The cover-up of workers’ illnesss in radioactively polluted clean-up of Kingston coal ash spill

A Legacy of Contamination, How the Kingston coal ash spill unearthed a nuclear nightmare, Grist By Austyn Gaffney on Dec 15, 2020  This story was published in partnership with the Daily Yonder.

………………………………….The apparent mixing of fossil fuel and nuclear waste streams underscores the long relationship between the Kingston and Oak Ridge facilities………… .

……….In 2017, a former chemist named Dan Nichols stumbled upon a news story that revealed the existence of the additional health problems TVA feared. High levels of uranium had been measured in the urine of a former cleanup worker named Craig Wilkinson. Like Thacker, Wilkinson had worked the night shift. After dredges piped the coal ash back onshore, Wilkinson used heavy equipment to scoop, flip, and dry the wet ash along the Ball Field.

Although Wilkinson worked at the Kingston site for less than a year, he quickly developed health issues, including chronic sinus infections and breathing problems that eventually led to a double-lung transplant. Frustrated by his sudden decline in health, Wilkinson shelled out over $1,000 for a toxicology test because he wanted to know what occupational hazards might be lingering in his body.

After reading Wilkinson’s story, Nichols sat stunned. Though he was not associated with the spill, he’d been unable to shake his obsession with the Kingston disaster. Nichols had worked as a Memphis-based field chemist for a wastewater technology company, and he was used to studying lab reports on industrial water supplies and samples. For years he’d been trying to solve a mystery that no one else seemed to be aware of: why Kingston regulators deleted and then altered a state-sanctioned report showing extremely high levels of radiation at the cleanup site.

Roughly a month after the spill, Nichols read a Duke University press release stating that ash samples collected at Kingston by a team led by Vengosh, the geochemist, showed radium levels well above those typically found in coal ash. Nichols knew that the state environmental regulator, the Tennessee Department for Environment and Conservation, or TDEC, was also testing soil and ash samples at the site. After seeing Vengosh’s high radium readings, he wondered if TDEC’s report would also show high levels of either radium or uranium. (Radium is a decay element of uranium.) Later that spring, Nichols visited TDEC’s website and discovered the test results.

“I opened it up and went to uranium, and it was just off the charts,” Nichols recalled. In a 2020 affidavit, Nichols reported that these levels were “extremely high so as to be alarming.” At least 27 soil and ash samples were collected from at least 20 different sites surrounding Kingston beginning January 6, 2009. The levels ranged from 84 parts per million (ppm) to 2,000 ppm. The average level was over 500 ppm, as much as 50 times the typical uranium content found in coal ash.

The next morning, when Nichols slumped back into his computer chair and refreshed TDEC’s website, he saw that the report had been changed. The high uranium readings had plummeted. Now the average uranium levels in the ash were 2.88 ppm, a tenth of the typical uranium content found in coal ash and illogically, below levels naturally occurring in soil. Luckily, Nichols had downloaded the unaltered report the night before.

A month later, Nichols sent the two lab reports to one of the attorneys representing Tennessee residents affected by the spill in a lawsuit they’d brought against TVA. According to Nichols, the lawyers weren’t interested. Nevertheless, Nichols was determined to find more proof of the unusually high levels of on-site radiation. In between cutting hay and spraying weeds on his family farm, he spent years poring over information online about TVA, coal ash, and uranium before he stumbled across Wilkinson’s story.

Back in 2014, Wilkinson’s urine tested for unusually high levels of both mercury and uranium. The mercury is more easily explained: The most common cause of mercury contamination, according to the EPA, is coal-fired power plant emissions, which account for 44 percent of all man-made mercury pollution. The 2008 spill released 29 times the mercury reported at the Kingston site for the entire decade before it, and TVA documents show high levels of additional legacy mercury were present in the Clinch River and could have migrated into the Emory. Today, Wilkinson has symptoms attributable to methylmercury poisoning including blurry vision, fatigue, a hearing impairment, memory loss, and loss of coordination that caused him to fall out of the machines he operated until retiring on disability in 2015.

But most shocking to Nichols was the high level of uranium in Wilkinson’s body — it was 10 times the U.S. average, and identical to the median levels that one study found in workers exposed to the substance. Prolonged occupational exposure to uranium is strongly linked to chronic kidney disease, which Wilkinson suffers from. Because Wilkinson’s toxicology results were taken four years after he left Kingston, they likely show lower uranium levels than what he and other cleanup workers initially had.

Wilkinson’s results left no doubt in Nichols’ mind that the original uranium readings he’d saved were significant. A reporter for the Knoxville News-Sentinel, Jamie Satterfield, contacted him after the report he saved showed up in court proceedings. Satterfield published a story about the altered uranium readings in May of this year.

In response to her story, TDEC told the News-Sentinel that its updated uranium readings, which plummeted by 98 percent, were due to a change in the sampling method used for the tests. (Satterfield also reported that radium levels had been lowered between the initial TDEC report Nichols downloaded and the updated one; the department attributed this to a “data entry error.”) In an email response to Grist and the Daily Yonder, a TDEC spokesperson elaborated that the sampling lab, which was neither staffed nor supervised by TDEC, “discovered there were interferences in the analysis of soil and ash samples for uranium” and subsequently changed the method of analysis from one EPA-approved protocol to another. The new results were then published without public notice of the alteration.

“Changing lab reports is a very serious thing,” Nichols said. “But I can assure you data entry errors don’t cause a man to test for unusually high levels of uranium. That’s [TDEC’s] big problem.”

Unbeknownst to Nichols, Russell Johnson, the district attorney with jurisdiction over Roane County, where Kingston is located, had informed TDEC’s commissioner in 2017 that he was beginning a criminal probe into the Kingston cleanup. “I am deeply concerned with the apparent intentional conduct of the cleanup contractors and their supervisors, actions that took place in Roane County, conduct that may indeed have caused serious bodily injury or possibly even death to a number of people,” Johnson wrote in a letter to TDEC.

In concert with the Tennessee Bureau of Investigation, Johnson began investigating whether TVA or its contractors “suppressed information” as part of the coverup alleged in the 2013 worker lawsuit against Jacobs. They now have Nichols’ evidence as well. But despite this ongoing investigation, it’s unclear if workers will ever learn for certain whether or not they were exposed to dangerous substances besides the coal ash itself. (Bob Edwards, an assistant district attorney working under Johnson, told Grist and the Daily Yonder that the district attorney’s office could not comment on a pending investigation.)………………….https://grist.org/justice/tva-kingston-coal-ash-spill-nuclear/
