Abstract

The safety of drinking water has a direct impact on human health. In this paper, indicators of organic matterin the water stayed overnight and the water flow in two of the most common kinds of pipe materials-galvanized steel and PPR are analyzed experimentally, which indicates that the concentrations of TOC and CODMn in the overnight water are higher than those in water flow, and that galvanized steel pipes have a greater effect on the quality of water than PPR pipes. The results of GC-MS show that comparing to water flow, the concentrations of 6 sorts of organics increase and there are 12 sorts of new organics, and that the total peak area increases by 1704% in the overnight water in galvanized steel pipes, while the concentrations of 6 sorts of organics increase with 7 sorts of new organics, and the total peak area increases by 1660% in the overnight water in PPR pipes. The new added organics are mainly alkanes, olefins, alcohols and acids. For the residence time influences the quality of water evidently, it's advised to drink after taking appropriate measures.
