Concerning the healing of the protective layer in the pipes now that the water supply has switched back to Detroit, I read yesterday that this could take anywhere from 6 months to 2 years.

Is this a solution the city is looking at rather than the seemingly impossible option of replacing all the old lead pipes, and how safe would the water be afterward?

Thank you for the reply. Learning that there is a possibility the pipes may eventually recoat their protective lining has been the only glimmer of hope I've come across throughout this whole debacle.

I wonder if some pipes have been too damaged for even this, but I suppose we'll cross that bridge when we come to it.

Thank you for doing this AMA.
