Abstract

Calcium chloride (CaCl2) and industrial sodium chloride (NaCl) are commonly used as deicing agents in Korea, which are expected to release dissolved chloride ions into the road surfaces following their application. This study aimed to comprehensively assess the usage of deicing agents and variations in groundwater quality between 2016 and 2022 by analyzing public data provided by various domestic institutions. Additionally, the study sought to identify factors contributing to deteriorating road conditions by comparing the amount of CaCl2 appied and the incidence of potholes. Pothole occurrences during the study period were primarily reported during heavy rainfall periods without application of deicing agents. In 2022, chloride ion concentrations in groundwater in the southeastern Korean Peninsula were significantly higher than in previous years, coinciding with severe cold waves and heavy snowfall that resulted in increased deicing agent use. However, further data collection and verification are needed to distinguish between the effects of seawater intrusion and deicing agents. Despite limitations in the completeness and consistency of public data, the research highlighted the urgent need for improved data quality and further field verification to fully understand and mitigate the environmental impacts of deicing agents.
