Abstract

This study was conducted to estimate the water quality of agricultural groundwater well located in Buan-gun, Jinan-gun, Sunchang-gun, and Jangsu-gun of Jeollabuk-do. The groundwater samples were collected at 328 sites (Buan-gun: 158, Jansu-gun: 45, Sunchang-gun: 32, Jinan-gun: 93, respectively). We measured 4 kinds of general contaminants (pH, $NO_3-N$, $Cl^-$, and COD) and 10 kinds of specific contaminants (Cd, As, $CN^-$, Hg, phenol, Pb, $Cr^{+6}$, organophosphorus, trichloroethylene, and tetrachloroethylene). Generally, the level of general contaminants and specific contaminants in the agricultural groundwater was suitable for water quality standard in all sites for agricultural irrigation water. Exceptionally, chloride concentrations were exceeded water quality standard of agricultural groundwater at some sites in western coast area of Jeollabuk-do. Although water quality standards in agricultural groundwater have been suitable, the water contaminants of agricultural groundwater in western coast area were gradually increased than eastern mountain area.

전라북도 서부해안지역(부안군)과 동부 산악지역(진안군, 장수군, 순창군)을 대상으로 328 지점의 농업용 지하수 수질특성을 비교 검토하였다. 조사항목은 지하수법에서 규정하고 있는 농업용수 관리항목인 일반오염물질 4개 항목과 특정유해물질 10개 항목이었다. 전라북도 서부 해안지역에서 일반오염물질의 일종인 염소이온이 기준치를 초과한 지점이 나타났으나, 모든 조사지점에서 농업용 지하수 수질기준을 충족하였다. 특정유해 물질은 거의 모든 조사지점에서 검출한계미만 또는 자연함유량 수준으로 검출되어 안전성이 확보되었다. 농업활동이 활발하고 논과 밭의 경지면적이 상대적으로 넓은 해안 인접 평야지가 중 산간지대 보다 농업용 지하수중 오염물질의 농도가 더 높게 나타나는 경향이었다.
