The State of California has regulations in place to protect water quality in the Sacramento and San Joaquin River watersheds. The regulations focus on managing pesticide use to prevent harm to aquatic life in our streams and rivers. Such aquatic organisms include fish, reptiles, amphibians, crayfish, mussels, mollusks, and crustaceans.
Any chemicals used in our yard and gardens can be washed off directly into streams and rivers. It is best to use less toxic pesticides or other means of controlling unwanted pests, rather than harmful pesticides.

how pesticides get into our streams and rivers.
As part of this effort, this website provides information about pesticides, less toxic alternatives to control pests, and integrated pest management for residents and businesses. Small changes made around your home or business—something as simple as not spraying a pesticide on a windy day or addressing a pest issue without using pesticides—can make a big difference in our local water quality.
Pesticides and herbicides are used to control unwanted bugs and plants (“pests”) such as insects (ants, wasps), rodents (mice, rats), weeds, or other unwanted organisms. Although efficient, even when used correctly, these chemicals can cause harm to human health or have negative consequences within the environment. It is important to consider less toxic or other alternatives and always follow label instructions when pesticide applications are needed.
TAKE ACTION! Read the label of the pesticide you are thinking about purchasing and select the pesticide carefully. Ensure that it is appropriate for the pest and determine where you will use it.

In California, pesticides are regulated by the Department of Pesticide Regulation (DPR) as well as by the United States Environmental Protection Agency (USEPA). To learn more about why pesticides can be harmful and how they are regulated, visit the following websites:
