Two entries. 10/08/2015 and 12/17/2015, were about the lead contamination of water in Flint, Michigan.
“A criminal investigation into this city’s water crisis reached into the top ranks of supervision over Flint on Tuesday [12/20/16] as Michigan officials announced felony charges against two former state-appointed emergency managers, accusing them of fixating on saving money rather than on the safety of residents.
The managers, who were appointed by Gov. Rick Snyder to lead Flint out of fiscal distress, were charged over their roles in the public health crisis prompted by the city’s switch to a new water source, as well as the delays in responding to residents’ complaints as they suffered the devastating effects.”
“The river water leached away protective coating inside the water pipes, leading to a dangerous level of lead, which can have permanent consequences on developing brain cells, in the water supply. Months went by before anyone warned the public.”
“According to a class-action lawsuit, the state Department of Environmental Quality was not treating the Flint River water with an anti-corrosive agent, in violation of federal law. The river water was found to be 19 times more corrosive than water from Detroit, which was from Lake Huron, according to a study by Virginia Tech.
Since the water wasn't properly treated, lead from aging service lines to homes began leaching into the Flint water supply after the city tapped into the Flint River as its main water source.
Health effects of lead exposure in children include impaired cognition, behavioral disorders, hearing problems and delayed puberty. In pregnant women, lead is associated with reduced fetal growth. In everyone, lead consumption can affect the heart, kidneys and nerves. Although there are medications that may reduce the amount of lead in the blood, treatments for the adverse health effects of lead have yet to be developed.”
This entry includes a timeline of the water contamination in Flint, Michigan.
This article also provides a timeline of the Flint, Michigan water crisis events.
This is a brief news story, but it’s an important update on the events. This could provide more information for a student discussion, or just expand your knowledge of the situation.
