City water study grows in scope, issues

“We cast a broad net and we caught more than we thought we would. We don’t want to do it and not do it right.”

The initial testing involved taking existing small sections of pipe from 10-12 locations from water plant to households/businesses.

The hope was that the testing would show the primary culprit to be corroded iron breaking away from aging pipes – some dating to the Great Depression – due to the caustic nature of the surface water and the new treatment protocol required.

That would have likely required little more than a tweaking of the chemical treatment protocol to address.

However, Kozan said the initial testing showed a more varied array of issues.

“We found there are multiple sources of iron and also sources for manganese,” Kozan said, noting both iron and manganese could be causing the discoloration and would also account for the various hues and intensity of the discoloration experienced throughout the distribution system.

“The discoloration could be performed by a variety of factors. We have so much variation in the data.”
