Opis:
The use of polluted water bodies for recreation poses a risk of infectious diseases. This fact necessitates taking into account bacteriological indicators to determine the danger of recreational water use. The aim of the article was to develop a new method for assessing the potential risk to population health during recreational water use. A new method for assessing the potential risk to population health during recreational water use has been proposed, which combines the identification of potential risk according to chemical and bacteriological indicators. A new classification of water hazard levels according to the values of risk to population health has been developed. The value of the potential risk to the population health during the recreational use of 6 beaches in the urbanized territories of the city of Kharkiv and its suburbs (Ukraine) was obtained. It was established that bacteriological contamination has the probability of a very large impact on public health (hazard class 5). To compare the methods of assessing the risk to population health during recreational water use, the hazard index (NI) was determined according to the chemical indicators of the quality of water bodies in the city of Kharkiv. The use of the assessment of the potential risk to population health for the environmental regulation of the discharge of pollutants into a water body with wastewater is justified.

Opis:
The quality of Groundwater is characterized by physico-chemical parameters. They determine the way in which this water is used (water supply, irrigation, industry, etc.). This present study gives the highlighting of the hydrogeological and physico-chemical characteristics of aquifer waters in question resulting from the various wells, which aims to; gather, exploit and analyze the data, in order to determine their conformity with potability standards and their suitability for irrigation. Using multivariate statistical techniques including Principal Component Analysis (PCA), Hierarchical Cluster Analysis (ACH) and Diagram Analysis. They are applied to a dataset composed of 17 boreholes with 12 chemical variables over the entire study area, they were sampled in 2020. These boreholes are the principal water resources suppling Hassi R'mel w. Laghouat region in terms of drinking water and irrigation. Obtained results showed that the majority of groundwater in the Hassi R’mel region is hard; where approximately 20% of boreholes are characterized by fairly soft water, and approximately 5% are characterized by very hard water.
