Fig. 4: Volatile organic compounds (VOCs) measurements: 3-methylbutanal.
From: Pilot-scale drinking water distribution system to study water quality changes during transport
Results for (a), 2,6-nonadienal (b), β-cyclocitral (c), methyl tert-butyl ether (MTBE) (d), chloroform (e), and butylated hydroxytoluene (BHT) (f). Whenever the reading was below the detection value, it was recorded as a zero. 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.
