Big Berkey Water Filters

In what appears to be another damning blow to water fluoridation, a recent study found blood fluoride levels significantly higher in patients with a rare bone cancer called Osteosarcoma when compared to control groups.  Prior studies have made similar claims and seem to reinforce these findings.   Let’s hope this makes more people aware of the critically important fluoride debate.

Rainwater collection for drinking is a growing trend in the United States.  Many seem to be experimenting with rainwater collection as part of their own crusade for self sustainability and emergency preparedness.  Others give it a try as an alternative to their main water source and and to take advantage of the potential money savings.  However, in many parts of the US and the world, rainwater collection is the primary and sometimes only source of drinking water.  It’s a rather straightforward design you can build yourself, but some basic guidelines should be followed for guaranteed success.  Most importantly, if you’ll be drinking your collected rainwater, you must ensure that your water flows through a filtration system.  Fortunately, filtering through a Berkey Filter system or just the Black Berkeys prior to ingestion is a cheap, easy, and effective method that protects you from potential risks.

Why Collect Rainwater?

For many who are supplied with water from a well or their local municipality, collecting rainwater may seem like an overkill or simply unnecessary.  But with the always existing threat of a natural disaster, peace of mind is gained by knowing that a backup water source is available in the case of broken municipal feeder pipes or damaged well systems.  In the case of a severe drought, wells and water sources to can completely dry up.  More often than not, when rain does come it is not nearly enough to reactivate these sources.  Rainwater collection may not solve all your water needs when a drought hits, but it can provide critical supply in the rare instances of rain.  Camping or remote living locations that do not have access to a water source are also great candidates for rainwater collection systems.

Precautions To Consider When Collecting Rainwater

As water is harvested through a catchment and into the collection system, it will come in contact with surfaces that are unclean. Typical contamination can come from sources such as animal fecal matter(birds, squirrels, etc), roof material chemicals, and other bacteria. To combat this, rainwater collection systems utilize a filtering device to make the water potable. Systems can either run directly through a filter system into a storage tank, or can be collected in a tank to be filtered at a later date. We have some customers who have built a 2 stage system where a 1st stage 5-10 gallon catchment bucket is modified and equipped with 4 to 8 Black Berkey filter elements that drip filtered water into a lower 55 gallon storage catchment. Creativity works well when designing such systems, and the options to suit many homeowners needs are endless.

To understand the differences between the Super Sterasyl Ceramic filter and the Black Berkey purification element, it helps to have a brief history on the evolution of the business. Essentially, the Super Sterasyl filters are an evolution of ceramic filter technology originally discovered in 1827 by Henry Doulton in Britain. Over the years, the Doulton company made noteworthy improvements upon the ceramic filters by introducing methods for bacteria removal and self sterilization. Once these improvements were incorporated, gravity filters became heavily used by military forces, relief organizations, and missionaries who lacked access to clean water. The general public also took note and the Doulton company built it’s core business around this Super Sterysyl Ceramic filter technology. Eventually In 1985, British Berkefeld was acquired by Doulton and continues to sell these ceramic filters across the world to this day.

Through a distribution partnership with Berkefeld, the US based company New Millennium Concepts gave North American residents the opportunity to purchase the Super Sterysyl Ceramic filter product locally. New Millennium Concepts then built upon this filtration franchise by designing and creating the Black Berkey Element and expanding the lineup of Berkey housing systems and accessories. Designed over a decade ago, the Black Berkey is a proprietary combination of approximately 6 different types of media designed to take filtration to the next level. They exceed EPA log 7 ANSI / NSF protocols for filtration and thus are rated as water purifiers.

Without going into too much detail, from a filtration perspective the Black Berkey’s filter out the same chemicals and contaminants that the Super Sterasyl Filters do, but go above and beyond by removing Lead, MTBE’s, and other heavy metals. In addition, since the Black Berkey’s are water purifiers, they will filter out a contaminant like Chlorine to undetectable levels, while the ceramics will only remove > 90% of Chlorine.

