Reducing Water Pollution: Strategies For A Cleaner Future

Water pollution is a pressing issue that threatens aquatic ecosystems and the health of humans, plants, and animals that depend on them. One way to decrease water pollution is to implement better waste management practices. This includes proper disposal of trash, oils, chemicals, and other pollutants, as well as the use of septic tanks and treatment of stormwater. Additionally, water conservation practices, such as using water-efficient toilets and appliances, reducing pesticide and fertilizer use, and minimizing water usage can also help decrease water pollution.

Reduce water usage

Reducing water usage is a critical step in decreasing water pollution. By conserving water, we can ensure that this precious resource is used efficiently and sustainably, reducing the impact on aquatic environments and the diverse plants and animals that depend on them. Here are some ways to reduce water usage:

Install Water-Efficient Products

Look for WaterSense-labelled products, which are independently certified to meet EPA's criteria for efficiency and performance. These products include faucet aerators, plumbing fixtures, and irrigation systems. WaterSense-labelled products can help you save water and reduce your energy bills.

Fix Leaks and Be Mindful of Water Usage

Small household leaks can add up to significant water loss over time. Regularly check for leaks and fix them promptly. Be mindful of your water usage habits, such as turning off the tap while shaving or brushing your teeth, and taking shorter showers instead of baths.

Efficient Landscaping and Gardening

Native plants require less water and care than ornamental varieties. Use mulch around garden plants to reduce evaporation and cut down on weed growth. Remove thatch and aerate turf to improve water absorption. Raise the cutting height of your lawnmower to promote longer grass blades, which help shade each other and reduce evaporation. Minimise or eliminate fertiliser use, as it requires additional watering and promotes new growth that also needs more water.

Water Management and Conservation

Water your plants in the early morning or evening to minimise evaporation. Use porous pavement, such as gravel, instead of asphalt to allow rainwater to recharge groundwater supplies. Sweep driveways and sidewalks instead of hosing them down. Wash your car less frequently, and when you do, use a bucket of soapy water or consider a commercial car wash that recycles water.

Efficient Agriculture Practices

Agriculture is a significant water user, accounting for up to 70% of surface water supplies. Adopting green agriculture practices, such as using pesticides and fertilisers without harmful chemicals, can help reduce water pollution. Additionally, proper stormwater management techniques, such as reverse osmosis, advanced oxidation, and sand filtration, can prevent pollutants from reaching water bodies.

Install water-efficient fixtures

Water pollution is a pressing issue that requires immediate attention and action. One effective way to combat this problem is to install water-efficient fixtures, which can significantly reduce water waste and conserve this precious resource. Here are some detailed ways to implement this strategy:

Install Water-Efficient Toilets

Toilets equipped with two buttons, one for a small flush and the other for a full-power flush, are a step in the right direction. These water-efficient toilets allow you to conserve water by using less for liquid waste, with the small flush using as little as 0.8 to 1.1 gallons of water. Additionally, consider retrofitting your existing toilets with water-saving devices, such as dual-flush mechanisms or water-saving flush valves.

WaterSense Faucet Aerators and Showerheads

Faucet aerators are an excellent way to decrease water flow through taps, reducing consumption by up to 50%. Installing WaterSense labeled faucet aerators and showerheads can help regulate water flow and save a significant amount of water. These fixtures are suitable for both residential and municipal buildings.

Efficient Irrigation Practices

Implementing efficient irrigation practices, such as drip irrigation or xeriscaping, can minimize water waste in landscaping and gardening. Drip irrigation delivers water directly to the plant's root zone, reducing evaporation and overspray losses. Xeriscaping involves using native, drought-tolerant plants that require less water, such as succulents, cacti, rockrose, or moss phlox.

Greywater and Rainwater Harvesting

Greywater refers to water used for processes like cooling towers, boilers, or chillers, which can sometimes be reused as process water, conserving potable water. Capturing and storing rainwater for landscape irrigation is another effective strategy. Rainwater collected from roof surfaces is cleaner than stormwater, which can pick up contaminants like oil and other pollutants.

Water-Efficient Appliances

Replace old appliances with water-efficient models. This includes appliances for heating and cooling, such as air-cooled equipment instead of water-cooled options. Additionally, consider using energy-efficient space cooling equipment and turning off cooling units when not in use to minimize water and energy consumption.

By installing water-efficient fixtures and adopting sustainable practices, we can play a crucial role in decreasing water pollution, protecting aquatic ecosystems, and ensuring a sustainable future for ourselves and the planet.

Cut fertiliser use

Agriculture is a trillion-dollar industry worldwide, using up to 70% of surface water supplies for livestock production and farming. As such a large industry, it is one of the primary causes of water pollution. When it rains, runoff transports pesticides and fertilizers, which can wash into storm drains and waterways.

Fertilizers such as nitrogen often end up in water sources and contribute to the acidification of soil. They also cause global warming, prompting soil microbes to emit unexpectedly high levels of nitrous oxide, a greenhouse gas with 300 times the heat-trapping power of carbon dioxide.

However, it is possible to cut back on fertilizer use without negatively affecting crop yields. A large-scale study in China found that simple interventions can produce large results. Over a decade, researchers worked with 21 million smallholder farmers to increase crop yields while reducing the environmental impacts of farming. The researchers provided detailed advice on which variety of crop to use, the best time to plant, how many seeds to sow, and how much fertilizer to use. The result was an average increase of 11% in maize, wheat, and rice production, while fertilizer use was reduced by an average of 15% per crop, saving 1.2 million tonnes of nitrogen.

Farmers can also improve their nitrogen use efficiency (NUE), which is the ratio of nitrogen in harvested products compared to the amount of nitrogen added as fertilizer. A NUE of 60% means that the amount of nitrogen in the crops is 60% of the nitrogen that was added, while the remaining 40% was not used by the crops. A low NUE means very little of the nitrogen added is taken up by the crops, and a high percentage becomes a pollutant.

There are also many "organic" alternatives to chemical fertilizers, such as composts, animal manure, dried blood, bone meal, rock phosphate, and seaweed products. While these alternatives have lower nutrient analyses and solubility than commercial fertilizers, they can successfully fertilize crops.

Adopt a storm drain

Stormwater is rainwater that flows over roads, pavements, and other surfaces. This water can collect harmful pollutants such as bacteria, viruses, pesticides, and fertilizers, which can then enter drains, rivers, and oceans, causing water pollution.

One way to combat this source of water pollution is to adopt a storm drain. This is a program that asks residents to adopt a drain in their neighbourhood and keep it clear of leaves, trash, and other debris. The idea is that by keeping the drain clear, you reduce the amount of water pollution entering the local water systems.

The adoption process is simple and quick, and anyone over the age of 14 (with parental consent) can adopt a drain. Adopters can choose a drain that is easy for them to take care of, such as one near their home, school, or business. The Adopt-a-Drain program provides tips on how to keep the drain clean, as well as a list of common household tools that can be used.

After each cleaning, adopters can log in to the program website and report the amount of debris they have collected. This data is used to estimate the impact of the program and track town-wide results. Cleanup frequency may vary depending on the season and the condition of the drain, but it is recommended that adopters clean their drains at least once a month.

Wash your car less

Washing your car less frequently is a simple way to reduce water pollution. When you do wash your car, there are several ways to minimise the negative impact on the environment.

Firstly, it is important to be mindful of where you wash your car. Washing your car on gravel or a lawn is preferable to washing it on a driveway. This is because the water, along with soap, dirt, grime, grease, and oil, can percolate or soak into the ground, where the soil acts as a natural filter. This prevents the water from flowing directly into storm drains, which lead to lakes, rivers, or streams. If you must wash your car on a driveway, make sure to dump the dirty water into a sink or drain where it can be properly treated, rather than onto the ground.

Using a commercial car wash is an even better option, as the water is recycled and sent to a wastewater treatment facility, ensuring that it is properly treated before being released back into the environment.

Another way to reduce water pollution when washing your car is to be mindful of the products you use. Many soaps contain chemicals that are harmful to fish and other aquatic life, as well as degrading water quality. Some soaps also contain phosphates, which can cause excess algae growth in waterways. This not only looks and smells bad, but it also further harms water quality and uses up the oxygen in the water that fish need to survive. Choosing a soap that is specifically designed to be environmentally friendly and phosphate-free can help to reduce water pollution.

In addition to choosing the right soap, it is important to use it sparingly. Excess soap can wash off your car and into nearby waterways, contributing to pollution. Using a wash mitt or sponge to apply the soap, rather than spraying it directly onto the car, can help to reduce the amount of soap that ends up in the water.

By following these simple tips, you can help reduce water pollution and protect aquatic environments.
