The United States is not alone in the battle to eliminate PFAS from farm soil and prevent contamination of these "forever chemicals" into the food and water supply. The UK, which also uses sewage sludge for fertilizer, is dealing with this problem as well. In other European countries such as Germany, Belgium, and the Netherlands, sewage sludge spreading on farmland has been reduced or banned.
This article from The Guardian, "‘A Trojan horse’: how toxic sewage sludge became a threat to the future of British farming", discusses the harm of PFAS to both humans and animals and the need for more regulation on using sewage sludge as fertilizer to help prevent these chemicals from getting to the food and water supply
Multiple hearth furnaces (MHFs) can be used to treat sewage sludge for removal of PFAS. These furnaces are able to get up to the temperature needed to destroy them. Learn more about MHFs being used for PFAS removal.
