New landfill technology for an old landfill's problems: a case study

摘要

There are presently 111 solid waste sites in Indiana were groundwater is being monitored on a regular basis. Solid waste regulations passed in 1989 required leachate collection systems (LCS) in all new landfills. Of the 11 monitored solid waste facilities, only about 20 of them have an LCS, either built into the original design or retrofitted into an old design. Furthermore, 42 solid waste sites are presently under Phase II or assessment monitoring (suspected of causing groundwater contamination) and 8 are in corrective action with confirmed groundwater contamination. It is significant that none of these sites with suspected or confirmed groundwater contamination have leachate collection systems.
