· There were no environmentally
significant trends in water quality that could be identified
through visual examination of the data.
· Total aluminum, arsenic, cadmium,
organic carbon, chromium, copper, iron, lead, manganese, selenium,
and zinc at times exceeded water quality criteria for aquatic life
or drinking water due to high levels of suspended sediment during
high river flow. These substances were probably not biologically
available and would be removed by drinking water treatment needed
to remove turbidity.
· Turbidity removal and disinfection are
needed prior to drinking.
· The river was often too turbid for
recreation during the summer.
· The river had a low sensitivity to acid
inputs.
· Hardness levels were mostly above the
optimum range for drinking water, reaching the poor range during
winter.
· The water was cool enough for drinking
except during the summer, when it was warm enough for water-contact
recreation.
