Are PFAS Forever Chemicals In Your Tampa Drinking Water?
PFAS “Forever Chemicals” are in Tampa water. The question is, how much, and is it too much? The current results of the EPA study show results that border the current proposed maximum contaminant levels for regulatory standards.
The Environmental Protection Agency (EPA), in conjunction with the state of Florida, has taken steps towards regulating PFAS in drinking water. In March 2023, the EPA proposed Maximum Contaminant Levels of 4 parts per trillion (ppt) for PFOA and PFOS. Finalized contaminant Levels are expected by the end of 2023. You can view the EPA’s proposed action for PFAS here. The proposed action levels are on slide 14.
EPA’s ongoing efforts under the Unregulated Contaminant Monitoring Rule (UCMR) involve collecting data for unregulated contaminants suspected in drinking water. This data aids in regulating such contaminants. The fifth UCMR phase (UCMR 5) requires sampling for 30 chemical contaminants, including PFAS, between 2023 and 2025.
Tampa Bay Water and its member utilities are actively participating in EPA’s UCMR 5 study, focusing on PFAS concentrations in treated drinking water. This collaboration aids EPA in setting PFAS regulations, with testing commencing in July 2023 for Tampa Bay Water and its members, and January 2023 for the City of Tampa.
The results of the testing are presented by the delivery point sampled, its member utility served and the six PFAS which the EPA has set a proposed Maximum Contaminant Level of 4 ppt. The first quarter’s results are as follows:
PFOA: 2.70 ppt
PFOS: 4.30 ppt
PFBS: 5.00 ppt
PFHHxS: 2.40 ppt
PFNA: 0.80 ppt
HFPA-DA: Non-detectable levels found
The most recent results of the UCMR study can be found here, measured in parts per trillion. You can use tools such as XConvert to take the number and see it as ppb. Notice that not all chemical types are listed here or in the study.
For reference, a part per trillion (ppt) is roughly equivalent to a single drop of water in 20 Olympic-sized swimming pools or one second in 32,000 years. These updated interim Health Advisory Levels are below the detection capabilities of current laboratory testing technology. They serve as interim guidance until formal regulations or Maximum Contaminant Levels are established.

Why Is My Tampa Water Contaminated With PFAS Forever Chemicals?
When it comes to PFAS-contaminated water, the situation can be particularly relevant to residents of Tampa, Florida, especially those serviced by Culligan. Certain areas are more susceptible to elevated levels of PFAS due to historical usage of these chemicals in various industrial and commercial activities. Tampa, being a vibrant city with diverse zones of activity, might experience varying degrees of PFAS contamination in its water sources.
Living near specific sites, such as airports or firefighter training facilities, could put residents at a higher risk of encountering water with elevated PFAS concentrations. These sites historically utilized PFAS-containing foams for firefighting exercises and emergency response drills, which could have seeped into the ground and eventually reached the water supply. As such, individuals residing near these locations might be concerned about the levels of PFAS in their tap water.
Manufacturing centers in Tampa are another area of focus when it comes to PFAS contamination. With its economic diversity, the city may have a history of manufacturing activities related to carpet production, food packaging, and various consumer goods. PFAS were commonly used in these processes due to their unique chemical properties. Over time, these chemicals might have entered the local water sources, potentially leading to higher concentrations in certain areas. This situation is particularly important to Culligan of Tampa, as a water treatment and purification company, to address potential PFAS-related concerns in their service areas.
For residents of Tampa, understanding the actual levels of PFAS in their water is crucial. Culligan, with its expertise in water treatment and purification, is well-positioned to provide essential information and potential solutions.
Further Explanation On What “Forever Chemicals” Are
PFAS, commonly known as ‘Forever Chemicals,’ water contamination impacts residents in many places across the United States, including the Tampa Bay area. The problem with PFAS and similar contaminants is that, until recently, few people knew or understood them. Compounding this issue, PFAS have become nearly ubiquitous in our environment.
It started in the early 1940s, when water and heat-resistant chemicals containing per- and polyfluoroalkyl substances were engineered to help create non-stick products (Teflon), fire retardants, and other common consumer goods. What wasn’t understood at the time, however, was that Teflon and other products using PFAS wouldn’t naturally decay in nature–or the human body.
Known as bioaccumulation, this chemical characteristic means any amount absorbed in our bodies – through eating or drinking – stays in our bodies. Since we have no way of removing or disposing of these chemicals, they’ve earned the ominous nickname, ‘forever chemicals.’ As a result, most PFAS have been phased out of use in this country. But they remain prevalent in the environment, and this includes our water supply.
What About PFOA? Where Are They Found?
PFOA, the most notable substance of the PFAS family, was found to be a part of the manufacturing process of Teflon. The EPA sued DuPont in 2005 for failing to report a health risk to both humans and the environment. The company paid a $10.25 million settlement.
Because of PFOA and PFAS strong molecular structure, they take much longer to break down naturally than other organic chemicals.
