Lawn and landscape maintenance: herbicides, pesticides and fertilizers
Nationally, one fourth of the pollutants found in rivers and streams originate from residential use of pesticides, herbicides, and fertilizers. These materials can enter into the storm drain system through illegal dumping, run-off from excessive lawn irrigation, and from heavy rains and from there they can be discharged directly into our waterways.
