Can water be used as an arc quenching medium in circuit breakers?

Pure water isn't conductive. But keeping water pure while using it isn't easy. Also there is a little problem with electricity and water. Electricity will change 2H2O -> 2H2 + O2 add another spark you change it back into 2H2O but it also goes BOOM!

Oil used in some older breakers and SF6 used in newer (and noticeably smaller) breakers are used in transmission/distribution breakers to extinguish the arcs.
