Final answer:
Water testing protocols can provide accurate contaminant readings if properly implemented, but failures, as seen in the Flint water crisis, can lead to hazardous conditions and health risks for residents.
Explanation:
The protocol for testing water can lead to realistic contaminant readings if conducted accurately and under proper conditions. However, in the case of Flint, Michigan's water crisis, the failure to apply corrosion inhibitors led to lead from aging pipes leaching into the water supply, resulting in hazardous lead levels far exceeding safe limits. This situation exposed residents, especially children, to severe health risks and necessitated replacing the city's water pipes.
