Flint, Mich., is not the only city with lead pipes — and an ever-present risk of toxic contamination in drinking water.

Pretty much every American home built before 1930 was constructed with a lead pipe to carry water from mainlines under the street into the tubs, toilets and faucets inside — a legacy that now haunts the 100,000 citizens of that largely poor industrial town.

But unlike Flint, cities in Minnesota and most other places manage that plumbing heritage through a strict regimen of regulation, chemistry and monitoring.
