What was the cause of the water pollution in the Flint, Michigan city water supply?

Question

BlackTom AI · Accepted Answer

The central issue here is identifying the root cause of water pollution in Flint's supply. 
Option 1: 'Bacteria carried from the Flint River' – While bacterial contamination is a serious water concern, the Flint water crisis primarily revolves around chemical contamination from lead, not a bacterial contamination explanation. The switch to a Flint River source led to corrosive conditions for older pipes, which is not what this option states. 
Option 2: 'Lead that was corroded from the pipes carrying water' – This correctly describes the core problem: the new water source caused corrosion of lead-containing pipes, causing lead to leach into the drinking water, exposing residents to toxic levels. The chemistry of the water and the aging infrastructure are key factors here. 
Option 3: 'Mercury was transported from the Lake Michigan water source' – This is inaccurate. Mercury contamination was not the primary driver of the Flint crisis, and Lake Michigan was not the source involved in this situation. 
Option 4: 'Lead carried from the Lake Michigan water supply' – Also incorrect. The lead problem did not originate from Lake Michigan's water nor was Lake Michigan the source in Flint’s case; the issue was lead leaching from pipes due to the Flint River water and insufficient corrosion control. 
In summary, the correct explanation centers on lead leaching from corroded pipes caused by the water source change, while the other options either misidentify the contaminant, the source, or the mechanism of contamination.
