These contaminants can affect the stream health, in different ways such as poisoning, destruction of habitat, and clogging of animals ’ gills. The need to protect our natural waterways is becoming increasingly important and different methods of treating stormwater are now available. The type of treatment depends on a multitude of factors, which includes: potential contaminant loadings, types of contaminants and land properties, such as climate and value
