Although many people confuse the terms remediation and restoration, they are two separate processes in the restoration of impaired ecosystems. A special series in the April 2016 issue of IEAM challenges practitioners and researchers to rethink the traditional linear, sequential process of ecological restoration, instead encouraging a collaborative approach along the way, to integrate restoration goals throughout the process, beginning with site assessment. Guest Editors Aida Farag and Ruth Hull discuss workshop findings and tell us why we should heed an ounce of prevention when restoring ecosystems. Access the series in the April 2016 issue of IEAM.
The largest coal fly ash spill in US history occurred in 2008, at the Kingston Fossil Plant in Roane County, Tennessee. Over 4.1 million cubic meters of toxic coal fly ash spilled into the surrounding river ecosystem, which included three rivers and a reservoir. The January 2015 issue of IEAM features a special series of articles that detail the Baseline Ecological Risk Assessment (BERA) conducted to assess residual ash remaining in the Watts Bar Reservoir.
California recently adopted an innovative framework for assessing sediment quality impacts to the benthic community based upon multiple lines of evidence. The seven articles in the series address one aspect of a multi-phase project to define sediment quality objectives, including a new sediment quality guideline (SQG) index.Steve Bay, Guest Editor of the special series “California Sediment Quality Objectives,” describes how the series articles define sediment quality objectives for California that will be used to protect fish, wildlife, benthic invertebrates, and even humans. Access the series in the October 2012 issue of IEAM.
Todd Bridges addresses the process of managing and remediating contaminated sediment in the United States. There are currently more than 300 sites in the US federal government’s program to clean up the nation’s uncontrolled hazardous waste sites (Superfund). Hear Todd discuss proposed actions to accelerate cleanup progress and improve the effectiveness of risk management. Read the article “Accelerating progress at contaminated sediment sites: Moving from guidance to practice,” in the April 2012 issue of IEAM.
Julann Spromberg and Nat Scholz talk about the phenomenon of pre-spawn mortality in coho salmon in the Pacific Northwest. Their paper “Estimating the future decline of wild coho salmon populations resulting from early spawner die-offs in urbanizing watersheds of the Pacific Northwest, USA” is published in the October 2011 issue of IEAM.
Igor Linkov and Brad Sample talk about the July 2011 series “Challenges Posed by Radiation and Radionuclide Releases to the Environment”—16 invited commentaries that were solicited as a result of the Fukushima Daiichi nuclear accident in Japan that occurred in March 2011. The commentaries address various aspects of radiation concerns.
