Bioremediation is a natural process of incorporating microorganisms to counteract and remove any harmful waste in polluted water, soil, or any other subsurface material. Enzymes or microorganisms start off by breaking down the floating contaminants into smaller pieces. As soon as they are broken down, the microbes consume the small contaminants as a source of food for energy. However, bioremediation requires precise environmental conditions in order to reproduce successful working microorganisms to target the waste within the community. (Figure A.1)
This process works in a manner of using fertilizer, temperature, and oxygen to successfully grow bacteria and fungi that will survive in a well-adapted living condition.This method is widely used in areas like oil spills because of its quick and easy process depending on a number of factors. Nonetheless, this innovative technique is essentially solving worldwide environmental problems as bioremediation is cost-effective and it only requires a minimal amount of energy to produce.

The microbes then filter out the contaminants in the polluted water by using them as a food source.
Once the microbes are grown, they will be transferred and introduced to contaminated sites.
HOW COULD BIOREMEDIATION AFFECT OUR EVERYDAY LIVES?
About 1.1 billion people from rural and urban communities of developing countries come face to face with life threatening waterborne diseases due to the poor water conditions. The waterborne diseases are caused by a variety of microorganisms and the exposure to untreated and hazardous water contaminations. Polluted water in places like Africa and India cause 1.4 million deaths per year. Infectious diseases like Dysentery and Cholera are common outbreaks because of the water containing deadly parasites and bacteria.
Climate change is also very likely to contribute towards an increase in diarrheal disease. Because waterborne diseases are often linked to a severe precipitation events like heavy rainfall or snowfall, people all over the world can be exposed to the outbreaks. The change in pH and nutrients can result in the degradation of freshwater that surrounds many communities.
Bioremediation offers numerous benefits for contaminated sites and towards many countries anywhere with its ability to put a stop in the growing water pollution rate. The form of bioremediation is sustainable, natural, and can be recycled back through the environment without any production of toxic waste.
