Reducing Water Pollution: Strategies For The United States

Water pollution is a critical issue in the United States, threatening drinking water sources and causing harm to human health, wildlife, and the environment. It is essential to address this problem and implement effective solutions to reduce water pollution and protect this vital resource. Water pollution has various causes, including industrial waste, agricultural runoff, household waste, septic systems, stormwater runoff, and oil spills, each contributing to the contamination of water bodies. Understanding the root causes and working together at individual, community, and governmental levels is key to tackling this issue.

Reduce, reuse, and recycle

Water pollution is a pressing issue in the United States, and it's essential to address it through a combination of reduction, reuse, and recycling strategies. Here are some detailed ways in which these principles can be applied to help reduce water pollution in the country:

Reduce

• Individuals can reduce water waste in their homes and workplaces. This reduces the amount of fuel and chemicals needed for heating and pumping water, thereby lowering pollution levels.
• Install water-efficient showerheads and low-flow toilets to minimize water usage.
• Opt for shorter showers and shallower baths.
• Turn off the tap while brushing teeth or shaving.
• Compost food scraps instead of using a garbage disposal in the sink.
• Only run the washing machine with a full load, using warm or cold water instead of hot.
• Minimize lawn areas and opt for drought-tolerant plants and grasses to reduce the need for excessive watering.
• Use porous pavement, such as gravel, for driveways and walkways to allow rainwater to recharge groundwater supplies instead of contributing to erosion.
• Wash your car less frequently, and when you do, use a bucket of soapy water instead of a running hose.

Reuse

• Reuse greywater, which is wastewater from bathroom sinks, bathtubs, and clothes washing equipment drains, for landscape irrigation or toilet flushing.
• Recycled water can be used for non-potable purposes such as agriculture, landscape irrigation, public parks, and golf course irrigation.
• Reuse water for industrial processes, such as cooling water for power plants and oil refineries, and processing water for mills and plants.
• Decentralized water reuse systems, particularly in arid regions, can help meet water demands while preserving freshwater sources.

Recycle

• Recycle treated wastewater for beneficial purposes such as agricultural and landscape irrigation, industrial processes, and replenishing groundwater basins.
• Advanced treatment processes, such as reverse osmosis, can be used to remove impurities from wastewater, making it suitable for reuse.
• Recycled water can be used to recharge groundwater aquifers and augment surface water reservoirs, ensuring a more sustainable water supply.
• Recycling water reduces the energy required to treat and transport water over long distances or pump it from deep within aquifers.

Dispose of chemicals and medicines properly

Water pollution is a pressing issue in the United States, with agricultural pollution being the top source of contamination in rivers and streams, and a significant contributor to the pollution of lakes, estuaries, and groundwater. While the Clean Water Act has helped to improve water quality, there is still much to be done to address the issue of water pollution. One crucial aspect is the proper disposal of chemicals and medicines.

The improper disposal of chemicals and medicines can have detrimental effects on water sources. It is important to never pour hazardous waste down the drain, on the ground, or into storm sewers. These include leftover paints, chemicals, and certain medicines. Instead, individuals should contact their local public works department or environmental health department to find out if their city has a hazardous waste collection day. If not, citizens can request that their city starts one.

For medications, it is important to never flush them down the toilet or pour them down the drain. This is because wastewater treatment plants are often unable to remove drugs from the sewer system, leading to their presence in rivers and streams. Instead, individuals should take advantage of pharmaceutical take-back programs that accept unused or expired prescription and over-the-counter drugs. These programs ensure that unwanted medicines are disposed of in a safe and environmentally conscious manner.

Additionally, individuals can reduce their use of hazardous chemicals by opting for non-toxic household products, such as cleaning supplies, laundry products, paints, insecticides, and pool chemicals. Using natural fertilizers, such as manure, compost, or mulch, can also help reduce the impact on water sources.

By properly disposing of chemicals and medicines, individuals can play a crucial role in reducing water pollution and protecting the environment.

Use water-efficient products

Water-efficient products are a great way to reduce water pollution. Here are some ways to use water-efficient products to reduce water pollution:

• Install water-efficient showerheads (2.5 gallons or less per minute). Taking shorter showers and drawing less water for baths are also effective ways to conserve water.
• When buying a new toilet, opt for a low-flow model (1.6 gallons or less per flush). You can also put a brick or a 1/2 gallon container in your toilet tank to reduce water use per flush.
• Turn off the water while brushing your teeth and shaving.
• Only run the dishwasher or clothes washer with a full load of dishes or clothes. This conserves electricity and water.
• Water your garden before the sun comes up or after it sets. You'll need to use more water during the hottest times of the day, so watering your plants in the early morning or evening will help you save water.
• If you have a sump pump or cellar drain, make sure it doesn't drain into the sanitary sewer system.
• Install a drip-irrigation water system for valuable plants.

