In order to efficiently supply suitable irrigation water, We investigated water quality at 5 intake-towers out of 3,206 agricultural reservoirs in Jeollanam-Do from may to september. The overall water quality was found to show a good side, and water temperature increasingly tend to decrease by water depth. Cold-water damage is expected by the thermocline formed on water temperature reduces. which is possible to supply low-oxygen water in the present way. Intake-tower is only 2% in Intake methods of agricultural water in Jeollanam-Do. winches and hydrological scheme has accounted for 98%. To avoid the cold-water demage and get agricultural water in good state regardless of weather change or water level fluctuation, we suggest the introduction of buoyancy type intake apparatus which can get optimum depth location at each reservoirs. Also it is necessary to install the water measuring instruments which might to provide the useful information such as water temperature, water level and turbidity in real time. They also would automatically adjust the height of the water intake.

To investigate the water quality of the Lake Jangseong, samples were collected 4 times during this study period at five stations each season. According to the inflowing stream loading, BOD loading was caused to land, human activity and fish farm sequentially. COD, T-N and T-P were contributed to fish farm, human activity and land sequentially. The Lake Jangseong had the characteristic of high algae growth rate according to long hydraulic retention time and low mean depth(9m of mean depth, 0.76year of hydraulic residence time). The amount of phosphorus accumulated was 5.2㎏/d. The excessive critical loading was 2.10tP/yr. The actual inflowing 8.36tP/yr, showing 4 times higher than the excessive critical loading. The water quality of the Lake Jangseong was transparency 1.4m, water temperature 13℃, pH 7.3, DO 6.9㎎/ℓ, COD 4.2㎎/ℓ, SS 5.1㎎/ℓ, T-N1.104㎎/ℓ, T-P 0.070㎎/ℓ, chlorophyll-a 17.5㎎/㎥. The water quality value was the highest in the fish farm(L2) by sites and high in winter, fall, summber, spring sequentially.

Desalination plants in South Korea were installed with government aid from the mid-1990s. Furthermore, most of the plants were small scale to produce under 100 m3/day. Generally, brine produced by desalination plants was recognized as being twice as concentrated as seawater. Also, the discharging of brine into the ocean can have adverse impacts on the wider environment and marine ecosystem. However, many of the domestic desalination plants used low-salinity groundwater, so low-salinity brine with salt concentration lower than seawater was produced. The largest number of desalination plants in Jeollanam-do have been installed and operated in Sinan-gun. The average total dissolved solids of feed water in 13 low-salinity desalination plants was 821 mg/L. The capacity of low-salinity desalination plants was from 6 m3/day to 300 m3/day. The desalination plants on Jara island and Ock island were invested as the oldest low-salinity desalination plant in Shinan-gun. 13 low-salinity desalination plants used 1,588 m3/day of low-salinity groundwater. And 691 m3 of low-salinity brine was released from desalination plant for a day. This study investigated the characteristic of low-salinity brine in Shinan region and analyzed water quality to compare groundwater quality standard. In addition, growth rates and mineral contents of microgreens(Brassica oleracea var. gongylodes, Raphanus sativus L., Hordeum vulgare) were evaluated using low-salinity brine. The total dissolved solids of low-salinity brine was 1,975 mg/L, which was about 2.2 times higher TDS than feed water. Moreover, the brine meets the needs for the water quality standard as microorganism, organic matters, heavy metals, agricultural pesticides, volatile organic compounds in 「Groundwater Act」except for chlorine. However, chlorine standard could not be applied according to the exception clause, so brine could be used as domestic water, Agricultural water and etc. The growth rates of Raphanus sativus L. growing low-salinity brine were higher than general groundwater. Furthermore, mineral contents of micro-greens could be increased when the higher salinity brine was used. The results show a need for greater support and improved public relations are needed to reuse low-salinity brine in island areas.
