following officers consistently dismissed statements that Flint’s water was making persons sick, inhabitants took action. Here’s how the lead contamination disaster unfolded—and what we will learn from it.
even though Walters experienced plastic pipes inside her residence, lots of more mature homes have galvanized iron pipes of their walls, indicating that getting rid of any possibility of lead contamination would choose costly renovations.
applying samples taken by Walters in January 2015 and sections of the iron pipe that related Walters' residence on the guide services pipe, Edwards was in a position to pinpoint the contamination styles.
five-calendar year-extended disaster. “Corrosion Regulate is a crucial band-aid that permits us to decrease the hazard from your direct pipes for people,” stated Marc Edwards, an environmental engineer at Virginia Polytechnic Institute who served uncover the Flint water crisis.

Lab testing involves dissolving a part sample right into a liquid employing an acid as well as a lab-grade microwave inside a procedure referred to as “digestion.” after the sample is in liquid kind, we use a method referred to as “inductively coupled plasma mass spectrometry” (ICP-MS, or ICP Mass Spec) to measure chemical components like direct and cadmium in the sample.
