The Honourable Tim Uppal, Minister of State (Multiculturalism) and Member of Parliament for Edmonton-Sherwood Park, on behalf of the Honourable Greg Rickford, Canada's Minister of Natural Resources and Minister for the Federal Economic Development Initiative for Northern Ontario, announced an investment of $1 million under Canada's ecoENERGY Innovation Initiative (eco
Stormwater treatment area in the Everglades Agricultural Area (EAA) which is one of several designed to remove phosphorus from urban and agricultural runoff. These public works projects are the second point of cleanup for the water, while the farmers are the first point.
The announcement follows an investigation by the National Audit Office (NAO) of more than a dozen engineering and applied-research ‘megaprojects'. Together, the projects receive a whopping $8 billion a year in funding.
Arsenic, a well-known poison, can be taken out of drinking water using sophisticated treatment methods. But in places that lack the equipment or technical know-how required to remove it, it still laces drinking water and makes people sick.
University of Cincinnati research project is taking a groundbreaking approach to monitoring groundwater resources near fracking sites in Ohio. Claire Botner, a UC graduate student in geology, will outline the project at The Geological Society of America's Annual Meeting & Exposition.
This report explores methods and costs of remediation of groundwater nitrate contamination in the Tulare Lake Basin and Salinas Valley. Groundwater cleanup, or remediation, is one of the most difficult actions in the environmental sciences, even when done on the scale of a small contaminant plume (1000s of cubic meters). Remediation of entire groundwater basins has never been attempted at the scale and depths of the Salinas Valley and Tulare Lake Basin, on the order of billions of cubic meters. This analysis shows that direct remediation to remove nitrate from large groundwater basins is extremely costly and not technically feasible. In situ remediation, though technologically infeasible as a regional remedy, is appropriate in certain areas of shallow groundwater with high contaminant levels.
Traditional pump and treat (ex situ) methods are too slow to produce results on the regional scale in an
acceptable time frame, prohibitively expensive, and impractical to implement.
This TECDOC focuses on the technical options for remediation of radioactively contaminated groundwaters, as well as on the planning and management options to accomplish environmental restoration of this valued resource. Most of the described technologies are applicable for the remediation of radioactive contaminated groundwater as well as for
remediation of non radioactive contaminated groundwater. As used here, the term "remediation" includes decontamination of groundwater and other media, stabilization or isolation of contamination, together with the disposition of wastes arising from the cleanup.
