LIMITING HIGHWAY SALT POLLUTION OF AREA WATER SUPPLIES

SODIUM CHLORIDE, PARTICULARY ROCK SALT USED FOR ROAD SNOW AND ICE CONTROL, IS BEING INVESTIGATED AS A CAUSE OF WATER POLLUTION. SALT CONCENTRATIONS IN STREAMS AND GROUNDWATER RESERVOIRS NOW ARE GENERALLY LOWER THAN THE 250 PPM LEVEL RECOMMENDED FOR DRINKING WATER STANDARDS, BUT, AS THE USE OF SALT INCREASES, CHLORIDE CONCENTRATION WILL APPROACH OR EXCEED THIS LEVEL DURING PARTS OF EACH YEAR. METHODS OF STORING AND SPREADING SALT TO MINIMIZE FUTURE WATER POLLUTION ARE DISCUSSED.
