There are some waters that contain larger amounts of iron 
than those just mentioned, but, on account of the presence in 
these waters of much sulfuric acid, the iron is usually consid- 
ered to be combined as iron sulfate. Aluminum sulfate is very 
often present in large quantities in these waters, as they may be 
formed by the decomposition and oxidation of shale containing 
pyrite. The latter on being oxidized furnishes both the iron 
and the sulfate ion. The excess of the sulfate dissolves the 
alumina in the shale. The following may be considered as 
typical waters of this class, and are classified as chalybeate by 
many authors:
