Reduce plastic consumption and reuse or recycle plastic products
China's water pollution is a pressing issue, and while some actions have been taken, such as the State Council's implementation of the Action Plan for Water Pollution Prevention and Control in 2015, there is much more that could have been done to prevent it. One key strategy is to reduce plastic consumption and promote the reuse and recycling of plastic products.
Reducing plastic consumption is essential to preventing water pollution. Plastic has become ubiquitous in our lives, from product packaging to cosmetics and textiles. To reduce plastic use, individuals can switch to reusable alternatives. For example, instead of using plastic bags, individuals can bring their own bags when grocery shopping, including bags for loose produce, avoiding the plastic bags provided and pre-packaged vegetables. Similarly, individuals can switch from using plastic straws, cups, and bottles to reusable options, such as carrying a reusable straw or a travel mug. Even small actions, such as switching from plastic to wooden pegs for hanging clothes, can have a significant positive impact when adopted by many people.
Reusing plastic products is another crucial aspect of preventing water pollution. Plastic bottles and containers, for instance, can be refilled and reused for storing food instead of being discarded after a single use. Approximately 33% of plastic is used only once before being thrown away, contributing to the vast amount of plastic waste that ends up in our oceans and rivers. By reusing plastic items, we can reduce the amount of plastic waste that enters our water bodies and the environment.
Recycling plastic products is a third critical component of preventing water pollution. Individuals can recycle plastic by checking with their local recycling programs to learn which types of plastic they accept. Some communities may offer composting programs for compostable plastics, while others may have drop-off locations for these items. When possible, it is beneficial to purchase products made from recycled plastic materials, supporting a circular economy that prioritizes resource efficiency and reduces the use of new raw materials.
Overall, to prevent water pollution in China, it is essential to reduce, reuse, and recycle plastic products. By implementing these practices, we can help reduce the amount of plastic waste that ends up in our oceans, rivers, and the environment, contributing to a healthier and more sustainable future for both people and the planet.

Properly dispose of chemical cleaners, oils, and non-biodegradable items
China has been listed as one of 13 countries facing water scarcity by the United Nations, with pollution exacerbating the issue. The discharge of industrial wastewater, domestic sewage, agricultural hazardous pesticides, and manure has polluted both surface and groundwater. To prevent water pollution, it is crucial to properly dispose of chemical cleaners, oils, and non-biodegradable items.
Chemical cleaners, if unused, can generally be disposed of down the drain or with other household waste. However, it is important to read the labels and follow any special disposal instructions provided by the manufacturer. Water-soluble cleaning products, such as laundry and dishwashing detergents, multi-surface cleaners, and disinfectant cleaners, can be flushed down the drain with running water. Solid cleaning products, like bar soaps and toilet bowl cleaners, can be safely thrown in the trash. For products requiring special handling, such as solvent-based paints and certain pesticides, household hazardous waste collection programs are available.
Oils, especially cooking oils, should never be poured down the drain as they can cause blockages and sewer problems, contaminate soil, and harm aquatic life. Instead, used cooking oil should be cooled or frozen to solidify, then disposed of in sealed containers with food waste. Alternatively, used cooking oil can be given to restaurants or collected by companies that manage household hazardous waste.
Non-biodegradable items should be recycled or disposed of properly to prevent them from ending up in landfills, where they will not break down. Plastic packaging, for example, is often made from high-density polyethylene (HDPE) or polyethylene terephthalate (PET), both of which are commonly recycled. Communities are increasingly collecting plastic bottles for recycling, and some areas have specific regulations for the collection and disposal of certain types of waste.

Reduce water usage by installing water-efficient toilets and showerheads
China has been facing a water crisis due to pollution and scarcity. The country has been listed as one of 13 countries facing a water shortage by the United Nations. While China's total volume of freshwater resources is 2.8 trillion cubic meters, its per capita water resources are only 2,000 cubic meters, a quarter of the world's average.
Water pollution in China is caused by the discharge of industrial wastewater, domestic sewage, agricultural hazardous pesticides, and manure. This has polluted both surface water and groundwater, with only a small percentage meeting the criteria for drinking water supply sources.
To prevent water pollution and promote sustainable water usage, China has implemented various measures, including the Water Pollution and Control Action Plan in 2015, which aimed to improve water quality and eliminate black odor water in urban areas. China has also constructed municipal wastewater treatment plants and improved its collection and treatment systems for domestic sewage.
One way to reduce water usage and promote conservation is by installing water-efficient toilets and showerheads. Toilets use a significant amount of water, and older models can consume anywhere from 3 to 7 gallons of water per flush. This can result in extremely high water bills and unnecessary water waste.
High-efficiency, low-flow toilets are designed to consume significantly less water, with a federal limit of 1.6 gallons per flush for older low-flow models and as little as 1.1 gallons per flush for newer models. Dual-flush toilets offer two options: a lower volume for liquid waste and a higher volume for solid waste, allowing for further water savings. Pressure-assist toilets use stored air pressure to flush with greater force while consuming just under 1 gallon per flush.
When choosing water-saving showerheads, look for models with a flow rate of 2.0 gallons per minute (GPM) or less. High-efficiency models can use as little as 1.5 GPM while still providing a satisfying shower experience. Faucet aerators can also be attached to existing faucets to reduce water flow by mixing air with the water stream, maintaining pressure while using less water.
By installing water-efficient toilets and showerheads, individuals can reduce their water bills, conserve water, and lessen their environmental impact. These simple changes can make a significant difference in water usage, especially when combined with other water-saving practices and improved wastewater treatment systems.

