Evaluation of the Effects of the Inland Pollution Sources after Rainfall Events on the Bacteriological Water Quality in Narodo Area, Korea

Abstract

This study evaluated the effect of the inland pollution sources on the bacteriological water quality in Narodo area after rainfall events. Following 16 mm of rainfall, the water discharged from Dohwa Stream and contaminants from Balpo village had a very limited effect on bacteriological water quality in adjacent area and the affected area did not extend to the designated area. In comparion, after 33 mm of rainfall, the density of fecal coliforms at stations located in the mouth of Dohwa stream and the discharg point of contamination sources located in Balpo village were lower than after 16 mm of rainfall. These results were obtained during an extreme high tide near the coast the contaminants discharged from Dohwa stream and Balpo village. Therefore, it is necessary to conduct a detailed survey to examine the dffects of tides on the diffusion characteristics of the contaminants discharged from Dohwa stream and Balpo village in order to manage of Narodo area efficiently.

Bacteriological quality evaluation of seawater and oysters from the Jaranman-Saryangdo area, a designated shellfish growing area in Korea: Impact of inland pollution sources

“…This is the pollution source evaluation method suggested by the US FDA in accordance with the equations presented below (Park et al, 2012). Thus, the degree of pollution was calculated, based on US FDA guidelines (US FDA, 2013), as the amount of water required to dilute the FC density to less than the standard level of 14 MPN/100 mL in seawater samples.…”

Seasonal variation of physicochemical factor and fecal pollution in the Hansan-Geojeman area, Korea

“…Evaluation method of pollution sources is suggested in the US Food and Drug Administration (FDA) in accordance with the following equations (Park et al 2012;Shim et al 2012). Thus, it is calculated as the amount of dilution water required that can dilute the FC density to less than 14 MPN/100 mL of the standard level in the seawater based on the US FDA guidance.…”
