· 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.
