Earth Gauge Tip of the Week: Smart About Salt


During the winter months, salt and sand applied to our roads, driveways and sidewalks contribute to lake and stream pollution.  Fifty pounds of salt - one large bag - can pollute 10,000 gallons of water.  That's equivalent to one teaspoon of salt in a five-gallon bucket of water.

Viewer Tip:  Many cities and states are working to reduce salt use while still keeping streets and sidewalks safe.  Using less salt at home will help protect water quality in your neighborhood - and it will save money, too!
