Al. 2001). These pollutants caused by urban areas contribute the deterioration of water quality in stream and runs which make up a significant part of the bodies of water in the state of Ohio. Water quality is crucial for the fish and macroinvertebrates species that can sustain a community in that specific body of water, any change in this quality can change the entire diversity and richness of the body of water and have implications further down the road whether it be positive or negative.

problem in Virginia streams with 39% stream miles. Mostly rainwaters carry sediments and soil particles into streams, lakes, and rivers, and then these particles are transported by flowing water. In other words, this stressor is one of the main forms of nonpoint source pollution, also do not have any water quality criteria. VDEQ uses benthic community to assess if there is any sign of sedimentation, generally. Main reasons of sediment inputs are erosion, improperly managed construction sites,…
