Avaliação do monitoramento da água do aquífero livre adjacente à Estação de Tratamento de Esgoto do Ribeirão Arrudas

Abstract

The posterior and prior knowledge of a aquifer taken from their natural state are foundations for effective monitoring, which has influence on decision making. Station Sewage Treatment Ribeirão Arrudas has two areas dedicated initially to the disposal of solid waste generated in the treatment of domestic effluents, with small contributions from industrial effluents. However, these areas had changed their destinations, and one was discarded and the other is serving transhipment for solid waste generated in the operation units of sewage from Metropolitan Region of Belo Horizonte MRBH. When necessary, temporarily receives the dewatered sludge generated at the station, and until this the year 2013 received, for treatment slurry originating from landfills. The monitoring of the unconfined aquifer, contained in these spaces, began in 2001 with the drilling of monitoring wells. Over time, periodicity and analyzed parameters were changed only given to some legal issues, imposed by the regulator. The evaluation of the unconfined aquifer monitoring performed in this work and suggests improvements need to allow an assertive and environmentally efficient management.
