Do Berkey Filters Remove Arsenic?
What is Arsenic?
Arsenic is a natural mineral that is found in soil, rocks, air and water, but also can be found through industrial and agricultural means. Arsenic is toxic and its inorganic form, which is arsenic combined with sulfur, oxygen and chlorine, can cause arsenic poisoning over time.
Arsenic lasts a long time in the environment and previously was used for other purposes like lumber preservatives, pesticides and even poultry feed.
Health Risks of Arsenic in Drinking Water
While arsenic is natural, the health risks are for this contaminant are very real. Its inorganic form, which can be found in drinking water, is more harmful than the organic form and can change the functions of cells or replace them altogether.
Exposure to arsenic long-term increases your risk of cancer, diabetes, arsenic poisoning, cardiovascular disease, cognitive development issues for adolescents and even death. As a result, the EPA set a new standard for arsenic levels in drinking water in 2001 to 0.01 mg/l or 10 parts per billion (ppb), which is the standard we use today.
Is Arsenic in Your Drinking Water?
There are numerous ways arsenic can get into your drinking water. Industries release chemicals in the air, including arsenic, that eventually get into groundwater through precipitation (rain and snow). Industries can also release chemicals like arsenic into rivers, lakes and streams that can get into drinking water.
Weathering of rocks also releases arsenic into the soil, eventually making its way into groundwater, or it can enter directly into water sources like rivers lakes and streams that are used for drinking water.
In the United States, the west, midwest and northeast have high levels of arsenic in water, but arsenic is found in water sources in all 50 states, serving 108 million Americans. You can find out if arsenic and other contaminants are in your drinking water by looking up your local water utility online or visiting our Water Quality Search.
How To Remove Arsenic From Water
Reverse Osmosis is process where a high-pressure pump that forces water through a semi-permeable membrane. It removes heavy metals, bacteria and other contaminants, but also removes minerals and nutrients your body needs. This gives you pure water, but at the cost of keeping the good.
Ion Exchange is the method Berkey Filters uses to filter contaminants, heavy metals, viruses and other contaminants out of the water. A carbon filter attracts ions from less desirable contaminants to it and switches it out with one of another charge, bonding the old ions to the carbon filter. This process allows the good minerals to stay in the water and keeps out the contaminants you don’t want.
Berkey Filters is unique in that it has the ion exchange process, but the systems are designed to filter out more contaminants. This is done by integrating miniature pores in the carbon filters, allowing less harmful bacteria, heavy metals and viruses to get through and the gravity flow nature of the system itself, which slows the process down just enough to filter more out of the water.
Does the Berkey Remove Arsenic?
Based on test results from independent EPA-accredited labs across the country, Black Berkey filters reduce over 99.9% of arsenic from water. With that in mind, it is recommended to take this filtration process a step further by using the Berkey Fluoride water filter (PF-2™), which removes Arsenic III and V (pre-oxidized), alongside with Black Berkey filters.
Using both types of Berkey Filters at once is recommended because, over time, carbon elements that can remove fluoride and arsenic, like Black Berkey filters, can lose efficiency over time. Using Fluoride Filters allows the filters to work together so that the quality of the Black Berkey is consistent over time.
Big Berkey Water Filters are one of several Berkey systems that can use these both of these filters at once for the best water purification. Browse the Berkey Filters to find the ideal product for your family.
