Travis Mast • October 27, 2025

🌊 Tune in to our latest podcast on tackling PFOS & PFOA in Dubuque & Platteville water! 🎙️ Discover life-changing solutions with Mast Water Technologies! 💧✨ #CleanWater #PodcastAlert #WaterSafety

In the heart of the Midwest, where the Mississippi River shapes the landscape and livelihoods of communities like Dubuque, IA, and nearby Platteville, WI, access to clean drinking water is more than a convenience—it's a necessity. Yet, recent concerns about "forever chemicals" like PFOS (perfluorooctanesulfonic acid) and PFOA (perfluorooctanoic acid) have raised alarms for residents relying on local wells and municipal supplies. These persistent pollutants, part of the broader PFAS family, don't break down easily and can accumulate in water sources, posing potential health risks over time. If you're searching for "PFOS in Dubuque water" or "PFOA health risks IA," you're not alone—thousands of locals are taking proactive steps to protect their families. At Mast Water Technologies, serving Platteville, WI, Dubuque, IA, and surrounding areas, we're committed to providing effective solutions like reverse osmosis systems to safeguard your home's water quality.


This guide breaks down what PFOS and PFOA are, the health concerns they raise, the latest 2025 reports highlighting elevated levels in our region, and practical tips for testing and treatment. With EPA regulations affirming strict limits, now is the time to act—don't wait for contamination to impact your well-being.


What Are PFOS and PFOA? The Basics of These "Forever Chemicals"


PFOS and PFOA are synthetic compounds developed in the mid-20th century for their water- and stain-repellent properties. PFOS was a key ingredient in products like Scotchgard, while PFOA powered nonstick coatings such as Teflon. Though phased out in the U.S. since the early 2000s, these chemicals linger in the environment due to their unbreakable carbon-fluorine bonds—earning them the nickname "forever chemicals."


These pollutants enter water systems through industrial runoff, firefighting foams, and even consumer products that degrade over time. In areas like Dubuque and Platteville, where groundwater and the Mississippi River feed local supplies, PFOS and PFOA can seep into shallow wells, contaminating drinking sources. According to the EPA, about 20% of lifetime PFAS exposure comes from drinking water, making it a critical pathway for residents in our region.


Why does this matter locally? Dubuque's shallow wells along the river, which supply much of the city's water, have tested positive for these compounds, while Platteville's rural wells face similar risks from agricultural and historical industrial activities. Understanding these chemicals is the first step toward cleaner water.


The Health Risks of PFOS and PFOA: From Cancer Links to Immune System Impacts


Exposure to PFOS and PFOA isn't just an environmental issue—it's a public health one. The International Agency for Research on Cancer (IARC) classifies PFOA as "carcinogenic to humans" (Group 1), based on sufficient evidence from animal studies and strong mechanistic data in humans showing epigenetic alterations and immunosuppression. PFOS earns a "possibly carcinogenic" rating (Group 2B), with limited evidence in animals and humans but robust signs of immune disruption.


Key health risks include:


  • Cancer Connections: PFOA is linked to kidney, testicular, and prostate cancers, with epidemiological studies showing increased incidence in exposed populations. PFOS may contribute to hormone receptor-positive breast cancers in postmenopausal women. For "PFOA health risks IA" searches, these ties are especially relevant, as Midwest communities report higher exposure from legacy pollution.
  • Immune System Suppression: Both chemicals impair the body's defenses, reducing vaccine efficacy and increasing infection risks. Studies show PFOS and PFOA alter white blood cell activity and antibody production, potentially worsening autoimmune conditions.
  • Other Effects: Elevated cholesterol, liver enzyme changes, thyroid issues, and developmental delays in children round out the concerns. Low-level, long-term exposure—like from daily tap water—amplifies these risks, particularly for vulnerable groups in Dubuque and Platteville families.


The EPA estimates no safe level exists for PFOA or PFOS, underscoring why treatment is non-negotiable.


Recent 2025 Dubuque Reports: Levels Exceeding EPA Limits—and What It Means for Platteville & Dubuque Area Residents


In 2025, Dubuque's annual water quality report revealed PFOS levels hitting 4.2 parts per trillion (ppt) in May tests—exceeding the EPA's 4 ppt Maximum Contaminant Level (MCL) for both PFOA and PFOS. While winter tests dipped below 3 ppt due to reduced reliance on contaminated shallow wells, summer spikes highlight seasonal vulnerabilities tied to the Mississippi River. The city plans $15 million in upgrades, including a new deep well, but residents aren't waiting—demand for home filtration is surging.


Across the river in Platteville, WI, the picture is equally concerning. Wisconsin's Department of Natural Resources (DNR) enforces a 70 ppt standard for PFOA and PFOS in drinking water, but 2025 EPA data flags regional groundwater hotspots near the Platte River. The state's PFAS Action Plan, mirroring Iowa's, shows elevated detections in rural wells, with average total PFAS in contaminated groundwater at 43.9 ng/L (nanograms per liter, or ppt). Platteville's proximity to Dubuque amplifies shared risks from cross-border pollution.


