Application of Site-Screening Tools to Evaluate Ecological Effects from Trace Organics
New WERF research is helping to refine site-screening tools so that water quality managers will be better equipped to evaluate the potential for adverse effects from exposure to trace organic compounds, which can be present in treated wastewater and receiving waters.
NEBRA Launches Biogas Website
The North East Biosolids and Residuals Association (NEBRA) unveiled a new website that provides updated data on anaerobic digestion and biogas production at wastewater treatment facilities across the United States. The website, www.biogasdata.org, provides policy-makers, market analysts, project developers, and water quality professionals with key information about the potential for biogas production as a renewable fuel.
WERF Recognizes San Antonio Water System for Achieving a Clean Water Trifecta
WERF recognized San Antonio Water System with its Award for Excellence in Innovation for achieving its goal to recycle and use all treatment process residuals. San Antonio’s motivation to achieve that goal grew from their conviction that wastewater treatment process residuals are valuable resources to be beneficially used, not waste products for disposal.
Risk Management and Trace Organic Compounds in Land-Applied Biosolids Update
Risk assessments are needed to determine whether there is any significance in the levels of trace organic compounds found in biosolids-amended soils. WERF has developed a significant first step toward answering this question.