Until 2002, PFOA were integral in producing goods which qualities repel dirt, grease, water and stains.
These contaminants can be found in the manufacturing process of a variety of products, including non-stick cookware, carpet-care liquids, treated apparel, upholstery or textiles, sealants, dental floss, floor wax and non-woven medical garments. Though PFTE non-stick cookware was proven to have PFOA levels, a recent study found levels that ranged from undetectable to 4.3 parts per billion, and it is not currently considered a major pathway for PFOA.
Just last year, United Nations experts recommended banning PFOA globally at the Stockholm Convention on Persistent Organic Pollutants. Will the United States follow suit based on recent outbreaks in Texas and Michigan.
Problems with PFOA
According to a study from 2002-2005, people who lived in the PFOA-contaminated area around DuPont’s Washington Works facility were found to have higher levels of PFOA in their blood from drinking water. People that drank more tap water, ate locally grown fruits and vegetables, or ate local meat, were all associated with having higher PFOA levels.
Residents who used carbon filter systems had lower PFOA levels.” Studies have found that using carbon-activated filters can reduce PFOA by up to 60%.
PFAS Connection To Testicular Cancer
A government funded report published by the National Academies of Sciences, Engineering and Medicine found strong evidence that being exposed to PFAS could lead to health issues like weaker vaccine responses, kidney cancer, and underweight newborns. They suggested that areas with high PFAS exposure should do blood tests and health checkups for people with significant exposure. The report also noted a probable link, though with less certainty, between PFAS exposure and thyroid issues, pregnancy-related preeclampsia, and certain types of cancers.
A recent study focusing on Air Force service members was release in July of this year. This study went even further, directly connecting PFAS exposure to a specific type of testicular cancer that makes up around 95% of cases.
Testicular cancer is the most common cancer among young adult men. Among those in the military, especially men aged 18 to 40, are the most frequently diagnosed cancer. To prove this connection, researchers used samples from over 62 million service members’ blood collected between 1988 and 2017. They looked at samples from 530 troops who later got testicular cancer and 530 who did not. A second round of sampling four years later showed that higher levels of PFAS were linked to a higher risk of testicular cancer.
Popular Brands Contaminated with PFAS Forever Chemicals
According to the Agency for Toxic Substances and Disease Registry, PFAS, known for their oil and water resistance, non-stick, and fire-resistant qualities, are commonly added to various everyday products used by most Americans such as the following:
- Food packaging: take out containers, food wrappers
- Non-stick pans (Teflon)
- Carpets, rugs, furniture textiles, window treatments, car seats
- Stain and waterproof clothing
- Outdoor gear
- Dental Floss
- Microwaveable popcorn bags
- Firefighting foam and personal protective gear
- And more.
Simply Orange Juice PFAS Contamination
A class action lawsuit alleges Simply Tropical and Simply Orange beverages have been promoted as “All Natural” and made with “all-natural ingredients.” Nevertheless, the lawsuit contends that lab tests conducted on Simply Tropical contradict these claims, revealing the presence of PFAS, artificial chemicals that are not natural.
PFAS Contamination In Lululemon
An analysis by Toxic-Free Future tested 60 items from various categories, discovering that 35 products, mostly leggings and yoga pants, had fluorine levels exceeding 100 parts per million, a strong PFAS indicator. Among the brands tested were Lululemon and Old Navy. Of these, three-quarters contained banned long-chain PFAS compounds. Notably, 28% of the tested products contained PFAS, with 34 out of 47 items with water-resistance claims showing PFAS presence. An additional investigation also found PFAS in popular sportswear brands, raising questions about long-term exposure risks associated with PFAS-coated clothing.
Forever Chemicals in Menstrual Products
The Thinx underwear brand was involved in a lawsuit alleging their products contained PFAS after the marketed their products as a safe, sustainable product, free of harmful chemicals. The period underwear company has settled a lawsuit regarding allegations of inadequate product effectiveness and misleading advertising.
PFAS In Sparkling Water
According to Green Matters, Consumer Reports detailed the levels of PFAS found in many popular carbonated water brands contain. Topo Chico, owned by Coca-Cola Co., was an extreme outlier containing 9.76 parts per trillion. Most brands tested were only slightly above 1 part per trillion, with Poland Spring at 1.66, Canada Dry at 1.24, LaCroix at 1.16 and Perrier at 1.1. As for non-carbonated water, Deer Park tested at 1.21 parts per trillion.
Recommendations by the EPA For PFAS Forever Chemicals
The EPA holds the responsibility of overseeing the regulation of drinking water standards. While PFAS regulation in drinking water has not yet been established by the EPA, they have outlined suggested Maximum Contaminant Levels of 4 parts per trillion (ppt) for PFOA and PFOS. The EPA is anticipated to unveil the final regulations for PFOA and PFOS by the conclusion of 2023.
To put this into perspective, comprehending the scale of a part per trillion is essential. Picture one ppt as a single droplet of water dispersed across 20 vast Olympic-sized swimming pools or one second in 32,000 years.
