Reduce plastic consumption and reuse or recycle plastic
Reducing plastic consumption and reusing or recycling plastic are essential steps in reducing water pollution. Plastic is a major cause of pollution and environmental damage, and it takes hundreds of years to decompose. By reducing our plastic consumption, reusing plastic items, and recycling them properly, we can minimise the negative impact of plastic on our planet.
Reducing plastic consumption involves a change in habits and mindset. This can include simple actions, such as switching from plastic to wooden pegs when hanging clothes or choosing plastic-free alternatives like lipstick without microplastics or natural fabric clothing. It's also important to support businesses that reduce plastic packaging and promote sustainable practices. Governments are also playing their part, with Europe banning the sale of single-use plastics like straws, cutlery, and cotton buds in 2021.
Reusing plastic is an important part of reducing waste and protecting the environment. Instead of disposable plastic bags or containers, invest in reusable ones made from durable materials like silicone, glass, or stainless steel. Plastic bottles can be reused as planters, and plastic bags can be reused as trash liners or insulation during winter. Don't forget that plastic items in good condition can be donated to charities or thrift stores.
Recycling plastic is crucial to optimising its lifespan and reducing the need to create new plastic. Most local authorities offer collection facilities for plastic bottles, and many are expanding their collection to include mixed plastics packaging. Some supermarkets and retailers now collect a wider range of plastic bags and soft plastics for recycling. It's important to properly sort and clean plastic items before recycling them and to check with your local authority to ensure you're recycling as many plastics as possible.
By reducing plastic consumption, reusing plastic items, and recycling them properly, we can all play a part in reducing water pollution and protecting our planet from the harmful effects of plastic waste.

Dispose of chemical cleaners, oils, and non-biodegradable items properly
To reduce water pollution, it is important to dispose of chemical cleaners, oils, and non-biodegradable items properly. Improper disposal of these substances can contaminate water sources, harm aquatic ecosystems, and have other detrimental effects on the environment. Here are some detailed, direct, and instructive guidelines for proper disposal:
Chemical Cleaners
When disposing of chemical cleaners, it is crucial to follow the instructions on the product label. Water-soluble cleaning products, such as laundry and dishwashing detergents, multi-surface cleaners, bleaches, and disinfectant cleaners, can generally be flushed down the drain with running water. However, it is important to use only the minimum amount of detergent, bleach, or cleaner needed and choose phosphate-free options whenever possible to minimize their impact on water sources. Additionally, powders should be disposed of in small quantities to prevent lumps in the drain. Solid cleaning products, like bar soaps and scouring pads, can be safely thrown away in the trash. If you have unused or partially used cleaning products that require special handling, such as solvent-based paints or certain pesticides, contact your local household hazardous waste collection program for proper disposal.
Oils
Used cooking oils should never be poured down the drain. Doing so can cause clogged pipes and sewers, leading to sewage backups and water pollution. Instead, properly seal the used oil in a container and include it in your food waste bin for disposal. Alternatively, you can cool or freeze the oil, which makes it easier to handle and dispose of. Some companies that collect household hazardous waste also accept used cooking oil for proper disposal. Check with your local waste management guidelines or contact companies directly to inquire about their collection and disposal processes.
Non-biodegradable Items
When it comes to non-biodegradable items, recycling and proper waste disposal are key to reducing their environmental impact. Educate yourself on the products you purchase and learn the best ways to dispose of them. For example, many plastic cleaning product packages are made from commonly recycled plastics like high-density polyethylene (HDPE) and polyethylene terephthalate (PET). Recycling these plastics helps create a closed-loop system, reducing the need for new plastic production. Additionally, some products labeled as "biodegradable" may not be compostable, so it is important to understand the standards and regulations in your country or region. In the United States, for instance, an item must break down by at least 60% within 180 days in a commercial composting facility to be considered biodegradable.

Maintain your car to prevent leaks of oil, antifreeze, or coolant
Maintaining your car to prevent leaks of oil, antifreeze, or coolant is crucial to reducing water pollution. When these fluids leak from cars, they can contaminate water sources and harm the environment. Here are some essential tips to prevent such leaks and protect our water resources:
Firstly, it is important to understand the cooling system of your car. Antifreeze, also known as coolant, is a vital fluid that is pumped through the engine to regulate its temperature. It absorbs excess heat and exchanges it with the outside air, preventing the engine from overheating. A mixture of antifreeze and water creates "engine coolant," which raises the boiling point of water while lowering its freezing point. This protects the engine from damage caused by extreme temperatures.
To prevent coolant leaks, regular maintenance is key. Follow the manufacturer's recommended maintenance schedule for your vehicle, including routine inspections and fluid changes. This proactive approach can help identify potential issues before they turn into leaks. Additionally, watch out for signs of coolant leaks, such as coloured puddles under your car or a sweet smell before or after driving. These could indicate a problem with the cooling system.
If you suspect a leak, act quickly. Do not ignore the problem or continue driving as this can lead to engine damage and pollution. Instead, bring your vehicle to a certified technician or mechanic as soon as possible for a proper diagnosis and repair. They will be able to identify the source of the leak, whether it's from the radiator, hoses, water pump, reservoir, or a blown head gasket, and provide the necessary repairs.
In addition to maintaining your car, it's important to properly dispose of automotive fluids. Motor oil, antifreeze, and other automotive fluids should never be poured down drains or into sewer systems. Check with your local waste management guidelines or recycling centres to ensure these fluids are disposed of responsibly and do not end up in water bodies.
By maintaining your car, being vigilant about leaks, and disposing of fluids properly, you can help reduce water pollution and keep our environment clean.

