Company will lead study focused on distribution system biostability
American Water Works Co. Inc. announced that it was awarded a research grant of $250,000 from the Water Research Foundation. American Water will directly receive $125,000 to pay for analytical costs, supplies, labor and other research costs, and approximately 20 utilities will provide in-kind contributions of $590,992. The total value of the project is $840,992.
The study, titled "An Operational Definition of Biostability in Drinking Water,” will examine practical indicators of distribution system biostability, including change in biodegradable organic matter, disinfectant demand and biodegradation of haloacetic acids, biofilm formation and corrosion rates, and biological consumption of ammonia, nitrate and phosphate. American Water, which will serve as the project lead, will perform the research in collaboration with Dr. Patrick Evans, vice president with CDM.
“We are pleased that the Water Research Foundation continues to recognize American Water as a leader in industry research,” said Dr. Mark LeChevallier, director of Environmental Stewardship and Innovation. “Our team of expert scientists and engineers, coupled with our large and diverse geographical footprint, provides an exceptional opportunity to study and develop best practices for the water industry.”
