Construction of database and distribution map of mineral components for natural Good-Water in Korea

Abstract

The database was established by conducting field surveys and water quality analysis of 877 water samples based on the national-scale various water sources, including 167 sampling sites from historically well-known hot springs, mineral waters, and spring waters (from August 2017 to June 2020). Spatial analysis using Kriging interpolation was performed to create a distribution map for 14 mineral components. The distribution maps were prepared with 50 m spatial resolution in raster type, and provided by Geo Bigdata Open Platform service of KIGAM. The spatial distribution of each mineral component showed some relationships with geological (lithology and fault) and regional characteristics, and could be used for drinking water and beverage industry (beverages, alcoholic beverages, teas, coffee, etc.) by providing the various information on the occurrence of natural Good-Water. We plan to continuously update information on Good-Water source to increase spatial resolution and secure its representativeness at each location.
