How You Can Help Protect Groundwater

It is everyone's responsibility who lives and works in the Protection Area to use chemicals responsibly to protect groundwater quality.

Non-regulated businesses and residents can help too by using and disposing of chemicals responsibly.

Specific ways that you can protect groundwater in your community are listed below. Or attend one of our many groundwater special events.
