Water Pollution: Its Impact on Earth

Cadence DeLaneyEarth Science 100 10.27.24

Hypothesis

Water pollution, in comparison to other forms of environmental destruction, has the most profound impact on the biosphere.

Definition

Water Pollution:

• "The release of substances into subsurface groundwater or into lakes, streams, rivers, estuaries, and oceans" (Nathanson, 2024).
• "Substances interfere with beneficial use of the water or with the natural functioning of ecosystems" (Nathanson, 2024).
• "Chemicals, trash, or microorganisms, water pollution may include the release of energy, in the form of radioactivity or heat, into bodies of water" (Nathanson, 2024).

Water Pollution's Impact on the Natural Processes of the Earth and its System

• "Water pollution kills. In fact, it caused 1.8 million deaths in 2015... Every year, unsafe water sickens about 1 billion people" (Denchak, 2023).
• "the proliferation of newly introduced nutrients stimulates plant and algae growth, which in turn reduces oxygen levels in the water" (Denchak, 2023).
• "Marine ecosystems are also threatened by marine debris, which can strangle, suffocate, and starve animals" (Denchak, 2023).

How is Water Pollution Impacted by Earthquakes?

Water Quality

• "serious impacts on water quality can occur when strong earthquake shaking damages sewer lines, gas lines, or any infrastructure containing hazardous materials, releasing contaminants into the water" (USGS, n.d.).
• "The impact of an earthquake on river water quality is massive, and the quality of life and environment typically changes as a result of a quick drop in the environment system" (Jafarpour et al., 2024).

Water Pollutions Effects on Earth's Hydrosystems

• "The earth's hydrological cycle links interactions between the atmosphere, lithosphere, biosphere and anthroposphere, and it is also profoundly affected by human activities and socio-economic development" (Singh, 2024).
• "effects of water pollution include disruption of aquatic ecosystems" (Singh, 2024).
• "Monitoring and managing water quality indicators, such as dissolved oxygen, biochemical oxygen demand (BOD), and chemical oxygen demand (COD), are essential to assess pollution levels and protect water resources" (Singh, 2024)

14. Conclusions

Long-Term Consequences to the Earth

2.

1.

Physical Impact on Marine Life

Chemical Impact

the buildup of persistent organic pollutants like PCBs and DDT (The Ocean Cleanup, n.d.)

"entanglement, ingestion, starvation" (The Ocean Cleanup, n.d.)

3.

4.

Migrational Impact

Economic impact

"Transport of invasive species and pollutants from polluted rivers to remote areas in the ocean" (The Ocean Cleanup, n.d.)

"Damage to fisheries, shipping, and tourism" (The Ocean Cleanup, n.d.)

Impacts on natural processes of Earth's oceans

"bioaccumulation of toxic substances, which not only affects plant health but also poses a threat to organisms further up the food chain that consume these contaminated plants"

"High levels of nitrates in water from nutrient pollution can also be particularly harmful to infants, interfering with their ability to deliver oxygen to tissues and potentially causing 'blue baby syndrome'"

"fuel algae blooms that then create dead zones, or low-oxygen areas where fish and other aquatic life can no longer thrive"

Animals

Plants

Humans

(Gallagher, n.d.)

(Nunez, 2010)

(Nunez, 2010)

Atmospheric Water Pollution

"Air pollution contributes to one in ten deaths globally" (Ritchie, Roser, 2017).

• "water particles mix with carbon dioxide sulphur dioxide and nitrogen oxides, forming a weak acid" (Ohm, 2018)
• "water vapour absorbs more of these gases and becomes even more acidic" (Ohm, 2018)

Viable Solutions

Chemical and Fuel Disposal

Vehicles

"Make sure to blow or sweep it back onto your grass if it gets onto paved areas, and avoid applying fertilizer on the grass right before it rains, so it doesn’t wash into storm drains and waterways" (Pace, 2023).

"Never flush pills, powders, or liquid medicines down the toilet or dump them outside, whether on land or water. These drugs can accumulate in the water and be consumed by fish and other wildlife" (Pace, 2023).

"Maintain your vehicle’s maintenance... to prevent oil and other fuels from leaking onto the road. Leaky seals, hoses, and gaskets often leak fluid from cars and end up in the local water table, or runoff into nearby streams, rivers, and other bodies of water" (Pace, 2023).

"Put used oil or antifreeze in a sturdy container and take it to a local service station or other approved center. Your community may have a recycling center that will accept the used motor oil and recycle it. Community collection centers and drop-off sites also exist in some areas" (Pace, 2023).

Pesticides, Herbicides, etc.

Medcial Waste

Proposed Solutions

I propose...

• Conscientious monitorization of pollution levels around large cities
• higher degrees of filtration in storm drains/sewage systems,
• more environmentally sound ways to dispose of trash and other pollutants.

Conclusion

Given the evidence provided (water pollution's effect on natural processes, hydrosystems, long term consequences, and even atmospheric water pollution)remains the most detrimental form of pollution to the entire biosphere.
