Which of the following occurred because of Flint's water crisis? Select the three correct answers.
STatiana [176]

1, 2, 3

Because of Flint's water crisis;

  1. The number of children with lead poisoning doubled.
  2. General Motors stopped using Flint's water due to corrosion of their machinery.
  3. Dozens of people contracted a form of pneumonia known as Legionnaires' disease.

Explanation:

In a bid to save money, Flint City Council resolved to switch its water supply to the city in 2014 and also switching from the Detroit Water and Sewerage Department (DWSD) as a provider to Karegnondi Water Authority (KWA). During the process of switching, water from Flint River was used as a temporary source of water for the residents. This water was however not treated and caused corrosion of supply pipes which led to the leakage of lead into the water supply. The water was also filled with other mineral contaminants that made the water hard and later high levels of chlorine were detected. This also caused General Motors to stop using the water because it corroded its machines.

The levels of lead caused lead poisoning especially to children while dozens of adults suffered Legionnaires' disease a form of atypical pneumonia caused by<em>  Legionella </em>bacteria in the water. The city officials did not warn residents in time even after com0lanit of foul smell and redness of the water supply.
