Water is essential for healthy living and is important in meeting with Agricultural, Industrial and Domestic needs in both urban and rural areas. It is a common denominator required by all classes of society. However, due to an overburden of population, unplanned urbanization and industrialization, the quality of water has gone through high levels of degradation caused by the release of contaminants, detrimental to human health, into waterways such as streams and Rivers (Kumarasamy, 2015). When pollutants enter into a water system, they cause distortions within the water body as it moves downstream. It is common to consider pollution to streams as being transported from industries and cities which release waste water into water courses such as lakes, rivers and streams through designated and established point sources. A bigger problem, however, actually comes from other unidentified sources where possibility of these contaminants being absorbed into the soil or transformed through natural processes before reaching the waterways is hindered by large impervious areas around the water body and short peak runoff times. Pollutants such as pesticides, oils, debris, nutrients, sediments, heavy metals, animal and human waste, transported by storm water runoff from fields, lawns, garages, agricultural settlements and unplanned settlements are deposited into the water body, contributing greatly to surface water pollution.
