Stormwater runoff monitoring in a deciduous and coniferous forest

Desalination and Water Treatment (2012)

Marla C. Maniquiz Jiyeon Choi Soyoung Lee Lee-Hyung Kim

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 guidance to a more appropriate sampling method, i.e., collection of optimum number of samples at optimum time interval. Based on the concentration data and rainfall, the sampling time interval could be selected and used in the subsequent monitoring.

Physico-chemical characteristics of sediment accumulated in settling basin of a filtration best management practice

Desalination and Water Treatment (2010)

Soyoung Lee Marla C. Maniquiz Byungsik Lee Lee-Hyung Kim

Transport of constituents by stormwater runoff from paved surfaces in urban areas can directly affect the water quality of receiving waters and soils. Metal elements are the most evident constituents associated with particles found in stormwater runoff and the mitigation of its impact considers best management practices (BMPs). Physical treatment facilities such as filtration and sedimentation systems are typically applied to remove the particles and associated pollutants carried by the runoff. Hydrological characteristics of runoff as well as the physical and chemical characteristic of the particles influence the performance of BMPs. In this study, the size distribution of accumulated sediment and associated heavy metals in different particle size fractions generated specifically from the settling basin of a filtration BMP located at the Vehicle Registration Office parking lot in Samgadong, Yongin City, Kyunggi Province, Korea were determined. The highest fraction of particles collected from the basin was in the 425–2,000 μm size range. The greatest metal concentrations are higher with decreasing particle size fraction. X-ray diffraction analysis revealed that most of the particulates were originated from the pavement materials due to surface abrasion and transported by the stormwater runoff.

Diffuse pollutant unit loads of various transportation landuses

Desalination and Water Treatment (2012)

Marla C. Maniquiz Soyoung Lee Kyung‐Sok Min Joon Ha Kim Lee-Hyung Kim

ABSTRACT A four-year monitoring study was conducted to determine the diffuse pollutant unit loads for the six representative transportation landuses (i.e., highway, parking lot, bridge, service area and toll gate) in urban areas in Korea. Pollutant event mean concentrations (EMCs) were calculated from 123 storm events at eleven sites and the average annual rainfall and runoff coefficients were determined to estimate the unit loads using the National Institute of Environmental Research (NIER) method. Apparent differences in the unit load values existed among landuses as explained by the high variability of EMCs for different rainfall events. The study has found that runoff from bridges and highways contained the highest loadings of TSS and COD while service areas are the primary sources of nutrients and metals. The results of this study could be used by the Ministry of Environment (MOE) to separate the unit loads of transportation landuses from the urban area category in the current unit load system. The values obtained are also useful for planning and simulation purposes especially in the total maximum daily load (TMDL) programs and diffuse pollution abatement measures.

Appropriate determination method of removal efficiency for nonpoint source best management practices

Desalination and Water Treatment (2012)

Soyoung Lee Marla C. Maniquiz Lee-Hyung Kim

Abstract In Korea, best management practice (BMP) pilot facilities were installed to manage nonpoint source (NPS) pollution from the watershed areas. These BMPs are consistently monitored to determine the accurate pollutant removal efficiencies. However, the difficulty of removal efficiency determination in NPS BMPs is generally caused by uncertainties of site and storm characteristics. For that reason, removal efficiency determination has to apply appropriate method to eliminate uncertainties. In this study, the monitoring program was performed during 3 years in order to verify the efficiency of the infiltration trench during storm events. The pollutant removal efficiency was determined by four different methods namely the efficiency ratio (ER), summation of loads (SOL), regression of loads (ROL) and rainfall of frequency (ROF) methods. In comparison to other methods, the ROF method uses the rainfall frequency which is practical to eliminate uncertainties of NPS. Therefore, the ROF method is suggested as the appropriate method to determine the removal efficiencies and optimum among the four methods.
