Creating Water Pollution: A Comprehensive Guide

Water pollution is a pressing issue that affects one in three people worldwide, according to the United Nations. It is caused by a variety of factors, including industrial waste, pesticides, bacteria, fertilizers, and plastics. These pollutants contaminate water sources such as rivers, lakes, and oceans, making the water toxic and unsuitable for drinking or essential purposes like agriculture. The consequences of water pollution are dire, causing approximately 1.8 million deaths in 2015 and making about 1 billion people ill annually. With rising global temperatures and increasing population, the urgency to address water pollution becomes even more critical. While individual actions might seem insignificant, they can collectively create a significant positive impact. This introduction will explore the causes, effects, and potential solutions to water pollution, highlighting the importance of collective efforts in tackling this global challenge.

Polluting oceans, rivers, lakes, canals and reservoirs

Water pollution occurs when harmful substances contaminate a body of water, degrading water quality and rendering it toxic to humans or the environment. This can include oceans, rivers, lakes, canals, and reservoirs. Here are some ways that these water sources can become polluted:

Oceans

The transportation and storage of oil and its derivatives are subject to leakage that can pollute ocean waters. Much of the plastic pollution in the ocean also comes from fishing boats, tankers, and cargo shipping. In addition, the UN states that more than 80% of the world's sewage finds its way into the oceans untreated.

Rivers

Rivers can become polluted through agricultural practices, with fertilizers, pesticides, and animal waste from farms and livestock operations washing into waterways. They can also be polluted by untreated sewage and plastic pollution.

Lakes

Lakes can be polluted by a variety of sources, including rainfall, storm events, lawn sprinklers, car washing, and the improper disposal of sewage, trash, and chemicals. They are also susceptible to pollution from nearby urban development, as concrete and other impervious surfaces can cause polluted rainfall to accelerate into lakes instead of soaking into the ground.

Canals and Reservoirs

Canals and reservoirs are human-made water bodies that can be susceptible to many of the same pollution sources as natural water bodies, including sewage, trash, chemicals, and agricultural runoff. They can also be affected by pollution from nearby urban areas.

Using household chemicals or cleaning agents

Water pollution is the addition of harmful substances to water, and it can occur when household chemicals are not disposed of properly. Many household chemicals found on store shelves biodegrade slowly or not at all, and instead form even more toxic compounds. These chemicals can contaminate water and affect both wildlife and human health.

One way that household chemicals can contribute to water pollution is through improper disposal down household drains, toilets, sinks, or sewers. It is important to never dispose of household chemicals or cleaning agents in this way. This includes chemicals such as bleach, pesticides, cleaning solvents, motor oil, paints, medications, and other hazardous waste. These chemicals can contain toxic substances, such as chlorine, that can harm aquatic life and contaminate water sources.

To prevent water pollution, it is essential to follow local hazardous waste disposal guidelines and properly dispose of household chemicals. Many cities have hazardous waste collection days where residents can bring their waste to a designated location for proper disposal. It is also important to choose eco-friendly and non-toxic alternatives to harsh household chemicals and cleaning agents whenever possible. These products are safer for the environment and can help reduce water pollution.

In addition to proper disposal and choosing eco-friendly products, there are other ways to reduce water pollution in your home. This includes fixing leaky plumbing fixtures, using low-flow toilets and showerheads, and being mindful of water usage. By making conscious choices and adopting more sustainable practices, we can all contribute to reducing water pollution and protecting our environment.

Dumping waste into street drains

Water pollution is a severe issue that affects our rivers, reservoirs, lakes, and seas, which are being contaminated by chemicals, waste, plastic, and other pollutants. One of the leading causes of water pollution is nonpoint source pollution, which includes agricultural or stormwater runoff and debris blown into waterways from the land.

