Anisotropic Oxidative Growth Of Goethite-Coated Sand Particles In Column Reactors During 4-Chloronitrobenzene Reduction by Fe(II)/Goethite

Reduction of nitroaromatic compounds (NACs), an important class of groundwater pollutants, by Fe(II) associated with iron oxides, a highly reactive reductant in anoxic aquifers, has been studied widely, but there...

Complete Genome Sequence of Azoarcus sp. Strain DD4, a Gram-Negative Propanotroph That Degrades 1,4-Dioxane and 1,1-Dichloroethylene

Azoarcus sp. strain DD4 can cometabolically degrade 1,4-dioxane and 1,1-dichloroethylene (1,1-DCE) when grown with propane and other substrates. The complete genome sequence of strain DD4 reveals a diverse collection of bacterial monooxygenase genes that may contribute to its versatility in degrading commingled groundwater pollutants.

A New Level of Understanding for Coastal Aquifers

New models of saltwater-freshwater mixing in coastal aquifers show how salinity varies throughout the year, with implications for what happens to groundwater pollutants before they reach the ocean.
