Mineral constituents in water and their significance
T.B. Dover
1950, Open-File Report 50-69
Pure water does not exist in nature. Because water is a powerful solvent, every drop of rain water carries dissolved or suspended material - dust, pollen, and smoke, as well as the atmospheric gases, oxygen, nitrogen and carbon dioxide. When rain falls, the water running over the rocks and percolating...
