초록
This study was carried out to evaluate water quality based on physicochemical properties, including ammonium nitrogen ($NH_3-N^+$), nitrate nitrogen ($NO_3-N^-$), consumption of $KMnO_4$ and microbial indicators, such as total colony counts and total surveyed a group of 30 samples three times in 2005 (January to March, July to September, October to December). The mean concentration values of ammonium nitrogen ($NH_3-N^+$), nitrate nitrogen ($NO_3-N^-$) and the consumption of $KMnO_4$, were 0.01 mg/L (range 0.00~0.09 mg/L), 0.48 mg/L (range 0.00~3.31 mg/L) and 0.61 mg/L (0.0~3.42 mg/L), respectively. Based on the results, total colony count was detected in the ranges of 0~412 CFU/mL. In details, 84.4% of test samples was ${\leq}30CFU/mL$, 10.0% was 30~100 CFU/mL and 5.6% was ${\geq}100CFU/mL$. The detected rate of total coliforms was 6.6%. In conclusion, the ground water quality of 30 military facilities in Seoul, Kyunggi-do, and Inchon-city was acceptable for drinking except for a few detection of total colony count and total coliforms over standard.
