Tennessee Valley Authority officials have reported finding elevated levels of tritium in a groundwater sample taken from a monitoring well at the Sequoyah Nuclear Plant.

TVA spokesman Ray Golden and other officials said the elevated level of tritium, found in one of two new onsite monitoring wells, poses no threat to the health and safety of the public.

“The newly installed groundwater monitoring wells were placed in an area known to have contained tritium that was previously reported,” Sequoyah Plant Manager Paul Simmons said in a prepared statement. “The health and safety of the public are our primary concern, which is why providing additional monitoring capability to the plant’s groundwater wells is an important measure for protecting the community and the environment.”

Golden said there are a total of 16 groundwater monitoring wells on the Sequoyah site.

The highest level found in the sampling on Friday, Dec. 16, was about 23,000 picocuries per liter.

Golden said the Environmental Protection Agency’s drinking water standard is 20,000 picocuries per liter. The nuclear industries “voluntary reporting level” also is 20,000 picocuries per liter, he said.

A “curie” is the standard measure for the intensity of radioactivity contained in a sample; a picocurie is one trillionth of a curie.

Golden said the tritium has been detected in groundwater, which is not used for drinking water or irrigation purposes, and no potable water wells are downstream of where the tritium was found.

Ummm? What about the lake? Wouldn't eat the fish!

Don't trust what a TVA spokesperson says about TVA. If it was dangerous, the govenment is too broke to fix it anyway. They would rather blow smoke up our a.. and tell us it is safe and hope for the best.

I really wish people would get behind cleaning up the TN river. We went from one of the most poluted towns to one of the nicer outdoor towns. Unfortunately, one of our country's dirtiest rivers flows right through the middle of our town and it gets very little attention from everyone, wooks, libs, dems, repubs, right, left, black, white, asian. Why? Why don't we make more of an effort to clean up the river from knoxville to chattanooga, it can't be that hard?

TFP reported while all the flooding was going on that an upstream company can release so much mercury into the tn rive each year. Why? mercury are you kidding me?

Now this with tva, please people come together and lets get this river clean and have more than a pretty city with an ugly river running through.

So this sample was slightly more radioactive than two dozen bananas.

23,000 pCi is about 851 Bq. About 32 Bq to a banana in potassium-40. About 26.5 bananas would exhibit about as much radioactivity as the described sample.

A human naturally produces, in our own bodies, as a direct result of the digestion of naturally occurring potassium compounds, about 5,000 Bq's worth of radioactivity in our lifetime. The described sample would be less than 20% of what we make inside ourselves, naturally.

Before we try to scare everybody with claims of "don't eat the fish" and "clean up the river", maybe we should try to find out what these scientists said. They told us, straight up, "23,000 picoCuries per liter".

We probably walked past more radioactivity in the produce section of the grocery store.

Here we are with some of the best natural hydro power available in the world and one of the few efficient energy storage systems in the world and still we need toxic towers?? I don't think so. When will mankind learn that you don't poop where you sleep. Even a puppy knows this.

OTS - How many more dams do you think we need and where would you put them? Every river in the TVA watershed that can handle it has power producing dams.

As far as energy storage systems, a few years ago, a company attempted to build more pumped storage generation plants like Raccoon Mountain in the mountains surrounding Chattanooga until the public outcry ran them out of the area and they built them in another location.

Nuclear power is far cleaner than the fossil fuel plants that TVA is shutting down. Each nuclear plant produces more than 2 megawatts of electricity. Take 'em away and you'll be "watching TV by candle light." LOL

I talked to two TVA guys years ago. They both lied to me. Kinda ruined any respect I had for TVA.
