Although climate warming-induced snow cover reduction, as well the development of ski tourism in hot and dry countries, is shifting industries toward use technical snowmaking, its raises hydrological, health-related, environmental concerns. This study was aimed at enhancing our current understanding impact snowmaking on environment human health. Culturable bacteriological indicators water quality (Escherichia coli, fecal enterococci, Salmonella, Staphylococcus), presence concentration antimicrobials, genes determining bacterial antibiotic resistance (ARGs), next-generation sequencing-based community composition diversity were examined from river water, technological reservoirs, five resorts. The number culturable bacteria prevalence most ARGs decreased during snowmaking. antimicrobial agents changed irregularly, e.g., ofloxacin erythromycin dropped process, while cefoxitin quantified only snow. altered through resulting survivability freezing temperatures or agents. Water storage reservoirs prior to allows us reduce ARG contaminants. Frequent thorough cleaning devices may aid reducing negative can have by contaminant input limiting disturbance ecological balance.
