Can copper sulfate be a health hazard?

What are the biological effects of exceedingly high copper (II) sulfate concentration in the water supply?
Charles R. Vennes

You can find information about the toxicity of specific substances by searching for MSDS (Material Safety Data Sheets) on the Web. For example, a search for "copper(II) sulfate" on the Vermont SIRI MSDS database retrieved 40 entries. The first entry contained physical data and handling protocols for CuSO4, along with this:
