Bacterial sanitation of farm water in suburb of seoul

In order to investigate the bacterial sanitation of farm water in the suburb of Seoul, we examined Standard Plate Count, coliform, E. coli, heat-tolerant bacteria, psychrophilic bacteria, Pseudomonas aeruginosa and Enterococcus of 86 farm waters in Kwangju-gun, Namyangju-gun Ⅰ and Ⅱ, Pajugun. The results were as follows : 1. Of the 86 farm waters, the average number of psychrophilic bacteria was 1400±350 CFU/ml, SPC 1000±300 CFU/ml, Pseudomonas aeruginosa 290±150 CFU/100ml, Enterococci 190±100 CFU/100ml, Escherichia coli 130±60 CFU/100ml, coliform 31±12 CFU/ml and heat-tolerant bacteria 13±5 CFU/ml, respectively. 2. Of the 86 farm waters, the sanitary bacteriological conditions of only 24 waters (27.9%) were sufficient to animal and human. 40.9% of waters in Namyangju I region were sufficient to animal and human, 33.3% in Paju-gun, 19.1% in Namyangju Ⅱ region, and 18.2% in Kwangju-gun. 3. Fourty five waters (52.3%) were detected the standard plate counts of over than 100 CFU/ml, 35 waters (40.7%) were detected coliform, 33 (38.4%) heat-tolerant bacteria, 16 (18.6%) Pseudomonas aeruginosa, and 15 (17.4%) were detected coliform and enterococci, respectively. 4. There were highly significant between SPC and psychrophilic bacteria (r=0.792), coliform and E. coli (0.728), E. coli and heat-tolerant bacteria (0.636), coliform and enterococci (0.462), heat tolerant bacteria and coliform (0.451), and E. coli and enterococci (0.369).
