This problem people suffered is connected to hydrology. And the question that might come up is how? it is because that water is in a watershed where there are a lot dirt rocks and even sediments that get into the oceans, rivers, streams and lakes. so the a thing called the source are the public water suppliers that happen to supply our drinking water. When the land is more developed we change the natural water cycle, so now when it rains it cant seep into the ground and so it travels as run off and in that process it picks up polutants when its on the way to rivers and streams. We all contribute to our waters.
The people have been trying to come up with a solution to the problem. They have had many solutions but only a couple will work. one of their ideas is to get a lot of purified waters for the people so that they can have clean waters to drink instead of drinking the poisonous water.
Since the crisis last year the water color changes from yellow orange to red. this affects their drinking water, their bath water, and their sink water.
In 2014, Flint, Michigan, drinking water was switched to the flint river. due to the insufficient treatment of water 100,000 residents were exposed to high levels of lead in their water.
