New Radiation Testing Results for Black Berkey Filters

After much anticipation, we are happy to announce the release of new radiation testing results for the black berkey filters.  Below, please find a summary of the 3 sets of black berkey radiation tests.

Gross Alpha Reduction Testing Report <-- Link to 1st Set of Test Results

The Gravity Black Berkey Filter reduced the Gross Alpha concentration in the tap water by at least 98.7 %. The EPA limit for Gross Alpha is 15 pCi/L; the Gravity Black Berkey Filter meets the EPA requirements for drinking water.

Potential gross alpha contaminants/emitters in water:

Americium-241
Mendelevium-258
Neptunium-237
Plutonium-238 and -239
Polonium-210
Protactinium-231
Radium-226 and -228
Thorium-232
Uranium-235 and -238

Gross Beta Reduction Testing Report <-- Link to 2nd Set of Test Results

The Gravity Black Berkey Filter reduced the Gross Beta concentration in the tap water by at least 95.3 %. The EPA limit for Gross Beta is 15 pCi/L; the Gravity Black Berkey Filter meets the EPA requirements for drinking water.

Potential Gross Beta contaminants/emitters in water:

Actinium-227
Californium-251 and -252
Cesium-137
Cobalt-60
Iodine-129 and -131
Lead-210
Nickel-63
Promethium-145
Strontium-90
Technetium-99

Uranium Reduction Test Report <-- Link to 3rd Set of Test Results

The Gravity Black Berkey Filter reduced the Uranium concentration in the tap water by at least 97.0 %. The EPA limit for Uranium is 30 µg/L; the Gravity Black Berkey Filter meets the EPA requirements for drinking water.
