What happens to used sandbags? Depends where you live

While the City of Ottawa and dozens of other municipalities along the Ottawa River remained in a state of emergency Thursday, officials beganaddressing thequestion of how to dispose of the approximately four million sandbags used in the battle to keep homes dry.

Anthony Di Monte, Ottawa'sgeneral manager of emergency and protective services, estimates this city alone will be left with1.5 millionused sandbags, each of which poses a health risk.

"It's not toxicbut it is contaminatedbecause the septic systems have failed and now the sandbags are soaked with water with the contamination from the septic system," Di Monte said."There's E. coli and all those other issues, so we have to dispose of them appropriately."

Landfill off limits for Ottawa...

Di Monte stressed that residents should not move sandbags until instructed by the city, especially withheavy rain in the forecast thatcould cause water levels to peak again on Sunday.

"Our city remains in a state of emergency to provide the necessary aid to the affected areas," Di Monte said. "We are asking residents to keep their sandbag walls up."

Simply dumping the used sand into the city's landfill isn't in the cards, according to Kevin Wylie, the city's general manager of public works, who said Wednesday staff have put together a task force to consideroptions.

"We have quite a robust recovery task force now. It includesour partners from public health, and we are looking at very innovative ways of reusing that sand," Wylie said. "The last thing we want to do is landfill it."

...but not for Clarence-Rockland

Downstream in the municipality of Clarence-Rockland they're takingthe opposite approach,using the contaminated content of some270,000 sandbagsto meet an existing need.

The municipality plans to use the sand as a cover layer over freshly dumped garbage at its landfill, something it's required to do anyway under provincial regulations to prevent seepage and keep wildlife away.

As of Thursday, Clarence-Rocklandwas developing a larger cleanup plan, with details to be announced shortly.

Gatineauto use sand on roads

Even though officials with the City of Gatineau agree that sand from the sandbags contains contaminants, they nevertheless plan to reuse the sand for roadwork, and to spread on city streetsnext winter.

Such uses are permitted in Quebec,according to the province's Ministry of Public Security, which publishes guidelines on what to do with sand from used sandbags.
