Uranium hexafluoride is in Transportation Hazard Class 7 (radioactive) with a Subsidiary Risk in Class 8 (corrosive).
There are a great number of tests that can be performed on water to asses its chemical compositions. Typically, metal analysis is perfomed by AAS, pH, conductivity, chemical oxygen demand. A more specific question would allow for a more detailed answer.
