There are no details in this article. It doesn't even state whether their water source is tainted or if it's a transmission issue. My house tested 16ppb for lead. Our source had no lead but a low ph which was leaching lead from the solder used on the pipes. An acid neutralizer brought the ph up and the lead dropped to zero.
