· There were no
environmentally significant trends in water quality that could be
identified through visual examination of the data.
· Total aluminum, cadmium, iron, manganese and zinc at times exceeded water quality criteria for drinking water or aquatic life due to high levels of suspended sediment during high river flow. These metals were probably not bio-available and would be removed by drinking water treatment needed to remove turbidity.
· Turbidity removal and disinfection are needed prior to drinking water use.
· The river had a low sensitivity to acid inputs.
· Hardness levels were at or below the optimum range for drinking water in the summer, but above the optimum range in the winter months, reaching the poor range for short periods.
· The water was cool enough to be aesthetically pleasing for drinking, but too cold for water-contact recreation.
