Abstract:

The water quality used in Ejiao (donkey-hide gelatin) production is crucial to the final product quality. In 2023, the authors collected groundwater samples and analyzed the major anions, cations, and trace elements in the water samples to assess the groundwater quality in 11 Ejiao production regions of China. The main findings are as follows: The groundwater in production areas E, G, J, and K is classified as Class II water, while that in production areas F and H is classified as Class III water, indicating relatively poor water quality.. The dataset includes: (1) geo-location data of sample sites; (2) anion content measurements; (3) cation content measurements; (4) trace element content measurements. The dataset is archived in .shp and .xlsx formats, and consists of 9 files with data size of 15.5 KB (compressed into 1 file with 12.4 KB).
