Officials: Columbia River Is Safe
Officials: Columbia River Is Safe
RICHLAND, Wash. (AP) - High-level nuclear waste buried at the Hanford
nuclear reservation is apparently not an immediate threat to the
Columbia River, less than four miles away, the Energy Department said
Thursday.
Agency officials said groundwater contaminated by radioactive tritium
appeared to be confined to an area on the edge of the site where the
material was buried decades ago.
Officials could not say how extensive the contamination was, how fast
it might be moving or when it might reach the river.
``We'd like some answers soon,'' said Mike Goldstein, an official
with the U.S. Environmental Protection Agency.
The groundwater contamination was measured this year at 400 times
higher than the federal safety standard.
Tritium is a radioactive isotope of hydrogen that poses a cancer risk
when ingested. It was produced at Hanford to boost the explosive
power in nuclear warheads.
Last January, the high level of tritium was detected in a Hanford
monitoring well near the waste site. The well is also in the path of
a huge tritium plume stretching from the central part of the 560-
square-mile reservation to the river.
The source of the tritium remains unknown, but it is believed to be
coming from five large corrugated metal pipes and 50 bottomless
buried 3 1/2 miles from the river in south-central Washington. The
waste also includes 11 to 22 pounds of plutonium.
Hanford does not expect to begin cleaning up the site until at least
2010.
