What Cities Have PFAS in Drinking Water?
Across the Sunshine State, there have been several reported instances of per- and polyfluoroalkyl substances, commonly known as forever chemicals, contaminating the drinking water. These synthetic chemicals, associated with a myriad of potential health effects, have been found in the tap water of numerous cities. Particularly in South Florida, cities such as Delray Beach have seen high concentrations of PFAS, with levels significantly exceeding the EPA’s lifetime health advisory (LHA).
From the data gathered in the last week of April, 2022, here are some of the cities in South Florida with the notable presence of PFAS in their drinking water:
- Delray Beach: PFAS levels 8,225 times higher than the EPA’s LHA.
- Other unnamed cities: High levels of PFAS but specific concentrations not provided.
- Highland Beach: No detected levels of PFAS.
It’s important to note that these results were obtained using Cyclopure test kits, developed under a grant from the National Institute of Environmental Health Sciences (NIEHS), offering a convenient, accurate, and affordable method for PFAS testing.
What Is Florida Doing About PFAS Contamination?
While there have been significant strides made in acknowledging the issue, Florida’s response to the PFAS contamination is still being met with criticism. Reports suggest that the state, through the Florida Department of Health, has been providing somewhat controversial and potentially misleading information about the health risks associated with PFAS. The state’s approach has been deemed by some as a disservice to public health.
From the water contamination in Delray Beach to the divergent scenario in Highland Beach, it is evident that more definitive actions are needed to combat PFAS contamination in Florida’s drinking water effectively. The article will delve deeper into this issue, exploring the nature of PFAS, their health effects, existing standards, and what individuals can do to ensure their water is safe.
Overview of PFAS
What are PFAS?
Per- and polyfluoroalkyl substances, or PFAS, are a large group of human-made chemicals that have been used in many industries around the world since the 1940s. Known for their resistance to heat, water, and oil, these chemicals are found in a wide range of consumer and industrial products. Here are a few examples of where PFAS can be found:
- Non-stick cookware
- Water-repellent clothing
- Stain resistant fabrics and carpets
- Some cosmetics
- Products that resist grease, water, and oil
- Firefighting foams
Two of the most extensively produced and studied PFAS are PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate). Although these specific types of PFAS are no longer manufactured in the United States, they are still produced internationally and can be imported into the country in consumer goods.
How Do PFAS Get into Drinking Water?
PFAS can enter the environment in various ways, mainly through industrial processes that make or use these chemicals. They can also come from consumer products and the use of firefighting foam. Once in the environment, PFAS are incredibly persistent, meaning they don’t break down and can accumulate over time.
Given their persistence and mobility, PFAS can easily contaminate groundwater and surface water, subsequently making their way into drinking water supplies. Here are some key sources of PFAS in drinking water:
- Industrial releases: Factories that produce or use PFAS can release these chemicals into the air, soil, and water.
- Landfills: Discarded products containing PFAS can break down over time in landfills, leaching these chemicals into the soil and potentially groundwater.
- Firefighting foams: PFAS-based foams are often used to fight fuel fires. Use of these foams can result in contamination of soil and water.
- Wastewater treatment plants: These facilities may discharge PFAS into the environment, or the PFAS-laden sludge may be used as a soil amendment.
Health Effects of PFAS
PFAS are sometimes referred to as “forever chemicals” because they can stay in the human body for a long time, accumulating over time. The potential health implications of PFAS exposure have become an area of increasing concern.
According to WebMD, here are some of the health effects associated with exposure to high levels of PFAS:
- Increased risk of certain cancers, including kidney and testicular cancers
- Effects on the immune system
- Interference with the body’s natural hormones
- Increased cholesterol levels
- Potential adverse effects on fetal and child development
- Reduced fertility in women
These potential health impacts emphasize the need for vigilance in monitoring PFAS levels in our environment and working to reduce exposures. The next sections will explore the existing standards for PFAS in drinking water and what steps you can take to ensure your water is safe.
PFAS Drinking Water Standards
Understanding the standards set for the levels of contaminants in our drinking water, like PFAS, is crucial. These standards reflect the collective agreement on the amount of a potentially harmful substance we can consume without harm. They give us insight into how safe or risky our water and food might be.
What is the Standard for PFAS in Drinking Water in Florida?
Florida, like many states, refers to the federal guidelines for PFAS levels in drinking water. However, these guidelines are not enforceable regulations. As of now, the Florida Department of Environmental Protection (DEP) does not have a specific maximum contaminant level (MCL) for PFAS in drinking water.
Instead, they have established screening levels for two PFAS compounds, PFOA and PFOS. The screening levels serve as guidelines to determine if contamination may pose a risk to human health. They are not binding limits, but they provide a benchmark for decision-making. For PFAS, the screening levels set by Florida DEP are as follows:
| Compound | Screening Level |
| PFOA | 70 parts per trillion (ppt) |
| PFOS | 70 parts per trillion (ppt) |
If PFAS levels exceed these screening values, the Florida DEP recommends further evaluation and potential action.
What is the EPA Drinking Water Standard for PFAS?
The Environmental Protection Agency (EPA) currently does not enforce a federal Maximum Contaminant Level (MCL) for PFAS in drinking water. However, the EPA has issued a health advisory level for two PFAS compounds, PFOA and PFOS. This advisory level is set at 70 parts per trillion (ppt), either for PFOA and PFOS individually or combined.
The health advisory level provides information about the concentration of a contaminant in drinking water at or below which adverse health effects are not expected to occur over a lifetime of exposure. This is not a legally enforceable standard, but a guideline to help public health officials and water systems manage potential risks from these chemicals.

Drinking water standards play an essential role in guiding our understanding and management of contaminants in our water supply. It’s important to remember that while standards help ensure the safety of our drinking water, we all have a role to play in remaining informed and proactive about potential threats to our water quality.
What Can I Do About PFAS?
The good news is that there are numerous actions we can take to safeguard ourselves and our loved ones from these potentially harmful “forever chemicals.” Let’s explore three of the most effective strategies.
PFAS Treatment Methods for Homeowners
If you’re concerned about PFAS in your drinking water, there are several in-home treatment methods that can help reduce or remove these contaminants. Here are some of the most effective options:
- Activated Carbon Filters: These filters are usually installed under the sink or at the point of entry into the home. They can effectively reduce PFAS levels, especially shorter-chain PFAS compounds.
- Reverse Osmosis (RO) Systems: RO systems use a semipermeable membrane to remove contaminants, including PFAS. They can be more effective than activated carbon filters for removing longer-chain PFAS compounds.
- Anion Exchange (AIX) Systems: These systems can also remove PFAS, but they may not be as effective for shorter-chain compounds.
Each method has its pros and cons, so it’s important to consider your specific needs and circumstances when choosing a treatment method. The following table provides a brief comparison of these three treatment options:
| Treatment Method | Pros | Cons |
| Activated Carbon Filters | Affordable, Easy to install, Effective for shorter-chain PFAS | Less effective for longer-chain PFAS |
| Reverse Osmosis Systems | Very effective, Can remove longer-chain PFAS | More expensive, Requires more maintenance |
| Anion Exchange Systems | Effective for a wide range of PFAS | Not as effective for shorter-chain PFAS, May require more maintenance |
How to Test for PFAS
If you suspect that your water may be contaminated with PFAS, the first step is to get it tested. Many companies offer testing services, and some states also have programs that provide free testing for residents. When choosing a testing service, ensure that they can test for a wide range of PFAS compounds, not just PFOA and PFOS.
