corrosivity

Still, the city was found to have violated standards for corrosivity, iron and manganese; those violations are based on the “aesthetic nature of the water,” according to state officials.

It was later found the state didn’t require Flint to properly treat water to reduce the corrosivity of the Flint river, which allowed lead to leach from pipes in households across the city of 100,000.

If there is no contact with electrodes, there are no corrosivity concerns,'' Mr. Keenan said.The technique could be used for tank wastes and for soil contaminated by tank leaks.