EPA's May 2025 announcement retained the 4 ppt MCLs but extended compliance to 2031, giving systems time while urging immediate action for high-exposure areas like ours. For locals, this means testing now to stay ahead of potential mandates.


Effective Treatment: Proven Solutions for PFOS and PFOA Removal in Your Home


When it comes to removing PFOS and PFOA, not all treatments are equal. Granular activated carbon (GAC) works well for long-chain PFAS but falters on shorter variants. At Mast Water Technologies, we offer cutting-edge options like reverse osmosis (RO)—the gold standard endorsed by the EPA for up to 99% removal of these chemicals. Our RO systems push water through a semi-permeable membrane under pressure, trapping PFOS and PFOA in a concentrate stream while delivering pure permeate. Certified to NSF/ANSI 58 standards, these units reduce contaminants to below detectable levels (as low as 2 ppt in pilots). Ideal for Dubuque homes with river-sourced water or Platteville wells, our whole-house and under-sink options include multi-stage filtration for comprehensive protection.


For even more targeted PFAS removal, Mast proudly integrates the Pioneer filtration system by EnPress LLC—a revolutionary whole-house (point-of-entry) solution designed specifically for forever chemicals. The Pioneer Lead & Chemical Filter system features proprietary ATOMUS® media in a 0.5-micron carbon block cartridge (CT-05-CB-AMYCL), engineered for molecular selectivity against both long- and short-chain PFAS like PFOA, PFOS, PFHpA, PFNA, PFHxS, PFBS, GENX, and PFDA. Independently tested and third-party certified to NSF/ANSI P473 for PFOA/PFOS reduction (97.9% removal) and NSF/ANSI 53 for lead (99.62%) and cyst (>99.95%) reduction, it outperforms traditional GAC or ion exchange resins with over 25x adsorption capacity, resistance to fouling, and no backwash required—making it perfect for the variable water chemistry in Dubuque and Platteville.


Key benefits of the EnPress Pioneer Lead & Chemical Filter system include:


  • Superior PFAS Removal: Achieves non-detect levels (<1 ng/L or ppt) for up to eight PFAS compounds, even at influent levels of 3,000+ ppt, treating over 168,000 gallons per cartridge at 7 gpm with 99.9% reduction.
  • User-Friendly Design: Low pressure drop, high flow rates (up to 10 gpm), and a compact 8" x 40" non-metallic housing in the EnPress ONE E3-M® series—ideal for residential and light commercial use without hazardous waste or bulky media changes. Meter-equipped with green/yellow/red indicator lights for easy cartridge replacement.
  • Additional Protection: Also removes soluble and particulate lead, chlorine (>300,000 gallons at 15 gpm with 90% reduction), chloramine (>150,000 gallons at 8 gpm with 85% reduction), arsenic, heavy metals, and chemicals, providing all-in-one filtration for Midwest water challenges.
  • Eco-Conscious: Exhausted cartridges are PFAS-free for safe disposal or recycling via EnPress's extraction program, minimizing environmental impact.


Local Expertise: Installed by our Platteville and Dubuque pros, the Pioneer pairs seamlessly with pre-filtration for iron or sediments common in regional wells. With cartridge life up to 100,000+ gallons for PFAS and lead, it's a cost-effective, long-term investment. Contact Mast today for a customized Pioneer setup—complete with free water analysis.


Tips for Testing Local Wells: Simple Steps for Dubuque and Platteville Residents


Private wells in our area demand vigilance, as they're unregulated like municipal systems. Here's how to test for PFOS and PFOA:


  • Gather Supplies: Use lab-provided PFAS-free bottles to avoid contamination—wash hands thoroughly first.
  • Collect the Sample: Run cold water for 5-10 minutes, then fill without rinsing the bottle. For wells, sample post-pump to capture raw groundwater.
  • Choose a Lab: In Iowa, contact the DNR or certified labs like those in the PFAS Action Plan; in Wisconsin, the State Laboratory of Hygiene offers EPA Method 1633A testing (required since Feb. 2025). Costs range $200-500 for 6-14 PFAS compounds.
  • Interpret Results: Aim below 4 ppt per EPA MCLs. If elevated, Mast offers free follow-up consultations to recommend systems like Pioneer or RO.
  • Frequency: Test annually or after floods/heavy rain, common in our region.


Early detection empowers action—many Platteville and Dubuque well owners have caught issues early with these steps.

