Objectives: The purpose of this study is to evaluate the characteristics of leachate discharged from livestock burial sites in Gangwondo resulting from foot-and-mouth disease by monitoring the water quality at the survey tube-wells installed near livestock burial sites in order to investigate the effect of the leachate on the quality of nearby underground water and suggest a water pollution level in accordance with water quality evaluation criteria. Methods: To minimize the secondary environmental pollution damage caused by leachate at burial sites of livestock killed by foot-and-mouth disease, this study analyzed the leachate directly discharged from burial sites and installed survey tube-wells within 300 meters of livestock burial sites and investigated water quality as a means to ascertain the environmental effect of the leachate from the burial sites. In accordance with environmental management guidelines on livestock burial sites, this research investigated the water quality in the survey tube-wells in fifty five burial sites in Gangwondo. The elements investigated were $NH_3$-N, $Cl^-$, $NO_3$-N, conductivity, and E. coli. Water quality was monitored from 2011 to 2013. Results: The water quality from the drain pipe at the location of leachate from livestock burial sites showed BOD 37,209 mg/L, COD 8,829 mg/L, $NH_3$-N 3,633 mg/L, and $Cl^-$ 580 mg/L. According to the monitoring results of water quality ($Cl^-$, $NH_3$-N, conductivity) at the survey tube-wells, there was suspicion that 13 out of 55 burial sites discharged leachate, five sites discharged highly concentrated leachate (13%): one in Gangneung, one in Wonju, and three in Cheorwon. Conclusion: It was judged that out of thirteen observation wells which showed a possibility of discharged leachate, three survey tube-wells have established the discharge effect of leachate at burial sites up to recently. Therefore, it is judged that it is necessary to continue monitoring them and devise additional measures.

The effects of municipal sewage treatment plants on the water quality and effluent loading were investigated. BOD removal rates from Wonju, Hoengseong, and Hongcheon municipal sewage treatment plants were $88.9\%,\;80.6\%,\;90.7\%$ and T-P removal rates were $47.3\%,\;56.5\%,\;71.6\%,$ respectively. Also, BOD effluent leading from WonJu, Hoengseong, and Hongcheon treatment plants were 1,520 kg/day, 75 kg/day, 55 kg/day and T-P effluent loading were 203.9 kg/day, 4.2 kg/day, 4.0 kg/day, respectively. In terms of water quality distribution by distance of flow, BOD of the Seom river rapidly rose from 1.6 mg/l to 4.0 mg/l and T-P rose from 0.034 mg/l to 0.321 mg/l. Also BOD of the Hongcheon river showed a slowly rise from 1.1 mg/l to 1.4 mg/l and T-P from 0.011 mg/l to 0.026 mg/l. In conclusion, the effects of municipal sewage treatment plants on the water quality proved that T-P was higher than BOD. Consequently, in order to improve water quality, it is necessary to adopt an advanced sewage treatment system like nutrient removal.

According to the result of water quality examination, the average BOD of the area not affected by the cultivated land among the areas of the upper Naerin River was 0.47mg/l, and total phosphorous was 0.007mg/l; thus, it maintained the cleanliness level of Ia. The average BOD of the area with the alpine farmland was 0.52mg/l, which was similar to the one of the non-cultivated land. But total phosphorous concentration was 0.023mg/l, which was more than three times higher than the area belonging to level II due to the effect of fertilizer ingredients discharged from the cultivated land. About the loadings of the investigated area generated from each of the pollution sources, BOD was 878.5kg/day and total phosphorous was 79.7kg/day. Moreover, for the load density, BOD was $2.22kg/day.km^2$ and total phosphorous was shown as $0.20kg/day.km^2$. Regarding the rates generated from nonpoint sources like land among the loadings per pollution sources, BOD was 54%, total nitrogen was 91%, and total phosphorous was 73.4%. Therefore, it was shown that most of the nutrients were produced from the nonpoint sources. The level of BOD runoff loading in the Jaun River area, where nonpoint sources were mainly generated, was 37.1kg/day and total phosphorous was 1.33kg/day. The flow rates to the generated amount were estimated as 10.5% and 4.7% each.

There are a number of recreational facilities and large scale cattle farms around upper region of Song Stream, and they have raised concerns about the possible pollution of the stream. This study evaluated the extent of pollution at two segments of the stream to provide water quality data for efficient pollution source control. Stream flows and water qualities for three other small streams that flow into the segment No.3 of the Song Stream were also analysed, and these data were used to estimate pollution loadings from each stream. The estimated production pollution loading to the Song Stream were 3,079㎏ for BOD, 1,691㎏ for total nitrogen, and 176㎏ for total phosphorus. Of the total loadings, wastes from the cattle farms accounted for 79.8% for BOD, 50.8% for T-N, and 89.1% for T-P.

From 2014 to 2016, water quality of Youngrang Lake was surveyed, according to the location and depth. Following observations were recorded. Distribution of dissolved oxygen in the water depth was investigated at the middle section and the downstream 1st, 3rd, 5th, when investigating the bottom lm interval anoxic layer. The organic matter and nutrient concentration distribution was COD upstream 2.8 mg/L, middle section 4.2 mg/L downstream 4.1 mg/L, which was more than two times higher in the bottom layer. The TP concentrations showed a similar trend as the COD, being 0.047 mg/L at upstream, 0.051 mg/L in the middle, and 0.059 mg/L downstream. Difference in salinity was observed at every survey period; the lowest salinity recorded 28.5% during the second survey, and highest was 32.1% in the fourth survey. Korean trophic state index (TSIko) showed eutrophic conditions in the middle section and downstream, whereas mesotrophic state was maintained elsewhere during the entire period. In order to evaluate the cause of water pollution of the Youngrang lake, regression analysis determined the relationship between salinity and DO, COD, TN,TP, Chl-a; the results indicated R2 from 0.63 to 0.95. Youngrang lake water quality had a close relationship with salinity due to inflow of seawater. As a result,in order to improve the quality of Youngrang lake, efficient incorporation of the amount of water through the seawater influent is considered the key.
