Here is a good article written by Mari Yamaguchi that explains the state of contaminated water at the Fukushima Daiichi plant. Experts say that the ice wall that was built to keep groundwater from coming into the power plant and becoming contaminated with radioactivity is only half effective. A conventional drainage system also collects water from wells dug around the plant and pumps it out before it becomes contaminated. This water is stored in about 1,000 storage tanks near the facility. Read more about the construction, operation and maintenance costs that are coming out of the taxpayer’s pocket.
Greenpeace radiation specialist Jan Vande Putte visits towns near the Fukushima No. 1 site and measures radiation levels in the homes, streets, playgrounds and nearby forests. The government has lifted evacuation zone orders in certain areas like Iitate and plans on lifting evacuation orders in towns like Namie that are still highly contaminated. Putte looks at this issue from a human rights perspective, as residents of these towns are being threatened by the government to move back to contaminated areas because of the termination of their monthly compensation that they use to pay for housing where they have relocated.
