Water. Turn on the faucet and it’s always there. Without it we perish. But how safe is our tap water? In this special report narrated by Joe Morton, NOVA investigates what happened in Flint, Michigan, when local officials changed the city’s water source to save money, but overlooked a critical treatment process. As the water pipes corroded, lead leached into the system, exposing the community—including thousands of children—to dangerous levels of poison. NOVA uncovers the science behind this manmade disaster— from the intricacies of water chemistry to the biology of lead poisoning to the misuse of science itself. NOVA follows ordinary citizens and independent scientists who exposed the danger lurking in Flint’s water and confronted those who turned a blind eye. And discover the disturbing truth that reaches far beyond Flint—water systems across the country are similarly vulnerable. How can we protect ourselves from poisoned water?

Poisoned Water.

Mason, stated in the discussion section of the papers, “…when I first came in contact with this process I was a very strong disbeliever; in fact, I am on record in print as not approving of the process. I have been converted, however…because of the results of many experiments. I found, very greatly to my surprise, that the dose was exceedingly small that was required to produce satisfactory treatment.” The full story of the chlorination of the Jersey City water supply…
