Title	Unplanned Contamination Event
Event Description	Facility suffered a sewer blockage in the Waste Building on the morning of 09/02/2004. Soil waste removed to discover cause of blockage. It was immediately determined that the line was not connected to the sanitary sewer. The line has been in place for 12 years for the disposal of H-3 and C-14 waste. An estimated total of 100 millicuries of these radioactive materials have been disposed during the last 12 years. Maximum soil contamination discovered was measured at 0.1 millirem per hour. No workers or equipment were contaminated. The University immediately let a contract for cleanup of the contaminated soil and repair of the sewer line. The area was placed behind barrier tape and covered with plastic to prevent blowing or erosion. Initially, the soil was removed and barreled by a licensed Texas decontamination firm. A second break in the line was discovered near the building that may require soil removal by covered roll-off container.
