NO offense, this if old news
Don’t use hot water from the tap for cooking
Run the cold water a few seconds to flush lead deposits
The above is prior to the realization that additives to the water supply brought lead into home water.
Leadless ‘solder’ had been the norm for many years (including the auto industry).
If this is newsworthy concerning our Nations Capital, we’re in deep crap
The article said that chlorine was playing a part in binding lead to the pipes. The chlormination process released the lead to the water. It was in about the middle of the article.
This story has nothing to do with using hot water for drinking or failing to run water before drinking.
The new process actively released lead from the older plumbing systems. It is big news in any city with century-old homes. Unless you want to pay to replace all the plumbing in every older home, the water system has to work in a way to minimize harm to the residents.
Setting up a new water process without considering the impact on the residents is criminally negligent.
