Abstract
The study presents an analysis of water quality monitoring in terms of the content of heavy metals, which is conducted in three independent water supply systems in Poland. The analysis showed that the monitoring of heavy metals isn't reliable - both the quantity of tested water samples and the location of the monitoring points are the problem. The analysis of changes in water quality from raw water to tap water was possible only for one of the analysed systems and indicate a gradual deterioration of water quality, although still within acceptable limits of legal regulations.
Highlights
The water crisis in Flint, Michigan [1], and the effects of it, has shown how important for tap water quality is stability of water, corrosion control and monitoring of heavy metals in Water Supply Systems (WSS)
The full analysis of heavy metal concentrations in the water distribution system was only possible for WSS1 (Table 4) because for WSS2 no heavy metals monitoring was carried out in the analyzed period, and in WSS3 all water quality monitoring points were located out of analysed system
Water quality monitoring was conducted with high variability over time and with low regularity, in relation to the number of tested samples
Summary
The water crisis in Flint, Michigan [1], and the effects of it, has shown how important for tap water quality is stability of water, corrosion control and monitoring of heavy metals in Water Supply Systems (WSS). According to World Health Organization guidelines [2,3], monitoring of heavy metals in drinking water has become one of the elements that have to be taken into account in estimating the risk to human health, and lead, in the International Program on Chemical Safety, is one of 10 chemicals important for public health [4]. This is related to the health risks that these contaminants carry. Release of this metals is associated with hydraulic conditions in system (age of water, velocity) and physical, chemical and biological parameters of water influenced on stability and corrosivity of water
