Understanding Water Treatment Chemicals

Water treatment chemicals play a vital role in protecting our nation’s drinking water supplies. These chemicals are critical to public health and safety, as they help remove drinking water contaminants and improve the overall quality of drinking water. By employing a variety of chemical compounds, these treatments ensure safe drinking water access and the reliability of our water sources.

What Are Water Treatment Chemicals

Regulated chemicals such as chlorine, ozone, and alum are used to treat the water. These multivalent compounds have a variety of functions, including disinfecting, coagulating, and filtering out impurities. Keeping up with water quality standards is very important since it prevents waterborne diseases and keeps the water within health regulations.

Chemical residues in treated water can be highly dangerous if not monitored carefully. This unfortunate circumstance highlights how desperately more constant monitoring and further study make their case.

Common Chemicals Used in Water Treatment

Chlorine is one of the most common disinfectants used in water treatment, and one of the most effective at killing bacteria and viruses. Ozone is an alternative powerful disinfectant that quickly oxidizes contaminants and removes pollutants from the water.

Alum functions as a coagulant, aggregating particles for easier removal. Though effective, the use of these chemicals can lead to adverse environmental impacts, requiring a delicate balance between protecting infrastructure and ecosystems.

Purpose of Using These Chemicals

The ultimate purpose of the water treatment chemicals we use is to protect public health. By keeping waterborne diseases at bay, these treatments ensure that every community has the opportunity to drink clean, safe water.

Meeting or exceeding standards imposed by regulating bodies such as the Environmental Protection Agency (EPA) keeps our water as safe as possible.

PFAS and Their Role

What Are PFAS

PFAS, or per- and polyfluoroalkyl substances, are a class of man-made chemicals. Their strong carbon-fluorine bonds serve to make PFAS incredibly persistent in the environment. This durability is what has made them so useful in everything from firefighting foams to non-stick pans.

That same persistence is a cause of concern. PFAS can accumulate in our drinking water. For one, substances like PFOA and PFOS, which are widely known PFAS, are part of the bloodwork of over 95% of the U.S. Population.

These health implications are dire, particularly concerning reproductive health. Women currently exposed to PFAS are already at risk for life-threatening health issues. These include reduced bone density and alterations to the menstrual cycle. Moreover, prenatal exposure can cause hypertensive pregnancy disorders.

How PFAS Are Used in Water Treatment

PFAS are used to create oil- and water-repellent properties, which provide useful features such as stain resistance. These benefits are not without their downside. PFAS don’t break down, leading to widespread contamination.

Water treatment plants can’t completely filter out these chemicals, allowing PFAS to continue to exist in treated water. This persistence poses unique challenges. Alarm bells should go off when high PFAS levels, like those detected in young girls in Cincinnati, are found.

PFAS Contamination Sources

While some PFAS are accidentally released by industries producing them, landfills and wastewater treatment plants play a notable role in PFAS dispersal. Runoff from agriculture spreads these chemicals even further.

Such widespread contamination is why PFAS, including PFNA and PFHxS, are found in nearly all Americans. This latter exposure has been associated with reproductive effects, including subfecundity and disrupted estrone and estradiol levels in females.

Reproductive Health Concerns

How PFAS Affect Reproductive Health

PFAS, or per- and polyfluoroalkyl substances, are commonly known for their negative reproductive health impacts, especially in women. These chemicals act as endocrine disruptors, mimicking or blocking hormones to cause hormonal imbalances.

These disruptions have a clear impact on fertility, with studies finding PFAS exposure associated with lower fertility rates and pregnancy complications. Pregnant women in the U.S. Are already exposed to a cocktail of environmental chemicals, and PFAS are an important part of that equation.

The resulting exposure can cause serious adverse outcomes including low birth weight and neurodevelopmental effects in fetuses. It’s important to know these risks, as thousands of chemicals are able to cross the placenta. This can often result in greater exposure to the fetus than to the mother.

Key Reproductive Health Concerns for Women

Women experience a number of serious reproductive health issues from PFAS exposure, such as hormonal disruptions and infertility. PFAS exposure has been linked to negative pregnancy outcomes such as low birth weight, affecting long-term health.

PFAS exposure has long term impacts on women’s reproductive health. This underscores the importance of education and prevention. For example, chemicals found at 106 military sites have a significantly greater negative impact on women of color, highlighting the intersections of environmental justice and reproductive health.

Long-Term Health Implications

Protecting health, including reproductive health, is essential. Beyond reproductive health, PFAS exposure is linked to chronic health problems, including cancer. Ongoing research further underscores the need to understand PFAS’s full health risks.

The effects of NA on various stages of neuronal development may have long-term developmental disturbances. These reproductive health concerns are consistent with nationwide issues, as systems serving smaller, often marginalized populations are responsible for the majority of health violations, pointing to infrastructure concerns.

Providing equitable access to clean, safe water, especially to our most vulnerable communities, is still one of our top goals.

Demographic and Reproductive Factors

Factors Influencing PFAS Exposure

Location and occupation have a large impact on PFAS exposure. Contaminants from manufacturing processes often end up in residents’ drinking water, leading to higher exposure among those who live near industrial areas. For instance, communities located around factories that use PFAS may have higher concentrations of PFAS in their drinking water.

Job roles in these industries may further exacerbate exposure. These environmental factors, such as proximity to contaminated water sources, are known to be major drivers. Dietary patterns, like regular intake of ultra-processed foods, can increase exposure.

