PROBLEM WTÓRNEGO ZANIECZYSZCZENIA WODY W WOJEWÓDZTWIE ŚLĄSKIM

In terms of bacteriology and chemistry, the tap water must meet the requirements for drinking water. Water utilities (waterworks) are required to constantly monitor the quality of supplied water. Test results posted on Department of Waterworks and Sewerage in Gliwice website confirm good water quality in Gliwice. However, before the water reaches our tap, it goes through the waterworks. When old pipes are found in the housing estate we live in or we live in a house where pipes have not been changed for many years, harmful compounds may appear in the water. In addition, tap water can be characterized by high hardness. This is the most common cause of stone formation, which further significantly reduces the tap water taste. To improve the quality of tap water, consumers use tap water filtering devices or buy bottled water. This article presents a survey using a random selection technique on a selected group of 200 middle-aged residents in the city of Gliwice in June 2019. The main goal was to present residents' opinions on the need to improve tap water quality.
