Severe Pollution in Outer Waterways of Sudogwon Landfill Site... Exceeding River Environmental Standards by up to 7 Times
[Asia Economy Reporter Park Hyesook] A water quality survey of the outer waterways of the Seoul Metropolitan Landfill Site in Seo-gu, Incheon revealed severe pollution due to the inflow of wastewater from surrounding industrial complexes and agricultural areas.
On the 10th, according to the Seoul Metropolitan Landfill Site Management Corporation, water quality pollution was investigated monthly at 10 points along the outer waterways, excluding the winter season last year, for five parameters (pH, CODMn, SS, T-N, T-P).
As a result, the pollution level was most severe in the northern waterway of the 2nd landfill site, followed by the Wildflower Park, the eastern side of the 1st landfill site, and Anam Lake.
The chemical oxygen demand (CODMn) in the northern waterway of the 2nd landfill site was 4.1 times the environmental standard of 7 mg/L, and suspended solids (SS) reached 7 times the standard of 25 mg/L. CODMn levels in the Wildflower Park, the eastern side of the 1st landfill site, and Anam Lake exceeded the standard by 3.1 times and 2 times, respectively.
The pollution in the northern waterway of the 2nd landfill site was analyzed to be caused by discharged water from the nearby Geomdan Sewage Treatment Plant and Geomdan Industrial Complex wastewater final treatment plant, as well as strongly alkaline (pH 9~10) wastewater from construction waste intermediate treatment companies.
Additionally, in the outer waterway extending from the north to the east of Dream Park Wildflower Park, inflow of sediment and sewage due to the development of the Handeul District urban area was confirmed.
