  • Warm Springs, GA Radium Removal - Case study

    The City of Warm Springs is a small community of approximately 500 residents located in central Georgia. In 2010, water testing found a radium level between 8 – 11 pCi/L and a Gross Alpha level of 25 pCi/L, both above state and USEPA drinking water regulations of 5 pCi/L and 15 pCi/L respectively. Engineering Management Inc (EMI) conducted a pilot test in late 2010 to test a manganese ...

  • The The `Design for Autonomous Net-Zero Water Buildings` Project Funded By NSF

    The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site.   The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water. The research team ...

  • Impact of European Water Framework Directive Article 7 on Drinking Water Directive compliance for pesticides: challenges of a prevention-led approach

    Article 7 of the European Water Framework Directive (WFD) promotes a prevention-led approach to European Drinking Water Directive (DWD) compliance for those parameters that derive from anthropogenic influences on raw water quality. However, the efficacy of pollution prevention interventions is currently uncertain and likely to be variable, which makes absolute compliance with the drinking water ...

  • Project profile - uranium treatment system Middletown Springs Elementary School Vermont

    Background The Middletown Springs Elementary School in Vermont is located in an area of the U.S. very susceptible to the formation of naturally-occurring uranium. Due to the high levels of uranium detected in the well water serving the School, it was placed on a “Do-not-Drink Advisory”. AdEdge was contacted by Otter Creek Engineering in June 2009 to assist the School in ...

  • Drinking Water Standards

    The most important point of departure for drinking water standards is the World Health Organisation Guidelines for Drinking Water Quality. These are widely used throughout the world with the exception of parts of North America. WHO’s Guidelines have evolved over a period of 50 years from standards to guidelines, reflecting the fact that they have no legal force. The WHO emphasises that it ...

  • Public health perspectives of channelized and unchannelized headwater streams in central Ohio: a case study

    Headwater streams constitute the majority of watersheds in the United States and many in the midwest have been channelized for agricultural drainage. Public health implications of water chemistry and aquatic insects within channelized and unchannelized headwater streams have not been explored. We sampled water chemistry and aquatic insects in two channelized and two unchannelized headwater ...

  • Guest editorial: the IRIS assessment of inorganic arsenic: is science being hijacked?

    The arsenic IRIS assessment exemplifies the current administration’s unwillingness to walk its own talk on transparency and scientific integrity. Early in her role as the EPA Administrator, Lisa P. Jackson expressed her now familiar mantra that regulatory initiatives must be “transparent” and risk assessments must be conducted to “ensure the highest levels of scientific ...

  • Removal of arsenic from an aqueous solution by pretreated waste tea fungal biomass

    Arsenic exists in natural waters both in inorganic and organic forms. The inorganic form of arsenic is more toxic compared to its organic form. Inorganic arsenic is the predominant form in contaminated groundwater. Arsenic exists in two,oxidation states: arsenite, As (III) and arsenate, As (V) (Pokhrel and Viraraghavan, 2006). It is introduced in the aqueous system through geochemical reactions ...

  • Reclaimed Water Disifection Alternatives to Avoid NDMA and THM Formation

    ABSTRACTThe Sanitation Districts of Los Angeles County (Districts) operate seven tertiary water reclamation plants (WRPs) with a combined treatment capacity over 200 million gallons per day (MGD). Chloramination is used at these WRPs for effluent disinfection. It was recently discovered that chloramination results in the formation of N-nitrosodimethylamine (NDMA), a compound with high ...

  • Wastewater Mining and Reuse: Creating Benign Future Scenarios

    Wastewater mining: In addition to being perhaps the most uninviting combination of words, it sounds like a most unlikely idea. But for almost 30 years, Aqueonics, now headquartered in Greenville, SC, has pioneered such systems, starting in the ’80s, with its first wastewater mining project. For that project, Aqueonics provided an onsite or decentralized treatment system for a developer in ...

  • Bench-scale testing of SW desalination using NF

    A majority of Southern California municipalities, including the City of Long Beach, depend on water purchased from the Metropolitan Water District of Southern California. However, due to over-allocation of the Colorado River, this water supply could potentially be restricted in the future. Consequently, the Long Beach Water Department (LBWD) is considering the construction of a 10 million gallon ...
