Question
Can Nitrification occur in drinking water. What's the reason behind it?
(a) Yes, because in distribution system, where chloramines are used as secondary disinfectant, the presence of free ammonia can act as subtract for ammonia-oxidising microbes.(b) Yes, the addition of chloride ion to chlorine treated water acts as a controller of nitrification.
(c) No, Nitrification only occurs in plants.
(d) No, Nitrification needs some chemoautotrophic bacterias, which is absent here.

Solution
The correct option is D a, b
Nitrification occurs in drinking water during its treatment, as the free ammonia act as subtract for NH3 oxidising microbes.
