Here are two articles, the first being from 2010 stating the radioactive isotope Strontium 90 was found in soils around Vermont Yankee nuclear power plant, the second from 2011 eleven stating Entergy “do(es) not know why the Governor would suggest Vermont Yankee is the source” of the recent Strontium 90 found in connecticut river fish.
Strontium 90 Now Found In Vt. Yankee Soil
May 21, 2010 BURLINGTON, Vt. — — Tests on soil samples taken at Vermont Yankee Nuclear Plant in Vernon now confirm the presence of a new – and more serious – form of radioactivity in the ground outside the reactor building.
Yankee spokesman Larry Smith released a statement late Friday afternoon confirming the presence of strontium 90 — a “hard to detect” isotope found 15 feet below ground in soils excavated during the search for a broken pipe leaking tritium last March.
According to the Smith statement: “The identification of strontium 90 is not unexpected given other plant-generated isotopes were previously identified in soil samples taken from the same location. Strontium 90 is a by-product of nuclear fission and atmospheric testing. Entergy Vermont Yankee is confident that the strontium 90 is limited to the soils in contact with or adjacent to the terminated leak. There is no risk to public health or safety.”
But nuclear engineer Arnie Gundersen, president of Fairwinds Associates of Burlington and a Yankee watchdog, told NewsChannel Five the discovery is no small matter.
“There are no worse isotopes than strontium-90,” he said. “It is the worst of the worst.”

Statement from Vermont Yankee, August 2, 2011
The following statement was released yesterday afternoon in response to Vermont Governor Peter Shumlin’s press release on strontium-90 detected in Connecticut River fish samples.
“We are aware that the Vermont Department of Health may have detected strontium-90 in some fish from the Connecticut River. There is absolutely no evidence to suggest that Vermont Yankee is the source for the strontium-90. We have 31 monitoring wells on site that are tested regularly. No groundwater sample from any well at Vermont Yankee has ever indicated the presence of strontium-90, or any other isotope other than tritium. We do not know why the Governor would suggest Vermont Yankee is the source, but there is no factual basis for that suggestion.”
