Substance Overview: Ammonia
During this period, ammonia releases to land decreased by more than 50%. This drop was due to a facility that released high amounts to land in 2015 instead disposed of the ammonia in 2016, as well as a waste management facility reducing its leachate (leaking of ammonia from various waste materials to land) in 2015. Some waste products that ...
