Lifestyle Choices: Impacting Water Pollution And Quality

Water pollution is a pressing issue that poses a significant threat to both human health and the environment. It occurs when harmful substances, such as chemicals and microorganisms, contaminate bodies of water, making them unsafe for human use and damaging aquatic ecosystems. While natural factors like mercury filtration from the Earth's crust contribute to water pollution, human activities are the primary cause.

Lifestyle choices and habits play a crucial role in water pollution. For instance, the use of single-use plastics, improper disposal of waste, and excessive pesticide and fertiliser application in agriculture can all lead to water contamination. Additionally, industrial activities, including chemical dumping and untreated wastewater discharge, are major contributors to water pollution.

The consequences of water pollution are far-reaching. It endangers the health of millions worldwide, causing diseases such as diarrhoea, cholera, and cancer. It also disrupts biodiversity, contaminates the food chain, and hinders economic growth, especially in regions heavily reliant on agriculture and fishing.

Addressing water pollution requires collective efforts to reduce plastic consumption, properly dispose of waste, and implement sustainable agricultural and industrial practices. By making conscious lifestyle changes, individuals can play a vital role in mitigating water pollution and protecting this precious resource.

Industrial and agricultural chemicals

Synthetic fertilizers, which are commonly used in industrial crop production, contain high levels of nitrogen and phosphorus. When excess amounts of these nutrients are applied to farm fields, they can leech into surface and groundwater, causing algal blooms and nitrate contamination. This can impact drinking water supplies and lead to severe health problems for nearby residents. For example, elevated nitrate levels in drinking water can cause low oxygen levels in infants ("blue-baby syndrome") and low birth weight.

In addition to synthetic fertilizers, animal waste from concentrated animal feeding operations (CAFOs) or factory farms is another significant source of water pollution. These operations generate millions, if not billions, of gallons of animal waste annually, which is often stored in pits or open ponds called lagoons. These waste-containment areas are prone to leaking and rupturing during storms, allowing waste to contaminate surface and groundwater. Animal waste can also contain pharmaceutical residues, heavy metals, and harmful bacteria, which can leech into water supplies and pose risks to both human and aquatic health.

The use of pesticides in crop agriculture is another contributor to water pollution. These toxic chemicals have been linked to various chronic diseases, including endocrine and neurological disorders and cancer. They are routinely detected in streams and rivers and have been found in the bodies of a large majority of Americans.

To reduce the impact of industrial and agricultural chemicals on water pollution, it is important to minimize the use of synthetic fertilizers and pesticides, properly manage and treat animal waste, and promote sustainable farming practices that prioritize the protection of water resources.

Sewage and wastewater

The impact of sewage and wastewater on the environment is largely negative. If only partially treated or left untreated, sewage can contaminate water bodies and harm aquatic life. For example, a sewage leak in the River Trent in Staffordshire resulted in the death of over 15,000 fish. Additionally, sewage contamination can facilitate the spread of diseases such as E. coli, diarrhea, and hepatitis A.

Wastewater treatment facilities play a crucial role in reducing the amount of pollutants in sewage before it is discharged back into waterways. However, aging and overwhelmed sewage treatment systems can also release billions of gallons of untreated wastewater each year, as seen in the United States.

To mitigate the negative impact of sewage and wastewater on the environment, proper treatment and disposal of wastewater are essential. This includes reducing the use of chemical pesticides and nutrients on crops, safely treating and reusing wastewater, and implementing nature-based solutions such as constructed wetlands for wastewater treatment.

Plastic and garbage

Plastic waste is harmful to both marine life and human health. Marine animals such as turtles, seabirds, and fish often mistake plastic debris for food, which can lead to fatal outcomes. Plastic can block their digestive tracts or pierce their organs, causing death. In addition, microplastics—small particles of plastic less than 5mm in size—have been found in marine animals, indicating that they are being passed through the digestive system and expelled without consequence. However, the effects of microplastics on human health are still being studied.

The main sources of plastic and garbage pollution in water include debris falling off ships, trash blowing into the ocean from landfills, garbage swept into the sea via rivers, and people throwing trash onto beaches. Much of the plastic pollution in the ocean comes from fishing boats, tankers, and cargo shipping. Additionally, food containers and packaging are the largest components of municipal solid waste and marine debris.

To reduce plastic and garbage pollution in water, individuals can take simple actions such as refusing and reducing plastic usage, carrying reusable bags, patronizing zero-waste businesses, and bringing reusable bottles and cutlery. On a larger scale, governments can implement policies to ban or limit the use of plastic bags and other single-use plastics. Improved waste management systems, better product design, and reduced manufacturing of unnecessary single-use plastics are also necessary to address this issue.

Oil pollution

The impact of oil pollution is devastating for marine life. Oil can smother vegetation and wildlife, with birds and marine animals suffering the most. Oil-coated birds struggle to insulate themselves and fly, and when they clean themselves, they ingest the toxic substance. Most oiled birds do not survive without human intervention. Fish can suffocate due to the thick oil sludge, and bottom-dwelling fish may develop liver disease and reproductive issues. Oil spills also harm plants that grow in or near the water by blocking sunlight, disrupting photosynthesis, and killing them.

To address oil pollution, several methods are employed, including manual clean-up using shovels, trucks, and vacuum trucks, and the use of skimmers, booms, and sorbents to contain and absorb the oil. Chemical dispersants are also used to speed up the natural process of oil breakdown, but their long-term effects are unknown. Bioremediation, utilising natural microorganisms to break down oil, is another approach, especially in sensitive areas where human intervention may cause more damage.

To reduce the impact of oil pollution on water sources, proper disposal of oil, paint, and hazardous chemicals is crucial. Individual actions, such as recycling used oil and preventing oil from entering storm drains, can make a significant difference. Additionally, international treaties like MARPOL have been implemented to prevent pollution from ships, requiring the use of oil-pollution prevention equipment and imposing restrictions on discharges near land.

Radioactive waste

Water pollution is a serious issue that can directly impact human health and the environment. It occurs when water becomes contaminated by chemicals, microorganisms, or other harmful substances. One significant source of water pollution is radioactive waste, which can have detrimental effects on aquatic ecosystems and human health.

Nuclear accidents or improper waste disposal practices can result in the release of radioactive materials into the environment. For example, the Fukushima Daiichi nuclear power plant disaster in Japan, caused by an earthquake and tsunami, released thousands of tons of radioactive water into the Pacific Ocean. Similarly, low levels of radioactive waste have been discharged into the Irish Sea, the English Channel, and the Arctic Ocean since 1952.

The effects of radioactive water pollution on human health can be dire. Consuming contaminated water or seafood can result in various health issues, including altered brain function, damage to the immune and reproductive systems, and cardiovascular and kidney problems. Additionally, swimming in polluted water can trigger respiratory infections.

To mitigate the impact of radioactive waste on water pollution, proper containment and disposal practices are crucial. Radioactive materials should be isolated and encased in glass and concrete to prevent leakage. Radioactivity levels should also be allowed to decrease over time before disposal. By implementing stringent measures and responsible waste management strategies, the risks associated with radioactive waste in water pollution can be reduced.
