We are proud to announce brand new black berkey testing results that show the Berkey removes Chloramines, Pharmaceuticals, BPA, and much more from your water. This highly anticipated round of testing was just completed, and can be found here.
Black Berkey Testing Highlights:
1) Bisphenol-A - Removed to greater than 99.9%. Many customers had the desire to pour their bottled water into their berkey, and had wondered if the system would remove this endocrine disruptor.
2) Chloramines - Removed to greater than 99.9%. With many water municipalities switching to chloramine disinfection instead of chlorine, there was a growing chorus of existing and potential Berkey customers wanting the answer to this question.
3) Pharmaceuticals - Removed to greater than 99.5%. This has been a hot button also. Many studies and articles have come out over the past 5 years showing how these pharmaceuticals are washing down our toilets and not being removed from our water supply by the local municipal filtration plant. The filters were tested for 17 different types of pharmaceuticals and they were all removed. No additional types of pharmaceuticals were available for testing at this lab, however the results should be similar for others.
4) Petroleum Contaminants - Removed to greater than 99.9%. With the unfortunately too common event of oil spills and petroleum contamination of waterways and water sources, this has been on the mind of customers for some time, especially since the gulf oil spill. The black berkeys would protect them from these contaminants.
5) Methylcycohexane-methane - Removed to greater than 99.9%. This was the contaminant that was involved in the March 2014 West Virginia oil spill.
6) Pesticides - Removed to greater than 99.9%. These had already been tested for before, however more pesticides were included in this round of testing.
7) Heavy Metals - Removed to greater than 99.1%. These had already been tested for before, however a couple more heavy metals were included in this round of testing.
8) Coliform and e-Coli - Removed to greater than 99.9%. These had already been tested for before and shown to be removed to over 99.9999%. This could be considered as confirmation testing.
Some additional testing notes:
NMCL set the limit of 99.9% or Log 3 reduction with the lab before testing began. Each Log level (percent) reduction costs significantly more for testing and is typically not needed. It boils down to a function of cost vs what levels they believed would be acceptable to customers & dealers. Log 3 (99.9%) reduction is significant and the testing costs are reasonable; that's why they settled on this level.
You will notice in the test results that most all of the contaminates measured after running through the Black Berkey element, show "less than" as the measured contaminate level left in the water. This means that the actual reduction levels are "greater than" 99.9% - exceeding the target reduction level tested for.
