Types of Environmental Remediation

With an ever-growing population and advanced technological developments, there arises a need to address environmental pollution.

Environmental pollution can come from just about any source, including residential, commercial and industrial sites. From lawn pesticides to agricultural runoff, from used flashlight batteries to lithium batteries for an electric car, from wood smoke to nuclear power—these are all sources of pollution.

Remediation Technologies

Fortunately, as technology advances so do the means to clean up the environment. For example, nanotechnology is being utilized to treat water in a more effective and efficient manner than traditional treatment methods.

Water treatment is a critical area of interest as there is a need for clean, drinkable water. Methods of industrial wastewater treatment can include processes such as physical removal of contaminated soil, biochemical remediation and electrodialysis to separate contaminants based on their electrical charges.

Bioremediation is a popular method of environmental clean-up as it is non-toxic and relies on natural microorganisms to break down contaminants. Bioremediation is well-known for its use in cleaning up oil spills.

Natural Pollution

Not all forms of pollution are produced by human activities or industries. Dust storms in desert areas are a major source of air pollution, and when volcanoes erupt the air and water become contaminated with toxic gases and ash. These forms of pollution also have the potential to travel across the globe on air and ocean currents.

Salt contamination can be problematic in coastal areas. Saltwater intrusion from the sea can pose a serious threat to drinking water. While costly, desalination offers a solution that can provide water for irrigation or human consumption.

All of the comforts of the modern world, from heating and air conditioning to cell phones and computers, come with the by-product of environmental pollution. However, there are many effective methods to reduce pollution and clean it up if it enters the environment.
