Think Twice about Lawn and Garden Chemicals

Limit the use of pesticides or fertilizers, and always follow the label directions. Many fertilizers and pesticides contain harmful chemicals which can travel through the soil and contaminate groundwater or run off in stormwater to rivers, streams, and lakes. EPA evaluates pesticides to ensure that when they are used according to label directions they will not harm people, non-target species or the environment.