Using water-efficient products is a simple and effective way to reduce water pollution. By conserving water, we can also reduce the pollution generated by treating water with chemicals and burning fuel to heat and pump it.

Participate in community clean-up events

Participating in community clean-up events is a fantastic way to reduce water pollution in the United States. Here are some ways to get involved:

Beach Clean-ups

Coastal clean-ups are a great way to reduce ocean water pollution. Marine debris, such as plastic, is a significant contributor to ocean pollution, as it can strangle, suffocate, and starve marine animals. Joining a beach clean-up event helps remove this debris before it enters the ocean. You can also organize your own clean-up event with local community groups or schools.

River and Stream Clean-ups

Rivers and streams are often heavily polluted due to agricultural and industrial activities. Participating in a river or stream clean-up event can help remove trash and debris that have accumulated in these waterways. These events often involve canoeing or kayaking to collect trash, and they are a great way to improve water quality and protect aquatic ecosystems.

Lake and Reservoir Clean-ups

Lakes and reservoirs are also vulnerable to pollution from various sources. Participating in a lake or reservoir clean-up event can involve removing trash and debris from the shoreline or, for divers, underwater clean-up efforts. These events help protect the water quality and the health of the aquatic life that depends on these freshwater ecosystems.

Storm Drain and Sewer Clean-ups

Storm drains and sewers are often overlooked but critical areas for addressing water pollution. Participating in a storm drain or sewer clean-up event can involve removing debris that has accumulated in these systems, such as litter, leaves, and other materials that can block drains and contribute to flooding. These events help prevent water pollution and reduce the risk of street floods during heavy rainfall.

Community Education and Outreach

In addition to participating in clean-up events, you can also get involved by educating your community about water pollution and ways to reduce it. This could include organizing workshops, giving presentations at schools, or participating in community meetings to share information about the unique water pollution challenges in your area and simple actions that individuals can take to make a difference.

Implement stormwater management practices

Stormwater management is a critical aspect of reducing water pollution in the United States. Effective stormwater management practices aim to reduce runoff, improve water quality, and minimize erosion, flooding, and downstream water pollution. Here are some detailed strategies and techniques that fall under stormwater management:

Low Impact Development (LID) and Green Infrastructure

The United States Environmental Protection Agency (EPA) employs LID practices and green infrastructure at its facilities to manage stormwater sustainably. LID practices help maintain natural hydrologic cycles by utilizing site grading, vegetation, soils, and natural processes to absorb and filter stormwater onsite. This approach reduces runoff, improves water quality, and lessens the negative impacts of erosion and flooding.

Permeable Pavement and Surfaces

Instead of using impermeable surfaces like asphalt or concrete, which contribute to stormwater runoff, the EPA has implemented permeable pavement in some of its parking lots, driveways, and sidewalks. Permeable surfaces allow stormwater to infiltrate through porous materials into the soil and groundwater, reducing the volume of runoff. Examples include pervious concrete, porous asphalt, and interlocking paver blocks.

Green Roofs

The EPA has installed green roofs on several of its offices, including in Boston, Denver, Seattle, and Narragansett. Green roofs are covered with vegetation, which enables rainfall infiltration and evapotranspiration of stored water. They offer multiple benefits, such as reducing atmospheric pollution, lowering energy costs, mitigating the "heat island" effect, and creating aesthetically pleasing environments.

Bioretention Areas and Rain Gardens

Bioretention areas, also known as rain gardens, are shallow, landscaped depressions that allow stormwater runoff to pond and then filter through soil and vegetation. These areas help to slow down and treat the stormwater before it enters the drainage system, reducing the impact of pollutants.

Vegetated Swales and Dry Swales

Swales are drainage paths or vegetated channels used in place of underground storm sewers or concrete open channels. They help to slow down and direct stormwater runoff, facilitating infiltration and filtering pollutants as the water flows through the system.

Constructed Wetlands

Constructed wetlands are designed to mimic natural wetlands, capturing and filtering stormwater while creating diverse wildlife habitats. They can contain standing water on the surface or just below the soil surface. These wetlands help to treat stormwater and provide valuable ecosystems for various species.

Curb and Gutter Elimination

Curbs and gutters rapidly collect and transport stormwater runoff to drains without allowing for infiltration or pollutant removal. By eliminating curbs or adding curb cuts, runoff can be directed into pervious areas and filtered through LID features, reducing the volume of polluted water entering water bodies.

These practices and techniques outlined above are just a few examples of how stormwater management can be implemented to reduce water pollution in the United States. By adopting these strategies, communities can improve water quality, minimize the negative impacts of runoff, and protect aquatic ecosystems.
