CRD-C403-71 Test Method for Determination of Sulfate Ion in Soils and Water
This method of test covers determination of sulfate ion content in soil and water samples. The analytical procedure for water samples and for the extracts from soil samples is based on ASTM Designation: D 516, “Methods of Test for Sulfate Ion in Industrial Water and Industrial Waste Water.” The conductivity method for determining water-soluble sulfate in soil samples is based on that used at the U. S. Bureau of Reclamation.
