Physical: The physical water quality parameters that were considered in the
monitoring program were temperature, PH, Secchi transparency and depth. Temperature
is indeed a fundamental factor for water quality, exerting a great influence
over the aquatic system. Factors such as reductions in water flow and waste discharges
may have a negative affect on its natural seasonal variability. pH is a known
standard measure of acidity and alkalinity. It drives many chemical reactions in
living organisms, where a pH value of 7 represents a neutral condition. These
parameters were measured in situ together with depth and transparency.
