대수층 저장·이동 및 회수에 의한 음용수 생산과정에서의 위해사건분석

Abstract

Aquifer storage transfer and recovery (ASTR) is a type of managed aquifer recharge which entails injecting waterinto a storage well and recovering it from a different well. It has effects of natural purification when injected waterpasses through aquifer medium, and can be a good way of supplying water especially in a region with poor surfacewater quality. This study is about an on-going effort to introduce ASTR as a solution to source water problems in coastalareas. A pilot study is being conducted in the delta of the Nakdong River. A proactive management system is incorporatedto ensure the water qulity in the process of drinking water process. The system is based on the Hazard Analysis andCritical Control Point (HACCP) which is a tool originated from the food industry in order to assess hazards and establishcontrol systems for the safety of food product. In this paper, we analyze hazardous events which can occur in the entirewater supply system using ASTR as a first step to the incorporation of HACCP to drinking water production process.
