Study of Leachate Generated from Construction and Demolition Landfills

摘要

Construction and demolition (CD) waste landfills have largely been ignoredbecause they have been viewed as innocuous in comparison to municipal solid waste (MSW) landfills and hazardous waste landfills. Little is known about leachate generated from CD landfills because they have not been well studied. Based on the results of a statistical analysis, CD leachate chemicals could present a risk to human health and the environment because they exceed either primary groundwater standards, secondary groundwater standards, or guidance concentrations for groundwater. Despite the new regulatory attention paid to CD waste disposal operations, the basic question remains: To what extent does leachate from CD waste represent a threat to human health and the environment.
