Spill kills fish, eels
Ammonia pollution has killed eels and small fish in two wetland ponds in Penrose.
A company is helping the Auckland Regional Council clean up after the spill was discovered last Tuesday.
The council was alerted by the Fire Service, which was called to investigate reports of an ammonia smell.
Council pollution response manager Nigel Clarke says the ammonia washed down stormwater pipes into the two small ponds in an industrial area of Great South Rd.
Officers were removing dead marine life from the ponds last Wednesday.
“The important message is whatever goes down the stormwater drain ends up in the local waterway and affects the life there,” Mr Clarke says.
He says the spill appears to have been contained in the two ponds.
There is no public access to the wetland area, which is surrounded by industrial sites.
The cause of the spill is being investigated but a local company has been told to start clean-up work.
That means flushing the stormwater pipes and hiring an environmental consultant to look at the effect on the ponds, Mr Clarke says.
