69-14: Effect of Trace Metals on Stream EcologyThe demand for high quality water, such as drinking water, continues to increase, while the supplies of uncontaminated water dwindle. Many factors may render a water supply unfit for drinking water or the growth of an aquatic population. Among the water quality factors that determine the ability of a water to support life are the pH, temperature, the concentrations of organic matter (B. O. D. and C. O. D.), dissolved oxygen, dissolved solids,
