The presence and concentration of PFAS, also known as "forever chemicals," in fertilizing residual materials will be monitored under new standards in Quebec through a management code, according to Quebec's Environment Ministry.
Quebec's code on the management of fertilizing residual materials such as sewage sludge, also known as biosolids—which come from treating municipal or industrial wastewater—will take effect Nov. 1.
The code takes into account a total of 13 types of substances and includes monitoring guidelines.
