Corrosion in the lead and iron pipes that distribute water to city residents plagued Flint, Michigan since summer of 2014. The city decided to begin using the Flint River as its water source however it was not adequately monitored that water has the naturally ability to corrode iron pipes. So when high lead levels, rust-colored tap water, and the growth of pathogenic microbes the CDC stepped in.The Flint River water had a relatively low pH that decreased over time. Reports from the Flint treatment plant, the city’s water had a pH of about 8 in December 2014, but then it slowly dropped to 7.3 by August 2015. Environmental engineers say that if water pH drifts too low in the absence of orthophosphate, the water can start to leach high levels of lead from pipes.
This is still an ongoing crisis in Flint, it is dire that people across the country are aware of the dangerous that could come from your very own faucet. It's important to be updated on any decisions made based on the needs of a town because many people were unaware of the root of the problem.
