| Topic | WQ: Ammonia (Un-ionized) in Americano Creek/Estero Americano 1988-1990 |
| Caption: The graph shows average, minimum, and maximum un-ionized ammonia concentrations measured in Americano Creek, and its estuary, Estero Americano, during 1988-1990. Sampling occurred generally monthly, with the number of un-ionized ammonia measurements at each station ranging from 8 to 27 samples for the monitoring period. Note that Stations E-1 through E-5 are estuarine. The reference value represents the San Francisco Bay Regional Water Quality Control Board (SFRWQCB) 1995 Basin Plan annual mean criterion for un-ionized ammonia of 0.025 mg/L (CRWQCB, 1995). Note that this watershed is actually within the jurisdiction of the North Coast Regional Water Quality Control Board, which has no objective for un-ionized ammonia. This monitoring was part of a water quality study of Americano and Stemple Creeks by Merritt Smith Consulting for the City of Santa Rosa and U.S. Army Corps of Engineers. See Picture for a map of the sampling locations and Info Links for more details. | |
