... to determine whether a landfill is causing contamination. However, if the mass flux of such elements is sufficiently less than surrounding natural or anthropogenic flux levels the environmental impact of the landfill may be significantly less than that based upon concentrations alone. The approach presented...

.... Constant head permeability test In order to grasp distribution of water flux out of the objected joint and to exa- mine whether Darcy's law is effective or not, constant head permeability tests at 3 different head positions (head above the surface level: h=46, =101, =105 cm) were carried out using borehole...
