Mineral content can be determined by a combination of several tests.

pH, hardness (usually Mg and Ca hardness), alkalinity ( mostly a carbonate test, dissolved CO2 and CO3), Total solids, Total dissolved solids, Fluoride and other anions and others by Ion Chromatography( IC), Cations, such as Calcium by IC as well. Most metals including Ca, Mg, Fe, Al, Pb, etc can be determined by Ion Coupled Plasma (ICP) You should find a local analytical laboratory that performs these tests. They can help you. If you do not require EPA certified analysis, the lab may be able to perform the test at less expense to you. The EPA has a home water testing fact sheet that may help.
