Flood debris management

In November 2021, large rainfall events known as atmospheric rivers caused flooding in the Sumas Prairie to Hope, Merritt and Princeton areas.

Floods have the potential to release and deposit contaminants into the environment. This can affect human health and the environment. 

The province is responding to these floods in several ways. This includes providing information and guidance on the environmental impact of these floods.
