City water study grows in scope, issues

Published: Thursday, July 11, 2013 at 10:06 AM.

Kozan said the manganese is not coming from water entering the plant. Whether the source is rainfall or from the distribution system – the city is nearing phase two of a three-phased project to replace some 20 miles of aged pipe – or another source is unknown.

“We were a little surprised to see as much manganese,” Kozan said. “(Identifying the source) is a very complicated problem to solve.”

City manager Jim Anderson said manganese had also been a significant problem with city officials in Dalton, GA, the site of a water plant and microfiltration that in the entire country most closely mirrors the Port St. Joe plant and system.

Kozan said he was unaware of that and asked Anderson for additional information.

Kozan said the study was also somewhat hamstrung by the lack of historical data.

The plans for the pilot study have now changed, Kozan added. The company will now likely harvest just one existing pipe section to send to Virginia Tech. Beyond that, the university will use “metal blanks” or unused pipe as comparison for a variety of chemical tests.

Kozan said he was looking to take a section of two-inch galvanized iron pipe from the area of Avenue A-Avenue B.
