Introduction: Environmental issues caused by such human activities as farming, agriculture and infrastructural development can negatively affect the abiotic factors of the local environment. This can disturb water equilibrium and pose implications on the biodiversity of a watershed. Various forms of pollution, including runoff and erosion, can interfere with the health of its aquatic habitats. The purpose of this lab report is to observe to what extent the abiotic factors of Yellow Creek correspond with the health status of its ecosystem. This will be done by comparing the levels of turbidity and acidity and the corresponding level of impairment to four other water streams in the greater Toronto area. Research Question: How can the abiotic factors of a watershed such as acidity and turbidity indicate the health of Yellow Creek? Background information: Abiotic factors are nonliving, physical and chemical aspects of the environment. (Rutherford, 2015) The pH level is a quantitative measure of the hydrogen ions representing the acidity or alkalinity of a water solution. Aquatic life prefer water that has an acidic level of around 6.5-8.5 pH. pH levels higher than 8.5 become highly basic, while pH levels below 6.5 become highly acidic for water quality. This does not allow the species to regulate basic life-sustaining processes, primarily the exchanges of respiratory gases and salts within the water in which they live. BMIs (or Benthic Macroinvertebrates) are tiny animals
