New ingredient to be added to Columbus tap water

Press Release

COLUMBUS, GA - Columbus Water Works will begin on Monday, June 21, 2010, to introduce a new corrosion control additive to our drinking water.

This change will be made gradually over a fifteen to eighteen month period by adding increasing amounts of phosphate while reducing the pH of the water.

Cliff Arnett, Senior Vice President Columbus Water Works explains "Columbus Water Works has always provided effective corrosion control but will be making a fundamental change to the method over the next fifteen to eighteen months.

The taste, appearance, and quality of the water will not change for those consuming the water. The only change will be the corrosion control methodology".

"Historically, lime (calcium oxide) has been added to the water to increase the pH to 8.9 which renders the water non corrosive. The new methodology involves the addition of phosphate while reducing pH to 7.5 in order to achieve corrosion control among other benefits", Cliff Arnett explained.

The pH scale is used to express the balance between materials in water, which on one hand tend to make it acid, and on the other hand tend to make it alkaline.

The acidity or alkalinity of water is measured on a scale of 1 to 14 called the pH scale. Values below 7 indicate acidity and values above 7 indicate alkalinity.

Phosphate chemicals are recognized substances which can be safely added to potable water to produce a significant improvement in many water quality parameters.

There are many benefits to adding phosphates to our drinking water, however; Columbus Water Works wants to assure you that phosphates have a long history of successful application in drinking water treatment, providing both primary and secondary benefits. Phosphates are widely used to meet regulatory rules and produce quality drinking water our customers expect and deserve.
