Today I went out on the Watercare Harbour Clean-Up Trust boat. We set off at a leisurely pace from downtown auckland in a rugged little boat (they are getting a new one next month) and headed under the Harbour Bridge out to the entrance to the Whau river. We kayaked over to Pollen Island and in just a few hours filled 9 bags with plastic before heading back. Amongst the expected bottles, bags and wrappers we also found:
One of those really old coke bottles with the removable black base
Lots of balls and kids toys
x4 Syringes (Needles)
x2 LPG Canisters
These guys have been doing this for 10 years and made a huge difference to the health of the Harbour. There is still a lot of historical waste to remove but we desperately need better source control. Interestingly they would prefer plastic to break down slower so it is easier to collect and remove. I left a lot of toxic little bits in the sand and rushes. I am looking forward to heading out again with Skipper Ben and hopefully the organiser Hayden Smith who are both awesome guys.
After being trained to do pest control for Auckland Council. I have joined the Selwyn Bush roster (only 14 traps sites). The people at Conservation Volunteers seem to do a lot to help but I should help them make a web app as the data entry is pretty painful.
I am used to seeing icky contaminated run off like this. From here. UPDATE: I think this is bubbling up from landfill (we have over 200 different sites around Auckland City). I have asked Auckland Council about it.
But this is just weird, it dries hard. Like the mud is covered in milky ice. I found it here.
I didn’t really get how zinc from galvanised roofs could be poisoning the estuary until I made this map. I found a presentation by Marcus Cameron which suggests that sites the source (the head of the estuary) are trending up (more zinc). At the same stormwater conference Judy Anne Ansen showed a pie chart on Industrial (Mt Wellington) zinc sources with about 80% attributed to roofs.
