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.

    • EPA Funds Largest Citizen-Science Based Water Quality Research Project

      A grant from the US Environmental Protection Agency has given the engineering team from Virginia Tech who exposed the Flint water crisis the funding to allow them to conduct their detective work in other communities that may be affected by lead contamination. According to a report in The Roanoke Times, Marc Edwards, a civil engineering professor at Virginia Tech, has been awarded an EPA grant of nearly two million dollars to detect lead in public drinking water, and to implement measures to control lead levels in drinking water by getting members of the public involved with ongoing monitoring operations.According to Edwards, this funding will enable him and his team to coordinate the "largest engineering citizen-science project in American history."The EPA grant, which covers a three-year period, will provide the necessary support for his team, as well as collaborators from Louisiana State and North Carolina State Universities.Dr. Marc Edwards, an engineering professor at Virginia Tech, and an expert on municipal water quality who had been sent to study the water supply under a National Science Foundation grant Edwards has received wide recognition for his contribution to exposing the Flint water crisis resulting from lead contamination of the local drinking water supply. He plans to create a model that can be applied widely to enable communities to test their own drinking water.9Edwards' laboratory already tests water samples from various parts of the country. However, the funding provided by this grant will give Edwards the financial resources to identify other communities suffering from water quality issues that puts the health of its residents at risk; particularly communities that have until now been neglected. The funding will also be used to test home water testing kits to identify the most effective solution for detecting water quality problems at home. LeeAnne Walters, an environmental activist who recently won the Goldman Environmental Prize for grassroots environmental activism, approached Edwards for assistance regarding Flint's water quality. Edwards together with his team of students and colleagues from Virginia Tech helped the local community test their water in the hope of identifying where the lead contamination was coming from. Edwards found that the city's drinking water supply became contaminated with dangerously high levels of lead after municipal officials switched to an alternative water source in 2014 in an effort to save the city money. This in turn led to a health crisis, after Mona Hanna-Attisha, a pediatrician from Michigan, found elevated levels of lead in children living in the city. The Flint case highlighted the problem of aging water systems across the country, and resulted in a state of emergency being implemented, together with public officials responsible for the crisis being criminally charged for their role. Edwards said that the Flint experience has provided his team with a model that they will continue to use moving forward, and that the EPA grant would be a big help, joking that the funding would help the project "to lose money a little less quickly."

    • Clear Water in Lakes May Actually Mean Poor Water Quality

      Don't judge a book by its cover, and by the same token, don't judge the quality of a lake by its clarity. Lakes dotted around agricultural hotspots typically tend to be bright green in color. This is largely due to phytoplankton and algal growth fueled by nutrients (nitrogen and phosphorus) present in agricultural fertilizers, which get washed into rivers and lakes with runoff. However, after analyzing water quality data collected from 139 lakes located in agricultural hotspots of Iowa over a 13 year period, scientists found that even though lakes had high concentrations of nutrients, they were remarkably clear. Aerial view of a small lake near the city of Clear Lake, Iowa, which represents typical landscapes surrounding the lakes in this study. About 92 percent of land within Iowa is in production agriculture and crops on these lands receive large amendments of nitrogen as anhydrous ammonia and phosphorus. Excessive algae growth caused by these nutrient inputs have turned many of the lakes in this region bright green. Surprisingly, a number of lakes in this study were clearer and appeared bluer than expected, yet are far from healthy. The study authors hypothesize that very high nitrogen levels, often >10 mg/L, suppress high chlorophyll (algae) concentrations. The study, which was recently published in the scientific journal Inland Waters, shows that the excessive fertilizer added to the lakes from agricultural runoff was so high that it killed chlorophyll containing phytoplankton and algae, which typically give polluted lakes the bright green color. According to lead author, Chris Filstrup, a research associate at the UMD Large Lakes Observatory and Minnesota Sea Grant, it is dangerous to mistake an increase in water clarity for an improvement in water quality, as in actual fact, the opposite is very often true. Water quality in clear lakes with high levels of nutrients is worse than that of lakes where more algae is present, yet nutrient levels are lower. Water clarity is often used to measure water quality, yet this study suggests this approach may not necessarily be appropriate for all regions. Nutrient levels rise to excessive levels after nitrogen and phosphorus from surrounding agricultural fields, animal feed lots, suburban gardens and urban landscaping gets washed into rivers and lakes with rain and melted snow. Yet, while these nutrients generally spur algal growth, they can in fact kill algae when concentrations become excessive. "In some of the Iowa lakes in our study we noted phosphorus levels 10 times what we'd expect to see in a northern Minnesota lake," said Filstrup. "We were astonished to see that the nitrogen levels were more than 30 times higher." When nutrient levels become so extreme they kill phytoplankton and algae present in the waterbody, making the lake appear clearer. In the same way that applying excessive amounts of fertilizer to soils can harm plants, rendering the soil barren, excessive amounts of nutrients in freshwater systems can kill water plants, effectively ridding lakes of algae, thus improving water clarity. "We thought that the low appearance of algae at high nitrogen concentrations might be due to imbalances of other nutrients, or too much shade for algae to grow, or that some algae are less green or that zooplankton eat more algae when there's a lot of nitrogen," said co-author John A. Downing, director of Minnesota Sea Grant, a scientist at the UMD Large Lakes Observatory and a professor in the UMD Department of Biology. "But none of those hypotheses panned out. The only explanation that makes sense, so far, is that high nitrogen is bad for algae." According to the scientists, the decrease in algae in these lakes is most likely caused by an interplay of nitrogen, phosphorus, sunlight and the landscape, which in combination can cause the excess nitrate particles to form reactive oxygen species that burst the cell walls and cell membranes of algae, damaging or killing them. According to Filstrup, its a bit like pouring hydrogen peroxide onto a wound. The hydrogen peroxide bursts the bacteria, making the wound fizz. A similar reaction occurs within lakes, but while there is no fizz, the reactive oxygen species that forms from nitrate can kill organic matter, including algae and phytoplankton. As the increased demand for agricultural crops continues to rise, along with the application of fertilizers to stimulate rapid growth of commercially produced crops, the scientists hope their study will provide some insight to other agricultural regions where extreme nutrient loading may be a cause for concern. Downing suggests that excessive application of nitrogen based fertilizers is not only a waste of money, it also leads to unhealthy freshwater systems, and ultimately also causes ocean dead zones such as that in the Gulf of Mexico. It is therefore important that we grow crops and manage animals wastes appropriately to avoid polluting and degrading the environment. Journal Reference Christopher T. Filstrup, John A. Downing.
