  • DBP reduction using mixed oxidants generated on site

    The Safe Drinking Water Act (SDWA) was established by the US Environmental Protection Agency (USEPA) in 1974 to protect the quality of the nation’s drinking water. Although the use of disinfectants in drinking water has drastically reduced disease, these disinfectants can react with material in the raw water and form disinfection by-products (DBPs) that are also hazardous to health. Initially, ...

  • Risk-based planning for water recycling in an Australian context

    Australia has seen an unprecedented proliferation in large scale water recycling schemes since the late 1990s. This has been driven by a recent decade of drought, policies to encourage water efficiency in new homes and buildings in urban areas, and to reduce pressure on rain-fed water supplies by replacement with alternate water sources in rural areas. Underpinning these drivers are principles ...

  • Ecological risk assessment in the context of global climate change

    Changes to sources, stressors, habitats, and geographic ranges; toxicological effects; end points; and uncertainty estimation require significant changes in the implementation of ecological risk assessment (ERA). Because of the lack of analog systems and circumstances in historically studied sites, there is a likelihood of type III error. As a first step, the authors propose a decision key to ...

  • Non-intrusive site investigation (UXO, CWM concerns)

    BEACON personnel used global positioning system (GPS) equipment to map out site locations. The soil-gas data clearly identified source areas of Trichloroethene (TCE) as well as other compounds of concern. The results showed the location of chlorinated contamination, which correlated well with data from a geophysical survey. While the flux chambers were in the field, more than nine inches of rain ...

  • Environmental Insurance: Finding a Good Tailor
