Practices for Pesticide Users
The best way to keep from contaminating groundwater is to follow label-
ing directions exactly. Be sure to note whether the labeling requires take any
special steps to protect groundwater. In addition, remember the following:

Keeping the use of pesticides to a minimum greatly reduces the risk
of groundwater contamination.