Socioeconomic status plays a role in access to clean water, with lower-income households at greater risk. Fostering community awareness is key. Empowering residents with knowledge minimizes harmful exposure through the use of alternative water sources and through proactive filtration practices.

Demographic Variations in Exposure

Exposure levels are not the same across demographics. Race and gender can influence these variations. Environmental racism usually looks like minority communities having a higher risk of exposure because they live in regions where regulations are stricter for the white population.

This is a call to action for better, more equitable reproductive health policies to close these gaps. Women have reproductive health risks that are different from men. For example, exposure to endocrine disruptors like bisphenol A (BPA) is associated with problems including recurrent miscarriages.

Such disparities require focused interventions.

Physiological Effects Based on Demographics

Physiological differences influence PFAS toxicity. Age, sex, and health conditions are crucial in assessing exposure risks. For example, pregnant women excrete significant amounts of hormones, which PFAS can disrupt.

Tailored health interventions based on demographic data can help mitigate these risks.

Impact of Insufficient Regulations

Current Regulations on PFAS

According to federal standards, per- and polyfluoroalkyl substances (PFAS) are only regulated in drinking water at a national level as of 2023. Adequate and effective oversight by the Environmental Protection Agency (EPA) is essential in order to address harmful PFAS contamination. Yet the complexity and variety of PFAS compounds make it difficult to create regulations that are protective of human health.

Local and state governments manage the majority of the spending on water utilities. They often face financial and logistical obstacles when it comes to enforcement. Very small systems serving fewer than 500 people make up a substantial share of violations, illustrating challenges in enforcement.

Gaps in Regulatory Frameworks

We’ve blogged about the significant gaps that remain in current PFAS regulations. These gaps do not meet the full extent of PFAS contamination in our water supplies. Without effective regulation, PFAS contamination continues to threaten public health, with communities of color suffering greater exposure.

Especially older infrastructures, which are often riddled with lead pipes, increase these risks, emphasizing the need for stronger regulations now more than ever. Our sad history of using arsenic, lead, and other toxic heavy metals in pest control makes this point all the more necessary. Robust science-based regulation is imperative to keep our communities healthy and up to date with scientific advances.

Consequences of Weak Regulations

Weak PFAS regulations lead to unnecessary health risks, including harm to reproduction. Real-life examples from military installations show the deep, life-altering effects on communities. The quick environmental chemical build-up, like that of acetochlor, serve to underscore the need for reform.

Stronger national policies are critical for protecting Americans’ public health and for delivering safe drinking water to all Americans.

Contaminated Water Systems

How Water Systems Get Contaminated

Pathways for contamination of water systems are numerous and ever-increasing. Runoff from urban and rural areas frequently loads pollutants—such as harmful chemicals like PFAS—into water supplies. At the same time, leaks in aging pipes offer an easy entry point for contaminants.

In addition, industrial activities and agricultural practices have become the leading causes of water pollution, especially in freshwater systems. Factories release waste that can seep into groundwater, while fertilizers and pesticides used in farming wash into nearby streams and rivers, further deteriorating water quality.

Protecting our source water is more important than ever. It plays an important role in keeping toxic pollutants out of our supply chain, leading to cleaner, safer drinking water.

Impact on Local Communities

Injustice — Contaminated water systems adversely affect everyone. Economically, local communities are left to bear the cost of treating diseases associated with contaminated water. Socially, the lack of clean water makes day to day life impossible for all.

As always, marginalized communities feel the brunt of these issues, suffering the most from inequitable access to clean water. This is where community engagement becomes key in addressing these gaps and failures.

When local residents are included in the decision-making process, solutions are more likely to address the needs of the community in a thoughtful, focused way.

Case Studies of Affected Areas

Looking at individual cases helps to highlight the devastating consequences of PFAS contamination. Without it, for example, where PFAS levels are already over the EPA’s health advisory, people face increased dangers to their health.

Community-led initiatives have shown to be a more effective and equitable approach to tackling these challenges. Yet in other areas of the country, consistent activism by community members has led to calls for more robust regulations and infrastructure, leading to cleaner water supplies.

Addressing the Concerns

1. Implement Stronger Regulations

For the health of our communities, stronger regulations on PFAS are imperative. Advocating for these changes requires doing so in a way that is consistent with the most current science. So when policymakers are developing these rules, they need to put public health front and center.

Our current drinking water standards should cover known harmful toxins such as lead and nitrates. The EPA, along with state and local governments, must require utilities to frequently test for contaminants and make these results public. This level of transparency will help encourage increased accountability and ultimately make our water safer.

2. Improve Water Treatment Processes

Upgrading water treatment processes to more effectively remove PFAS can help mitigate this. Advanced treatment technologies, such as activated carbon filters, hold promise for removing contamination.

Investing in the infrastructure upgrades is key to restoring and providing safe water access. This is particularly urgent in communities with aging infrastructure. There, nonexistent or broken systems fail to deliver clean water even for the barest of necessities.

3. Educate the Public on Risks

Public education campaigns, including those initiated by local grassroots organizing, can help increase awareness of PFAS, water safety, and health. By informing communities about the health risks, these advocates are empowering people to fight for clean water.

Educational resources are an important part of this effort. They empower people to understand what safe water means and how to fight for it.

4. Promote Research on PFAS Alternatives

Given the serious risk posed by PFAS, research into PFAS alternatives is critical. Creating PFAS-free products and processes protects water from contamination.

Innovation in this space tackles larger water quality issues, providing long-term sustainable solutions for water quality in the future.
