Fruitvale water clean up is a serious project that needs fast action. Fruitvale’s town water supply is in danger of being contaminated. Years ago, containers of a bug pesticide called “No-Bug” were spilled onto the ground. How is this a problem? Well, Fruitvale’s soil is different than other cities, it has an ability to absorb the toxins that are found in No-Bug pesticide. These toxins soon end up in our groundwater and keep on traveling down hill. Fruitvale has about three years to clean up the chemicals, but how should we do it? Fruitvale’s solution is Bioremediation. What is bioremediation? Well, bioremediation is the use of living microorganisms to break down unsafe substances in the earth to safe substances. There are two different ways of carrying out bioremediation. One way is taking out all the hazardous material and injecting the microorganisms, not on the contaminated site. The second way has the microorganisms be put in the hazardous material on the contaminated site, and both are equally effective. Why should we choose bioremediation? …show more content…
Bioremediation has basically no effect afterward on the earth material. When the hazardous material is gone, so are the organisms. The microorganisms won’t survive after all the contaminate is broken down, just like a snail in a fish tank without algae. This makes it so there aren't any negative side effects to the treatment. A big plus to bioremediation is the cost. Bioremediation is only $200 - 400 thousand, an easily payable plan when compared to some of the others. Even with these big pros, there is still some negatives to
Mountaintop removal can impact the local water table, it contributes to an increase in the level of birth defects and it has destroyed over 1 million acres of land. Mountaintop removal changes the quality of the local ground water that is available to a community. This is often seen in the form of an increase or decrease in the amount of minerals that are present. In turn, this can also negatively impact local wildlife, eliminate fish species, and create less animal diversity. And when it comes to the level of birth defects, very few studies have pointed out this potential link, the changes in mineral content and atmospheric quality where a mountaintop coal mine is present could also be responsible for higher levels of birth defects. If true, then is the need for cheaper, cleaner coal worth harming children? It is sad that we are so dependent on coal mining for electricity. Coal mining is a nonrenewable resource that is outdated. It produces high levels of radiation, and the coal ash that is produced during the process is a hazard and there is no way to dispose of it
...kes a great argument showing us how the positive results outweigh the negative. Contamination isn’t so bad after all.
This is an important topic. It affects the overall health of the population surrounding the Chesapeake Bay, as we eat from it quite often and it can be used as a water source. The chemicals being released into the water are from coal-burning factories and runoff, which can be helped, but it’s almost impractical in this day and age to spend the amount of money required to do so without the technology that can guarantee a fix.
The word “remediate” means to solve a problem, so the word “bioremediation” refers to the use of biological organisms to solve an environmental problem. Bacteria, fungi, protists and other microorganisms in a non-polluted environment are constantly breaking down organic matter, and when the soil is polluted, some of the organisms may die, but others will still be able to break down the pollutants. Bioremediation provides organisms that can consume the pollutants with fertilizer, oxygen, and other conditions to encourage the rapid growth of these organisms. They then would be able to break down the organic pollutants at a correspondingly faster rate. There are two general ways in which bioremediation functions. One way is where specific survival conditions of a microorganism living in the soil are enhanced to increase the rate of a pollutant’s degradation. The second way is when specialized microbes are added to degrade the contaminant. This way is less common. For many types of polluted soil, bioremediation provides an excellent method of clean-up, but in some cases the pollutant is toxic even for the microbes. These pollutants include metals such as cadmium or lead, and salts such as sodium chloride. Although it may not work in all cases, bioremediation is considerably easier than other methods because it enhances the functions that the microbes already carry out in the soil. Along with being easier, it can be much less expensive because the soil does not have to be pumped out of the ground for treatment (Environmental Inquiry-Bioremediation). Serratia Marcescens is a bacterium that is commonly used for bioremediation.
According to Article 2, “Dilution is the Solution!” Applying a bucket of water to the contaminated area apparently does the job.
Not only does pollution destroy plants but it also affects the health of animals and humans. The affects of pollution on living organisms maybe short and long term. As a child growing I had a friend who was form India, and he would visit every few
Imagine a world where all of our fresh water was polluted to the point where we couldn’t drink it. That is exactly where we are heading if we do not fix this epidemic that is hitting, not only America, but Iowa in particular. It is apparent that Iowa’s water is posing health concerns such as polluting the water, creating dead zones in the Gulf of Mexico, and affecting the population’s drinking water.
... into fertilizer, this change also releases many harmful chemicals into the air, and once again the earth’s atmosphere is being destroyed.
Not mentioned in the report is a technique called bioremediation, which uses microbes to clean up the hazardous waste. Some small natural organisms, such as bacteria, can eat, digest and gain energy from contaminants, converting them into small amounts of water or innocuous gases. Specific conditions must be present for bioremediation to be successful. Natural amendments can be added if ideal conditions are not present, or contaminated soil can be treated ex situ. Traditionally, it takes anywhere between a few months and several years for bioremediation to fully clean a Superfund site, depending on the size of the site and extent of contamination. Bioremediation is currently being used to clean up contaminated groundwater at the Iceland Coin Laundry Superfund Site in New Jersey (EPA, n.d.). Additionally, experiments are currently underway to determine if fungi can help remediate some of the contamination at the Newtown Creek Superfund Site in New York City (Parry, 2012). As an all-natural alternative, bioremediation is a particularly appealing clean up method. If ideal conditions for microbial growth are not present at the Portland Harbor Superfund site, bioremediation could be a good ex situ treatment
For instance, in Seeds of Death, Monsanto spread roundup, a pesticide, on their crops and realized a roundup resistance bacteria continued to grow. In response to this, Monsanto collected the bacteria and took a piece of its DNA to create roundup resistant crops. Although this seems like a good idea, it makes crops weaker and makes it easier for crops to be wiped out by a stronger disease. In addition to this, the pesticides also pull nutrients from the soil, therefore resulting in the microorganisms in the soil being killed. This, in turn, leads to the soil being filled with poison and also being infertile in the near future. The worst part about these pesticides is that once it enters the environment, it’s in the environment
The bacteria and wastewater is mixed in an aeration tank and therefore the contaminants are removed by action of sorption and series of breakdown by the bacteria.
Reading up information and searching for clues (which were not extremely easy), turns out to have broadened my knowledge on Nature and Biomimicry itself and that there are so many people already using wind turbines to harvest the winds energy and know how the world can be saved. Therefore I have come to the conclusion and have seen that my hypothesis has been proven right.
Phytoremediation is characterized by the use of vegetative species for in situ treatment of land areas polluted by a variety of hazardous substances. (Sykes et al., 1999) Plants are especially useful in the process of bioremediation because they prevent erosion and leaching which can spread the toxic substances to surrounding areas. (United States Environmental Protection Agency, 2001) There are several types of phytoremediation being used today. These include phytoextraction, which relies upon a plant’s natural ability to take up certain substances (such as heavy metals) from the environment and sequester them in their c...
Traditional methods for cleaning up contaminated sites such as dig and haul, pump and treat, soil venting, air sparging and others are generally harmful to habitats. Some methods strip the soil of vital nutrients and microorganisms, so nothing can grow on the site, even if it has been decontaminated. Typically these mechanical methods are also very expensive. Most of the remediation technologies that are currently in use are very expensive, relatively inefficient and generate a lot of waste, to be disposed of.
Picking up litter whenever you find it is honestly the best, fastest way to stop this type of water pollution. While it may not sound extravagant, the act of not passing by this pollution is pretty powerful.
