About Big Berkey Water Filters

Top 3 ways a Berkey Water Filter will benefit your life

Drink To Your Health. Berkey water filter systems are far superior to other filtration systems because they remove harmful pathogenic bacteria, cysts, parasites, and unhealthy chemical contaminants such as Chlorine to levels higher than 99.99%, while at the same time leaving in the essential minerals your body needs.
Did you know that over 60% of US municipal water is fluoridated? Berkey water filter systems also distinguish themselves from many other filtration systems by having the capabilities to significantly reduce fluoride and arsenic via the "PF" line of filters.

Affordability. Each durable Black Berkey Water filter will last up to 3000 gallons (6000 gallons per set of 2). This is much longer than the majority of water filter solutions on the market.
At 10 gallons per week, this equates to more than 11.5 years of healthy clean drinking water!
Including fluoride and arsenic reduction, 1 gallon of Berkey water costs just 7 cents!.
Stop and think how much money you could save by the simple reduction in bottled water purchases by regularly using water filtered by your Berkey water filter.

Versatility. Berkey Water Filter systems are capable of purifying both treated water (municipal/city water) and untreated raw water from such sources as remote lakes, streams, stagnant ponds, and water supplies in foreign countries.
The micro-pores within the self-sterilizing and re-cleanable Black Berkey water filter purification elements are so small that pathogenic bacteria are simply not able to pass through them.
Due to the fact that the Berkey water filters do not require electricity and are portable, they become a lifesaver during times of flooding, loss of electricity, and other life threatening emergencies.

    • 'Rock Moisture' Could Protect Forests from Drought

      Water trapped within layers of rock may offer forest trees a lifeline during extended periods of drought, a new study has found. In a report that was recently published in the scientific journal PNAS, a team of researchers examined water stored within a layer of bedrock that is typically found beneath layers of soil in mountainous areas. Sandwiched between soils above and groundwater below, it is a zone that is very often overlooked by hydrologists. But on closer inspection, the research team found that water trapped within the pores and fractures of this rock layer could play a vital role in both the local and global water cycle. "There are significant hydrologic dynamics in weathered bedrock environments, but they are not traditionally investigated because they are hard to access," said lead author Daniella Rempe, an assistant professor in the Department of Geological Sciences at the UT Austin Jackson School of Geosciences. "The study was designed to investigate this region directly."Research led by The University of Texas at Austin has found that weathered bedrock can store a significant amount of rock moisture inside its fractures and pores. This moisture in the layer of weathered rock that is commonly located beneath soils is an important part of the water cycle on the local and global level. Tree roots tap into the rock moisture and release it back into the atmosphere as water vapor, and water flows through the fractures and becomes part of the seasonal groundwater storage (blue arrows). Credit: University of Texas at Austin Jackson School of Geosciences.The researchers discovered that water trapped within the weathered bedrock is able to sustain forest trees through periods of drought even after the top layers of soil have become parched. Field samples taken from a site in Mendocino County, Northern California revealed that as much as 27% of the region's annual rainfall was stored within the pores and cracks of the bedrock as "rock moisture". While the beneficial effects of rock moisture is likely to vary from region to region, and also according to topography, the researchers believe it explains how trees in this area were not affected by the severe drought experienced between 2010 and 2015, which killed over 100 million trees across California. "How trees can survive extended periods of severe drought has been a mystery," said Richard Yuretich, director of the National Science Foundation's Critical Zone Observatories program, which funded the research. "This study has revealed a significant reservoir of trapped water that has gone unnoticed in the past. Research of this kind can help greatly in managing natural resources during times of environmental stress." For the study, the team monitored rock moisture content of nine well points drilled into the weathered bedrock that were sited on a steeply sloping hillside covered in forest from 2013 to 2016.Lead author Daniella Rempe, an assistant professor at the Jackson School of Geosciences, with a deep borehole drill at the research site. The research team used the drill to make wells to monitor rock moisture. Credit: The University of Texas at Austin Jackson School of Geosciences.They discovered that between 4-21 inches of moisture accumulated within the weathered bedrock layer over the winter rainy season, with some variance between wells. They found that the maximum level of moisture within each well remained roughly the same for the duration of the study, including during a year that experienced significant drought. This major finding suggests that the amount of rainfall experienced in the winter dry season is irrelevant, and the total amount of rainfall has little impact on the level of rock moisture that accumulates in the bedrock. "It doesn't matter how much it rains in the winter, rock moisture builds up to the same maximum value," Rempe said. "That leads to the same amount of water every summer that's available for use by trees." When comparing average moisture levels between bedrock and surrounding soil, the research team found that rock moisture levels in all wells were higher than soil moisture for all locations monitored. While Rempe believes that moisture held within soil is important, the underlying bedrock could play a greater role in determining whether an area is going be water stressed during periods of drought. Rock moisture that is taken up by trees can potentially be evaporated from tree leaves into the surrounding air, or it can trickle down through cracks in the rock into the groundwater below. Consequently, it could play a wider role in the environment as well as climate. According to Zong-Liang Yang, a colleague of Rempe's who did not take part in the research, this study highlights the need to incorporate rock moisture in hydrological and global climate models.

