What is Arsenic?
Rocks and soil naturally contain arsenic along with many other elements and are distributed throughout all continents. Groundwater that is used for drinking water may sometimes include small quantities of arsenic that has been dissolved and is above drinking water standards. Your chance of developing cancer and other major health issues might rise if you drink water that contains arsenic. It’s critical to understand how much arsenic is present in your water supply and how to lower your exposure.
Health Effects of Drinking Arsenic Water
Drinking water with low arsenic over a long period of time could lead to diabetes and a higher risk of bladder, lungs, liver, and other organs. Arsenic can also cause sores, discoloration, and the growth of corns on the skin. It can also cause cardiovascular and respiratory disorders and lower IQ in children. Arsenic exposure can have long-term negative effects on your health, especially if you are exposed to it at low levels over an extended period.
How to Protect Yourself and Your Family
The recommended level of arsenic in drinking water in the United States is 10 micrograms per liter (g/L). * However, long-term exposure to water containing arsenic at levels below the U.S. Environmental Protection Agency (EPA) threshold can still raise your chance of developing cancer. The EPA has established a Maximum Contaminant Level Goal (MCLG) of 0 g/L for arsenic in drinking water as a result to prevent long-term exposure and risks. This goal does not consider the cost of water treatment to completely remove arsenic from drinking water due to many limitations and high costs associated.
• 1 part per billion (ppb) is equal to 1 microgram per liter (µg/L)/(ppb).
Public Water System & Private Well Water System
Drinking water standards established by the EPA have a 10 µg/L (ppb) limit for public water systems servicing locations where people reside, work, attend school, and get childcare. These systems take action to reduce arsenic if levels exceed the standard. However, to reduce the Arsenic level to 0 µg/L (ppb) is mostly recommended to not extend the consumption of long-term small dosage of arsenic in drinking water.
Compared to the private well water system, which is not regularly tested, Arsenic should be tested regularly to make sure there is no Arsenic in well water or breakthrough (>10 µg/L /ppb) in arsenic in well water. The treatment of well water could be achieved through a Point of Entry (POE) system for the whole house or a Point of Use (POU) system. Ideally, the Point of Entry (POE) system would be best suitable to limit all exposure to Arsenic but is associated with higher costs compared to Point of Use (POU) system.
Sources of Arsenic
Arsenic may naturally dissolve into groundwater and is present in soil and rock. The source of arsenic’s biggest hazard to human health remains in groundwater. Many nations, including Argentina, Bangladesh, Chile, China, India, Mexico, and the United States of America, naturally have significant quantities of inorganic arsenic in their groundwater and require special treatment to remove large quantities of Arsenic. The sources of exposure are drinking water, crops irrigated with polluted water, and food cooked with contaminated water.
Other food sources of arsenic include fish, shellfish, pork, chicken, dairy products, and cereals, however exposure from these sources is often considerably lower than exposure from polluted groundwater. Arsenic is mostly present in seafood in its less hazardous organic form.
The most dangerous form of arsenic is inorganic, which is the one that may be found in contaminated drinking water. It may also be present in meals like rice, cereal, and other grains.
The most prevalent form of arsenic in food is organic. Compared to inorganic arsenic, it is more prevalent in fish and shellfish and less detrimental to human health. Human activity is partly to blame for some of the arsenic in the environment. Some insecticides include arsenic, which was also employed as a wood preservative for wooden decks, foundations, and playground equipment for kids.
Solution to Reduce Arsenic in drinking water
If you have well water with high iron content, Katalyst-Light® would be able to remove your iron completely along with coprecipitation of As/Fe.
High treatment cost is associated with providing public water with 0 µg/L of arsenic. Therefore, take actions into your own hands and use effective Adsorbtion filter materials to remove arsenic completely and avoid all exposure to arsenic.
The best available technology for arsenic removal is Adsorbtion due to its high capacity and efficiency. reverse osmosis or resins are not a suitable solution due to the high wastewater associated and recontamination of the environment.
Titansorb systems could be designed with all local water treatment components and deliver arsenic free drinking water quickly and economically. Following photo of school children in Bangladesh enjoying the economical system of Titansorb for arsenic free drinking water is certified by the Water Quality Association (WQA) to NSF/ANSI/CAN 61 Drinking water Standards.
