near.

Technical detail for developers: parameters, pagination, units, and freshness per method.
searchExplorationWells
readNJ oil & gas / exploration wells by county/name or near a point (36 records).
EntitieswellgetBedrockGeology
readBedrock geology polygons by unit name or bbox/near as GeoJSON for a map.
Returns 10 generalized polygons by default; max 25. Use offset.
getAquifers
readBedrock or surficial aquifer extent polygons by name/location as GeoJSON.
getFaultsAndFolds
readFault and fold linework as GeoJSON (requires a bbox/near bound).
Required paramsbbox or neargetGroundwaterRechargeAreas
readRecharge polygons require bbox/near; layer soleSource may be returned statewide.
searchGroundwaterQuality
readAmbient GW-quality monitoring stations by analyte group + county/location.
