Bioremediation Project

Prob Scenario and Specifications

Due to the the growing number of agricultural areas around the United States, these farms across the country have had an increasingly large impact on local runoff. The high concentration of phosphates and nitrates in the many water systems such as the rivers, streams, and ponds have caused many environmental problems. Different algae in affected water systems utilize the excess phosphate to spur population growth. With more algae in the water, less oxygen is available to marine life, such as fish and insects. Without a sufficient amount of oxygen in the water, marine life in the body

The natural organisms break down the hurtful material into non toxic substances or at least into less toxic substances. Bioremediation may need something to help boost the growth of the helpful eating organisms and can receive this help by oxygen and fertilizers, but it may also do it on its own. This is an open option for the destruction of these harmful contaminants with natural activity. Along with the greatness of the natural ways it is also low on the pricing scale along with the technology scaling. However along with the greatness of low pricing comes some cons, there is a long time frame associated with this along with the effectiveness of the amount of contaminants. Bioremediation has been used numerous times worldwide with different varieties of success. The knowledge and success has only grown as the time and experience has grown. Bioremediation will do tremendous amounts in dealing with contaminants. The only obstacle in the way would be the lack of knowledge in the principles, techniques, along with the advantages and disadvantages of the project

Before that there was a technique in which they would scoop up the contaminants and move them elsewhere. Obviously we have ran out of elsewheres and there is a risk of excavation, handling and moving this material. Those are just the beginning of the wrongs in that technique. There is so much more to do when it is handled this way such as the monitoring needed to maintain the isolation and barriers for the future. In a reality check it is obvious that the harmful organisms should just be taken care of and destroyed. Pseudomonas putida is a bacteria in which made bioremediation a necessity, which is the first image pictured. Along with biocarbon clastic, this is the second picture presented. The third is a picture of the bacteria geobacter sulfurreducens, this is used in helping the groundwater contamination and soil.