The Black Berkeys and the Ceramics and basically the same in terms of life span, cleaning, price, and overall day to day use. While both filters are very durable, the ceramics have a slight edge and may benefit missionaries or those who expect to place daily physical wear and tear on the filter when breaking down the system for transport. In essence, both filters are outstanding performers with a long proven track record and tens of thousands of satisfied customers, however the Black Berkeys are more comprehensive in the array of contaminants addressed and have an advantage in their ability to remove some of these contaminants to a higher percentage.

It’s important to note that if you already own the Ceramics and are looking to address some of these missed contaminants like Lead and MTBE’s, the PF-4’s will remove this in addition to growing public concerns like Fluoride and Arsenic. Along those same lines, if you own or are considering purchasing the Black Berkeys and would like to remove Fluoride and Arsenic, choosing the PF-2’s as an add-on will accomplish this goal.

We see a couple commercials on the TV about some corporation that’s involved in an eco-friendly project and our conscious sets at ease.  The mindset becomes, “we’re on the right environmental path, we’re starting to make change.” The stark reality is that it’s going to take much more for us to right these wrongs as we are still on an environmental downward trend in the US and even more so in developing countries.  While we each have our own part to play in this life, and some may be able help turn the tide more than others, it’s imperative that we at least all fully understand the severe ramifications of our choices and actions. 

Below are promotional clips from an upcoming PBS documentary called Poisoned Waters that is looking like a must see presentation on the environmental impacts of water pollution. It runs for 2 hours and debuts on PBS this upcoming Tuesday, April 21st at 9PM. It will also be available on the PBS website in it’s entirety after the premiere.

Protecting the majority of the US drinking water from disease causing bacteria, viruses, and other microbes, are disinfectants such as chlorine, chloramines, ozone, and chlorine dioxide.  This practice of disinfection has been in place since the early 1900’s, and Chlorine is a chemical that has played a significant role.  Over the past few decades, numerous studies have been conducted by members of the scientific, regulatory, and public communities evaluating the short and long term safety of chlorination. While some have shown no negative effects on human health, there are many that have.

History of Chlorine

Chlorine has made it’s mark on history by virtually eliminating water borne diseases and allowing populations around the world to flourish.  It easily applied at the water source and small amounts have the ability to be effective throughout a municipal distribution network, from the water treatment plant all the way to the faucet tap.  The discovery of these benefits coupled with it’s low cost resulted in chlorine being chosen as the preferred chemical for both domestic and industrial purposes for most of the 20th century.

Concerns Over Chlorine in Drinking Water?

Concerns over chlorine stem from the way in which the chemical reacts with organic plant matter that is naturally present in water, in addition to it’s reactions with saliva and stomach content when ingested.  These chemical reactions result in a group of chemicals known as disinfection byproducts(DBPs).  Some of my readers may be familiar with one of the most notorious byproducts called Trihalomethanes (THMs) which consist of four chemicals: chloroform, bromodichloromethane, dribromochloromethane, and bromoform.  Scientific evidence classifies THM’s as known carcinogens with two types of health effects being shown by studies; organ cancer and reproductive/developmental health effects.  The following paragraphs highlight some of these findings.

World Health Organization Study

Released in 1996, and republished again in 2003, the World Health Organization (WHO) released a study of Chlorine and it’s water reacting equilibrium forms of hypechlorous acid and hypoclhorites and their effect on mice and rats. In these studies, short terms chemical exposure seemed to indicate no negative effects on the mice.  However, 2 year long term rat exposure to sodium hypochlorite in drinking water resulted in a “dose related depression in body weight gain in all groups, depressed liver, brain, and heart weights in males given a .05% dose, decreased salivary gland weights in both female groups, and decreased kidney weights in females given .2%.”  Also shown was that oral administration of Chlorine via hypochlorite ion or hypochlorous acid at 100, 200, 400 mg of Chlorine/liter resulted in “dose-related increases in the amount of sperm-head abnormalities in male mice.”  Towards the end of the WHO Guideline for drinking water quality, under the heading “Effects on Humans”, the WHO study referenced 2 studies reading the following:

“In a study of 46 communities in central Wisconsin where chlorine levels in water ranged from 0.2 to 1 mg/litre, serum cholesterol and low-density lipoprotein levels were higher in communities using chlorinated water. Levels of high-density lipoprotein (HDL) and the cholesterol/HDL ratio were significantly elevated in relation to the level of calcium in the drinking-water, but only in communities using chlorinated water.  The authors speculated that chlorine and calcium in drinking-water may interact in some way that affects lipid levels.”   And, from another study, “An increased risk of bladder cancer appeared to be associated with the consumption of chlorinated tapwater in a population-based, case–control study of adults consuming chlorinated or non-chlorinated water for half of their lifetimes.”

