Today, the Niagara Falls Water Board responded to the Department of Environmental Conservation's request for documents relating to the wastewater discharge in the Niagara River back in July.
Here's what you need to know:
The Board admitted the technology at the Water Resource Recovery Facility "is no longer the most appropriate treatment technology for the WRRF's current waste stream."
The NFWB determined the black discharge happened during the de-watering of a sedimentation basin. The pump ran longer than expected as a result of an employee misunderstanding.
To prevent a similar event, the Board says it will "implement new procedures for emptying or de-watering any basin or tank in the future."
NFWB proposed the WRRF's sludge removal process be improved by "raising/modifying" pumps to reduce the chance of discharge contaminating water.
The investigation is ongoing.
