Abstract
It is indeed important to monitor water quality in water-resource and raw water for water system entity. In particular, urgent response is required for sudden water pollution, therefore many water system entities put weight heavily on corresponding counterapproaches. Various counterapproaches are employed such as automatic fish monitoring system, oil film detector, oil content detector, full-automatic cyanogens analyzer, monitoring Volatile Organic Compounds (VOC) by using gas chromatograph, and monitoring hazardous material using UV measuring device since it is significantly important to keep damage to the minimum.
Among these sudden water pollution incidents, incident caused with oil could be the worst and devastative. If oil reaches to the core of water utility especially distributing reservoir, it will be harder to respond to such incident For this reason, this report states an oil counterapproach implemented by Hiroshima city as an example this time.
