    Course Reviews (4.7/5): 


    Summary: This practical course provides a comprehensive overview of stormwater pollutant control measures (i.e., best management practices - BMPs) and their performance. Topics include an overview of stormwater BMPs, BMP selection, performance assessment, BMP effectiveness, and performance optimization. The course focuses on how pollutant removal is affected by BMP design, operation, maintenance, and the use of treatment trains. Municipal, industrial, and construction BMPs are discussed. The latest BMP performance data from the International Stormwater BMP Database are presented. These data provide a baseline for understanding typical BMP performance and setting performance expectations. Recommended BMP inspection practices are also discussed.

      Course Reviews (4.8/5): 


      Summary: This course provides a comprehensive overview of the transport, fate, and attenuation of metals in soil and groundwater using the "Scenarios Approach". The Scenarios Approach was developed by Savannah River National Laboratory to provide a quick and easy framework for improving the assessment and remediation of inorganic contaminated sites. The Scenarios Approach is based on the interpretation of plume geochemistry, geochemical gradients, and specific inorganic contaminant behavior in various geochemical settings (e.g., Cr(VI) instability under low redox conditions). Understanding metal behavior within various geochemical conditions provides an improved method for predicting metal contaminant transport and fate, and implementing effective remediation strategies. The course focuses on metals in soil and groundwater, and is also applicable to sediment, stormwater, and surface water.

        Course Reviews (4.8/5): 


        Summary: This course provides a comprehensive overview of the transport, fate, and attenuation of metals in soil and groundwater using the "Scenarios Approach". The Scenarios Approach was developed by Savannah River National Laboratory to provide a quick and easy framework for improving the assessment and remediation of inorganic contaminated sites. The Scenarios Approach is based on the interpretation of plume geochemistry, geochemical gradients, and specific inorganic contaminant behavior in various geochemical settings (e.g., Cr(VI) instability under low redox conditions). Understanding metal behavior within various geochemical conditions provides an improved method for predicting metal contaminant transport and fate, and implementing effective remediation strategies. The course focuses on metals in soil and groundwater, and is also applicable to sediment, stormwater, and surface water.