Additional Studies on Chlorine

In the 1960’s, Joseph M. Price, MD performed experiments using chlorine in the drinking water of chickens.   He came back to report that 95% of the chickens given chlorine added to distilled water developed atherosclerosis within a few months. In his book, Coronaries/Cholesterol/Chlorine, Dr. Price presented alarming evidence that Trihalomethanes (THMs), are the “prime causative agents of arteriosclerosis and its inevitable result, the heart attack or stroke.”

In the summer of 1992, the New York Times reported on a study directed by Robert D. Morris of the Medical College of Wisconsin in Milwaukee, compiling 10 separate epidemiological studies from the 1970’s on chlorinated drinking water. Morris partnered with with epidemiologist Thomas C. Chalmers and his colleagues at Harvard to utilize a statistical technique call meta-analysis. They reported that people drinking chlorinated water over long periods had a 21% increase in the risk of contracting bladder cancer and a 38% increase in the risk of rectal cancer.  “I am quite convinced, based on this study, that there is an association between cancer and chlorinated water.“ said Morris.

Taking a Chlorine Shower

According to researcher Bruce Black - Chlorine and Your Shower,  “Taking long hot showers is a health risk–and to a lesser extent baths.  They lead to a greater exposure to toxic chemicals contained in water supplies than does drinking the water.  The chemicals evaporate out of the water and are inhaled.  They can also spread through the house and be inhaled by others. House holders can receive 6 to 100 times more of the chemical by breathing the air around showers and bath than they would by drinking the water.”

Chlorine and The EPA

In official publications, the EPA has concluded that there is evidence to support a potential association between long term exposure to high levels of THMs and bladder cancer as well as suggestions of an association with colon and rectal cancers.  However the EPA notes that health effects data for the reproductive and developmental health effects are inconclusive and do not show causality.  In 1980, the EPA adopted new regulations requiring cities to reduce chlorination by-products (THM’s) in the water to less than 100 parts per billion.  This was later reduced by the EPA to 80 ppb in 1998.

The position of the EPA is that scientific data proves that the benefits of chlorinating our water far outweigh the risks associated with THM’s and other byproducts. While this can be considered a rational regulatory stance, there is insufficient data examining the safety of exposure to THM’s on a daily basis over decades, and as a result questions it’s strength.   It is not whether THM’s are carcinogenic, this has been established, but rather, is the average individual ingesting enough THM’s through their drinking water for it to be considered a risk.  Unfortunately, our regulatory agencies have not addressed the interaction of chlorine and THM’s once they enter the body.  It is known fact that a weak carcinogen has the potential to be converted to a strong cancer causing agent by simply adding another weak carcinogen.  As the human body is increasingly inundated with various forms of toxic chemicals and free radicals from the water, air, and food we ingest, you have to be left wondering whether the set risk intervals are appropriate given the untested myriad of interaction potentials.

On a positive note, the EPA is pursuing stricter standards for monitoring and addressing THM’s.  In a 2006 Texas EPA Public Drinking Water Stakeholder meeting focused on the health effects of disinfection byproducts(DPB), they state as a 2012 goal the following; “Intent of DBP2 [Disinfection ByProducts, Stage 2] – reduce the exposure of customers in areas of the distribution system with relatively high disinfection byproducts (finding the ‘hot spots’)”, with operational objectives for municipality violations such as “Must evaluate distribution operations.  Must describe plans to change things to fix things.” and “Plans to minimize future exceeds.”

How to Eliminate THM’s and That Chlorine Smell!

