Nitrate enters waterways from lawn fertilizer run-off, leaking septic tanks, animal wastes, industrial waste waters, sanitary landfills and discharges from car exhausts. Nitrates in water can cause severe illness in infants and domestic animals.
Ammonia is the decay product of animal proteins and is sometimes found in wastewater.
Through the process of nitrification, ammonia in wastewater is oxidized to nitrite and then to nitrate by bacterial or chemical reactions. 0.1 Preliminary Data - subject to revision Select on the parameter name to view all Ammonia time series plots on the basin map.
