Water And Wastewater: A Seemingly Abundant Resource

Water And Wastewater And Wastewater Is A Seemingly Abundant Resource O

Water and Waste Water and Waste Water is a seemingly abundant resource on the planet, but that perception would be incorrect. Although 70% of the Earth’s surface is covered by water, less than 1% of that is potable — fresh water that people can drink and water crops with. The rest is unusable with about 97% of it in the oceans, which are too salty for these purposes. The average American uses about 100 gallons of water per day, depending on how you calculate water usage. The majority of that water is used in the bathroom for bathing and flushing toilets.

In the United States, you can simply turn the faucet on when you need water, but others in many parts of the world are not so fortunate. Have you ever thought about where all of that water comes from or where it goes after it leaves your house? How do communities ensure that the water supply is safe? How do you ensure that the water you send down the drain does not harm the environment? Wastewater treatment processes are critical for addressing these questions. Wastewater, which is the water that goes down drains and toilets, is collected and treated through a series of processes to remove pollutants before being released back into the environment. Drinking water quality is maintained through regulation and treatment standards enforced by agencies such as the Environmental Protection Agency (EPA). However, recent concerns have risen over contaminants like pharmaceutical and personal care products (PPCPs) that can persist through traditional treatment methods.

Research has highlighted that pharmaceuticals and personal care products frequently appear in water supplies, raising questions about their ecological and human health effects. These substances often originate from human excretion, improper disposal, and runoff, and they are not routinely targeted in conventional water and wastewater treatment. The EPA's current treatment facilities do not specifically remove PPCPs, partly because these contaminants are emerging issues and require specialized detection and removal technologies.

In your posts this unit, answer the following questions: Why do we still need to conserve water even in regions with abundant rainfall? Why are drinking water and wastewater treatment facilities not currently equipped to handle pharmaceutical or personal care product pollutants? How should the country address these contaminants—through new treatment technologies or prevention strategies? Provide your insights with support from research and cite your sources.

Furthermore, review your local community’s water conservation policies and wastewater treatment practices by visiting your community, town, city, or state government website. Post one interesting fact you discover from your research. Later in the unit, compare your findings to those shared by a classmate, noting any similarities or differences in policies and approaches. Use the APA Quick Reference Guide for citations. Refer to the text by Trefil and Hazen (2013) for additional context on these topics.

Water and wastewater management are critical issues facing modern societies due to the fragile balance between water availability, quality, and environmental protection. Despite Earth's abundant water covering about 70% of its surface, only a minuscule portion—less than 1%—is suitable for human consumption, agriculture, and sanitation. This scarcity is exacerbated by pollution, overuse, and inadequate treatment infrastructure. Both water conservation efforts and advanced wastewater treatment are essential to ensure sustainable water resources for current and future generations.

One of the primary reasons for advocating water conservation—even in areas with high rainfall such as the Great Lakes region—is to preserve infrastructure capacity and reduce environmental stress. Excess water usage leads to increased energy consumption in treatment plants and can overwhelm wastewater systems, resulting in pollution and ecological imbalance. Additionally, conserving water reduces the volume of wastewater requiring treatment, thereby minimizing the burden on treatment facilities and reducing the risk of pollutant discharge, including emerging contaminants like pharmaceuticals and personal care products (PPCPs).

Current drinking water and wastewater treatment facilities typically do not address PPCPs effectively because these contaminants are relatively recent concerns in environmental science. Conventional treatment methods—such as primary clarification, biological treatment, and disinfection—are primarily designed to remove organic matter, nutrients, and pathogens. PPCPs, however, are often present at trace levels and are chemically diverse, making their removal more challenging. The cost and complexity of implementing new treatment technologies like activated carbon adsorption, advanced oxidation processes, or membrane filtration also pose significant barriers.

Addressing PPCP pollution requires a multifaceted approach. Prevention strategies, including public education on proper disposal of pharmaceuticals and encouraging the use of biodegradable personal care products, are crucial. Simultaneously, investment in innovative treatment technologies capable of removing trace contaminants should be prioritized. Implementing source control measures can significantly reduce the load of pharmaceuticals entering water systems, thereby decreasing the reliance on costly advanced treatment methods downstream.

At the local level, many communities have adopted policies encouraging water conservation, such as public awareness campaigns, water-efficient appliance incentives, and restrictions during drought conditions. For example, some cities in California promote xeriscaping—landscaping with drought-resistant plants—to minimize outdoor water use. Similarly, wastewater treatment plants are increasingly exploring advanced processes like ozonation and nanofiltration to address emerging contaminants. One interesting point I learned through research is that some wastewater facilities in the United States are beginning pilot programs incorporating reverse osmosis and other advanced technologies to target PPCPs directly (U.S. EPA, n.d.).

In comparing local policies nationwide, some regions emphasize source reduction and conservation, while others focus on technological upgrades for treatment plants. While the core goal remains safeguarding water quality, the approaches differ based on regional geography, economic capacity, and policy priorities. Understanding these variations highlights the importance of tailored solutions that fit local needs while aligning with national environmental principles.