To address potential long term health hazards, without falling prey to municipality distribution network inconsistencies and slow resolutions, the dependable solution lies in removing THM’s at the point of use.  You can reduce chlorination by-products by putting water in a jug and letting it sit in the refrigerator overnight, boiling water, or aerating drinking water in a blender.  However, these tend to be unrealistic options for the everyday on-the-go person.

Home water filtration is a best fit, and one of the most effective methods for reducing THM’s is through carbon and ceramic filters.  A quality filter will remove that chlorine smell and taste, and also protect the small segment of the population that has chlorine allergies.   A great choice is Berkey filters.  They have the ability to remove Chlorine and THM’s to undetectable levels and do so at a very low cost per gallon.  Click here for a Berkey 101 Overview.

Sometimes you just need a 5 minute overview to quickly get you up to speed on a particular subject. Below, please find what I consider to be the top 10 basics of berkey water filter systems.

1. There are 7 berkey water filter housing models all using the same internal filters. Starting from lowest in price and working our way up; Berkey Light, Travel Berkey, Big Berkey, Berkey Light w/ LED, Royal Berkey, Imperial Berkey, Crown Berkey. The Berkey Light and Travel Berkey are classified as outdoor filter systems, while the remaining are classified as indoor systems.
2. There are 2 types of upper chamber filters; Black Berkey’s and Super Sterasyl Ceramics (7″ and 9″). More filters in the upper chamber results in faster filtration.
3. Ceramics are a tried and true filter with over 100 years of history behind them. The Black Berkey’s are a newer composite of over 6 types of media meant to take filtration to the next level and are rated as a water purifier. Black Berkey’s remove everything Ceramic Filters do, yet go one step further by filtering out MTBE’s, Lead and other heavy metals.
4. There are 2 types of lower chamber filters (PF=Post Filtration); PF-2 and PF-4. Fluoride is a primary target for these filters. PF-2’s function with Black Berkey’s, and PF-4’s function with Ceramics.
5. Total system weight ranges between 6 and 13 pounds. Total system volume ranges between 1.5 and 6 gallons.
6. Black Berkey and Ceramic Filters last 6000 gallons for a set of 2. PF-2’s last 1000 gallons for a set of 2. PF-4’s are to be replaced every 6 months.
7. The average cost per gallon of Berkey Water is 1.7 cents.
8. Systems assemble in approximately 5-10 minutes. Housing cleaning is easy with regular soap and water. Scotchbrite pads clean both the Black Berkeys and the Ceramics.
9. Berkey Customer service is supported by both BigBerkeyWaterFilters.com and the manufacturer, New Millenium Concepts LTD.
10. Berkey Systems are covered by a 6 months manufacturers warranty and Black Berkey’s are covered by a 2 year prorated manufacturers warranty.

It’s no secret that a major selling point of Berkey water purifiers is it’s portable design.  A high quality water filter that you can pick up and carry is a benefit other filtration systems on the market are simply not able to duplicate.   And let’s not forget the sidekick of these systems, the Berkey sport bottle, which customers enjoy as a free item with any system purchase.  Today, I’d like to illustrate the ways many customers are taking advantage of these Berkey products outside of their home and how you can do the same!

The Portable Berkey Filter System

While Berkey filter systems are officially labeled as either an indoor or outdoor system, all of these systems possess the ability to be used in both environments.  The “official” outdoor systems; the Travel Berkey and the Berkey light, are the smallest and lightest of the lineup, however the other four systems; the Big Berkey, Royal Berkey, Imperial Berkey, and the Crown Berkey, work just as well outdoors.   In fact, where bigger groups of people are involved, a larger system is many times the better choice.

What's missing in this picture?

