  • 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 ...

  • Arsenic Removal

    The Arsenic Removal ProcessArsenic, a naturally occurring element, is found throughout the environment; for most people, food is the major source of exposure. Acute (short-term) high-level inhalation exposure to arsenic dust or fumes has resulted in gastrointestinal effects (nausea, diarrhea, abdominal pain); central and peripheral nervous system disorders have occurred in workers acutely ...


  • 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 in Bangladesh and Perth

    This study details the the Arsenic problem in ground water from Bangladesh and how the PDV6000plus can be used to monitor the Arsenic levels in ground water wells. Contains comparison data with inductively coupled plasma mass spectrometer (ICPMS) for groundwater samples in Perth, Western ...

  • Arsenic Treatment-Michigan

    In May, 2003, upon approval by the County Health Department, Adedge Technologies in conjunction with its Michigan representative Artesian, Inc. installed the first arsenic treatment system for a Type II non-transient, noncommunity (NTNC) water system in Oakland County, Michigan. The 40 gallon per minute (gpm) system was installed at an elementary school serving 600 students to reduce naturally ...

  • Groundwater arsenic in Chimaltenango, Guatemala

    In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site ...

  • EPA Arsenic - Demonstration Projects

    AdEdge Technologies, Inc. was selected by USEPA through an expert peer review process in cooperation with the individual host sites to conduct full scale arsenic treatment demonstrations using its Granular Ferrric Oxide Adsorption Technology. The program is designed to gather further cost and performance data on commercially available, proven technologies which are candidates to become Best ...

  • Arsenic in private drinking water wells: an assessment of jurisdictional regulations and guidelines for risk remediation in North America

    Arsenic is a known carcinogen found globally in groundwater supplies due to natural geological occurrence. Levels exceeding the internationally recognized safe drinking water standard of 10 μg/L have been found in private drinking water supplies in many parts of Canada and the United States. Emerging epidemiological evidence confirms groundwater arsenic to be a significant health concern, ...

  • USEPA Arsenic Demonstration Project - Stewart, Minnesota - Arsenic and Iron Treatment System

    AdEdge Technologies Inc. (AdEdge) was selected in 2004 by the U.S. EPA as part of the Round 2 Arsenic Demonstration Program to implement full scale arsenic treatment for the city of Stewart, Minnesota. This public water system serves a community of approximately 600 people with average daily demand of 60,000 gallons per day. AdEdge was selected from the proposed alternatives by the host site and ...

  • Project profile - arsenic treatment-Michigan

    Background In May, 2003, upon approval by the County Health Department, Adedge Technologies installed the first arsenic treatment system for a Type II nontransient, non-community (NTNC) water system in Oakland County, Michigan. The 40 gallon per minute (gpm) modular system was installed at an elementary school serving 600 students to reduce naturally occurring arsenic to meet the new EPA ...

  • Arsenic and Bladder Cancer: Observations and Suggestions

    Arsenic from drinking water is a well-known risk factor for bladder cancer. The purpose of this paper is to systematize some important yet often overlooked facts considering the relationship between arsenic exposure and the occurrence of bladder cancer. Since the exposure to inorganic arsenic from food, inhaled air, and skin absorption as well as arsenic methylation ability are not fully ...

  • 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 ...

  • Optimisation of sugar cane activated carbon for arsenic(V) and arsenic(III) removal from water

    This paper addresses the development of low-cost adsorbents for removal of arsenic from water in support of mitigation programmes in low and middle income countries. Activated carbon (AC) is a well established water treatment technology, but has high cost and low selectivity in respect of arsenic. AC made from agricultural by-products is a low-cost alternative to coal-based AC. In this study, ...

  • Dynamic factor analysis for estimating ground water arsenic trends

    Received for publication March 14, 2009. Drinking ground water containing high arsenic (As) concentrations has been associated with blackfoot disease and the occurrence of cancer along the southwestern coast of Taiwan. As a result, 28 ground water observation wells were installed to monitor the ground water quality in this area. Dynamic factor analysis (DFA) is used to identify common trends that ...

  • Treatment and remediation methods for arsenic removal from the ground water

    Globally, ground water is contaminating by arsenic continously, which needs economic treatment and remediation technologies. Physical, chemical and biological treatment methods have been developed, that include different kinds of filters, bucket type units, fill and draw, kalshi etc. The remediation methods discussed are air oxidation, reactive barriers, utilisation of deeper aquifers and ...

  • One process removes arsenic & iron from water in small Utah town

    The Safe Drinking Water Act brought with it tough arsenic compliance standards, forcing cities large and small to comply with a maximum contaminant level of 10 parts per billion (ppb) or face stiff fines and even the potential shutdown of wells. Smaller towns such as Cannonville, Utah, face the most difficult challenge, due to manpower and budget constraints. Cannonville turned to Filtronics, ...
