"The problem with Flint, and the problem with many water delivery systems throughout the United States, is that lead pipes are time bombs.
Like most metals, lead will break down over time, especially when it is exposed to corrosive water throughout its existence. When you have close to 1.2 million miles of lead pipes for water delivery in America — pipes that only have a lifespan of about 75 years and many are reaching that age — you have a recipe for disaster that experts warn will cost close to $1 trillion to fix.
The only reason that the crisis in Flint, Michigan, was brought to the public’s attention was because of one woman, a pediatrician named Mona Hanna-Attisha, who began noticing the symptoms of lead poisoning in an extremely large number of children from Flint. Dr. Hanna-Attisha went public with this information, which prompted investigations from civil engineers, leading to the unveiling of the problem. At the time of Dr. Hanna-Attisha’s discovery, the contaminated water had been flowing through taps in Flint for two years.
Sadly, Flint is just a tiny piece in a much larger story. Likely the reason the crisis in Flint made national headlines is because of the level of political incompetence that went along with it. But the story did wake people up to the idea that dangerous water could be anywhere, and that led to investigations by reporters who uncovered one of the potentially most overlooked stories of 2016."
