  • A Pilot Survey of In-Service Home Arsenic Tracked in from Chromated Copper Arsenate–Treated Decks

    Arsenic is a known carcinogen. It is also known to be readily dislodgeable from chromated copper arsenate (CCA)–treated lumber. The floors of in-service homes were tested for inorganic arsenic using a wipe method similar to the U.S. Housing and Urban Development (HUD) method for lead dust clearance sampling. Additionally, a hand-sampling method was used that involved direct dermal contact with ...

  • Arsenic removal from groundwater using low-cost carbon composite electrodes for capacitive deionization

    Affordable carbon composite electrodes were developed to treat low-concentrated groundwater using capacitive deionization (CDI). A carbon slurry prepared using activated carbon powder (ACP), poly(vinylidene fluoride), and N-methyl-2-pyrrolidone was employed as a casting solution to soak in a low-cost porous substrate. The surface morphology of the carbon composite electrodes was investigated ...

  • The Use of NDT for Surface Defects

    Nondestructive testing (NDT) for surface defects requires solutions that can effectively probe complex surfaces that are rough or include tight corners. Therefore, technicians need a surface-oriented approach—such as eddy current array (ECA)—that can easily overcome the challenges of unconventional contours.  However, ECA technology alone is not enough to get the job done. ...

  • Extensive Solutions for Removing Arsenic from Your Drinking Water

    You may not be aware that your water supply has unsafe levels of arsenic in it. If testing proves this to be the case, you must immediately find a form of arsenic water treatment to help you have access to clean drinking water again. Arsenic is a poisonous substance that has innumerable negative health effects on humans. There are several methods of performing arsenic removal from ...

  • Reasons You Should Invest in an Arsenic Water Treatment System

    In many areas of the U.S., the element arsenic makes its way into the water supply. This element can have adverse health effects. Although it’s rare that it shows up in large enough concentrations to be fatal, it can still cause problems and should be eliminated. Health Effects Many studies have been done to determine the specific effects of consuming water ...

  • The 5 Benefits of Professional Arsenic Removal from Water

    It is a sad and scary truth, but many homes have arsenic in their water systems. High levels of arsenic can be dangerous to you, your family, your pets, and the property you inhabit. Do not panic, though. Simply research an arsenic filtration system. There are many advanced methods that can be used to remove arsenic from water. Arsenic in water removal is completely affordable and safe. ...

  • Characterisation of arsenic contamination in groundwater by statistical methods

    Statistical investigation on groundwater arsenic concentration data of southwest Bangladesh was performed. Two data sets of 1998–99 and 2002–03 were selected for this analysis. Summary statistics of the data shows that the mean concentration exceeds the Bangladesh limit (0.05 mg/l) in all areas. Normality of arsenic concentration data was checked by frequency histogram, skewness coefficient and ...

  • Updating national standards for drinking-water: a Philippine experience

    The latest version of the Philippine National Standards for Drinking-Water (PNSDW) was issued in 2007 by the Department of Health (DOH). Due to several issues and concerns, the DOH decided to make an update which is relevant and necessary to meet the needs of the stakeholders. As an output, the water quality parameters are now categorized into mandatory, primary, and secondary. The ten ...

  • Removal of As from groundwater by in situ bioprecipitation and zero-valent iron

    The aim of this study was to evaluate the in situ bioprecipitation (ISBP) and zero-valent iron (ZVI) for removal of arsenic from groundwater. Batch experiments were set up to test the metal/oxyanion removal efficiency using the processes induced by ZVI, by ISBP and by combining both technologies. For the construction of microcosms in anaerobic condition, aquifer material was mixed with ...

After two months of acclimatization the biomass was able to remove ammonia to below 1 mg/l and phenols and thiocynate ...

  • What You Should Know about Arsenic Treatments

    The nutrients that you put into your body directly impact your health. If you consume water with harmful substances, bacteria, or metalloids, it could create serious issues. While not a metal, arsenic is considered a metalloid because it contains many of the same properties as metallic elements. Typically found in soil, arsenic is harmful when ingested. Unfortunately, many Americans unknowingly ...

  • How to Deal with Arsenic in Drinking Water

    Thanks to recent developments in technology, daily drinking water undergoes a rigorous treatment process for water to be consumable. This is because most ground and natural river waters have a chemical in them called arsenic. Arsenic is a metallic chemical element that is found commonly among rocks and sulfur in the Earth’s crust. Arsenic is known for getting into your drinking water from ...

  • Arsenic removal by ferric-chloride coagulation – effect of phosphate, bicarbonate and silicate

    Jar tests with synthetic water were carried out in order to investigate the effect of phosphate, bicarbonate and silicate on arsenic removal efficiency by in-situ formed ferric hydroxide.