Outdoor Uses for the Berkey Filter System

• Base Camps / Camping: Camping for more than one day?  Having a large system can fulfill needs such as cooking, drinking, brushing your teeth, cleaning/washing your body, and flushing/cleaning wounds.
• Freshwater Boating: Don’t want to install an expensive boat filtration system or tired of dragging bottles of water around?  Simply take an empty system with you.  When drinking water is needed, scoop water off the side of your boat and pour into the upper chamber.  Within 15-30 minutes drinking water is available to all those on board.   (Please, no salt water.)
• RV’s: Don’t trust the potable water source at the RV site, or there’s none available?   Berkey filters work great as a primary or backup system for your travels.   In addition, similar to boats, these filters provide a much lower cost alternative to the full filtration systems.
• Back Country Cabins: Having running water in a back country cabin is many times a luxury.  With a Berkey, find a source of water nearby and fill ‘er up.  Also, try using rain water.
• Hunting Trips: Similar to camping, many hunters go on trips for days at a time and require a base camp filtration system.  Having a light and portable system is a nice feature when setting up and breaking down in quick turnaround is a high priority.
• Recreation Fields: Want to cut down on your carbon footprint?  Berkey systems come in handy at children or adult sporting events like the soccer, softball, football and baseball fields as long as a hose or another practical water source is available.

In all the situations listed above, the Berkey water filter systems were easily broken down and transported.  They weigh between 8 and 13 pounds and the upper-chamber of the stainless steel system is designed to fit into the lower chamber for transport.   Not to mention,  they are easy to clean and durable.

The Portable Sport Berkey Filter

The sport bottle is also another great example of the portable berkey water filter in action.  Why pay $50 to $100 dollars for a portable hiking filter when you can get one that performs just as well for $28.  At 22 ounces and weighing less than 1 pound, the sport Berkey bottle is lightweight and easy to use.   No pumps, or breakdowns to worry about either.   When encountering a lake, pond, or stream, just fill up and start drinking.

Great for long biking trips!

Outdoor Uses for the Sport Berkey

• Hiking: Going for a day-hike but don’t want to lug bottles of water with you, or the camelbak is simply not going to be enough?  As long as you know you’ll be encountering a water source at some point, you’re all set!
• Mountain Biking: Mountain bikers are all too familiar with the high demand for water that this activity requires.  Attach it to your camelbak as a backup!
• Horseback Riding:  Similar to mountain biking and allows for some flexibility for the rider to carry other items.
• The Gym: Don’t trust the gym water or simply don’t like the taste?  Fill that sport bottle up at the water fountain and squeeze filtered water into your mouth between exercises.   It’s as simple as that.

I sometimes wonder what percentage of the population is aware of the ongoing fluoride debate. There’s absolutely a growing voice of dissent over municipal water fluoridation, but how familiar is the everyday citizen?  I know that a good majority of my friends and family are not aware of it. I’ve never heard it brought up on any major news television programs like 20/20 or Dateline.  It seems the majority of discussion is coming from radio programming, local news stations, activist groups, and some select scientific community organizations.

Just last month, I had the privilege to catch an in depth conversation on the subject.  It occurred on one of my favorites programs; Coast to Coast AM w/ George Noory, where Director of the Fluoride Action Network, Paul Connett and leading dentist in the fight against fluoride, Dr. Bill Osmunson dug into the issue for 3 hours.  Here are some clips from the show.

• Pt. 1: Fluoridation Problems - 7.0 Mins
• Pt. 2: Risks and Issues - 8.5 Mins
• Pt. 3: Water and the Fluoride Gamble - 8.5 Mins

If you’re interested in the full show, e-mail me at dan@bigberkeywaterfilters.com.  In the meantime, below are some high level basic facts and information on the subject of fluoridation.

What’s the Debate?

Adding fluoride to the public water systems, otherwise known as fluoridation, has occurred  for more than 60 years in the United States.  Given this basic historical fact, the immediate question that comes to many peoples mind when they are confronted with the debate is;

“If fluoridation is so bad for us, wouldn’t we already have figured it out? Wouldn’t there be mountains of evidence to illustrate the toxic effects?�

Opponents claim that this evidence does exist, and that much of the scientific and government community simply fail to acknowledge it. It’s curiously regarded as a combination of sticking one’s head in the sand along with a fear of taking a stand against conventional baked-in thinking. Among other statistics, defenders retort that the evidence for fluoride benefits is proven by US general population tooth decay reductions in the order of 50-60% since WWII. This statistic is one of the most controversial as these same reductions, over the same time periods, are shown in countries that have never engaged in water fluoridation.

Where Does Fluoride Come From?

