Asbestos clean up in park
BURIED ASBESTOS has been discovered in a Grey Lynn park, sparking a threeweek clean-up.
Work begins on Monday to remove the asbestos-based roofing material found in Arch Hill Reserve during a walkway upgrade in November.
Auckland City Council urban soils review project manager Marcus Herrmann says it’s thought the material was dumped illegally some decades ago.
“We don’t have any evidence of when it was dumped but we understand that the type of roofing was used in the 50s and 60s,” he says.
“We’re dealing with a historical illegal dumping issue and the focus is on cleaning it up rather than trying to assign liability.”
The contamination was discovered at the western end of the park on a steep slope below the Grey Lynn library.
Once found, the area was fenced off and covered with a secure barrier matting.
The matting has been checked twice daily and air monitoring has shown no sign the fibres have escaped.
Staff from the library and nearby St Joseph’s School were informed but were not at any risk, the council says.
Clean-up was delayed while engineers looked for a way to remove the 30 cubic metres of contaminated soil without causing a slip on the steep slope.
A specialised retaining barrier will be anchored over the upper slope during the work, which will be postponed in heavy rain or strong wind.
Once the decontamination work has been done, the slope will be landscaped with native plants.
During the work walkways will be closed to the public from 9am to 3pm on weekdays and 8am to 5pm on Saturdays.
The work will not affect mountain bike trails which are planned for a different section of the five-hectare park.
