1. Water quality classification
A.: Water of good quality: city tap water, well water from stable
aquifer.
B.: Water of general quality: cooled circulating water, surface
water treated by sedimentation, and drained water treated by
effective deposition and completely biological treatment.
C.: Water of relatively poor quality: groundwater from aquifer of
poor quality, drained water treated by effective deposition but
with poor biological treatment, and surface water with enormous
microbes.
