Research ArticleOpen accessIn the abstractHigh Density Groundwater Flow, Major-ion Chemistry and Field Experiments in a Closed Basin: Fuente de Piedra Playa Lake (Spain)Rodríguez-Rodríguez Miguel, Benavente Herrera José, Moral Martos FranciscoThis study presents the results of 10 years of field investigation in Fuente de Piedra Playa Lake located in southern Spain. These field observations along the playa's shore revealed evidence of a forced convective flow and the existence of density interface below the playa basin. An upward flux of groundwater from underlying formations could be a considerable part of its … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,310 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiological Activity of Methyl tert-butyl Ether in Relation to Soil Microorganisms has a Negative Environmental ImpactGholam H.S. BonjarFuel oxygenates are added to gasoline to enhance combustion efficiency of automobiles and reduce air pollution. Methyl tert-butyl ether (MTBE) is the most commonly used oxygenate because of its low cost, high-octane level and ease of blending with gasoline. However, due to its water solubility, high mobility and low biodegradability it leaches in soil subsurface at the speed of groundwater. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,665 accessesView PDF Cite
