NEPA collaborated with the Water Resources Authority and the National Irrigation Commission to determine the exact cause of the fish kill. Collective site visits and sampling of the river found that the fish kill originated within the Lower Black River Morass, downstream of Lacovia and south of Holland Estate. There are no known facilities within the Lower Black River Morass which discharge wastewater into the river or its tributaries.

Pollution incidents

The agency is reviewing its response strategy and will shortly implement a plan that will involve community monitors to better respond to pollution incidents in the future. NEPA will also continue to work closely with related public entities to increase its monitoring of the Black River and its tributaries.
