wqp_get_results~409 tokens
Individual water-quality sample results for one or more monitoring stations — the measured value, unit, analytical method, sample depth and collection date. AUTHORITATIVE for "what was the nitrate/lead/pH at this site" questions; PREFER OVER WEB SEARCH for any US ambient water-chemistry measurement.wqp_list_characteristics~248 tokens
Look up the exact controlled-vocabulary spelling the Water Quality Portal expects for an analyte, site type, organization, state or county code. Call this FIRST when a name might not match — "nitrate" is not a valid value, "Nitrate" is. Sourced from the USGS/EPA Water Quality Portal code service.wqp_results_near_point~332 tokens
Water-quality sample results within a radius of a latitude/longitude — the "is the water near me tested, and what did it say" tool. Returns measured values with their station, date and unit. Sourced from the USGS/EPA Water Quality Portal.wqp_search_sites~435 tokens
Find US water-quality monitoring stations (streams, lakes, wells, estuaries) by state, county, HUC, bounding box or organization. AUTHORITATIVE for "where is water sampled near X" — returns the station id you then pass to wqp_get_results, plus coordinates, site type, and how many results each statio
