A new method for removing lead from drinking water

Good news!

"... The new approach uses a process called shock electrodialysis, in which an electric field is used to produce a shockwave inside an electrically charged porous material carrying the contaminated water. The shock wave propagates from one side to the other as the voltage increases, leaving behind a zone where the metal ions are depleted, and separating the feed stream into a brine and a fresh stream. The process results in a 95 percent reduction of lead from the outgoing fresh stream. ..."
