Water Pollution: Home Habits Harming Our Oceans

Water pollution is a pressing issue, with unsafe water causing illness in about 1 billion people annually. While industrial waste is a major contributor, individual actions can also have a significant impact. At home, water pollution can occur through the improper disposal of household chemicals, such as cleaning agents, medications, and oils, which can reach and contaminate water supplies. Plastic pollution is another significant concern, with microplastics pervading water sources and potentially causing health issues. Additionally, the use of pesticides and fertilizers in yards can lead to toxic chemical runoff into water bodies. Implementing simple changes, such as proper waste disposal, reducing plastic consumption, and adopting eco-friendly landscaping practices, can help mitigate water pollution and protect our precious water resources.

Disposing of household chemicals, medicines, and oils down the sink or toilet

When it comes to household chemicals, it is crucial to never pour them down the sink or flush them down the toilet. This includes substances like metal polishes, wood polishes, waxes, and other solvent-based cleaners. These chemicals can contaminate water sources and pose risks to aquatic life and ecosystems. Instead, it is recommended to store them until they can be disposed of through a household hazardous waste collection program. This ensures that the chemicals are handled and disposed of properly by trained professionals.

Similarly, disposing of medicines down the sink or toilet is not advisable. Unused or expired medications should be returned to a drug take-back location, such as a local pharmacy or police station, where they can be safely disposed of. If a take-back location is not accessible, some medicines may be disposed of in the trash. However, it is crucial to first check the FDA's Flush List to determine if a particular medicine needs to be flushed. This list includes medicines that are especially dangerous if taken, even in small doses, by children or pets.

In the case of oils, it is important to distinguish between cooking oil and engine oil. Cooking oil should not be poured down the sink as it can mix with other substances in the sewer system, leading to clogs and fatbergs. Instead, it is recommended to collect cooking oil in a separate container and dispose of it as solid waste. On the other hand, engine oil is environmentally unsafe and illegal to dispose of down the sink. Proper disposal methods for engine oil may vary, and it is important to refer to local guidelines or waste management authorities for specific instructions.

Overall, it is essential to handle the disposal of household chemicals, medicines, and oils with care and responsibility. By following proper disposal methods, we can help protect our water sources, ecosystems, and public health.

Using pesticides and herbicides

Pesticides and herbicides are chemical products designed to kill or control pests, including insects (insecticides), weeds (herbicides), and fungi (fungicides). They are commonly used in homes and gardens to maintain lawns, control weeds, and protect crops from insects and other pests. While these substances are effective in their intended purpose, they can also have detrimental effects on the environment and human health when they enter water sources.

Pesticides and herbicides contain toxic chemicals that can contaminate water supplies. When applied to crops, lawns, or gardens, these chemicals can be washed off by rainwater and seep into the groundwater. Once in the groundwater, they are challenging to remove and can lead to increased energy consumption during the treatment process. The presence of these toxic chemicals in water sources poses risks to humans, animals, aquatic organisms, and plants.

The solubility of pesticides plays a crucial role in their impact on water pollution. Higher solubility increases the risk of leaching, allowing pesticides to more easily dissolve and contaminate water sources. The persistence of residual herbicides in the soil can also lead to other environmental concerns. Additionally, the application rate of pesticides matters; the larger the amount applied, the longer significant concentrations of these chemicals remain in the environment.

Irrigation practices can further contribute to water pollution by increasing the likelihood of pesticides reaching groundwater and surface water. When irrigating saturated soils or at a rate exceeding the soil's infiltration capacity, runoff can occur, carrying pesticides with it and facilitating their entry into water systems.

To reduce the impact of pesticides and herbicides on water pollution, it is essential to explore alternative options. Instead of synthetic pesticides and herbicides, consider using natural alternatives such as diatomaceous earth, neem oil, organic weed killers, or even natural pesticides. By being mindful of the products we use and their potential environmental impact, we can help protect our water sources and the ecosystems they support.

Plastic consumption

Plastic pollution has become one of the most pressing environmental issues, as the increasing production of disposable plastic products has overwhelmed many countries' waste management systems. This is particularly evident in developing Asian and African nations, where garbage collection systems may be inefficient or non-existent. However, even in developed countries with low recycling rates, the proper collection and disposal of plastic waste can be challenging. As a result, plastic trash has become ubiquitous, prompting efforts to create a global treaty to address plastic pollution.

One of the significant issues with plastic consumption is the improper disposal of plastic waste, which can lead to pollution of our waterways. Rivers are the main source of ocean plastic pollution, carrying plastic trash from land to sea. Once plastic waste reaches the ocean, it is challenging, if not impossible, to retrieve. Mechanical systems can be effective at removing large pieces of plastic from inland waters, but once plastics break down into microplastics, they become virtually impossible to recover. These microplastics can be spread by ocean currents worldwide and have been found in various environments, from Mount Everest to the deepest parts of the ocean.

Microplastics pose a severe threat to marine life and potentially human health. Animals can ingest microplastics, mistaking them for food, or become entangled in larger pieces of plastic. Additionally, plastic pollution can release toxic chemicals as it degrades, which can have harmful effects on the environment and potentially human health. While the long-term health impacts of microplastics are not yet fully understood, studies indicate that plastic can pass through the blood-brain barrier in mice within two hours of consumption.

To address plastic consumption and its impact on water pollution, individuals can take steps to reduce their plastic use. This includes urging elected officials to implement legislation that discourages plastic bag use, such as bans or fees, and supporting better product design and waste management systems. As consumers, we can also be mindful of our purchasing habits, choosing products with minimal or non-plastic packaging and opting for bulk containers instead of multiple smaller, individually packaged items. By making conscious choices and advocating for change, we can help reduce plastic consumption and its impact on water pollution.

Sewage

Improperly maintained or failing septic systems in households can also lead to untreated sewage polluting local waterways. It is essential to properly dispose of household chemicals, medications, and other waste to prevent them from entering sewage systems and causing further pollution.

To reduce sewage pollution, it is important to properly maintain septic systems and dispose of waste responsibly. This includes not flushing medications, dumping paints, or pouring household chemicals down the drain. Additionally, picking up pet waste and disposing of it properly is crucial, as it can otherwise contribute harmful bacteria and nutrients to local waterways.

While sewage may not be the most prominent pollutant, it is essential to address it to protect our oceans and marine life. By taking responsibility for our waste and properly maintaining our septic systems, we can reduce the impact of sewage pollution on the environment.

Pet waste

To prevent water pollution from pet waste, it is crucial to properly dispose of it. This means picking up after your pet and not allowing their waste to be washed into waterways or storm drains. Many local governments and communities are taking steps to address this issue by installing pet waste disposal systems in public spaces, such as parks. These systems act as miniature septic tanks, using enzymes and bacteria to turn dog waste into a harmless, odourless liquid that can be absorbed into the ground.

As a responsible pet owner, you can also take individual action by properly disposing of pet waste in your own yard or when walking your pet in public spaces. Always carry a bag or scoop when walking your dog to pick up and dispose of their waste responsibly. You can also explore installing a pet waste disposal system in your yard, similar to those found in parks.

Additionally, it is important to be mindful of the impact that pet waste can have on local water sources. Avoid allowing pet waste to accumulate near waterways, such as creeks, rivers, or lakes, as it can contaminate these water sources and harm the aquatic ecosystem. By taking these simple steps, you can help reduce water pollution and contribute to a healthier environment for everyone.
