U-High Creek Quality

The water quality of the U-High creek was excellent because it had pollution sensitive micro-invertebrates. However, not all creeks are this way. One example of humans polluting creeks includes farmers’ pesticides and fertilizers that soak through the ground and travel into the water (Lenntech, 1998-2016). These materials hold a lot of phosphorus and nitrogen which causes a surplus of algae. If this occurs, then the water could turn green (causing a low aesthetic value) and also once it breaks down, its’ bacteria will steal away the dissolved oxygen that the fish need to survive. Another example is the runoff of factory waste (Lenntech, 1998-2016). This waste brings toxins that could kill all the organisms and animals that interact with the
