The city of Newport, Oregon used to control manganese levels in its water by prechlorinating. The chlorine would oxidize the manganese, and it wouldn't discolor the water. Because of high levels of disinfection byproducts, the city has discontinued this practice, and residents have been getting brown water.
The city can control the manganese levels by adding permanganate to the water, which is a strong oxidizer. This will only cost an extra six percent to the people buying water in the city.
How much does anyone want to bet the permanganate will create oxidation byproducts of its own?
