And How To Mitigate This Insidious Problem
Water is a fundamental resource for all living beings, and access to clean drinking water is crucial for maintaining good health. However, drinking water pollution is a growing concern in the United States. This article aims to shed light on the current pollution levels, identify the sources of contamination, and discuss practical strategies to mitigate the problem.
The Importance of Clean Drinking Water
Clean drinking water is essential for maintaining hydration, supporting bodily functions, and preventing waterborne diseases. It plays a vital role in the overall well-being of individuals and communities. However, the pollution of water sources poses a significant threat to the availability of safe and clean drinking water.
Current Drinking Water Pollution Levels in the United States
Drinking water pollution is a pressing issue in the United States. Although we’ve made significant progress in water treatment and regulation, there are still areas where pollution levels exceed acceptable limits. The Environmental Protection Agency (EPA) monitors water quality across the country and identifies contaminants that pose risks to human health.
Sources of Drinking Water Contamination
Several sources contribute to the contamination of drinking water in the United States. Understanding these sources is crucial for devising effective strategies to address the issue.
Perfluoroalkyl and Polyfluoroalkyl Substances (PFASs)
The United States faces a significant issue with perfluoroalkyl and polyfluoroalkyl substances (PFASs), commonly known as “forever chemicals,” in drinking water (2). These chemicals remain long-term in the environment and accumulate in the human body, leading to various health problems. While some states have taken measures to address this concern, there are currently no federal regulations on the concentration of PFASs in water. PFASs are found in many products and have become widespread in soil, surface water, the atmosphere, and human bodies. A study estimated that over 200 million Americans, most of the population, have tap water contaminated with a mixture of specific PFAS compounds (at concentration levels of one part per trillion (ppt) or higher).
Research has linked PFAS exposure to cancer, thyroid disease, liver damage, developmental toxicity, high cholesterol, immune dysfunction, and other health issues (3). Although technologies exist to remove PFASs from drinking water, they are expensive and require ongoing maintenance. The financial burden of implementing these technologies falls primarily on taxpayers. Moreover, removing PFASs from drinking water may result in their accumulation in other areas. While some states have taken action, experts emphasize the need for federal regulations to address this widespread problem.
PFASs are used in numerous products, including firefighting foam, cookware, cosmetics, and carpet treatments. Due to their extensive use and improper disposal, these chemicals have become ubiquitous in soil, surface water, the atmosphere, and even the human body. The Centers for Disease Control and Prevention (CDC) found PFASs in nearly everyone tested’s blood, indicating widespread exposure (4).
Industries can release pollutants into water bodies through improper waste disposal or accidental spills. Chemicals, heavy metals, and other toxic substances can contaminate water sources, making them unsafe for consumption.
Agricultural activities, such as excessive use of fertilizers and pesticides, contribute to water pollution. When it rains, these chemicals can wash off the fields and find their way into rivers, lakes, and groundwater, posing a risk to drinking water supplies.
Chemical spills, whether accidental or intentional, can have severe consequences for water quality. Hazardous substances can infiltrate water sources and have detrimental effects on both human health and the environment.
The infrastructure for delivering clean water to homes and businesses is aging in many parts of the United States. Outdated pipes and systems can contaminate the water supply, compromising its quality.
Various Impacts of Drinking Water Pollution on Human Health
Drinking water contaminated with pollutants can lead to various health issues, ranging from gastrointestinal problems to long-term illnesses. Consuming water with high levels of contaminants like bacteria, viruses, heavy metals, or chemicals can have severe implications for human health, particularly for vulnerable populations such as children, pregnant women, and aging adults.
For example, research indicates that the development of Autism spectrum disorders (ASD) is affected by both genetic abnormalities and environmental toxicants. Some toxicants linked to ASD include pesticides, phthalates, polychlorinated biphenyls (PCBs), solvents, toxic waste sites, and air pollutants. The strongest connections involve air pollutants and pesticides. A systematic review of studies on the connection indicates that the cause of ASD seems to be a combination of genetic factors and specific environmental toxicants that interact during crucial times in brain development, increasing ASD risk (5).
5 Ways to Mitigate Drinking Water Pollution
Addressing drinking water pollution requires a multifaceted approach involving government, communities, and individuals. Here are some strategies that can help mitigate the problem:
- Strengthening Regulations and Enforcement: Enhancing and strictly enforcing regulations related to water pollution is crucial. This includes setting strict limits on pollutants, monitoring compliance, and implementing penalties for violations. Regular inspections of industrial facilities and agricultural practices can ensure adherence to these regulations.
- Investing in Infrastructure Upgrades: Upgrading and maintaining water infrastructure is essential for ensuring clean drinking water. Replacing old pipes, improving treatment plants, and implementing advanced filtration technologies can help reduce the risk of contamination.
- Promoting Sustainable Agriculture Practices: Encouraging sustainable agricultural practices, such as organic farming and precision nutrient management, can minimize the use of harmful chemicals and reduce agricultural runoff. Additionally, promoting the use of alternative methods for pest control can contribute to cleaner water sources.
- Raising Awareness and Community Involvement: Educating the public about the importance of clean water and the impact of pollution is crucial. Increasing awareness can empower individuals to take action, such as participating in local clean-up initiatives, supporting organizations working on water conservation, and advocating for stronger environmental regulations.
- Supporting Organizations that Produce Sustainable, Green Products: Volunteer, donate, invest, and buy products from organizations dedicated to addressing planet health regarding climate change, landfill waste, soil health, and clean water and air.

The Role of Individuals in Mitigating Drinking Water Pollution
Individuals also have a significant role to play in mitigating drinking water pollution. Some actions individuals can take include conserving water, properly disposing of hazardous materials, reducing single-use plastics use, and supporting environmentally responsible businesses.
