Island Bay residents are being asked to help find the source of recurring orange discharge, thought to be from paint poured down a drain.
Residents have seen the discharge coming from the stormwater outfall at the end of the concrete pier on Island Bay Beach several times in the past year, Greater Wellington Regional Council environmental regulation department manager Alistair Cross said.
Mr Cross said it was hard to trace the source of the contamination due to the size of the stormwater catchment for the outlet, which flows in to the Taputeranga Marine Reserve.
"To trace the contamination back would require us to follow a maze of connecting drains in the vain hope that we reach the contamination source before it ceases. In this case it appears that someone has poured paint into the system and I doubt that we would ever be able to locate the source," Mr Cross said.
"We have made a significant effort to make sure people understand that paints, solvents, chemicals and wash water should never go down private stormwater drains or roadside gutters. These drains often flow directly into streams and the sea with little or no treatment."
"It is disappointing to see this sort of thing still happening, and we appreciate the support we get from residents who help pass the message on, stay vigilant and keep us informed," Mr Cross said.
If you see any waste going into the gutter, call the Greater Wellington Regional Council's 24-hour Environment Hotline on 0800 496 734.
