I don't know where you live, but there are Federal Guidelines that municipalities must meet in order to provide safe water to residents. Go to the National Sanitation Foundations website (www.nsf.com) and you can get some idea of what the guidelines are.

Another item to keep in mind - with that high degree of iron levels in your water (indicative by the rotten egg smell) there is a chance that Iron Bacteria may be present. While in itself not a health hazard, it is like a carrier to many other items that should not be in your water. Cryptspuridium could be present. This is a know health hazard.
