TNO Bouw en Ondergrond Publication year 2009 Abstract Geophysical investigations were carried out on two modern landfill sites in the Netherlands. The objective of the geo-electrical and EM31 measurements was to reveal the effect of recirculation of leachate on homogenising moisture content in the waste to stimulate the process of attenuation. At Vlagheide, geo-electrical and EM31 measurements were done before and after 5 months of recirculation of leachate. The patterns resistivities are consistent between the geo-electrical lines and with depth. The geo-electrical and EM31 measurements both show an average decrease in resistivity after recirculation. This is possibly linked to a less heterogeneous moisture content caused by the recirculation process. At Kragge, the recirculation system is not installed yet. The geo-electrical profiles show a marked difference between the covered and open waste due to the HDPE foil on the covered waste. From the very high resistivities measured on the covered waste, it can be concluded that there are no significant leaks in the foil at the location of the measured geo-electrical line. On the open waste, the resistivity pattern shows a higher resistivity layer of a few meters thickness on a lower resistivity zone, which probably reflects differences in moisture content.
