There is growing interest in groundwater resources to overcome the loss of surface water resources due to climate change. An understanding of the microbial community of aquifers is essential for monitoring and evaluating groundwater contamination, as well as groundwater management. Most microorganis...

지하수의 주요 오염물은 무엇으로 구분할 수 있는가? | 지하수의 주요 오염물은 무기물, 유기물, 그리고 미생물/미생물 기원 오염물로 구분할 수 있다(Table 1). 무기물은 주로 금속, 질산성 및 아질산성 질소 등이고, 대표적인 유기물은 자연유기물질(natural organic matter, NOM)이다. | |
대수층 인공함양의 수질 개선 원리는 무엇인가? | 그러나 지하수 과잉 채수로 인한 수위 저하와 고갈뿐 아니라 오염 관리의 어려움이 발생할 수 있어 기후변화에 대응할 수자원 확보를 위해서 대수층 인공함양 기술이 사용되기도 한다[13, 35, 36, 48]. 대수층 인공함양은 자원(강물, 빗물, 하수처리장 방류수 등)을 인위적으로 대수층에 주입함으로써, 수자원을 저장할 뿐만 아니라 주입한 물의 오염 물질이 저장되는 동안 자연 저감을 통해 수질이 개선된다. | |
지표수 이용에 어떠한 문제점이 있는가? | 지구 전체 담수의 약 98%에 이르는 귀중한 수자원인 지하수는 주요 식수원이 될 뿐만 아니라 농업이나 산업 분야에서도 이용되고 있다. 기후변화로 인한 지표수 자원의 손실이 커지고 지표수 저장시설을 통한 수자원 확보가 어려워지고 있다[35]. 또한, 도시화 및 산업화에 따른 지표수 오염이 증가함에 따라 지표수 중심의 물 자원 이용과 관리는 상대적으로 취약하다. |
