Nutrients (ammonia and orthophosphate) are the significant issues impacting on water quality. Sediment is potentially a significant issue. Chloride and conductivity levels are also significantly elevated. Elevated chloride in freshwater can be an indicator of domestic sewage (or slurry) pollution
Agriculture and domestic wastewater treatments systems are the significant pressures

Carrigaholt requires a waste water treatment plant
