Also, they could try to input some sort of chemical substance that could kill the lead in the water, and they could put that in the pipes to kill the lead.

For tap water at the sink I would instal a filter that uses Activated Carbon so the lead can be easily absorbed. And the same would go for water fountains, and showers.
