Abstract	Enhanced leachate recirculation (ELR) landfills are designed and operated for rapid waste stabilization, waste decomposition and increased rate of gas generation. The fundamental process improvement involved in the operation of ELR landfills is the addition of water and/or the recirculation of leachate into the landfill's waste mass. The study of moisture movement within Municipal Solid Waste (MSW) due to leachate recirculation plays an important role in developing the design and optimizing the operation of a leachate recirculation system. This paper presents the test results of moisture distribution and moisture movement within the MSW in an ELR landfill in Denton, Texas, USA. The study is performed using resistivity imaging (RI). The City of Denton landfill uses horizontal recirculation pipes for the water addition and leachate recirculation. A series of resistivity imaging tests were performed at the City of Denton landfill. First set of tests was performed along the recirculation pipes to identify the vertical moisture movement through individual pipes during recirculation. And then, second set of tests was performed across the recirculation pipes to determine the zone of lateral moisture movement due to horizontal leachate recirculation system. The preliminary results show that the moisture movement can be mapped using RI.
