This project will use woodchips from local ash trees damaged by the Emerald Ash Borer to filter water entering Purcell Park Pond from Sieberts Creek. Woodchip bioreactors are large pits in the ground that are filled with woodchips. Water is diverted through the system and the woodchips act as a media for bacteria to grow. The bacteria convert nitrate-nitrogen in the water to harmless nitrogen gas.
The project will be completed in partnership with the nonprofit Ridge to Reefs with funding provided by a National Fish and Wildlife Foundation grant.
The project is scheduled to be completed August 2019.
