  • 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 ...

  • Spatial pattern of arsenic contamination in shallow wells of Bangladesh: regional geology and nonlinear dynamics

    Since the discovery of large-scale arsenic contamination of groundwater in Bangladesh more than a decade ago, studies related to its spatial characterization have relied on geostatistical approaches and the classical notion of linear stochastic dynamics. This study explores an alternative nonlinear approach, with a motivation to possibly achieve more cost-effective solutions for Bangladesh. It ...

  • Airport Lead and Arsenic Removal - Case Study

    City of Cincinnati The Airport was built on a former military firing range and apple orchard. To complete the removal of all the lead and arsenic, we excavated and removed over 20,000 tons of treated and non-treated contaminated soil. Then we stabilized 11,000 tons of hazardous soil on site. We graded and capped the site all while complying with FAA, City and Airport ...

  • Project profile - Bois Forte reservation palmquist site – Minnesota arsenic, iron, manganese treatment

    Background In May 2007, AdEdge Technologies, Inc. was selected by Indian Health Services to supply an arsenic, iron, and manganese treatment system for the Bois Forte Reservation – Palmquist Community Water System in Minnesota. The system has two wells that combine together to serve potable water to 50 connections in the tribal community. The system serves a population of ...

  • Effective Techniques for Arsenic Removal from Water

    Arsenic is a tricky substance because it is colorless and odorless, making detecting its presence and ensuring its removal at a contaminant site tricky. However, high levels of arsenic can have drastic, fatal effects on wildlife as well as humans if left untreated. If it isn’t properly and fully extracted, serious problems can result. If you’re considering the best industrial ...

  • City of Wellman, Texas - Arsenic Treatment System

    The City of Wellman, Texas (Wellman) applied to the U.S. Environmental Protection Agency (USEPA) to participate in the arsenic treatment demonstration program for Round 2 and was selected. Wellman has five water-supply wells which pump water to a 110,000 gallon storage tank. Water-quality analyses revealed that arsenic concentrations exceeded the new maximum contaminant level (MCL). AdEdge ...

  • Understanding the 3 Types of Arsenic Removal Used for Wastewater

    With the onset of the Industrial Revolution and the development of internal combustion engines and new manufacturing technologies, fresh water became an essential raw material not only for production, but for cooling purposes in manufacturing processes. However, when fresh water is used in an industrial process, it creates industrial wastewater composed of a variety of chemicals and other raw ...

  • Thermal Remediation of Karst Limestone – Redstone Arsenal, Alabama

    Abstract: Electrical resistance heating (ERH) was used for the thermal remediation of two sites at Redstone Arsenal (RSA) near Huntsville, Alabama. Both sites feature karst limestone with heavy clay overburden. The two sites are located about five miles (10 km) apart, but differ considerably in the characteristics of the limestone. At site RSA-053, the heavy clay is underlain by very hard, ...

  • Orchard Highlands - USEPA Arsenic Treatment Demonstration - Goffstown, New Hampshire

    In 2004 AdEdge Technologies Inc. (AdEdge) was selected to implement six fullscale arsenic treatment demonstration projects as part of the USEPA Office of Research and Development arsenic research program (Round 2). These six sites were in addition to three USEPA Round 1 demonstration sites awarded to AdEdge in 2003. The purpose of the research effort is to provide information to fill-in gaps that ...

  • Development of a portable filter for arsenic removal from drinking water

    In the present study, different grades of indigenously available activated alumina (AA) were screened for their arsenic removal capacity. For both As(III) and As(V), A1 (Grade 1, 0.3-0.6 mm) activated alumina has shown better removal efficiency. The optimum pH for the adsorption phenomena was around 7.0. Chlorine at a dose of 20 mg/l could completely oxidize As(III) to As(V), which also assured ...

Before choosing a technology, the site manager, Bechtel SAIC, contracted with Dr. Dennis A. Clifford, ...

  • Evaluation of biofilter performance to remove dissolved arsenic: Wood Cadillac

    The Wood Cadillac mining site, in north-western Quebec, is an important source of arsenic contamination. The arsenic-rich effluent is treated through a reductive biofilter, which allows arsenic to precipitate as a sulphide (likely As2S3). The top-fed biofilter, built at the end of 1999, is 50 m x 57 m by 1 m thick. The reducing conditions are provided by the decomposition of yellow birch bark ...