    • How Energy is Linked to the Water Crisis in Cape Town — and Why American's Should Care

      An article recently published by the Environmental Defense Fund highlights how water and energy are inextricably linked. Cape Town, a major South African city, is counting down the days to Day Zero, when the city's taps, which provide 4 million inhabitants with water, are expected to run dry. While extreme water restrictions and water saving measures have pushed the date back from April to November 2018, the fact remains that the city's water supply is still extremely precarious."Yet, while this water crisis has been making headlines worldwide, nobody's talking about the connection between water and energy," says Kate Zerrenner, Senior Manager, Energy-Water Initiatives at the Environmental Defense Fund. "In a rapidly changing climate, we should."According to a 2014 study, Cape Town is not the only water-stressed city in the world — the water supply of one out of every four larger cities around the world, including two or more US cities, is under duress. Zerrenner points out that many of these cities also happen to depend on coal — the world's thirstiest source of energy.The supply of water and energy go hand-in-hand, an association referred to as the energy-water nexus. Energy is used during water treatment processes and to pump water across the distribution network, while water is consumed during the production and supply of energy. Consequently, our choice of energy has a direct impact on our freshwater resources. Conventional sources of power such as natural gas, coal and nuclear energy use an average of 25 gallons of water for every kilowatt-hour of power produced, with coal being the most water hungry, or in this case thirsty, using between 20-60 gallons to produce a kilowatt hour of electricity, depending on the cooling technology employed at the power plant. Back home in the US, the average household uses around 900 kWh of electricity a month, which equates to roughly 23,000 gallons of water every month. That's just to meet the power needs of a typical American household, and doesn't account for water used for drinking, cooking, showering/bathing, dishwashing, laundry, flushing, etc, etc. In Cape Town's case, 92% of the country's energy is supplied by coal. So even though residents in Cape Town and further afield have drastically cut back on their water usage during the prolonged drought currently affecting the region, the power plants that supply the country with energy continue to guzzle it up. Will US Cities Be Next? Climate change is causing unprecedented shifts in temperature and rainfall patterns across the world, including America, where many areas are already becoming hotter and drier. Texas is once again feeling the effects of drought, while California has suffered an extended period of drought that has already severely impacted California's agricultural sector. As these dry conditions extend eastward, more and more areas are becoming water stressed, with Miami considered one of the first US cities that could run out of water, largely due to contamination of it aquifers by saltwater intrusion from the ocean. Perhaps now is a good time to reassess the energy-water nexus, and make decisions that could help us save the precious little water remaining. Water-efficient Power Sources The good news is that there are water-efficient alternatives to water-hungry power sources. These come in the form of clean energy, such as solar and wind power, which both use practically zero water. What's more, they are cleaner, and therefore better for the environment too. By the same token, energy-efficiency uses no water at all. In the US, 85% of electricity is still supplied by water-hungry fossil fuels and nuclear. By simply improving energy efficiency and expanding solar and wind energy to meet more of the country's energy needs, while steadily reducing our dependence on more water-hungry sources of power, we can save huge amounts of water at a time when we are going to need it most."This is our opportunity here and around the world as we plan for the reliability and resilience of our energy and water systems. It's no longer possible to ignore the impact our energy sources has on critical water supplies, and vice versa," says Zerrenner. "We have already begun to turn toward a cleaner energy economy. The question now is whether we can ramp things up
