Tap water quality regarding metal concentrations in Timisoara city, Romania

摘要

The aim of the study was to identify the risk prevalence of relevant metals in in-building installation systems in Timisoara City. In the study were collected more than 250 tap water samples in order to get an overview of the overall current contamination level of drinking water at the point of consumption. In the monitoring program were included three water plants, fifteen points from the control program of the company, thirty-three tap waters (first draw and fully flushed sampling procedure) and thirty-two tap water samples (random daytime sampling). The quality of drinking water produced by AQUATIM Company was in accordance with the European Directive 98/83/EC requirements. In samples collected from customer's tap the percent of non-compliance samples was around 50% in first draw, 10% in fully flushed and 25% in random daytime samples. The domestic distribution systems have an important influence to the quality of drinking water delivered by the AQUATIM Company.