Stormwater runoff is a significant contributor to water pollution, as many people mistakenly believe that storm drains lead to wastewater treatment plants. In reality, in many urban and rural areas, water entering these drains receives no treatment and is discharged directly into the nearest waterway. This means that any waste dumped into street drains will likely end up in local streams, rivers, or other bodies of water, untreated.

To prevent water pollution via street drains, it is essential to properly dispose of waste and avoid dumping anything into these drains. This includes litter and debris, cigarette butts, pet waste, lawn and garden chemicals, automotive fluids, dirty wash water, and any other form of waste. Instead, waste should be disposed of in trash cans, ashtrays, or hazardous waste collection sites, depending on the type of waste. Additionally, it is recommended to sweep or blow lawn debris, such as leaves and grass clippings, onto your lawn rather than into the street or storm drains.

Poorly maintained septic systems

Poor maintenance of septic systems can cause water pollution, which can have serious consequences for human health and the environment. Septic systems are used by many homeowners to treat household wastewater, and when properly maintained, they can effectively treat sewage and even help replenish groundwater supplies. However, if neglected, they can become a source of water pollution, contaminating nearby water bodies and groundwater sources.

One of the main issues with poorly maintained septic systems is their proximity to water sources. If a septic system is located too close to a drinking water well or a water body, contaminants from the wastewater can easily find their way into these sources. This can result in the presence of disease-causing pathogens, such as E. coli, Salmonella, and other bacteria, viruses, and protozoa. These contaminants can lead to serious illnesses, including typhoid, gastrointestinal issues, hepatitis A, and cholera.

Another consequence of poor septic system maintenance is the impact on groundwater quality. Groundwater is highly vulnerable to pollution from septic systems, especially from unabsorbed phosphorus, which can end up in lakes, rivers, and other water bodies. Nitrogen is also a significant concern, as it can flow into surface waters and cause health problems, especially in infants, who are susceptible to the effects of high nitrate levels, leading to a condition known as "blue baby syndrome".

To prevent water pollution from poorly maintained septic systems, regular maintenance and evaluation are crucial. Homeowners should follow guidelines and best practices, such as pumping out the tank every three to five years, minimising the use of harsh chemicals, and properly disposing of waste. By taking proactive measures, the risk of system failure and subsequent water pollution can be significantly reduced, protecting both human health and the environment.

In summary, poorly maintained septic systems can have far-reaching impacts on water quality and public health. Proper maintenance, including regular pumping, proper waste disposal, and monitoring for signs of failure, is essential to prevent water pollution and its associated risks. By being vigilant and proactive, homeowners can play a crucial role in safeguarding their own health, their community, and the surrounding natural environment.

Untreated sewage

One of the primary consequences of untreated sewage is the contamination of water sources. When sewage goes untreated, it releases harmful pollutants such as bacteria, viruses, parasites, and chemicals into water bodies. These pollutants can infiltrate groundwater, rivers, lakes, and oceans, making the water unsafe for human and animal consumption. According to the United Nations, more than 80% of the world's wastewater flows back into the environment without proper treatment, leading to a significant decline in water quality.

Moreover, untreated sewage has devastating effects on ecosystems and wildlife. The high levels of nutrients, pathogens, endocrine disruptors, heavy metals, and pharmaceuticals in untreated sewage can fuel harmful algal blooms. These blooms deplete oxygen levels in water bodies, leading to fish die-offs and a decline in aquatic life. Additionally, sewage pollutants can disrupt the delicate balance of marine ecosystems, particularly coral reefs, which are essential for maintaining marine biodiversity and spawning.

To address the issue of untreated sewage, several measures can be implemented:

• Regular maintenance and prompt repair of septic systems to prevent leaks and spills.
• Proper waste disposal, especially for hazardous materials, plastics, and non-biodegradable items, to reduce the load on sewage treatment facilities.
• Reducing water usage to lessen the chance of overflows and the strain on treatment facilities.
• Investing in wastewater management solutions, such as advanced on-site sewage processing plants and effluent disposal systems, to efficiently remove pollutants.
