American Water Receives New Research Grant From Water Research Foundation
Grant to help fund research on cost-effective treatment technique for lowering TTHMs
American Water Works Co. Inc., the largest publicly traded U.S. water and wastewater utility company, announced it has received a grant from the Water Research Foundation to conduct research on a cost-effective treatment technique for lowering total trihalomethanes (TTHMs) in water distribution system storage tanks. The project is titled, “Localized Control of Disinfection Byproducts by Spray Aeration in Storage Tanks.”
TTHMs result from the addition of chlorine to drinking water and are regulated by the U.S. Environmental Protection Agency to not exceed 80 ppb. American Water will develop engineering guidance for the design, permitting, operation and maintenance of in-tank spray aeration systems for localized control of TTHMs. This treatment method will help water utilities meet the more stringent TTHM levels required under the upcoming EPA Stage 2 Disinfectants and Disinfection Byproducts Rule.
The project is valued at $300,000, with $150,000 funded by the Water Research Foundation.
“Our team brings together the perfect combination of innovation, expertise and experience to successfully develop a viable solution to reducing TTHMs levels,” said Mark LeChevallier, director of innovation and environmental stewardship at American Water. “With the upcoming Stage 2 rule, this research is extremely important for water utilities, which will help improve drinking water quality and provide additional public health protection.”
