Pesticides play an important role in agriculture and in maintaining our homes, lawns, and gardens. Unfortunately, pesticides are showing up where they’re not wanted — in our drinking water and our surface waters. If pesticides are not handled carefully, they can seep through the ground after a leak or spill, directly enter a well during mixing and loading, or drain to a stream or lake.
