Since purifying groundwater is very difficult after it already contaminated, efforts for management and preservation are highly demanded. In KOREA, Recently, Several problems about soil and groundwater have been brought up with management of livestock burial made from avian influenza(AI) and foot-and-mouth disease in 2010~2015. In accordance with relevant laws and regulations, monitoring wells are installed and water quality of the wells is measured periodically. The burials of livestock are sorted as a 3 grade according to result of the water quality analysis for the wells and some of them were under the detail investigation. In this detail investigation, a livestock burials in Neung-gugli, Korea is selected as target area which received water quality grade 1(Bad) and which is suspected of being leaked. Leakage is verified by soil analysis and clostridium perfringens(Maximum 110CFU/g) are detected. In groundwater quality analysis, high concentration of ammonia nitrogen(Maximum 1,136mg/L) is detected. In case of malodor investigation, concentration of ammonia and methyl sulfide gas from gas extracting pipe in the burial exceed Korean standards(Ammonia: 1.03ppm, C2H6S: 3.08ppm). As the result of Detail investigation, it is expected that leachate spread continuously to south direction of livestock burials in neung-gugli. But since the spreading range of leachate is used as non-agricultural land, it is considered that urgent measures are not necessary to prevent spread of leachate. Instead, installing and operating wells for water pumping after destroying the burial is expected more efficient.
