A remote municipality’s existing system was failing, so the community needed an urgent replacement solution. Wembley is a quiet, peaceful northern Alberta town located 20 km west of Grande Prairie and surrounded by rich farmland. When the town installed a well to supplement the drinking water supply for its 1,400 residents, it learned the new supply source was unusable due to its high iron ...
The importance of soil cannot be overstated. It’s the basis of agriculture, and as a result, is a critical component of sustaining human life. According to the EPA: “Productive soils, a favorable climate, and clean and abundant water resources are all essential for growing crops, raising livestock, and for ecosystems to continue to provide the critical provisioning services that ...
The goals of the ERH remediation system were to achieve analyte-specific cleanup goals for PCE andTCE in the upper clay layer and for PCE, TCE, cis-l,2-DCE, 1,1-DCE, 1,1-DCA and vinyl chloride in shallow groundwater. The system incorporated 91 electrodes with co-located vapor recovery (VR) wells to treat a soil volume of approximately 20,800 ...
Algal biofuels around the world represent a sustainable pathway to meet increasing demand for fuel and clean energy with reduced environmental impact. More than half of that mass consists of lipids or triacylglycerides which are also found in vegetable oils and are used to produce such advanced biofuels as biodiesel, green diesel, green gasoline and green jet fuel. Algal remediation technology ...
The efficiency of Moringa (Moringa oleifera Lam.) seeds for removing lead ions (Pb2+) from water was evaluated. Parameters such as solution pH, adsorbent mass, contact time between solution and adsorbent, isotherms, thermodynamic, kinetics, and desorption were evaluated. The maximum adsorption capacity of the biosorbent was found to be 12.24 mg g−1. In order to verify the ...
In situ chemical immobilization is a practical remediation technology for metal-contaminated soils because of its capability to reduce cost and environmental impacts. We assessed the immobilization effects of poultry waste amendment and plant growth (Panicum maximum Jacq.) on Pb speciation and enzyme activities in shooting range soils. Soil contaminated with Pb was obtained from the top 20 cm of ...
