New landfill technology for an old landfill`s problems: A case study
- EMCON, Indianapolis, IN (United States)
There are presently 111 solid waste sites in Indiana where 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 111 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 2 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. It has been the authors` experience that many old landfills without LCSs have problems with leachate breakouts on sideslopes. However, these same landfills are found to have good natural base liners and a low chance of contaminating groundwater. On the other hand, if an old landfill has no LCS, yet is not experiencing leachate breakouts on the sideslopes, the base liner may be suspect and leachate may be exiting the landfill bottom and into underlying groundwater. This paper presents a case study of an old landfill that, until recently, had no leachate control system. The landfill had experienced significant leachate breakouts on sideslopes except for one particular corner of the fill area.
