Parameters used to determine the diffuse pollution index (IQApd) using the method of cooperative game theory

Abstract

The present work presents the methodology for obtaining the parameters and weights of the Water Quality Index of the Urban Surface Drainage for the Anhumas riverside, located in the city of Campinas, São Paulo. It is a method developed for a mixed system of urban drainage and wastewater depletion. This index will indicate the existence or not of the diffuse pollution contained in the urban surface runoff, determining the existence of a pollutant load. In this way, they were studied to determine which parameters and weights would be part of the Water Quality Index for Diffuse Pollution (IQApd), which will indicate the water quality of the urban surface runoff, at the exact moment of its collection. This number is acquired from the aggregation of physical-chemical, bacteriological and chemical data by means of specific methodologies. The advantage of this methodology is due to the fact that it synthesizes in only a number of parameters, facilitating its interpretation when compared with individual indicators and with little expressiveness.
