"Snapshot'' Methodology for Estimation of Pollution Fluxes Under Different Flow Conditions

Abstract : To facilitate the mapping of pollution fluxes under different flow conditions when a limited number of gauging stations are available, a method relying on geographic data was developed to estimate the mean daily stream discharge at each sampling station. It has been tested on a rural river watershed that is located in northeast France (Madon River). The stretch of 100 km is equipped with three gauging stations. Surface water samples were collected at 30 stations under different flow conditions. In a participatory research project, samples were also collected by school children at one of the stations (once a week during the school year over a 2-year period). Dissolved organic carbon and nitrogen species were measured for all samples. These data illustrate the variation in the pollution in the river that is associated with agricultural activities and discharges of untreated wastewater. This method was used to obtain localized points of nutrient discharge, to identify the zones that favor nutrient removal, and to propose remediation work.
