Between 10 and 20 million tons of road salt are used today on our nation's highways. This massive use of road salt has caused an alarming increase in the salinity of our water. This is a cause for concern not only because of the negative impact salt has on the environment, but because of the impact it has on our drinking water.
Across the Northeastern US, over 10 million tons of sodium chloride is applied to roadways annually. We also rely on salt to prevent falls on walkways and driveways. While useful for stabilizing slippery surfaces, salt use comes at a cost.
