        본 논문에서는 환경부에서 진행 중인 ‘지하수오염방지기술 개발사업’에 대한 경제성 분석의 기초자료로서 지하수오염 개선을 위한 일반가구의 지불의사액을 분석하고자 한다. 이를 위해 조건부 가치측정법(CVM)을 적용하되, CVM 연구에서 지켜야 할 다양한 지침을 엄격하게 준수하면서 가구조사를 시행하였다. 구체적으로 서울시, 인천시, 경기도 등 수도권 500 가구를 무작위로 추출하여 일대일 개별면접을 통해 '지하수오염방지기술 개발사업'에 의한 지하수오염개선을 위

        To examine water pollution status of agricultural water source of greenhouse area in Gyeongnam, the ground water quality was investigated six times at five areas in Gyeongnam from October in 1995 to March in 1996. pH of ground water were generally in the range of 5.9∼7.6. But a site in Changnyeong area was out of the range in 6.0∼8.5 which is water quality standard for agriculture. COD of ground water was below 8.0㎎/ℓ which is water quality standard for agriculture in all areas and the average was below 2.8㎎/ℓ. NH_4^+ -N contents in ground water was very low in all areas and the average of NO_3^- -N contents in Changnyeong and Chinju area was high with 13.2 and 11.5㎎/ℓ, respectively. Hardness, SO_4^2- and EC of ground water in Haman were higher than any other area. Fe and Mn contents of ground water in Kimhae were higher than any other area with 7.17 and 0. 95㎎/ℓ, respectively. Heavy metals such as Cu, Cd, Pb and Zn of ground water were below water quality standard for agriculture but some sites were over. Between COD and SS in ground water were not correlated with r=0.328, but between COD and NH_4^+ -N were positively correlated. And EC was positively correlated with Ca^2+, Mg^2+ and SO_4^2-. Ground water pollution status of agricultural water source of greenhouse area in Gyeongnam was generally high in order of Sacheon < Chinju < Haman < Kimhae < Changnyeong.
