Lead Pipes

Milwaukee's Radical Solution to America's Clean Water Crisis

• Lead pipes were in use until 1986. Any home built before 1986 with no filter is putting lead in the water.

• "In Milwaukee, black kids in poor neighborhoods are four times more likely to be poisoned by lead." What's the source on this?

• Coalition of Lead Emergency in Milwaukee

• 5% of children under the age of six have lead levels above 5ug/dL - John Meurer, MD

  • key question: how much lead exposure leads to that kind of concentration?

• in lower income neighborhoods it's 15%

• what is the map of lead pipes in california?

• why is replacing lead pipes so grueling, slow, and expensive in the US? how have other countries dealt with this?

• apparently low tds water leeches lead from pipes. so whole house water filters that strip minerals can leech more lead.

Flint Water Crisis

Core issue: Flint switched from Detroit's treated Lake Heron water to Flint River water, which was more corrosive. The corrosive water leeched lead from pipes, causing widespread lead poisoning.

Normally cities use things like "corrosion inhibitors" to help this problem. These were not used.
