Abstract
The aim of the study is to assess the quality of water from selected recreational fountains in Ciechocinek and Inowrocław health resorts. All analyzed water fountains are characterized by seasonal changes in their discharge. The exceedance of biochemical oxygen demand and chemical oxygen demand values found in the water samples may indicate water contamination with compounds of organic origin getting from the external environment to the basin of the fountain or too little recirculation of water. A significant improvement in water quality was noted in fountains in which water exchange occurred due to, for example, its failure. In addition, the water was characterized by a relatively high content of general hardness and conductivity. Reported exceedances of water quality parameters disqualify it for direct human consumption. It does not meet the requirements for drinking water. It is recommended to introduce supervision over the quality of water from fountains by the bodies of the State Sanitary Inspection in the form of water monitoring in order to eliminate from the water compounds that may have a negative impact on human health. It is recommended to regularly use pre-filtration, chlorination and sodium hypochlorite in water in fountains to eliminate physical impurities.
Highlights
City fountains are precious elements of the natural environment, they perform a decorative function and enhance attractiveness of parks all over the world
The paper presents the results of research on selected physico-chemical parameters of water from fountains occurring in the cities of Ciechocinek and Inowrocław
Analysis of the results showed the variability of the water quality parameters in the four-month research period
Summary
City fountains are precious elements of the natural environment, they perform a decorative function and enhance attractiveness of parks all over the world. People use them to refresh, relax, interact with others and animals use them to drink water They make up a decorative and practical element of the environment and by lowering temperature they improve the quality of air. Contamination of fountain water involves presence of chemical substances which have an adverse effect on the air quality and are harmful to human health. Systems of water filtration are rarely disinfected so the circulating water is a site conductive to growth of pathogenic microorganisms posing a threat to human health. This can be caused by contamination in water reservoirs or inflitration in the pipes. The aim of the study is to analyze variability of physico-chemical parameters in fountain water situated in health resorts
