Eight Simple Steps to Clean Water

Clean water starts with you- and me- and all of us.  Clean water is important to everyone in Maine.  Take a look around your home, your yard, your community, and you'll see many ways you can help clean up our waters.  We're all in it together - so here's how to get your feet wet!

First, a word about watersheds.  Understanding watersheds is key to helping clean up our water.  A watershed is the land area - much like a bowl - in which water is collected.  This water then flows by gravity to another body of water such as a stream, lake or ocean.  In Maine, we all live in a watershed and we all live downstream.

The culprit - polluted stormwater.  Together, Maine's industries and municipalities have done a great job cleaning up industrial pollution, sewer discharges and other major sources of contamination.  Now the main polluter of clean water is us.  Every time it rains, the rainwater washes off driveways, roofs, parking lots, roads, and other surfaces carrying with it contaminants to our streams, lakes, ocean, and groundwater.  Each and every one of us can help, and here's how.

1.  Use trees and shrubs to filter runoff.

5.  Maintain your septic system.

2.  Prevent soil erosion.

6.  Compost your waste.

3.  Keep your lawn small.

7.  Dispose of chemicals properly.

4.  Use less fertilizer. 

8.  Reduce, reuse, recycle.
