  • An Investigation into the Water Quality of the Charleston Peninsula Storm Drains

    Since the late 1980’s, the South Carolina Department of Health and Environmental Control (SCDHEC) has expressed concern over extremely high fecal coliform counts found in several of the many storm drains that discharge from peninsular Charleston (City of Charleston, 1998). Although the City of Charleston is responsible for the fifty-plus storm drains, Charleston Water System wants to determine if ...

  • Are people willing to pay for river water quality, contingent valuation

    Now a day’s water pollution has caused incoveriences for people whom live near the Pavana river in Pune city, India. The river water quality has deteriorated by major water quality parameters like dissolved oxygen (DO), biological oxygen demand (BOD) and phosphates level. In present study it is tried to find people’s willingness to pay (WTP) for improvement of river water quality. Contingent ...

  • World emissions and economic growth: application of non-parametric methods

    The Environmental Kuznets Curve (EKC) hypothesises an inverse U-shaped relationship between a measure of environmental pollution and per capita income levels. In this study, we apply non-parametric estimation of local polynomial regression (local quadratic fitting) to allow more flexibility in local estimation. This study uses a larger and globally representative sample of many local and global ...

  • Level and transport pattern of faecal coliform bacteria from tropical urban catchments

    Urbanization and frequent storms play important roles in increasing faecal bacteria pollution, especially for tropical urban catchments. However, only little information on the faecal bacteria levels from different land use types and the factors that influence bacteria concentrations is available. Thus, the objectives of this study were to quantify the levels and transport mechanism of faecal ...
