A guest opinion from Tami Thatcher, who has written frequently in recent years about the Idaho National Laboratory and related nuclear industry issues. She said that she “was a nuclear safety analyst at INL for several years. . ..and then “graduated” in 2005. It’s a long story. Since 2005, I have provided contractor work for the INL, Keep Yellowstone Nuclear Free, and Environmental Defense Institute of tiny Troy Idaho where many of my articles are posted.”
I have been trying to piece together the history of radionuclide and chemical contamination of drinking water at the Idaho National Laboratory. US Geological Survey reports and data fill in much of the history of what was monitored since 1949.
State regulation of drinking water laws began to permeate INL in the late 1980s. INL contractors now perform the INL drinking water monitoring.
I visited the Idaho Department of Environmental Quality to see the data. What I discovered was that IDEQ does not collect or post online the radionuclide data for INL drinking water, only the chemical data.
In 1995, the IDEQ granted the DOE’s request to no longer provide radionuclide drinking water results.
Few people know that the radionuclide results for INL drinking water are not available at IDEQ or the site annual environmental monitoring reports.
The DOE’s own lax limits were 100 times more permissive than current federal drinking water limits. DOE and USGS reports that did disclose highlights of the contamination often emphasized that more permissive federal limits would soon be enacted. But they weren’t.
IDEQ ceased oversight of radionuclides in INL drinking water at a time when radionuclide levels remained at or near the federal limit. A legal loophole for non-community wells means the radionuclide contaminants are not regulated by the state.
A comprehensive review of chronically contaminated historical INL drinking water does not exist. The contamination has yet to be acknowledged in National Institute of Occupational Safety and Health’s (NIOSH) energy worker compensation dose reconstruction or epidemiology studies. The energy worker compensation law enacted in 2000 has paid out about $200 million in INL claims, but NIOSH does not disclose when or which facilities exposed the workers.
Brain tumors, leukemia and lymphatic cancers were found to be elevated in INL workers regardless of their recorded dose and whether or not they were radiation workers.
In the past, workers at INL’s Central Facilities Area were drinking up to five times the federal drinking water limit for tritium, 70 percent of the limit for iodine-129, and a host of other contaminants for decades. Drinking water wells at other INL facilities were also contaminated.
The full extent of Snake River Plain aquifer contamination from reactor operation, fuel tests, nuclear fuel reprocessing and waste burial remains obscured behind overly simplistic presentations that promote the idea that as long as current contamination levels don’t exceed federal limits, there’s no reason for concern.
There are serious radioactive omissions when it comes to describing current and historical drinking water contaminants at the Idaho National Laboratory.
Piecing together the full picture of all historical INL drinking water contaminants would require filling in those not monitored but later discovered to have been present.
Former workers (and their children) may wonder what they were exposed to. When weighing the benefits of future operations at INL, the public needs access to the full story of INL’s past and current contaminated drinking water.Share on Facebook
