[...] At Hanford’s new 200 West Pump and Treat plant, Hanford’s largest and most sophisticated plant for cleaning contaminated groundwater, the TEPCO visitors heard about the different systems to strip radioactive and organic chemical pollutants out of water pumped out of the ground.

Clean water then is injected back into the ground on two sides of the plume of contaminated water, helping to keep contamination from spreading.

“We’re using clean water to control the plume,” said Bill Barrett of CH2M Hill Plateau Remediation Co.

Fukushima might have a more daunting challenge. Hanford is in the desert, but Fukushima is in a mountainous area close to the ocean, [Masumi Ishikawa, general manager of the Nuclear Fuel Cycle Department for TEPCO] said.

Groundwater is close to the surface there, and before the 2011 disaster, it had a pumping program to make sure basements had no leaks. [...]
