Vanadium in water

For awhile it was part of my job to review results of water analysis for metals by ICP. I noticed that Vanadium was not detected in most water samples, and was surprised to see elevated levels in other samples. I researched where the Vanadium could come from, and for any known analytical artifacts or method interferences.
