From: Pilot-scale drinking water distribution system to study water quality changes during transport

Results for (a) loop 1, (b) loop 2, (c) loop 3, (d) and the average density of the beginning, middle, and endpoint of every loop. Samples were measured online twice a day (AM and PM) during 7 days. Day 0 corresponds to the measurements after the cleaning of the pilot, after introducing the water in the loops. Loop 1 = red; loop 2 = green; loop 3 = blue.
