which are not micro-organism (nitrite).

Sewage has a high nitrogen and phosphorus content, which can lead oxygen
depletion in the water, causing death of fish and other important animals and
plants

Key differences between acids and water.
bases?
A base is a substance that has a ph of more than 7, and less free hydrogen ions
than hydroxyl ions. Bases reduce the number of free hydrogen ions when added
to the water, causing an increase in ph.
