The purpose of this study was to investigate the changes of vitamin C and lactic acid bacteria count in Dongchimi used different kinds of water (distilled water, purified water, Cho Jung Carbonated Natural water). Dongchimi used different kinds of water was fermented at $10^{circ}C$ for 46 days. The changes of pH on Dongchimi used different kinds of water decreased in all samples during fermentation period, and then showed a slow decrease after 12 days of fermentation. The total acidity of Dongchimi used Cho Jung Carbonated Natural water arrived slowly at best tasting condition(0.3~0.4 point) compared with other conditions. The changes of salt content were ranked high one by one , Cho Jung Carbonated Natural water>purified water>distilled water during fermentation period. At early stage of fermentation, the changes of turbidity of Dongchimi used Cho Jung Carbonated Natural water showed highly as compared with other test conditions for 12 days of fermentation. Vitamin C content was measured high in Dongchimi used Cho Jung Carbonated Natural water during the fermentation period. Because calcium content was high in carbonated natural water, carbonated natural water had the highest calcium content during the fermentation period. The changes of lactic acid bacteria count showed the highest price at all experimental groups in 15 days of fermentation, but those of Dongchimi used Cho Jung Carbonated Natural water showed the highest price in 19 days of fermentation.
