The Taranaki Regional Council says an independent report into Marfell Park has verified there is no need for residents to worry about contamination or environmental risks.
The council ordered an independent investigation into soil quality at the former landfill in New Plymouth after two drums containing toxic chemicals were found by contractors laying stormwater pipes in May this year.
The investigation, conducted by Pattle Delamore Partners, analysed soil samples from 85 locations around the park for dioxins, pesticides, herbicides, heavy metals and other contaminants.
The council's environment quality director, Gary Bedford, says all samples were well below the appropriate safety guidelines and were lower than other landfills that have been investigated.
Mr Bedford says concerns about safety should now be dispelled. He says the report did recommend additional soil cover where the drums were originally excavated and this has been done.
