Technology's Impact On Water Pollution: A Complex Relationship

Technology has had a profound impact on the environment, and water pollution is no exception. While technology has enabled us to address some environmental issues, it has also contributed to and exacerbated others. The production and use of technology can cause air, water, heat, and noise pollution, and the disposal of electronic waste can contaminate water sources. The development of shipping technology, for instance, has led to the introduction of invasive species, hazardous chemicals, and the discharge of ballast water, all of which contribute to water pollution. However, advancements in shipping technology, such as ballast-free systems and anti-fouling hull paint, are now being used to mitigate these issues.

Water pollution from electronic waste

Electronic waste, or e-waste, is a growing problem that poses serious threats to public health and ecosystems. E-waste contains toxic substances such as lead, mercury, cadmium, and lithium, which can cause neurological damage, increase the risk of chronic diseases and cancers, and lead to birth defects. When e-waste is improperly disposed of in landfills or other non-dumping sites, these toxins are released into the environment, impacting the air, soil, and water.

The improper disposal of e-waste can have detrimental effects on water bodies. Heavy metals from e-waste, such as mercury, lithium, lead, and barium, can leak into the groundwater and eventually make their way into ponds, streams, rivers, and lakes. This can lead to acidification and toxification of the water, which is unsafe for animals, plants, and communities, even if they are far from the recycling site. Clean drinking water can become difficult to find. Acidification can also kill marine and freshwater organisms, disturb biodiversity, and harm ecosystems, sometimes to the point of no recovery.

The burning of e-waste, often used to extract valuable metals, releases fine particles and fumes that can travel long distances, creating negative health risks for humans and animals. This can also result in air pollution, which, over time, can hurt water quality. An example of this is seen in Guiyu, China, where an informal recycling hub caused by the interest in extracting valuable metals from e-waste has led to extremely high lead levels in the air. This, in turn, affects the water and soil, causing neurological damage to larger animals, wildlife, and humans in the area.

The dumping of e-waste in regular landfills or illegal dumping sites can also lead to the seepage of heavy metals and flame retardants directly into the soil, contaminating the underlying groundwater and nearby crops. This contamination can cause various illnesses and reduce the productivity of farmland.

To mitigate the harmful effects of e-waste on water bodies, it is crucial to spread awareness about proper e-waste disposal and recycling. Consumers should be educated on the correct measures of disposal, and retailers should offer trade-in programs or incentives for people looking to upgrade their electronics. Additionally, when a product is totally unusable or broken, it must be disposed of by a certified e-waste hauler or recycler or taken to a designated drop-off location, as e-waste can cause harm to humans, animals, and the environment if not handled properly.

Water pollution from industrial processes

Industrial processes can generate a variety of waste, including cafeteria garbage, dirt and gravel, masonry and concrete, scrap metals, trash, oil, solvents, chemicals, weed grass and trees, and wood and scrap lumber. This waste can be solid, liquid, or gases held in containers, and it can be hazardous or non-hazardous. Hazardous waste may result from manufacturing or other industrial processes, and it can be toxic, ignitable, corrosive, or reactive. Certain commercial products, such as cleaning fluids, paints, or pesticides, can also be defined as hazardous waste if they are discarded by commercial establishments or individuals.

The improper management of industrial waste can have dangerous health and environmental consequences. For example, in the United States, the amount of hazardous waste generated by manufacturing industries increased from an estimated 4.5 million tons annually after World War II to approximately 265 million tons by 1990. This waste is generated at every stage of the production process, use, and disposal of manufactured products. The introduction of new products, such as computers, drugs, textiles, paints and dyes, and plastics, has also introduced hazardous waste into the environment.

Water pollution is one of the main consequences of industrial waste. Wastewater from manufacturing or chemical processes in industries contributes to water pollution, often in the form of toxic wastes and organic pollutants. This type of pollution is concentrated within a few subsectors, mainly the processing of industrial chemicals and the food products industry. Most major industries have treatment facilities for industrial effluents, but small-scale industries often cannot afford the necessary investments in pollution control equipment.

The effects of water pollution from industrial processes are devastating and far-reaching. Polluted water is unsuitable for drinking, recreation, agriculture, and industry. It diminishes the aesthetic quality of lakes and rivers, destroys aquatic life, and reduces its reproductive ability. Ultimately, it poses a hazard to human health, with high levels of toxic contaminants found in animals and humans, particularly those who are continually exposed to such waste streams.

To mitigate the impact of industrial processes on water pollution, it is essential to properly manage and treat industrial waste. This includes reducing or eliminating hazardous materials from the production process, using technology to make changes to the process, equipment, or operating conditions, and implementing waste minimization and recycling techniques. By taking these steps, we can work towards reducing the devastating effects of water pollution on our environment and health.

Water pollution from shipping

Shipping has a significant impact on the environment, including marine life, ocean habitats, and water bodies. The industry has turned to technology for more sustainable and eco-friendly solutions.

Ballast-free systems

Ballast water discharges can carry invasive species from one territory to another, disrupting the balance in the ocean and causing contamination. Ballast-free systems eliminate this issue and follow guidelines from the International Maritime Organization (IMO).

Anti-fouling hull paint

The exterior coating of ships historically contained hazardous chemicals and degradable materials that pollute waters, attract marine growth, and slow the ship down over time. Anti-fouling paints are safer for the environment and help preserve the hull's exterior, reducing fuel and maintenance costs for shipowners.

