This study evaluated the water quality of Yeongsan River by multivariate analysis using the data collected during 2001~~2010. Water quality in Yeongsan River could be explained up to 75.2% by four factors, which were included in loading of nutrients (32.021%) and organic matters (17.453%), seasonal variation (14.775%) and microbes (10.951%). The results of cluster analysis were classified into three groups by factor 1 and 2, which has different water quality characteristics. Group 1 included sampling stations located in the upper stream and estuary dyke of Yeongsan River, group 2 included Gwangju 1 and Gwangsan affected by domestic sewage of Gwangju-cheon, and group 3 included sampling stations located in the midstream around the livestock farm and farmland.

This study has been carried out to clarify the characteristics of discharge and pollutant loading according to flow conditions at jiseok stream watershed (JSW). A flow rate and pollutant load in the study watershed were estimated by equation of stage-discharge and discharge-loads rating curve. By using the methods above, I`ve evaluated the water quality (WQ) of the JSW if it is satisfied with the standard target. I`ve collected the data of BOD and T-P from the JSW every 8 days for the duration of 12 months. And then, I`ve schematized the data upon the load duration curve and the results showed me that the WQ of JSW was satisfied with the standard target. I`ve also collected the same data every each day for the duration of 12 months from JSW and have schematized the data again. And the results showed that it also was satisfied with the standard target. To be concluded, I`ve determined that point pollution sources of JSW gives more significant impacts to the WQ than non-point pollution sources of JSW and hence, as time goes, point pollution sources will keep depriciating the WQ of JSW. Therefore, further efforts will be required to JSW to maintain the WQ.

본 연구에서는 영산강수계의 영본A 지점을 대상으로 평균 8일 간격의 실측된 수질과 유량자료를 이용 하여 유량 조건 별 수질특성을 평가함으로써 우리나라 오염총량관리 발전을 위한 기초 연구 자료를 제공하고자 하였다. 본 연구 결과를 요약하면 다음과 같다. This study was conducted to identify runoff characteristics of pollutants using flow duration curve(FDC) and load duration curve(LDC) in Youngbon A watershed during 2009~2011. A flow rate and pollutant load in the study watershed were estimated by equation of stage-discharge and discharge-loads rating curve. From these methods, BOD, T-N, and T-P have evaluated whether water quality standards would have attained. Results showed that BOD loads of about 50% plotted above the LDC, while T-N and T-P loads of about 50% plotted below the curve. It means that BOD of about 50% have exceeded the water quality criteria, while T-N and T-P of about 50% have complied with the water quality standards. Meanwhile, BOD, TN and T-P loads plotted above the LDC of low flows, implying that they were more affected by point pollution sources than nonpoint pollution sources in the study watershed.

자체방제계획서는 위험물질의 등급 주위환경의 피해, 사고대응계획 등으로 구성된 체계적인 관리제도이다. 자체방제계획서 작성지원 프로그램의 개발 목적은 사고를 예방하고, 사고를 제어할 수 있도록 안전관리 시스템을 각 시설에 제공하는 것이다. 이 프로그램은 MSDS(Material Safety Data Sheet), SOP(Standard Operation Procedure), ERP(Emergency Response Plan) 등 일반적인 안전관련 자료를 포함하고 있다. 자체방제계획서는 위험 확인, 평가, 예방 계획, 안전 분석 등으로 구성되어있다. 또한, 자체방제계획서 작성지원 프로그램은 정부 또는 관련 기관이 중소기업에서 발생 가능한 사고를 관리하는데 유용하다. Emergency preparedness plan (EPP) is the systematic management of activities that involve a material degree of risk of loss or other damage to the surroundings (people, property and environment), and the boundary of accident recovery plan (ARP). The main purpose of the program is to provide a safety management system to each facility in order to enable to prevent accident and to control accident immediately. The EPP includes not only typical safety-related documentations such as material safety data sheet (MSDS), standard operation procedure (SOP), emergency response plan (ERP). EPP is established basis of the preliminary safety analysis involving risk identification, assessment and prevention plans. The program is also helpful for government or related agencies to control a number of accidents in small-scale companies in the whole country.

The objective of this study is to evaluate and analyze Osu stream watershed water environment system. The data were collected from January 2009 to December 2011 including water temperature, pH, DO, EC, BOD, COD, TOC, SS, T-N, T-P and discharge. The data were used for principle component analysis and factor analysis. The results are as followes. The primary factors obtained from both the principal component analysis and the factor analysis were BOD, COD, TOC, SS and T-P. Once principal component analysis and factor analysis have been performed with the collected data and then the results will be applied to both simple regression model and multiple regression model. The regression model was developed into case 1 using concentrations of water quality parameters and case 2 using delivery loads. The value of the coefficient of determination on case 1 fell between 0.629 and 0.866; this was lower than case 2 value which fell between 0.946 and 0.998. Therefore, case 2 model would be a reliable choice. The coefficient of determination between the estimated figure using data which was developed to the regression model in 2012 and the actual measurement value was over 0.6, overall. It can be safely deduced that the correlation value between the two findings was high. The same model can be applied to get TOC concentrations in future.