Sodium fluoride, used in fluoridation, is a hazardous-waste by-product from the manufacture of aluminum.  It is a common ingredient in rat and cockroach poisons, anesthetics, hypnotics, psychiatric drugs, and military nerve gas.  Fluoride is more toxic than aluminum and studies have shown that fluoride consumption increases the body absorption rate of aluminum by 600%.  There are, however, controls set in place to manage this risk.  The EPA has maximum water fluoridation levels set at 1 ppm (part per million) and every day many of us are given the opportunity to read a warning on the back of our fluoride toothpaste:

“Keep toothpaste out of the reach of children under 6. If swallowed get medical help or contact poison control center right away.�

But, are these controls enough to protect the general population to the serious downside risks?

Harmful Effects of Fluoride

What is not up for debate is that fluoride harms bones, causes stiff joints, encourages skeletal abnormalities, raises the risk of cancer, results in genetic damage, can damage the thyroid, and hampers nervous system function in humans.   Opponents of fluoridation have a real cause for concern given that fluoride acts as a cumulative poison gradually and increasingly affecting the body over long periods of exposure. As a result, potential toxicity becomes a function on how much water is consumed on a daily basis, the individual’s body weight, and the body’s ability to filter and eliminate the chemical.  These are wide margin variables that may allow a relatively large percentage of the population to fall into a toxic range over time.

Recently, there has been government studies that attest to fluoridation dangers.   In 2005, a CDC study showed irreversible enamel fluorosis in 1 out of 3 children.  Then in 2007, the ADA warned parents not to mix baby formula with tap water in the first 12 months of development so as to avoid fluoride intake.  Just recently in June of 2008, the National Kidney Foundation stated the kidney disease patients should be notified of the potential risks of exposure to fluoride.  Unfortunately, many individuals with thyroid disease and other ailments have been complaining about fluoridation without an official government response.

Inherent Problems with Fluoridation

Each year our scientists are getting better at understanding the toxic implications of fluoride, and one point is glaringly obvious.  With water fluoridation, you cannot control the dose ingested, both children and adults are treated with similar doses, and unless the public filters their water, they cannot opt out of this mass medication.  Regardless of where one stands, it’s apparent that legitimate scientific data is challenging the entrenched “all benefits and no-risk” philosophy of water fluoridation, and all parties must openly and fairly revisit this practice.

To see if you may be drinking fluoridated water, you can start here:  CDC Fluoridation Status.  In the meantime, for those who are concerned, Berkey makes a highly regarded and very popular fluoride filter that works in any berkey filter system.  The PF-2 Fluoride/Arsenic Filters are to be used in conjunction with the Black Berkeys. The PF-4 Fluoride Filters are to be used with the ceramic filters.  More information on various system setups can be found here.

Before one can enjoy the first sips from their newly purchased berkey water filter, any system using Black Berkey Purification Elements must be primed to prepare the filters for use.  Fortunately, it only takes a few minutes to do and is rather easy and straightforward.

“But, what if I am only buying the black berkey filters as a backup set for the future?  Once I receive them, can’t I just throw them in the cabinet and forget about them?”

The answer to that question is no if you want to take advantage of the 2 year manufacturer warranty.  Priming before storage will allow you to test the black berkey and verify that there are no defects with the product.  This is extremely important because the clock on the warranty starts ticking upon date of receipt.  If one just threw it into the closet and took it out 3 years later, only to find problems with the filter,  it would be out of warranty.  Even though there is a small chance of product defect, going through the priming exercise up front helps protect your future investment.

Priming you Black Berkey Filter

Whether you are using a Berkey Light, a Royal Berkey, or any of the other Berkey systems that utilize the Black Berkey purification element, priming is required due to the extremely small pores that make up the filter.   These elements need to have water forced through them to clear the air that has been trapped inside the micro fine pores during production.  Begin by opening up your black berkey box and verify that each element has a rubber washer and a wing nut attached to it.  Also inside the box you’ll find your priming button, a tan rubber washer.  It will be thicker than the element washer with a smaller center hole.  See Figure 1.

