Is Leaked, Radioactive Tritium in Mississippi River Drinking Water?

Editor’s Note:  IPN was informed by author John LaForge at Nukewatch that there is “new, breaking information about the tritium leak: The Nuclear Regulatory Commission has acknowledged (in its Draft Site Specific Environmental Impact Statement regarding the reactor operators application for a second license renewal)    that Northern States Power/Xcel Energy has admitted that its leaked tritium was detected in the Mississippi River following the massive accidental leak -- after publicly denying it several times.*

 This is a consequential admission, since the Mississippi is the drinking water source for 3.7 million in Mpls/St. Paul, their suburbs and another 20 million people downstream, since tritium persists in the environment for 123 years, since if consumed it crosses the placenta, since it cannot and is never removed from the water it contaminates.”

 * The recent, 829,000-gallon leak of radioactive tritium-contaminated wastewater, according to your Draft EIS, “likely” reached the Mississippi River. The Draft EIS states: “Tritium detections in wells near the Mississippi Riverbank (i.e., MW-29A, MW-33A, MW-37A, and MW-48A) in 2023 indicate tritium-impacted groundwater likely discharged to the river.” (NRC Draft EIS, Agency/Docket Numbers:  Docket No. 50-263; NRC-2023-0031; Docket ID NRC-2023-0031; Document Number: 2024-08746; https://www.nrc.gov/docs/ML2410/ML24102A276.pdf, on page “3-47”, lines 11 to 14, under “2022 Tritium Release to Groundwater”.)

 

Xcel Energy’s Monticello nuclear reactor on the Mississippi River has leaked some 829,000 gallons of wastewater contaminated with radioactive tritium into the groundwater on site, (1) more than double the 400,000 gallons Xcel first estimated.  The company has since replaced two leaking pipes, built an underground retaining wall, and is cleaning up after a second spill and its temporary reactor shutdown.  Yet, according to WCCO TV, for July 20, 2023, Xcel said a “small amount of leaked water may have reached the Mississippi River.” (2)

 On March 18, 2023, the Associated Press (AP) reported that a representative of the U.S. Nuclear Regulatory Commission (NRC) told them that the tritium-contaminated wastewater from the reactor couldn’t contaminate the water people drink.  The AP reporters quoted NRC spokesperson Victoria Mitlyng, writing, “Mitlyng said there is no pathway for the tritium to get into drinking water.”(3)

 In fact, there are two pathways for the tritium leak to get into drinking water.  First, the tritium in the 829,000 gallon leak is now in a groundwater plume that can move beyond Xcel’s Monticello site and reach private or public drinking water wells.

 Second, the groundwater plume, which moves toward the Mississippi, (4), will contaminate the river which supplies drinking water to one million-plus people in the Twin Cities and their suburbs and 38 million people downstream.

 Perhaps Mitlyng was misquoted, since the NRC and the AP have both reported that the plume of tritium-contaminated groundwater can move outside Xcel’s boundary.  In fact, both agencies have reported that Xcel’s stated purpose in hastily building an underground steel wall between the reactor and the Mississippi is to prevent the radioactive groundwater from entering the river. (5)

 The AP reported March 24, 2023 that Chris Clark, the president of Xcel Energy, acknowledged that the radioactive pollution can reach the Mississippi.  The AP reported:  “Even if the tritium reached the river, which Clark assured wouldn’t happen, it would dissipate within a few yards.” (6)  Clark’s assurance is either a mistake or a deliberate fib, because “dissipate” means to disappear or vanish.  However, tritium contamination in water lasts 123 years.

 Further there is no way to remove tritium from water once it’s contaminated- as the 1.5 million tons of tritiated wastewater being pumped into the Pacific Ocean from the three-reactor earthquake/ tsumani/ meltdown site at Fukushima proves.

 Why is Xcel’s tritium in the groundwater and the Great River such a threat to the people and animals that rely on it?  As the NRC says, “this is because tritium travels as a form of water through the soil faster than other radionuclides.”  (7)  The city of Minneapolis proudly declares, “Our water comes from the Mississippi River.  Roughly 21 billion gallons of water are pumped from the river each year, and 57 million gallons of drinking water delivered every day.” (8)

 We can’t say, “There’s nothing we can do.”

 Everyone can comment to the government regarding the risks posed by Monticello’s operations, when Xcel issues (this spring) its draft supplemental environmental impact statement (DSEIS) regarding the firm’s request to extend its license and run the 54-year-old reactor until 2050, when it will turn 80.

 The comment period will last four to six weeks and open after the DSEIS is released.  Check Nukewatch’s website to learn when the period has opened.  Use one of Nukewatch’s sample comments or your own.  Plan to make your voice heard in person once the NRC schedules a public hearing on the license extension.  Nukewatchinfo.org/Monticello
