Inadequate record keeping has left councils unaware of whether former waste sites contain toxic substances. Over 100 old landfills in England have flooded since 2000, potentially creating serious safety risks. These sites, some of which may contain hazardous materials, are located adjacent to public parks and housing estates, impacting hundreds of households, according to an analysis by the Greenpeace-funded journalism website Unearthed, in partnership with the Guardian.
