TEPCO suspects worker error in wastewater problem

The operator of the crippled Fukushima Daiichi nuclear plant says a mix-up over switches may have sent 200 tons of highly contaminated water into the wrong building.
Tokyo Electric Power Company says workers may have turned on water pumps instead of air conditioners. The utility found the problem on Friday.
TEPCO says it is investigating why 4 pumps that were supposed to be offline sent the water into the basement of a building instead of temporary storage houses.
It says the switchboard has similar switches for pumps and air conditioners, with no indication to show their functions except for numbers.
The utility says it is investigating whether the problem was caused by worker error or a deliberate act.
Officials say they marked the switches accurately but are working out stricter measures to prevent technical errors.
