  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Park City, Utah Arsenic removal from ground water

    Background Park City Utah Water, which serves a population of 6,500, has five water sources. Spiro Tunnel and Spiro Portal are two that were in need of Iron and Manganese removal as well as above limits for Arsenic. Filtronics was engaged by the engineering firm of Eckhoff, Watson and Preator (EWP), Salt Lake City, to perform pilot tests for the Park City Municipal Corporation. The ...

  • Bacterial biofilms formed in arsenic-containing water: biodeterioration of water network materials

    The immersion of any material in a water system triggers a surface microbial colonization which simultaneously influences the corrosion behavior of the substratum. The present study was focused on the As(V) influence on the biofilm formation and their consequences on the corrosion behavior of different substrata. Commercial materials used in water distribution networks: alloys based on Fe, Zn ...

  • Human health risk assessment of an arsenic contaminated golf course

    St Michael’s Jubilee Golf Course in Widnes was constructed between 1964 and 1986, by re-grading chemical waste deposits generated from local industries, which were then covered with a thin layer of topsoil and grassed over.  An estimated 4.5 million tonnes of waste materials are present beneath the golf course.  The site is underlain by alluvium and a major aquifer, the Sherwood ...

  • 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 ...

  • State of the art treatment for Arsenic, color, and Hydrogen Sulfide - Case Study

    New Arsenic Regulations How meaningful to the average water customer are µg/l or parts per billion? Not very. How about the word “arsenic”? That will ring some bells as the mystery novel poison-of-choice. But with new, lower EPA arsenic standard of 10 ppb that went into effect Jan. 16, cities with ...

  • Project profile - Yucca Mountain project, Nevada arsenic treatment system

    Background Wells J-12 and J-13 are located in Area 25 of the Nevada Test Site near Mercury, Nevada. These wells supply potable water for the Yucca Mountain Project. Water-quality analyses revealed that arsenic concentrations exceeded the new maximum contaminant level (MCL). Before choosing a technology, the site manager, Bechtel SAIC, contracted with Dr. Dennis A. Clifford, ...

  • An assessment on Spirulina platensis as a biosorbent for arsenic removal

    A column consisting of algal biosorbents like agar-agar, alginic acid, calcium alginate and Spirulina platensis biomass entrapped in polyurethane foam matrix was designed and tested for the removal of As(V) from the aqueous medium. The performance of the column was studied in terms of removal efficiency, metal sequestered in the column during a specified time and biosorption capacity. The ...
