Marc Edwards, a water corrosion expert and civil engineering professor at Virginia Tech, said in the report that he was "virtually certain" copper corrosion caused the green water. 

Edwards said in the report that "massive amounts of rust" can leach into the water from pipes during low temperatures. As the freeze begins to thaw, Edwards said water yanks free copper in the pipes and carries it through the faucet.

According to the report, the same action happens with rust in galvanized iron and steel pipes, which turns the once-frozen water brown.

Edwards said in the report that the best practice is to just let the tap run until the water turns clear, and that there are no health concerns.
