Enviromantal engneering project - Essay Example rmore, instead of excavating and transferring the contaminated soil to another site, this process proved successful as it was done on site- saving time and energy. Bioremediation- According to Prof. Shaily Mohindra of UCLA, conventional technologies for cleaning ground water are not always effective. Moreover, these methods usually move pollutants from one point to another. For that reason, Mohindra endorses Bioremediation using Pseudonocardia dioxanivorans bacteria for the mitigation of next generation pollutants e.g. Perfluorinated compounds, nano materials, and dioxane. The progress of remediation will be monitored usin stable isotopes. Pump and treat- The application of pump and treat technology in Hanford has been successful in soil and ground water remediation. By 2011, 24.7 billion gallons of ground water had been treated, although the whole process of remediation will be completed in the next 25 years. At the end of the remediation process Contaminants such as plutonium and i ts derivatives e.g. Carbon tetrachloride will be successfully removed from the soil and ground water. In situ thermal remediation- pump and treat technology had been used for more than 17years to clean up chlorinated solvents from the subsoil in Stuttgart with minimal success rates. However, in January 2013 an in-situ thermal remediation pilot test offered a suitable alternative for remediation even under prevailing difficult geological conditions in Stuttgart. Monitored natural attenuation- The Company was justified as it relied on natural processes to clean up the site. An environmental disaster similar to the silent spring has also been observed in Oregon (Lower Columbia). Since 1985, conservation centered on removing the nearly extinct bald eagle from the federal extinction list resulted in significant overall increase in bald eagle numbers. Yet, in lower Columbia most of the eagle nests in the lower Columbia failed to hatch eaglets; and have been producing half the number of