Limit the use of pesticides, herbicides, and fertilizers
China has been listed as one of 13 countries facing water shortages, and pollution exacerbates this scarcity. One of the main causes of water pollution in China is the discharge of agricultural hazardous pesticides and manure, which has contaminated both surface water and groundwater.
To limit the use of pesticides, herbicides, and fertilizers, several European countries, including Denmark, the Netherlands, and Sweden, introduced initiatives in the 1990s to reduce pesticide applications. For example, Denmark implemented a Pesticide Action Plan in 1986, aiming to reduce total pesticide applications by 50% in a decade. By 2004, Danish farmers had reduced pesticide inputs by 56% (kg of active ingredient) and 20% (treatment frequency index). This not only reduced impacts on biodiversity and groundwater resources but also had positive effects on invertebrates, plants, and farmland birds.
China has also taken critical actions to address water pollution. In 2015, the Chinese government issued the "Water Pollution and Control Action Plan" (known as Shuishitiao or Water Ten Plan), investing over 100 billion US dollars in national water pollution prevention and control work. The plan specifically targeted the elimination of black odor water in urban areas. Additionally, China has constructed a large number of municipal wastewater treatment plants (WWTPs) over the past two decades, significantly improving the collection and treatment of wastewater.
To further build on these efforts, China could consider implementing similar initiatives to reduce the use of pesticides, herbicides, and fertilizers. This could involve introducing regulations and incentives to promote more sustainable and environmentally friendly alternatives. For instance, providing subsidies or tax breaks for farmers who adopt integrated pest management practices or organic farming methods could help reduce the reliance on chemical inputs.
Additionally, public education and outreach campaigns can play a crucial role in raising awareness about the proper use and disposal of pesticides, herbicides, and fertilizers. By empowering individuals and communities with knowledge about the potential risks and impacts of these substances, they can make more informed decisions and contribute to collective efforts to protect water resources.

Encourage the use of drought-tolerant plants and grasses for landscaping
China has been facing a water shortage, with its water resources per capita being a quarter of the world's average level. The country has also been listed as one of 13 countries with a water shortage by the United Nations. Water pollution exacerbates water scarcity in China, with industrial wastewater, domestic sewage, agricultural hazardous pesticides, and manure polluting surface and groundwater.
To prevent water pollution in China, encouraging the use of drought-tolerant plants and grasses for landscaping is a viable option. Drought-tolerant landscaping is an attractive alternative to water-intensive lawns. Water-wise plants not only reduce maintenance but also use fewer resources. Ornamental grasses, for example, are drought-tolerant and require little supplemental water once established. Blue fescue, a type of ornamental grass, provides multi-seasonal interest with its evergreen foliage and elegant wheat-colored seed heads that last all summer. It is suitable for erosion control along slopes and can grow in dry shade areas.
Another example of a drought-tolerant plant is the black-eyed Susan, which is grown for its long-blooming daisy-like flowers in rich tones of gold, bronze, and brown. This plant is also deer-resistant due to its coarse-haired, green foliage. The Arizona Apricot blanket flower is another drought-tolerant option, with colorful flowers in bright hues of red, orange, coral, and yellow. This plant thrives in dry and sunny conditions and attracts bees and other pollinators.
Bugleweed is a drought-tolerant plant that can grow in a wide range of conditions and is combined with other drought-tolerant perennials such as ornamental grasses, yarrow, salvia, and lamb's ear. Cranesbill geranium is another option, which can be used for erosion control along slopes, as pathway edging, or in rock gardens.
'Beyond Blue' is a type of blue fescue that is even bluer than the much-loved 'Elijah's Blue'. This dwarf ornamental grass forms a dense mound of fine-textured, icy-blue foliage and is topped with feathery, wheaten bloom spikes in late spring and early summer. It is drought-tolerant, deer-resistant, and sun-loving, making it an excellent choice for any water-wise garden.
'Blonde Ambition' blue grama is a rugged, heat-, cold-, and drought-tolerant grass with semi-evergreen clumps of upright, fine-textured, blue-green foliage. It produces a profusion of golden blooms in the summer, which mature into soft blonde seed heads in the fall, providing year-round interest. This grass is low-maintenance, prefers full sun, and has very low water requirements once established.
