  • Arsenic Exposure and Childhood CancerA Systematic Review of the Literature

    The literature on environmental arsenic exposure and childhood cancer risk comprises 1) studies seeking childhood cancers among arsenic-exposed populations, 2) studies seeking arsenic exposure among childhood cancer cases, and 3) studies seeking associations in populations with both arsenic exposures and childhood cancer cases. No skin cancers were found in dermal examinations of over 25,000 ...

  • Lummi Island, Washington - Arsenic, Iron, Sulfide Treatment System

    In mid 2004, AdEdge Technologies Inc. (AdEdge) was selected by Miller Water Association and Anvil Corporation to assist in the design of a fullscale arsenic treatment project for this small community. Arsenic levels are alarmingly high at 0.18 mg/l, 18 times higher than the new Federal standard of 0.010 mg/l. In addition to arsenic, many of the homeowners using the water objected to the sulfide ...

  • Arsenic-induced skin conditions identified in southwest dermatology practices: an epidemiologic tool?

    Populations living in the Southwest United States are more likely to be exposed to elevated drinking water arsenic levels compared to other areas of the country. Skin changes, including hyperpigmentation and generalized hyperkeratosis, are the most common signs of chronic arsenic ingestion from drinking water. The purpose of this study was to determine the feasibility of using dermatology ...

  • Efficacy of arsenic filtration by Kanchan Arsenic Filter in Nepal

    Groundwater arsenic contamination has caused a significant public health burden in lowland regions of Nepal. For arsenic mitigation purposes, the Kanchan Arsenic Filter (KAF) was developed and validated for use in 2003 after pilot studies showed its effectiveness in removing arsenic. However, its efficacy in field conditions operating for a long period has been scarcely observed. In this study, ...

  • Adsorption mechanism of As(V) and As(III) on Fe–Mn binary oxides in synthetic and real water matrices

    A series of Fe–Mn binary oxides with different Fe:Mn ratios (1:1, 3:1, 6:1, 9:1) were synthesized to investigate the optimal Fe:Mn ratio for the removal of As(III) and As(V). Batch experiments were performed to determine the rate of adsorption and equilibrium isotherms. Adsorption kinetics were well described by the pseudo-second-order kinetic model for both As(III) and As(V). The adsorption ...

AdEdge was selected from the proposed alternatives by the host site and ...

  • Profile: Kilogram-scale synthesis of iron oxy-hydroxides with improved arsenic removal capacity: Study of Fe(II) oxidationâprecipitation parameters

    This work describes a thorough research of the iron oxy-hydroxides’ preparation using the most common low cost iron salts (FeSO4•H2O and FeCl2) and their evaluation as As(III) and As(V) adsorbents. It is the first study that summarizes the role of synthesis parameters on the arsenic adsorption efficiency of iron oxy-hydroxides under the perspective of large-scale production and ...

  • The effectiveness of arsenic remediation from groundwater in a private home

    Abstract Private wells are the source of drinking water for approximately 15% of households in the United States, but these wells are not regulated or monitored by government agencies. The well waters can contain arsenic, a known carcinogen that occurs in groundwater throughout the nation at concentrations that can exceed the Maximum Contaminant Level defined by the U.S. Environmental ...

  • EPA Arsenic Treatment Demonstration - Rollinsford, New Hampshire

    In mid 2003, AdEdge was awarded 3 Arsenic Treatment Demonstration Projects with EPA. Implementation began in September, 2003 following approvals of the engineering submittals and permit by the New Hampshire Department of Environmental Services. Upon completion of construction of the new treatment building by the city of Rollinsford, AdEdge Technologies installed the 100 gpm APU arsenic treatment ...

  • 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 ...

  • 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 ...

  • Middle Verde, Arizona - Case Study

    AdEdge Water Technologies was contacted by Indian Health Services in August 2009 to design, manufacture, and start up an arsenic removal system for the Middle Verde community in Arizona. Middle Verde had an arsenic concentration of 0.02 mg/L, well above the United States Environmental Protection Agencys maximum contaminant level of 0.01 mg/L. The AdEdge treatment system consisted of an adsorption ...

  • Arsenic contamination in water: a conceptual framework of policy options with particular reference to Bengal delta basin

    Arsenic contamination in water supplies continues to increase in many countries, especially in developing nations, thereby creating both environmental and health hazard. Its sources and effects are multiple and diffused in nature and it requires detailed assessment and policy. This paper discusses the global extent of the problem, its sources and effects and explores different policy options. ...
