(Updated) Japan Nuclear Radiation In Drinking Water In 14 US Cities And In Milk ABOVE EPA Limits


The EPA has finally released some of the radiation data it has been collecting:

  • Little Rock milk radiation – 3 times the EPA Maximum
  • Radiation in Philly Drinking Water 73% of federal drinking water standards.
  • Los Angeles milk radiation was above federal drinking water standards.
  • Radiation found in Phoenix milk was almost at the federal drinking water standard.
  • Radioactive Iodine in Boise Idaho rainwater was 130 times above Federal Drinking Water standards.
    • Radioactive Caesium was 13.66 times above federal limit for Caesium-134, 2 year half-life.
    • Radioactive Caesium was 12 times federal limit for Caesium-137, 30 year half-life.
  • Tennessee drinking water was detected with radiation slightly above 1/2 the federal maximum.
  • Radioactive Iodine has been detected in the drinking water across the entire US in the following states: California, Washington, Oregon, Idaho, Tennessee, Montana, Pennsylvania, Ohio, Michigan, New Jersey, and Alabama, as well as in Canada.
  • Cesium and Tellurium were found in Boise,  Las Vegas,  Nome and Dutch Harbor, Honolulu, Kauai and Oahu, Anaheim, Riverside, San Francisco, and San Bernardino,  Jacksonville and Orlando, Salt Lake City,  Guam, and Saipan.
  • Uranium-234, with a half-life of 245,500 years has been found in Hawaii, California, and Washington.


Radiation Detected In Drinking Water In 13 More US Cities, Cesium-137 In Vermont Milk


• Unusual Reading At Chatanooga Nuclear Plant

• Milk Contamination At EPA Maximum

• Highest Levels Yet In Boise Rainwater

Radiation from Japan has been detected in drinking water in 13 more American cities, and cesium-137 has been found in American milk—in Montpelier, Vermont—for the first time since the Japan nuclear disaster began, according to data released by the Environmental Protection Agency late Friday.

Milk samples from Phoenix and Los Angeles contained iodine-131 at levels roughly equal to the maximum contaminant level permitted by EPA, the data shows. The Phoenix sample contained 3.2 picoCuries per liter of iodine-131 […]

The cesium-137 found in milk in Vermont is the first cesium detected in milk since the Fukushima-Daichi nuclear accident occurred last month. The sample contained 1.9 picoCuries per liter of cesium-137, which falls under the same 3.0 standard.


A rainwater sample collected in Boise on March 27 contained 390 picocures per liter of iodine-131, plus 41 of cesium-134 and 36 of cesium-137. EPA released this result for the first time yesterday. Typically several days pass between sample collection and data release because of the time required to collect, transport and analyze the samples.


The sample was collected at the Tennessee Valley Authority’s Sequoyah nuclear plant. A Tennessee official told the Chatanooga Times last week that radiation from Japan had been detected at Sequoyah but is “1,000 to 10,000 times below any levels of concern.” The 1.6 picocures per liter reported by the EPA on Friday is slightly more than half the maximum contaminant level permitted in drinking water, but more uniquely, it is many times higher than all the other drinking water samples collected in the U.S.


Drinking Water

Radioactive Iodine-131 was found in drinking water samples from 13 cities. Those cities are listed below, with the amount of Iodine-131 in picocuries per liter. The EPA’s maximum contaminant level for Iodine-131 in drinking water is 3 picocuries per liter.

In the data released Friday, iodine-131 was found in rainwater samples from the following locations:

  • Salt Lake City, UT collected 3/17: 8.1
  • Boston, MA collected 3/22: 92
  • Montgomery, Alabama collected 3/30: 3.7
  • Boise, ID collected 3/27: 390

As reported above, the Boise sample also contained 42 pC/m3 of Cesium-134, and 36 of Cesium-137.


In the most recent data, iodine-131 was found in air filters in the following locations. In the case of air samples, the radiation is measured in picoCuries per cubic meter.
