Wildlife hospital inundated
A wildlife hospital is inundated with ducks covered in oil since a Kaiapoi factory fire spilled a toxic product into nearby rivers.
Fifteen ducks have been transferred to the South Island Wildlife Hospital in Christchurch since the blaze destroyed the factory, but three subsequently died.
Veterinarian Pauline Howard said the 12 remaining ducks were doing well but would need intensive care in the coming weeks to wash and waterproof their feathers.
Called wet feather, the condition occurs when a duck’s feathers become waterlogged due to contamination with oil, detergents, lice or sooty black mould, causing them to lose their ability to repel water.
Howard said the ducks were unable to control their body temperature while they were covered in oil and that had caused two deaths, with one arriving too hot and another arriving too cold to save.
Sutton Tool NZ, Australasia’s largest drill bit manufacturer, suffered catastrophic damage in its main manufacturing facility after fire engulfed the building last week.
The blaze was so fierce a nearby resident described feeling a heat blast on his face after one explosion, and people from up to 40 houses had to be evacuated to a nearby school because of the risk of toxic fumes. The fire also caused a product called quenching fluid to leak via stormwater drains into the Kaiapoi and Waimakariri rivers.
Designed to rapidly control the cooling of steel or other materials as part of the hardening process, the fluid produced oil slicks on the surface of the rivers.
Environment Canterbury onscene commander Emma Parr said 18 New Zealand scaup – or black teal ducks – affected by oil had been captured and transported since the spill.
ECan advises anyone who sees oiled birds not to attempt to capture or clean them but to ring the incident response team with details of the location.
‘‘It can be distressing to see birds in this way, but the best way you can help them is by letting us know where they are.’’
Parr said a final flush of the stormwater link between the site of the fire and the Cam/ Ruataniwha River was carried out. The flush did discharge some oil, which booms collected and sucker trucks removed.
Brooklands lagoon and some less accessible areas are being surveyed for oil, both on water and by land, she said.
‘‘To date, we’ve recovered approximately 2400 litres of oil from the water using sucker trucks and another approximately 250 litres of oil using sorbent materials.’’
Oil at the site of the fire had been contained, she said.
‘‘We will be monitoring for any further oil over the coming weeks.’’
