Before you take another sip of your water supply, consider ...

  • Biological Filtration: Future of Drinking Water Treatment

    Water is essential for all human life on the planet, but the fresh water supply is limited and is susceptible to being contaminated by all manner of toxins like arsenic, calcium, and mercury. There are many techniques to remove contaminants, including popular methods that add chemicals to balance others out, but one that not many people understand is biological water system filtration. ...

  • 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, ...

  • 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 ...

  • 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 ...

Area 4 at the Raritan Arsenal was formerly used as a high explosives salvage and melt-out area from World War I ...


  • 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.

  • 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 ...

  • Treatment of Arsenic Contaminated Industrial Wastewaters

    Arsenic in industrial wastewater effluents is attracting greater regulatory attention. Depending on factors such as total maximum daily loads (TMDLs), the National Pollutant Discharge Elimination System (NPDES) discharge permit levels for arsenic may even be less than the drinking water standard of 10 µg/L. One of the industries affected by stringent arsenic discharge limits is coal-fired power ...

  • Executive Summary of Arsenic Contamination in the World
