Toelichting (Engels) Though coliform bacteria are used worldwide to indicate faecal pollution of groundwater, the parameters determining the transport of Escherichia coli in aquifers are relatively unknown. To investigate the effect of dissolved organic carbon (DOC) on the attachment of E. coli to saturated goethite-coated sand, we carried out column experiments with E. coli with and without humic acid (HA) in monovalent and divalent salt solutions. To characterize sorption of DOC and attachment of E. coli, we measured the pH of the influent and effluent, the cation concentrations and the zeta potential of particles.

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
