A collaborative approach to improve water quality by reducing the amount of chlorides reaching our local waterways.

Salt helps to keep our roads and sidewalks safe during the winter, but this salt often makes its way into our local rivers. While salt use is necessary to increase winter safety, Salt Smart works with municipalities, private companies and residents to use salt effectively while protecting water quality.

Resources specific to you:

Residents

Perhaps you'd like to know when to use salt on your driveway, how much to sprinkle on your residential sidewalk, or what those wet stripes are on the road that you see on your drive to work (anti-icing material!). Salt Smart supports residents in making informed winter maintenance choices.

Public Road Agencies

Do you operate a snow plow or supervise winter maintenance road crews? Salt Smart has resources and winter deicing workshops across multiple counties designed just for you and your staff. These resources focus on clearing roads with winter best management practices.

Private Contractors, Park Districts & More

Parking lot and sidewalk maintenance staff are making a difference by reducing chlorides reaching our waterways while ensuring public safety. Salt Smart has resources and winter deicing workshops across multiple counties designed just for you.

Why be Salt Smart?

  • Chloride levels are increasing in surface and ground water across Northeastern Illinois
  • The major sources of chlorides in Northeastern Illinois are road salt and to a lesser extent, water softeners
  • Road salt is necessary to maintain safer road and pavement conditions during the winter
  • Once chloride is in the water it is very hard and expensive to remove
  • Chloride impacts aquatic life: poor aquatic life scores dictate more stringent (and thus expensive) stormwater and wastewater regulations
  • Chloride is corrosive to infrastructure such as concrete roads and bridges as well as to the steel in our vehicles and around local business entryways
  • Chloride damages landscaping, from “salt burn” on foliage to increasing soil pH
  • Chloride can burn our pet’s feet, dry and crack them, and cause illness when licked off and ingested
  • There are many well accepted best management practices (BMPs) that communities can adopt that reduce the amount of salt used, while still maintaining levels of safety
  • These BMPs are good for safety, infrastructure, budgets, the environment and even our pets

Chloride Fast Facts

  • Rock salt (and table salt) is made up of sodium and chloride (NaCl) and measured in milligram/liter (mg/L)
  • Uncontaminated groundwater has ~15-50 mg/L of chloride
  • Average summer levels in Illinois is ~100 mg/L
  • Rivers tested in Illinois during the winter have ~300-2000 mg/L
  • 1 teaspoon of salt permanently contaminates 5 gallons of water
