  • A Trace of Arsenic

    The cans of baby formula invaded Brian Jackson’s Dartmouth College lab late in 2010. His team picked up an armful of popular brands at the food co-op in Hanover, N.H. Then another armload. Eventually Jackson had a cabinet full of the brightly labeled canisters. Today, he still keeps a few in his office. Not as clutter — that’s not his style. He just likes to keep his toxicology ...

  • Plant algae method for arsenic removal from arsenic contaminated groundwater

    Field studies were carried out in Urumqi River Basin in Northwest China. The study focused on experimentation on a plant algae method that was tested by taking various water chemistries into consideration. The results from a greenhouse experiment evaluated for four doses of P (0, 100, 200, and 300 μmol/L) using two ferns (30 and 60 day old) on 15 L of contaminated groundwater per plant revealed ...

  • 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 ...

  • How to Treat Water and Remove Arsenic

    Arsenic is a naturally occurring element from the earth’s crust. Around the world, many countries have groundwater that is steeped in arsenic. Until recently, governments haven’t realized just how bad arsenic was for people, even in minute concentrations. In 2001, the US Environmental Protection Agency felt it necessary to lower the drinking water arsenic standard from 50 parts ...

  • 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 ...

  • Guide to Removing Arsenic from Drinking Water

    It’s said that the human body is made up of almost 60 percent water. Is the water you’re putting into your body pure? Many people are unaware of the chemicals and compounds that are seeping into their drinking water and wreaking havoc on their internal systems. Arsenic, for example, can be found in many different areas. In the Northeast especially, well water is more likely to be ...

  • 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 ...

  • 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. ...

  • Reduction in exposure to arsenic from drinking well-water in Bangladesh limited by insufficient testing and awareness

    This study considers potential policy responses to the still very high levels of exposure to arsenic (As) caused by drinking water from shallow tubewells in rural Bangladesh. It examines a survey of 4,109 households in 76 villages of Araihazar upazila conducted two years after a national testing campaign swept through the area. The area is adjacent to the region where a long-term study was ...

  • 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 ...

  • Minimizing Arsenic Leaching from Water Treatment Process Residuals

    Ferric chloride addition was investigated for treatment of As-laden spent regeneration brine from ion exchange processes. Furthermore, varying conditions and calcium addition were investigated for the stabilization of the resulting As-laden solids. Arsenic, sulfate, bicarbonate, and chloride concentrations in the spent brine (300 mg/L, 605 mg/L, 305 mg/L, and 24 g/L, respectively) were orders of ...

  • Hilltown Township, Pennsylvania Solves Arsenic, Iron and Manganese Problems with One System

    Hilltown Township, Pennsylvania, lies in the western corner of historic Bucks County. Located about 35 miles north of Philadelphia, the Township is home to the rolling farmland and 200-year-old farmhouses that are so common in this part of the state. The nearby Pearl S. Buck House, a National Historic Landmark housed in the nearly 200-year-old farmhouse that was Buck’s home for 38 years, pays ...

  • San Joaquin Valley California - Arsenic removal from ground water

    Background The San Joaquin Valley of California is approximately 220 miles long and varies in width to a maximum distance of approximately 80 miles. The occurrence of groundwater over the entire extent of the valley is abundant. Recharge for the varied depths of aquifers is from precipitation in the form of rain and the snow pack from the western Sierra Nevada Mountain Range. High ...

  • Inequitable allocation of deep community wells for reducing arsenic exposure in Bangladesh

    Community wells that extend deeper than most private wells are crucial for reducing exposure to groundwater arsenic (As) in rural Bangladesh. This study evaluates the impact on access to safe drinking water of 915 such intermediate (90–150 m) and deep (>150 m) wells across a 180 km2 area where a total of 48,790 tubewells were tested with field kits in 2012–13. Half the shallow private wells ...

  • 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. Above 12 mg C/L inorganic carbon concentration, the adverse effect of bicarbonate was definite, and resulted in higher remaining arsenic concentration. At all pH values (7.5–7.8) and coagulant dosages (0.84–3.00 ...

  • Distribution of arsenic and other minerals in rice plants affected by natural straighthead

    Because of the inconsistency and unpredictability of naturally occurring straighthead, arsenical herbicides are sometimes used to induce straighthead-like symptoms to study this sterility disorder. In 2005, an outbreak of naturally occurring (nonchemically induced) straighthead in rice (Oryza sativa L.) study fields in Stuttgart, AR provided an opportunity to examine the role of minerals in this ...
