5 Chemical variables (water quality) Good water quality is an important requirement for habitat integrity. , 1996). , 2000). Discharges of waste heat into receiving waters contribute to reduced concentrations of dissolved oxygen and the replacement of coldwater species by warm-water species. Both inorganic and organic solids occur in urban waters in high concentrations, contribute to high turbidity and cause many adverse impacts on habitats. Inorganic solids come from streambed erosion, which undercuts stream banks, causes the loss of riparian vegetation and sweeps away habitats (Booth, 1990; Urbonas and Benik, 1995).
