How to Test for Iron in Water | Hunker

Step 1. Pour water in a clear container and allow it to stand. An iron concentration of as little as 0.3 milligrams per l (mg/l) may be sufficient to produce reddish brown sediment. Iron is not generally harmful at this level, so an unhealthy level of iron in the water is easily detectable.

Iron (Fe) - Melting Point, Atomic Mass & Number, Chemical ...

Iron – Heavy Metal. Iron is a chemical element in the periodic table that has the symbol Fe and atomic number 26. Iron is a group 6 and period 4 metal. Iron is notable for being the final element produced by stellar nucleosynthesis, and thus the heaviest element which does not require a supernova or similarly cataclysmic event for its formation.
