Assessment of the stability of tap water in the distribution system
The study involved monitoring tap water quality in a selected distribution system of 150 kilometers. The study aimed to identify changes in tap water quality during transport to the consumer's tap. As part of the monitoring, the physicochemical quality of water (including the content of metals...

| description | The study involved monitoring tap water quality in a selected distribution system of 150 kilometers. The study aimed to identify changes in tap water quality during transport to the consumer's tap. As part of the monitoring, the physicochemical quality of water (including the content of metals such as Zn, Fe, Mn, Ni, Cr, Cd, Cu, Pb) was assessed and the stability of the analyzed water was determined. Water quality was monitored at the outlet of the water treatment plant (WTP) and three collection points (POU). The results indicate that the water quality at each monitored point meets the standards for drinking water and its quality does not deteriorate during transport through the distribution system. The analyzed water was characterized by physical stability (turbidity <0.8 NTU) and chemical stability (the water had non-corrosive properties with a slight tendency to precipitate sediments), but it was not biologically stable (inorganic nitrogen > 0.2 mg N/L, phosphates > 0.01 mg P-PO43-/L and BDOC > 0.25 mg C/L). Bacteriological control of water did not reveal the presence of Escherichia coli. Higher concentrations of Zn, Ni, Cu, Cd, and Pb were observed in consumer taps than in WTP. |
