Pilot studies on organic carbon levels approved
Fayette County commissioners June 10 unanimously approved funding for two pilot study treatment techniques designed to address the levels of total organic carbon in the South Fayette Water Treatment Plant. Though the county is currently in regulatory compliance, the tests will help the county decide on a course of action if the need arises in the future.
The county is now in compliance with its treatment technique for total organic carbon, according to the water system’s annual water quality report. That notwithstanding, and though the higher organic carbon levels at the Lake Horton Reservoir affects neither the taste nor clarity of drinking water, commissioners agreed to a cost of $49,950 to conduct the two pilot studies to determine which treatment technique would be more suitable for Fayette County’s use.
One of the techniques, MIEX DOC, will involve the use of a magnetized ion exchange resin to remove dissolved organic carbon from drinking water supplies. The technique also has the ability to remove large portions of sulfate, nitrate and chromate ions, according to information provided by water system Director Tony Parrott. The total cost for the pilot study of this technique is $14,800.
The other technique, ACTIFLO CARB provides a new, high performance polishing system using micro-sand that will remove taste, odor and coloration, along with organic and inorganic matter, officials said. The total cost for the pilot study of this technique is $35,150.
