초록
A study on the suitability for public water supply of the headwaters between Jamsil Submerged Weir andPaldang Dam, a 24km reach of Han-river, was carried out from June to October, 2005. To know the water quality of the headwaters 7 sampling points and a set of 23 physical, chemical and biological water qualityparameters for each sampling point were chosen. Each sampling point was sampled 4 times, distinctively fordry and wet seasons. The study disclosed the water temperature ranged 18.0~24.3oC, pH ranged 6.4- 8.8, dissolved oxygen ranged 6.8~10.9 mg/L, biochemical oxygen demand ranged 0.5~2.8 mg/L, total phosphorus ranged 0.032~0.204 mg/L, and total nitrogen ranged 1.50~5.10 mg/L. Total coliforms ranged 73~82,000 MPN/100 mL, fecal coliforms ranged 0~12,000 MPN/100 mL, and fecal streptococci ranged 0~3,100 MPN/100 mL. Chlorophyll-a samples were analysed to range 1.5~12.7 mg/m3 and algae samples showed their concentration ranged 68-1,100 count/mL. The analytical results showed that Acrylonitrile Butadiene Styrene (ABS), heavy metals, and endocrine disrupting chemicals were not detectable or below the detection limits.
Abstract
A study on the suitability for public water supply of the headwaters between Jamsil Submerged Weir andPaldang Dam, a 24km reach of Han-river, was carried out from June to October, 2005. To know the water quality of the headwaters 7 sampling points and a set of 23 physical, chemical and biological water qualityparameters for each sampling point were chosen. Each sampling point was sampled 4 times, distinctively fordry and wet seasons. The study disclosed the water temperature ranged 18.0~24.3oC, pH ranged 6.4- 8.8, dissolved oxygen ranged 6.8~10.9 mg/L, biochemical oxygen demand ranged 0.5~2.8 mg/L, total phosphorus ranged 0.032~0.204 mg/L, and total nitrogen ranged 1.50~5.10 mg/L. Total coliforms ranged 73~82,000 MPN/100 mL, fecal coliforms ranged 0~12,000 MPN/100 mL, and fecal streptococci ranged 0~3,100 MPN/100 mL.
