Avaliação de contaminação de solo e água subterrânea por combustível fóssil em postos de combustíveis nas cidades de Cuiabá e Alta Floresta

Abstract

The risk assessment to the contamination of water supplies has been a management tool widely studied today, mainly due to water shortages, causing the man resorted increasingly to the use of groundwater for human consumption. A contaminant of groundwater, which has raised several discussions, are poorly soluble hydrocarbons in water. The aim of this study was to point out the need to implement public policies directed to the process of management of areas contaminated by gas stations in the state of Mato Grosso, as these contaminants are highly damaging to the environment and human health. The research was divided into three stages, where the first addressed survey the areas contaminated by gas stations in the city of Cuiabá, Mato Grosso, to discuss the importance of inventory for the management of these areas. The second step assessed the risk of aquifer contamination in the municipality of Alta Floresta, Mato Grosso, aiming to contribute to defining areas in need receive priority treatment for their protection or possible additional investigations, as well as the choice of best place for installations of supply wells or installation of a network monitoring groundwater quality. The third and final step was the isolation and characterization of degrading bacteria Diesel, found in groundwater samples collected at a gas station in the municipality of Alta Floresta, aiming to apply the bioremediation technique in contaminated areas derived fuel oil.
