You find a chlorine demand occurring in your drinking water distribution system (series of pipes that carry drinking water throughout a city), yet there is no increased chlorine demand in the water going through the treatment plant, nor in the water being pumped into the distribution system.  What microbial mediated process do you suspect is occurring in the distribution system (pipes)?
