Excerpt:

All of the drain lines containing radium-226 paint waste at Alameda Point have either been removed, cleaned, or are scheduled to be cleaned or removed, except for one: The Industrial Waste Line in the hangar area where aircraft dials were painted. This drain line was installed in the mid-1970s after passage of the Clean Water Act prohibited sending industrial waste into public waterways. It sent wastewater to a treatment facility, and is now lying dormant, broken in places, and no longer in use. The big question is what to do about it – leave it alone and create a special radiological license, a special exemption, or dig it up?
