What target did scientists NOT have when taking measurements for the city water supply?
pH Target - the pH was too low
Temperature Target - the water was too warm
Clarity Target - the water was too foggy
Flow Rate Target - the water moved too slowly
What can scientists add to the water that flows through old lead pipes to make it safe, and how does it work?
Orthophosphate - it creates a barrier (passivation layer) that stops heavy metals like lead from leaching into the water
Sodium Chloride (salt) - it kills bacteria and destroys metals like lead in the water
Dawn Dish Soap - destroys oil in the water & cleans the water
Filters on the street water lines- they stop heavy metals from reaching the homes
When did Flint switch back to the original water supply?
Summer 2014
Fall 2014
Spring 2016
Fall 2015
After switching back to the original water source, what problem still existed with the pipes due to a lack of proper water chemistry for more than a year?
The passivation layer was already gone, so lead was still leaching into the water
The water wasn't being treated even though they switched back to their original supplier
The new pipes had been installed in homes but people weren't using them
No one used the water at all so it just continued to sit in the old pipes, allowing bacteria to grow.
