Methyl tert-butyl ether (MtBE) in deep wells of the Patiño Aquifer, Paraguay : a preliminary characterization

Abstract

Highlights • Groundwater concentration of MTBE, TBA and TBF were estimated in urban and rural areas. • Detectable concentration of MTBE are in areas of dense gasoline filling stations. • Large potential contaminant sources were correlated with detectable concentrations of MTBE and by-products. • MTBE and by-products were detected in high depths and at large distances from the potential source of pollution (b4000 m).
