"Radioactive Water Leak at Minnesota Nuclear Plant Being Cleaned Up"

Officials are monitoring the clean-up of a leak of 400,000 gallons (1.5m litres) of radioactive water from a local nuclear power plant in Minnesota. The leak was first discovered in late November, but state officials did not notify the public until Thursday. The water contains tritium, a common by-product of nuclear plant operations. Roughly one-quarter of the spilled tritium has been recovered so far, and Xcel has said it may build above-ground storage tanks to store the contaminated water.
