Abstract

ABSTRACT Fifteen storm events were monitored from April to October 2008 to investigate the stormwater runoff pollutant concentrations on a deciduous and coniferous forest in Korea. Based on the initial monitoring assessment, the average pollutant concentrations of stormwater runoff from the two forest sites were minor and not very significant in comparison to urban areas in Korea. In addition, the levels of pollutants from the forest sites were lower than the average stream water quality and could be considered as background concentration of forest sites. The results indicated that the pollutant event mean concentrations (EMCs) from the deciduous forest were significantly greater than the coniferous forest (p < 0.02) for all the measured pollutant parameters that include BOD, COD, DOC, SS, TN and TP; hence, not significantly different for TN (p = 0.16) and TP (p = 0.17). No correlations were identified between the pollutant EMCs and rainfall variables. The pollutant and flow patterns were used to provide ...
