Question

how did research conducted on polluted drinking water in flint, michigan, impact the environment? it resulted in the establishment of the environmental protection agency (epa). there was a reduction in the number of people getting sick. the amount of harmful chemicals in the water was reduced. there was an improvement in the quality of the air.

Explanation:

Research on Flint's polluted water aimed to address water - quality issues. Reducing harmful chemicals in water is an environmental impact related to the water itself. The EPA was established before the Flint water crisis. A reduction in sick people is a health - related impact, not an environmental one directly. And there's no direct link between Flint water research and air - quality improvement.

Answer:

The amount of harmful chemicals in the water was reduced.
