This study was designed to investigate if there were groundwater contamination in 17 landfill where slaughtered animals were buried during the crisis of 2002 foot-and-mouth-disease (FMD) outbreaks in Gyeonggi province. From March to August 2005 groundwater was collected once a month from 17 sites, and examined with potential for hydrogen (pH), colour, turbidity, lead (Pb), arsenic (As), mercury (Hg), cadmium (Cd), copper (Cu), zinc (Zn) , iron (Fe), manganese (Mn) , aluminium (Al), nitrate-nitrogen , ammonia-nitrogen , microbial pathogen and Escherichia spp. In the examination of which of the mean concentration was from not-detected (ND) to 0.05 mg/l. The range of level was . However, groundwater from four sites was to go beyond the drinking water quality standard (DWQS), i.e., the mean concentration of those were . In the investigation of pH, colour and turbidity, all of the pH were below of DWQS (pH 5.8-6.6), but one site in color test and four sites in turbidity test were over the standard level. Among 9 metal ions examined, Mn was in excess of DWQS, and its concentration was . Pb, Cd, Hg and As were not traced. The contents of Cu, Zn, Fe and Al were , respectively. Escherichiae spp were not identified, but bacterial colonies were detected at 3 groundwater including 2 sites over the DWQS at the level of .
