The Marshall Islands was the scene of fierce fighting between the US and Japan during the Second World War.
The US-based Golden West Humanitarian Foundation has just completed a survey of two of the country's atolls, and is now waiting for US State Department approval to begin the clean-up.
Golden West's program director Al Vosburgh says thousands of unexploded weapons, ammunition, and explosives still litter the country.
"Much of the contamination is bombs - up to 1,000 pound US bomb - which our survey found in Maloelap Atoll," he said.
"Obviously there's [also] a lot of kick-out munitions from the stocks that the Japanese had on hand for their shore-batteries and so forth and that go scattered around as the bombs hit.
"There's a fairly good selection of different types of ordinance and we're very interested in applying technologies to try and get that stuff cleared up."
The group, which has previously been involved in the clean-up of unexploded ordinance in Solomon Islands, is hoping to start work in July or August.
Mr Vosburgh says while there's not much construction on the atolls, the longer the ordinance remains, the greater the risk for locals.
"People do dig to create gardens and plant trees and that sort of thing, so that's a threat," he said.
"In addition to that we're always concerned that people might start fires...and that can cause a serious accident.
"We've seen that many times in South East Asia, where a surface fire will detonate a projectile or a munition that's just below the surface - so that's our main concern."
