❝Uranium, the stuff of nuclear fuel for power plants and atom bombs, increasingly is showing in drinking water systems in major farming regions of the U.S. West — a naturally occurring but unexpected byproduct of irrigation, of drought, and of the overpumping of natural underground water reserves.
An Associated Press investigation in California’s central farm valleys — along with the U.S. Central Plains, among the areas most affected — found authorities are doing little to inform the public at large of the growing risk.
❝That includes the one out of four families on private wells in this farm valley who, unknowingly, are drinking dangerous amounts of uranium, researchers determined this year and last. Government authorities say long-term exposure to uranium can damage kidneys and raise cancer risks, and scientists say it can have other harmful effects.
In this swath of farmland, roughly 250 miles long and encompassing major cities, up to one in 10 public water systems have raw drinking water with uranium levels that exceed federal and state safety standards, the U.S. Geological Survey has found.
More broadly, nearly 2 million people in California’s Central Valley and in the U.S. Midwest live within a half-mile of groundwater containing uranium over the safety standards…
❝Everything from state agencies to tiny rural schools are scrambling to deal with hundreds of tainted public wells — more regulated than private wells under safe-drinking-water laws.
That includes water wells at the Westport Elementary School, where 450 children from rural families study outside the Central California farm hub of Modesto.
At Westport’s playground, schoolchildren take a break from tether ball to sip from fountains marked with Spanish and English placards: “SAFE TO DRINK.”
The school, which draws on its own wells for its drinking fountains, sinks and cafeteria, is one of about 10 water systems in the farm region that have installed uranium removal facilities in recent years. Prices range from $65,000 for the smallest system to the millions of dollars…
❝The uranium gleaned from the school’s well water and other Central California water systems is handled like the nuclear material it is — taken away by workers in masks, gloves and other protective garments…
It is then processed into nuclear fuel for power plants…
❝Meanwhile, the city of Modesto, with a half-million residents, recently spent more than $500,000 to start blending water from one contaminated well to dilute the uranium to safe levels. The city has retired a half-dozen other wells with excess levels of uranium…
❝In California, as in the Rockies, mountain snowmelt washes uranium-laden sediment to the flatlands, where groundwater is used to irrigate crops.
Irrigation allows year-round farming, and the irrigated plants naturally create a weak acid that is leeching more and more uranium from sediment, said Miranda Fram and Bryant Jurgens, a fellow researcher at the federal agency’s office in California’s capital.
Groundwater pumping pulls the contaminated water down into the earth, where it is tapped by wells that supply drinking water.
California is now experiencing its driest four-year span on record, and farmers and other users are pumping groundwater at the highest rates ever, helping to pull yet more uranium into areas of aquifers tapped by water wells…
❝“This has been a decades-long process that has occurred,” Jurgens said.
And even if authorities were to intervene to somehow curb uranium contamination — and no such effort is under way — “we expect that it’s going to take many decades to reverse this,” Jurgens said.
RTFA. Please. Especially if you live in or around the farming valleys of California.
It is clear that the problem ain’t going away on its own. It is only going to get worse. State authorities are so drawn to other problems of the drought they’re not dealing with this much at all. And no one’s certain what they can do about it – anyway.
