Which agencies are responsible for regulating the use of pesticides in or on water bodies?

The Washington State Department of Agriculture (WSDA) and the Department of Ecology play crucial roles in regulating the use of pesticides in or on water bodies. The WSDA is responsible for the registration, labeling, and usage compliance of pesticides throughout the state, ensuring that they are used in a manner that is safe for both people and the environment. The Department of Ecology oversees water quality and ensures that the application of pesticides does not negatively impact aquatic ecosystems.

Together, these agencies enforce regulations that align with federal guidelines and state-specific regulations, thereby protecting water bodies from potentially harmful effects of pesticide use. This collaboration is essential in maintaining the balance between pest management and environmental protection in aquatic environments.