Figure 1 - Black Berkey with Tan Priming Button

Now, follow the 5 steps of the priming process below (also shown in Figure 3 Diagram) :

1. Start by pressing the tan priming button onto the stem of the black berkey purification element with the small end facing the element.
2. Place the stem of the Black Berkey element between your fingers and press the large end of the priming button against the faucet. (see Figure 2)
3. While holding the priming button against the faucet, turn on the cold water gently, and allow the water to fill the cavity of the purification element.  (see Figure 2)
4. Allow the exterior of the Black Berkey element to sweat beads of water for about 5 seconds.
5. Follow this process for each element you intend to prime and they will ready for everyday use.

Figure 2 - Place Your Black Berkey Up to Your Faucet for Priming

Figure 3 - Black Berkey Priming Diagram

Storage of your Black Berkey Purification Element

Now that your Black Berkey’s are primed, you may either install them into your system and drink away, or you may store them for future use.  If storing, the most critical issue to monitor is that the filters are allowed to fully dry out.

Follow these basic guidelines for storage after priming:

1. Use a dry cloth to remove any excess water from the filters
2. Air dry the filters by laying them out on a cloth on a window sill with good sun exposure.  Preferably, this area should be well ventilated
3. Turn the at least once a day to ensure they are being evenly dried.
4. After approximately 2.5-3 weeks, the black berkey elements should be fully dry.  If sun is not available, please place in warmer parts of your home and allow for longer dry out times.
5. Once fully dry, place you black berkeys in a container or plastic bag that protects them from moisture.  Vacuum sealed is preferred.
6. These filters are now prepped and ready for use when needed.

Following the above steps for priming and storage ensures that you utilize the black berkey elements in the way they were intended and provides a method for you to protect your future investment.  Proper storage gives you the ability to guarantee yourself years worth of clean drinking water with the ease of being able to install them directly into your system immediately when needed.  This is another benefit that many other filtration systems cannot reproduce and speaks to inherent versatility and quality of the Berkey Filter Line.

Considered as one of, if not the biggest, environmental disasters the US has ever experienced, the Tennessee coal ash spill has alarmed many nearby residents, the EPA, and environmental groups across the nation.  Many are calling it the Exxon Valdez of coal ash spills.  Unfortunately, this story seems to have lost most of it’s national press coverage as the new year began.

Coal Ash Spills…

It all began on Dec. 22nd, 2008 when the earthen dike of a coal ash holding pond, owned and operated by the Tennessee Valley Authority(the largest public utility in the nation), broke at the Kingston Fossil Plant.  This dam failure resulted in 5.4 million cubic yards of ash being released into the neighboring community and Emory River.  This national news story was televised on Dec. 26th.

Within 4 days of the spill, the drinking water is safe according to the Tennessee Valley Authority’s official statement.  This seems a little irresponsible given that it was based upon a water sample taken at the Kingston Plant itself, 6 miles upstream of the actual spill.  And maybe we’ll just overlook the fact that a comprehensive water quality survey of a disaster of this scale requires dozens of samples before an acceptable confidence interval can be attained.

Here’s a close up view of the damage from Dec. 27th, 5 days after the spill from a group of local environmentalists coordinated by Appalachian Voices.  Credit John L. Wathen, a Hurricane Creekkeeper; Sandra Diaz, Appalachian Voices’ National Field Coordinator; and Donna Lisenby, the Watauga Riverkeeper for this footage.

Fortunately or unfortunately depending upon your perspective, on Dec. 28th, the public was able to gain some insight into the severity of the spill when the TVA disclosed to the New York Times the amount of toxins it deposited into this holding pond in 2007; in just one year.  How about 2.2 million pounds of toxins including 45,000 pounds of arsenic, 49,000 pounds of lead, 1.4M pounds of barium, 91,000 pounds of chromium and 140,000 pounds of manganese.  This holding pond, before it spilled out into the neighboring land and waterways, contained decades worth of deposits.  Here’s a fun fact - 100mg(.00022 lbs) of arsenic is considered lethal to the human body.  Let me preface by mentioning that there’s many variables that come into play when we discuss drinking water.  Arsenic needs to dissolve fully into the water supply for a true contamination to exist, but this information is relevant because these toxins need to go somewhere.  Coal ash that is not or cannot be cleaned up will seep into the ground with the potential to enter the water table where it may or may not be filtered out naturally by the sediment.  Coal Ash not removed from the water will settle along the riverbed and shoreline, and continually be washed downstream where the toxins will impact the river ecosystems and aquamarine life to a yet unknown degree.

