Landfill: Pollution
The question
To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment she has made of the potential impact of leachate on the aquatic environment as a result of landfill abandonment.
Answered by Emma Hardy
We recognise the potential impacts and threats presented from leachates entering into the environment, such as Persistent Organic Pollutants (POPs), and per- and polyfluoroalkyl substances (PFAS), and the risks of these associated with abandoned landfill sites. Government is assessing options on ensuring that any environmental risks which stem from landfill sites, both current and former, are minimised.
Prior to a landfill becoming abandoned, a conceptual site model and hydrogeological risk assessment must be undertaken to identify any potential risks to the aquatic environment. These risks must be mitigated throughout the operational life of the site.
