Description
This poster presentation presents research on the variations of disinfection byproduct (DBP) levels in waterbetween the distribution system (house entrance) and the consumer tap. The specificobjectives were: to evaluate the impact of water stagnation within house plumbing pipesover night on trihalomethane (THM) and haloacetic acid (HAA) levels; and, to evaluate the effect of heating water onTHM and HAA occurrence in hot tap water.Six residences (volunteers) of three different water distribution systems (two per system)were selected for the study. The waters in these systems have different historical levelsof THMs and HAAs. In each residence, eight sampling campaigns were carried outduring one year (every six weeks). During each sampling campaign, three types of watersamples were collected at each residence, including: water from the distribution system (faucetturned on for about 5 minutes); tap hot water (water from the heater); and, first drawn (thefirst water when the faucet is open in the morning). Sampling was conducted in theevening after the last use of water by the home owners (sampling for distribution systemwater only) and before any use of water early the next morning (sampling for firstdrawn water, hot tap water and distribution system water). In each collected sample,water quality parameters were analyzed.