On Dec 30th, the TVA and EPA issued a joint statement recommending that direct contact with coal ash be avoided and that children and pets should stay away from affected areas.  With the laundry list of toxins contained in the ash, this statement was literally a week late and it’ll probably leave the TVA a billion dollars short as a result of the lawsuits that began piling up last week.  Erin Brockovich even decided to march into town on Jan 8th, and for those of you that saw the movie, you know the TVA couldn’t of been too excited about that visit.

Coal Ash Spill Early Test Results

As you probably have guessed by now, results from some of those water tests have come in.  On the whole, samples from drinking wells and from public drinking water have been found to be within safe levels, however tests of surface and river water closer to the spill showed unsafe levels of some contaminants.  Preliminary tests from the Appalachian Voices samples conducted by Appalachian State University showed arsenic levels from the Kingston power plant canal testing at nearly 300 times the allowable limits in drinking water.  Another sample from two miles downstream revealed arsenic at about 30 times the limit.   Lead, chromium, and other heavy metals were also found to be at elevated levels from these prelim tests.   On Friday, Jan. 2nd,  the EPA came back with some water sample results also.  Sediment and surface water samples near the spill were confirmed to contain high levels of arsenic with one sample containing more than 149 times the maximum state level.  Most recently, on Tues, Jan. 6, the EPA found that two out of 16 water samples exceeded the Tennessee Water Quality Criteria for Domestic Supply.

One of the great unknowns is to what extent the drinking water for surrounding spill land areas and citizens downstream of the Emory, Clinch, and Tennessee rivers will be in the mid to long term.  Since the Emory river eventually dumps into these other two rivers, any contaminants found in the Emory river has the potential to have a downstream impact.  This is a serious concern as the Tennessee river is a major source of drinking water for millions of people.  For their part, the TVA stated that they would be erecting a rock wall, or weir dam, to filter out fly ash from water that flows down the Emory River into the Clinch and Tennessee rivers, but as of Dec. 30th, this had not yet taken place.  That’s at least 8 days of downstream free flow, and I’m guessing here that those early days are the most critical in a spill such as this.  Complicating the clean up efforts just this week, the region has been hit with heavy rains and flooding that has washed more of the ash into areas that were yet to be quarantined or protected.

The Cleanup and Future of East Tennessee

As of writing this article on Jan 11th, there still seems to be many unknowns as the TVA, the EPA, environmental activists, and local citizens work together and butt heads on the physical clean-up, short to long term safety monitoring, and general environmental remediation.  Seeing and reading about local environmental groups and citizens coming together to work through this disaster has given many, including myself, a sense of hope.  But, this is the beginning of a long journey.  Municipal water filtration systems should be able to address spill toxins that may contaminate city water sources.  However, well water drinkers will need to be a little more weary and pay close attention to well test sampling results as seepage contamination takes more time to become evident.  The EPA is recommending that residents on well water either not drink their water at all until more tests are conducted or filter their water.  As for the aquamarine, plant, and animal life, their options are limited and it’s evident that they’re paying the biggest price of us all.

In a unfortunate coincidence, Jan. 9th revealed another gypsum slurry spill in NE Alabama at the Widows Creek coal fire plant owned by none other than the TVA.  This one was much smaller at only 10,000 gallons compared to the 1 Billion gallons in TN.  I’m starting to think that we may have a bigger regulatory problem on our hands here.  There are 156 Coal Fire Plants in the US, and they are all virtually unregulated when it comes to coal ash waste disposal.  Senator Barbara Boxer, a California Democrat and chair of the Senate Environment and Public Works Committee said it best to the CEO of TVA, Tom Kilgore, at the recent Jan. 8th congressional committee hearing, “You need to have a plan to clean this spill up and you don’t have it yet. People will never feel safe there again.”