Waste management systems

Most marine operators have started adopting new ways of utilizing waste and garbage management for the proper stowage and segregation of scraps such as batteries, food waste, toilet waste, and metallic waste. By prioritizing zero-dumping policies, ships can ensure less trash is thrown into the ocean. A safe and systematic procedure for ecological waste management can minimize cargo ship pollution.

Reception facilities

Most shipping technologies now work with the IMO to provide adequate reception facilities and ensure minimal water pollution. These facilities include proper inspection of ships, standardization of garbage segregation, and attention to the technical aspects of a ship that might lead to an oil leak.

Avoiding sensitive areas

With access to information on sensitive ocean regions, newer technologies have implemented rerouting measures to avoid disrupting the balance in these areas. This is done effectively with technical advancements and training for helmsmen, as well as directional training for shipping.

Low-sulfur fuels

Many newer technologies have adopted the use of fuels with low sulfur content. Lower sulfur fuels reduce cargo ship emissions of diesel combustion in water and the possibility of corroding metals, killing healthy marine bacteria, and carbon storage.

Solar cell propulsion

To reduce fossil fuel consumption and operate in a more environmentally friendly way, the shipping industry is integrating renewable energy technologies. By combining solar and wind power, hybrid models for propulsion are created, reducing harmful emissions and lowering fuel consumption.

Speed adjustments

Large ships that travel at high velocities can burn 280-300 metric tons of sulfur fuel, while traveling at lower speeds can reduce this to 80-90 metric tons. Modern technologies have started incorporating and adjusting time in their travel to reverse or save water from possible pollution levels.

Water pollution from fossil fuels

Fossil fuels, such as coal, oil, and natural gas, have been the primary energy source since the Industrial Revolution, meeting our energy needs for transportation, business operations, and lighting our homes. However, the use of these dirty energy sources has come at a significant cost to the environment and human health, causing water and air pollution, and contributing to global warming.

Secondly, the production and refining of fossil fuels generate enormous volumes of wastewater. This wastewater is often contaminated with heavy metals, radioactive materials, and other toxic pollutants. Improper storage and disposal of this wastewater can lead to leaks or overflows, contaminating nearby waterways and aquifers.

Additionally, the burning of fossil fuels releases a range of harmful pollutants into the atmosphere, including carbon dioxide, sulfur dioxide, nitrogen oxides, and particulate matter. While carbon dioxide contributes to global warming and climate change, pollutants like sulfur dioxide and nitrogen oxides can cause acid rain. When these acidic compounds mix with rainfall, they can be deposited into water bodies, leading to water acidification and further endangering aquatic life.

Furthermore, the transportation and consumption of fossil fuels also pose risks to water bodies. Oil spills and leaks during extraction, transportation, or refining can have devastating impacts on drinking water sources and freshwater or ocean ecosystems. For example, fracking, a method used to extract natural gas, has been linked to increased methane levels in drinking water, posing risks to human health and the environment.

The cumulative effects of water pollution from fossil fuels have severe consequences for both the environment and human well-being. It threatens the survival of marine life, disrupts ecosystems, and contaminates drinking water sources. Additionally, the pollution contributes to climate change, leading to rising sea levels, extreme weather events, and the destruction of habitats.

To address these issues, a transition to cleaner energy sources and the implementation of stricter regulations and waste management practices are essential. Embracing renewable energy sources, such as solar, wind, and hydroelectric power, can help reduce our reliance on fossil fuels and mitigate their harmful impacts on water bodies.

Water pollution from agriculture

Agriculture is a leading source of water pollution in the United States. About 40% of the land in the country is used for agriculture, which supplies a large part of the nation's food, feed, and fiber needs. The intensive use of fertilizers and pesticides in agriculture has led to changes in water quality and the health of stream ecosystems.

Nitrogen-Based Fertilizers

Nitrogen-based fertilizers have been widely used in industrial agriculture, allowing high yields even on overtaxed land. However, they have serious environmental downsides. When excess nitrogen from fertilizers makes its way into the atmosphere, it can become nitrous oxide, a potent greenhouse gas. Nitrogen oxide contributes to ground-level smog. Nitrogen and phosphorus from fertilizers can also cause nutrient runoff, which has detrimental effects on freshwater and marine ecosystems. Nutrient runoff has led to the destruction of fish and shellfish populations in the Chesapeake Bay and has caused recurring "dead zones" in the Gulf of Mexico.

Pesticides

Pesticides are another major contributor to water pollution from agriculture. The U.S. Geological Survey found that pesticides are routinely detected in 88% of streams and rivers. These toxic chemicals have been linked to various chronic diseases, including endocrine (hormone) and neurological disorders, as well as cancer. Children are especially vulnerable to the health impacts of pesticide exposure. Certain pesticides, such as chlorpyrifos, have been associated with developmental delays, lower IQs, and learning disabilities.

Livestock Waste

Livestock and poultry in the United States produce nearly 1.4 billion tons of manure annually, which is often disposed of by spreading it untreated on land. This can lead to runoff into water sources when the amount of manure exceeds the ground's natural absorption rate. Manure is typically stored in vast lagoons before being applied to land, and these lagoons are prone to overflows, leaks, and spills, causing the contents to leach into the soil and groundwater. Livestock waste contains high levels of phosphorus and nitrogen, which can cause eutrophication, or the destructive overgrowth of algae, in water bodies.

Antibiotics

The widespread use of antibiotics in meat production also contributes to water pollution. Antibiotics are used regularly in the food and water of farm animals to help them survive the crowded and unsanitary conditions in concentrated animal feeding operations (CAFOs). This has led to the rise of antibiotic-resistant bacteria, which can spread via air and water, including water used to irrigate crops.
