Abstract

The main goal of this study is to evaluate the wastewater treatment pods associated with socioeconomical and environmental factors of some Pontal do Paranapanema counties by means of an information set about supposed contamined areas. This study refers to the areas where the Teodoro Sampaio, Marabá Paulista and Regente Feijó wastewater treatment pods are located, which are susceptible to contamination due to lack of waterproof geomembranes (information from Public Attourney of Presidente Prudente-SP). Studying the local geomorphological patterns, water quality and soil permeability in the vicinity of the sewage treatment ponds is of capital importance in order to assess information about soil, groundwater or water stream contamination where dump is released. For that is necessary to perform analysis of permeability, water quality and soil grain size. Permeability analysis will be performed by use of a permeameter (portable and easy to operate) to assess the value of the saturated hydraulic conductivity, Kfs, "in situ". Water analysis will be performed by means of water quality index,WQI, which evolves chemical analysis to evaluate nine parameters. Grain size analysis from soil samples collected at the three sites will be performed at the Soil Laboratory of the UNESP, Presidente Prudente-SP. (AU)
