Most new plumbing is done with plastic pipes (blue for cold, red for hot) that can be snaked and fished less destructively than metal pipes. While these don't contain lead, they may contaminate the water in unknown ways.

The type of plastic used for water pipes (cross-linked polyethylene, or PEX) has no known safety concerns as far as I am aware, mostly because it doesn't require added plasticisers. This is in contrast to PVC, which often contains phthalates and polycarbonate, which often contains bisphenols.
