Ammonia

Ammonia is strongly associated with pollution being a common feature of sewage and levels are typically high in effluent. Levels below 0.3 mg per litre are considered as high ecological status for the river Swale. This is achieved in the average from all sample sites, however more than 37% of samples from Station Bridge and Brompton exceeded this limit indicating the variability and fluctuations present.
