    • Does Glyphosate Pose a Health Risk in Drinking Water?

      In August 2018 a jury awarded a dying man $289 million in damages after he claimed glyphosate in Monsanto's common weed killer, Roundup, caused his terminal cancer. Dewayen Johnson, a school groundsman in Benicia, California was diagnosed with non-Hodgkin's lymphoma back in 2014. This landmark lawsuit sets a precedent for over 5,000 plaintiffs across the country filing similar lawsuits. Glyphosate, the active ingredient in Roundup, is a non-selective herbicide that was discovered in 1973 and commercially produced in 1974. Today it is the most widely applied agricultural chemical on the planet. A 2015 study published in Environmental Sciences Europe revealed that since coming into production in 1974, an alarming 9.4 million tons of glyphosate has been applied to crops and agricultural fields across the world, 1.8 million of which where applied to crops grown on American soil.A bottle of round-up pesticideBecause this chemical is so heavily used, and its use is so widespread, it raises some very important questions. Can it get into our drinking water, and if so, what are the health implications? The guide below outlines some of the key issues to help you better understand your risk of exposure via your drinking water; explaining how glyphosate can get into your drinking water, and whether it poses a health risk to you and your family if it does. How does glyphosate get into drinking water? A 2007 report, titled Public Health Goal for GLYPHOSATE in Drinking Water, suggests that while glyphosate shows an affinity to soil, it can leach into surface water bodies and groundwater systems via two primary pathways: 1) When the herbicide is blown into water bodies that lie adjacent to fields sprayed with Roundup; and 2) Via runoff when sprayed fields are irrigated, which can contaminate water bodies further away. Because glyphosate is stable in water, it does not readily degrade, but rather persists in the aquatic environment. The most likely route of exposure to humans is by directly inhaling or through skin contact with the chemical, or indirectly by drinking water contaminated with Roundup, or consuming crops that have been sprayed with it.Crops being sprayed with the pesticide glyphosateWhile the majority of lawsuits currently underway involve plaintiffs who were directly exposed to Roundup after using the product in their gardens, school yards or farms, there have been instances where drinking water facilities have reported glyphosate levels that are higher than the EPA's safety standard for drinking water (0.7 mg/L or 700 ppb) and the much lower level recommended by the Environmental Working Group (0.5 mg/L or 5 parts per billion). In effect, people living in the communities these facilities serve potentially now face a a greater risk of developing cancer than people not exposed to glyphosate in their drinking water. Does exposure to Glyphosate in drinking water pose a health risk? While Monsanto maintains that Roundup does not cause cancer, the International Agency for Research on Cancer (ISRC) thinks otherwise, listing glyphosate as a Group 2A chemical, meaning it's "probably carcinogenic to humans". Animal studies show a link between cancer and exposure to glyphosate, while the limited observations on humans show that exposure is associated with the development of non-Hodgkin lymphoma. Exposure to glyphosate is also linked to kidney disorders, problems with the reproductive system and impaired fetal growth, as well a disruption to the endocrine system. The best way to ensure the water you drink is free from potentially harmful glyphosate is to filter it with a good quality drinking water filter. Black Berkey filters have been tested to remove glyphosate to below lab detectable limits of >75%, which was the limitation of the testing equipment — the actual removal rate may be much higher.

    • Is Distilled Water Safe to Drink?

      Distilled water basically refers to any water that has undergone purification using the process of distillation — where water is heated to boiling point and the water vapor (steam) that forms is collected. Any contaminants such as chemicals and metals that may be present in the water remain behind. As a result, the water vapor collected is much purer than the original water. But is distilled water safe to drink? Well, yes and no. It depends on how you look at it, and what you consider safe. Because distillation is effective at removing most contaminants, it is usually safe to drink water that has been treated in this manner. The water produced will be purer and safer than the original water source. However, distilled water may not always be safe to drink. It depends largely on the quality of the source water being treated. For example, treating non-potable water that contains high levels of industrial contaminants may produce distilled water that still contains harmful pollutants at levels high enough to pose a risk to human health. Side Note: If you would like to see how a comparison of the berkey water filter vs distilled water, this article will help you.An example of double distillationDistillation Removes Beneficial Minerals While the quality of distilled water will certainly be much higher than the original source water, the major drawback to drinking distilled water is that many of the essential minerals that are naturally present in water, such as magnesium and calcium, are unstable and are therefore released during the distillation process. As a result, distilled water may lack beneficial minerals typically found in spring- and mineral water, or other natural water sources. Lets look at the implications of this a little closer. Effect on Taste Because the vitamins and minerals have been stripped during the distillation process, distilled water tends to have very little taste, or worse still, if sold in plastic bottles, often tastes like plastic. This is because minerals that are normally present in drinking water help to keep the water tasting fresh. Furthermore, it may absorb harmful chemicals used to manufacture plastic such as BPA, an endocrine disrupter associated with neurological disorders, infertility, blood disorders and cancer to name a few. Some distilled water producers package their products in glass containers to avoid this.Causes Mineral & Electrolyte Deficiencies in the Body Drinking distilled water can deprive your body of beneficial minerals that are essential for our health and wellbeing, as minerals lost, for example in perspiration, are not replenished when you drink water; you are simply rehydrating. Also, because electrolytes — which are important for waste elimination and healthy body functioning — move from your body (where they are in a high concentration) to the mineral-free water (where they are in a low concentration, or rather non-existent), your electrolyte levels will gradually decrease, eventually leading to an electrolyte imbalance. Increased Acidity Because distilled water contains no minerals, it readily assimilates other compounds. For example, when it mixes with air it can absorb carbon dioxide, which will cause the water to become more acidic. While consuming acidic water in itself is not necessarily dangerous, experts agree that alkaline water is better for us and that consistently drinking acidic water can pose several health risks, including osteoporosis and cancer. Changes the pH of Blood and Body Tissue Distilled water has a pH of 7.0, while the pH level of blood needs to be between 7.35 and 7.45. Should blood pH levels drop below that, the blood and body tissues can become excessively acidic — a condition known as acidosis. Significant imbalances in minerals, electrolyte and pH levels can result in nutrient deficiencies, muscle cramps, fluid retention, fatigue, headaches, impaired heart rate, as well as other potentially harmful health effects. According to the World Heath Organization (WHO), any drinking water that has been demineralized during treatment — including water treated by reverse osmosis, nano-filtration, desalination and deionization — will have the same health pitfalls as distilled water, unless that water is remineralized. So, while distillation is a simple, cost-effective method of purifying water, making it safe to drink in the short-term, long-term consumption is not recommended as your body will lose essential minerals and electrolytes that are important for normal healthy body functioning. The most effective way of removing contaminants from drinking water without stripping the water of essential minerals is filtration. Using a high-end portable home water filter, such as those in the Berkey range, you can effectively remove a wide range of harmful contaminants while still retaining the minerals and nutrients that not only give water its fresh, awesome taste, but which your body needs for good health.
