There are four main types of air pollution sources: mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces.

Microorganisms help in cleaning up the environment. They decompose dead and decaying matter from plants and animals, convert them into simpler substances which are later used up by other plants and animals. Thus, they are used to breakdown harmful substances.

Bioremediation offers numerous advantages over other cleanup methods. By relying solely on natural processes, it minimizes damage to ecosystems. Bioremediation often takes place underground, where amendments and microbes can be pumped in order to clean up contaminants in groundwater and soil.

The bioremediation process is a biological process that stimulates helpful microbes to use harmful contaminants as their source of food and energy. Here, human intervention can speed up the natural remediation by boosting microbial action.

Phytoremediation

A number of methods such as coagulation, filtration with coagulation, precipitation, ozonation, adsorption, ion exchange, reverse osmosis and advanced oxidation processes have been used for the removal of organic pollutants from polluted water and wastewater.

6 Proven Environmental Cleanup Methods

1. 1.) Ground Water Pumping and Treatment:
2. 2.) Waste Water Treatment:
3. 3.) Bio-remediation:
4. 4.) Incineration:
5. 5.) Thermal Desorption:
6. 6.) Removal and Disposal:

Simply saving energy is the most cost-effective way to reduce demand and carbon pollution from power plants. The cheapest, cleanest and most reliable electricity, after all, is the electricity we don’t use.

It is estimated that cleanup costs for a medium-large oil spill could be between $2.4 billion and $9.4 billion dollars. Cleanup costs for an oil spill could be between $2.4 billion and $9.4 billion dollars.

When oils rigs or machinery malfunction or break, thousands of tons of oil can seep into the environment. Oil spill effects on environments and habitats can be catastrophic: they can kill plants and animals, disturb salinity/pH levels, pollute air/water and more.

Oil spills are harmful to marine birds and mammals as well as fish and shellfish. Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water repellency of a bird’s feathers, thus exposing these creatures to the harsh elements.

Thousands of oil spills occur in U.S. waters each year, but most are small in size, spilling less than one barrel of oil. Yet since the iconic 1969 oil well blowout in Santa Barbara, California, there have been at least 44 oil spills, each over 10,000 barrels (420,000 gallons), affecting U.S. waters.

Q: Where do most oil spills happen in the world?

• Gulf of Mexico (267 spills)
• Northeastern U.S. (140 spills)
• Mediterranean Sea (127 spills)
• Persian Gulf (108 spills)
• North Sea (75 spills)
• Japan (60 spills)
• Baltic Sea (52 spills)
• United Kingdom and English Channel (49 spills)

There were an average of 1.8 large oil spills from tanker incidents every year in the decade from 2010 to 2019. So far for 2020, there have been no noted oil spills were more than 700 metric tons of oil was leaked. In the years since the 1970’s the number of oil tanker spills has been notably reduced.

Dispersants and booms and skimmers are the most frequently used methods to clean up ocean oil spills. All methods have advantages and disadvantages. The effectiveness depends on the situation – the amount and type of oil, the ocean currents and tides and the weather. Some methods can be harmful to the environment.

Oil spills are rare and getting rarer — but any risk is too much for some.

Oil spills that happen in rivers, bays and the ocean most often are caused by accidents involving tankers, barges, pipelines, refineries, drilling rigs and storage facilities, but also occur from recreational boats and in marinas. Spills can be caused by: people making mistakes or being careless.

Oil spills are some of the most familiar man-made disasters, devastating to people, the environment, animals and global socioeconomics. 2010 saw the worst and largest oil spill: the Deepwater Horizon Oil Spill in the Gulf of Mexico. Besides the Deepwater spill, there have been 44 other oil spills globally since 1969.

Since 2011, Shell has reported 1,010 spills, with 110,535 barrels or 17.5 million litres lost. That’s about seven Olympic swimming pools. These are huge numbers, but the reality may be even worse.