Landscape yards with drought-tolerant plants and grasses to reduce runoff
Humans play a significant role in water pollution, and it is our responsibility to take action to reduce it. One effective way to minimise water pollution is to landscape yards with drought-tolerant plants and grasses, reducing runoff and, in turn, preventing water contamination.
Drought-tolerant plants and grasses are essential in reducing water pollution by minimising runoff. Runoff occurs when excess water that the grass or soil cannot absorb flows on top of the ground or pavement. This often happens when irrigation is excessive, and the water is not adequately retained by the soil or absorbed by the plants. By using drought-tolerant plants and grasses, you can effectively reduce runoff and keep water from carrying pollutants into nearby water bodies.
Drought-tolerant plants have evolved adaptations that enable them to survive water scarcity. These adaptations vary among species, but they share the common goal of conserving moisture and adapting to low water availability. For example, some plants have thick and waxy leaves and stems, such as sedum (stonecrop) and other succulents, which trap moisture and reflect sunlight. Other plants have small or thin leaves to minimise water loss through evaporation, such as Santolina, a Mediterranean species.
To enhance the drought tolerance of your yard, consider the following strategies:
- Choose plants native to your region: Native plants from dry or drought-prone areas have often evolved to survive with minimal additional water or maintenance. They are well-adapted to arid conditions and may require less irrigation.
- Incorporate a variety of drought-tolerant species: Include ornamental grasses, floral perennials, dense shrubs, and trees in your landscaping. This adds visual interest and ensures a range of adaptations to water scarcity.
- Practise proper irrigation techniques: Water your lawn infrequently but deeply to encourage the development of deep root systems. Allow your lawn to show signs of wilt before watering again.
- Mulch around garden beds: Mulching helps slow down runoff and water loss through evaporation, conserving moisture in the soil.
- Minimise the use of turf: Turf often requires supplemental irrigation and may not be suitable for long-term survival in all regions. Consider alternatives such as mulched beds or groundcovers like Asiatic jasmine or ivy.
By implementing these strategies and choosing drought-tolerant plants and grasses, you can effectively reduce runoff, minimise water waste, and contribute to the overall reduction of water pollution.

Block livestock from accessing streams, rivers, and other water bodies
Livestock grazing in and around water bodies can have several negative impacts on the environment. Sediment, bacteria, and nutrients are deposited in the waters when livestock are in or next to the water to drink or cool off, leading to increased water turbidity and erosion. This can negatively impact the diversity and abundance of plants and animals in these ecosystems, as well as degrade water quality.
To block livestock from accessing streams, rivers, and other water bodies, fencing is a commonly used method. The placement and design of the fence should consider slope, animal species, and animal and vegetation density. Fence lines should be designed so that livestock trails do not include or border a stream bank or lakeshore. Electrified wire or woven wire fencing can be used, depending on the needs of the livestock and management goals.
In addition to fencing, providing alternative water sources for livestock is crucial. This can be done by creating livestock water access points at impoundments or streams, piping water from these sources to troughs, or using wells, springs, or other water sources to fill troughs. This helps maintain healthy and diverse aquatic and wildlife species while improving their habitat.
Proper planning and management of grazing practices are also essential to reducing the impact of livestock on water bodies. Rotational grazing, which involves moving livestock from pasture to pasture, can help maintain vegetation and reduce erosion. Additionally, providing adequate rest for desirable plants after grazing allows them to recover before the site is grazed again.
By implementing these measures, farmers and ranchers can help prevent water pollution and protect the natural resources that are so important to both the environment and their communities.

Human activity is a major contributor to water pollution, with industrial waste, pesticides, bacteria, fertilizers, and plastics being the main culprits. Human-made pollutants, such as chemicals and microplastics, are washed into groundwater by rain or surface runoff, contaminating water supplies.
Water pollution can occur in the form of transboundary pollution, where contaminated water from one country spills into the waters of another. It can also be caused by disasters such as oil spills or the slow, downriver creep of industrial, agricultural, or municipal discharge. Our rivers, reservoirs, lakes, and seas are often contaminated with chemicals, waste, plastic, and other pollutants, which can have detrimental effects on aquatic ecosystems and disrupt the food chain.
