Abstract
Considerable groundwater seepage has occurred in the Vulcan region of southwestern Alberta, and high salt concentrations have accumulated in the soil. A study of aerial photographs indicates that the extent of salinity is steadily increasing.Soluble-salt analysis of groundwater, soil and parent geologic-material samples suggests that bedrock, and to a lesser extent till, are the salt sources. Studies of groundwater movement, by means of a dye indicator, piezometers, and water-table levels in shallow wells, suggest both regional and local groundwater flow systems.There has been extensive soil salinization in the area; however, Solonetzic morphological features are not evident in all soils.
