Six years after petrol leaked into groundwater beneath a Napier service station, it has been decided to do nothing other than monitor it.
An unknown amount of petrol leaked from the Caltex service station in Hyderabad Rd in 2007, with two "plumes" found in groundwater and believed to be drifting toward residential properties.
Hawke's Bay Regional Council said station owner Chevron had given undertakings that the contamination would be dealt with, but this never happened and in 2012 it sought an enforcement order from the Environment Court.
Chevron said it preferred to deal with the contamination through "natural attenuation" - leaving it to break down naturally.
In affidavits obtained by The Dominion Post, council staff said they found that option unacceptable.
In response to a Local Government Official Information and Meetings Act request filed this month, the council said it had signed a confidential agreement with Chevron last September.
Under the agreement, the council withdrew its enforcement order. The parties agreed natural attenuation was best, with monitoring done twice yearly for two years and annually after that.
