SODIUM AND CHLORIDE LEVELS IN SOILS ADJACENT TO SALTED HIGHWAYS WERE MEASURED DURING JULY, OCTOBER AND APRIL AT 27 SITES TO DETERMINE THE EFFECT OF SALTING FOR PERIODS RANGING FROM 0 TO 18 YEARS. LEVELS OF BOTH IONS WERE RAISED AS A RESULT OF THIS PRACTICE, WITH THE EFFECT GREATEST AT THE EDGE OF THE ROAD EMBANKMENT AND ALSO WHERE SALTING HAD BEEN PRACTICED FOR THE LONGEST PERIOD OF TIME. SALTING INCREASED SODIUM AND CHLORIDE LEVELS MORE AT THE 6-IN. THAN AT THE 18- IN. DEPTH, AND SODIUM LEVELS WERE RAISED TO A HIGHER VALUE THAN CHLORIDE LEVELS. ALTHOUGH LEVELS OF THESE IONS WERE HIGHEST AT THE EDGE OF THE HIGHWAY, THE LEVELS WERE RAISED AT A DISTANCE OF 60 FT FROM THE HIGHWAY IN SOME INSTANCES. WALLS NEAR SOME OF THE HIGHWAYS CONTAINED CHLORIDE LEVELS IN EXCESS OF THE RECOMMENDED MAXIMUM. /AUTHOR/