By Travis Mast • November 30, 2025
As the leaves turn vibrant shades of red and gold in Platteville, WI, and the crisp autumn air sweeps through Dubuque, IA, we all know what's coming next: the chill of winter. Shorter days, frosty mornings, and that inevitable pile of snow waiting to be shoveled. But here's the good news—there's a simple way to turn those cold months into a season of pure bliss and self-care. At Mast Water, we're passionate about helping our neighbors in the Platteville and Dubuque areas embrace the colder weather with open arms (and warm jets). Enter the Bullfrog Hot Tub: your personal oasis of heat, relaxation, and health benefits right in your backyard. Whether you're winding down after a day at the office or recovering from a weekend of holiday prep, a Bullfrog Hot Tub isn't just a luxury—it's a game-changer for fall and winter living. Let's dive into the top reasons why installing one now will make you wonder how you ever survived the seasons without it. 1. Beat the Chill with Instant Warmth and Stress Relief Nothing says "welcome home" like slipping into 100-degree water after battling blustery winds. Fall and winter in Wisconsin and Iowa can be unforgiving, but a Bullfrog Hot Tub provides an immediate escape. The powerful jets, enhanced by Bullfrog's exclusive JetPak Therapy System®, deliver a full-body massage that melts away tension from your shoulders to your toes. With up to 17 interchangeable JetPaks®, you can customize your soak—choose the soothing Fusion Air® JetPak for ultra-light bubbles that feel like a gentle winter breeze, or the powerful DeepRelief® for targeted muscle unwinding. Picture this: It's a chilly November evening in Platteville, and you've just raked the last of the leaves. You fire up your Bullfrog, add a splash of essential oils, and let the hydrotherapy work its magic. Studies show that warm water immersion can lower cortisol levels (that's the stress hormone) by up to 30%, helping you unwind faster than a cup of chamomile tea ever could. In Dubuque's river town vibe, where the Mississippi's chill seeps in early, this ritual becomes your nightly reset button, amplified by the QuietDrive™ Technology that keeps operation whisper-quiet, so you can relax without disturbing the peaceful winter night. 2. Soothe Aches and Pains from Winter Woes Shoveling driveways, slipping on icy sidewalks, or just huddling against the cold—winter takes a toll on your body. Bullfrog Hot Tubs are designed with customizable JetPaks®, letting you target sore spots with precision. Those lower back twinges from hauling firewood? Gone with the Alleviate® JetPak. Stiff joints from the humidity drop? Eased in minutes by the FibroTherapy® option, which combines targeted jets with Bullfrog's innovative Fusion Air® System for a softer, more enveloping massage that reduces inflammation without overwhelming pressure. Hydrotherapy in a hot tub boosts blood circulation, delivering oxygen-rich blood to muscles and reducing inflammation—perfect for faster recovery after winter hikes or holiday shopping marathons. It's like having a personal physical therapist on call, 24/7. For active folks in our surrounding areas—like farmers wrapping up harvest or outdoor enthusiasts gearing up for cross-country skiing—a Bullfrog keeps you moving comfortably through the season. Bonus: The FDA even recognizes water therapy for alleviating arthritis symptoms, and Bullfrog's buoyant design makes you feel up to 90% lighter in the water, easing joint stress while building strength with 12 times the resistance of air. 3. Boost Your Immune System and Sleep Quality Who needs a stuffy gym when you can build resilience from the comfort of home? Regular hot tub soaks in fall and winter strengthen your immune response by improving lymphatic drainage and promoting detoxification through sweat. As temperatures drop and flu season ramps up around Platteville and Dubuque, staying ahead of sniffles means more time enjoying the holidays, not recovering from them. Bullfrog's Simplicity® Total Water Care System ensures crystal-clear water with up to 5-10 times fewer chemicals than traditional systems, minimizing exposure while keeping maintenance effortless—just what you need during busy winter months. And let's talk sleep—those long, dark nights beg for better rest. The buoyancy of hot tub water reduces gravity's pull on your body, easing pressure points and signaling your brain it's time to wind down. Research from the National Sleep Foundation indicates that a pre-bed soak can deepen REM cycles, helping you wake up refreshed for those early winter sunrises (or lack thereof). Owners rave about falling asleep faster and enjoying deeper slow-wave sleep after a Bullfrog session, thanks to the therapeutic warmth and optional chromatherapy lighting that sets a calming mood. 4. Create Magical Moments with Family and Friends Winter isolation? Not on our watch. A Bullfrog Hot Tub turns your backyard into a social hub, even when the snow flies. Host a fall foliage soak under string lights or a post-Thanksgiving bubble session with loved ones. The enclosed design keeps the warmth in, so you can chat, laugh, and connect without the bite of Iowa winds. With spacious, comfort-tested seating and premium headrests, everyone gets their perfect spot—whether it's a couple's retreat or a family gathering for up to seven. In communities like ours—where neighbors bond over bonfires and Packers games—a hot tub fosters those irreplaceable memories. It's family movie night elevated, date night redefined, or just a quiet soak with a good book and a mug of hot cocoa. Plus, the premium touch screen spa controls and optional app integration let you adjust settings from afar, so your gathering is always just right. 5. Enhance Circulation, Reduce Anxiety, and Support Overall Wellness Beyond the basics, Bullfrog Hot Tubs deliver advanced health perks tailored for winter's demands. The warm immersion lowers blood pressure by widening vessels and boosting kidney flow, while enhanced circulation supports brain health and cognitive function—ideal for shaking off seasonal blues. For those dealing with chronic pain or post-workout soreness from winter sports, the targeted jets suppress inflammation and speed cell recovery, as backed by studies on massage therapy. Anxiety melts away too—the simple act of soaking triggers full-body relaxation that combats mental stress, leaving you with a sense of well-being that carries through gray days. And for fitness enthusiasts, pre-soak warm-ups reduce injury risk, while post-use recovery cuts soreness, keeping you active when the cold might otherwise sideline you.
