Reducing roadway salt usage

An article in the StarTribune, A call for less salt in our roadway's diet, speaks to some of the problems salt causes in our lakes and ponds.  A study done by the Minnesota Pollution Control Agency discovered that a third of the metro area lakes are chloride impaired.  Once the salt runs off of the roadways it often goes into the sewer system and then into area streams and lakes.  Salt dissolves, but doesn not degrade. Once it is in the lake it is impossible to remove!

To learn more about road salt and water quality check out the Minnesota Pollution Control Agency's website.
