Landfill and water quality

Analysis: How low-discharge wells powered with solar energy may be useful for slowing plume growth

Unlined landfills often produce leachate that contaminates soil and groundwater. Leachate can also seep through small holes or tears in lined landfills. At breached landfills, timely and effective source control and aquifer remediation reduces pollution threats to nearby supply wells and other groundwater receptors. Preventing leachate plumes from moving offsite is a top priority for landfill managers. An approach to convert passive detection wells into low-discharge pumping wells, with the aim of stabilising narrow leachate plumes was evaluated by experts.
