    Is Fluoride Lowering Your IQ? I Read the Studies So You Don't Have To.

    Fluoride is under a federal microscope right now. RFK Jr. told the CDC to drop its fluoridation recommendation, Utah already banned it, and the EPA fast-tracked a new toxicity review. So, is your tap water lowering your IQ? I spent a while reading the actual primary sources both sides cite so you don't have to. Short version: the studies finding an IQ effect are real and well-designed. So are the studies finding none. They're mostly answering different questions. Dose and timing turn out to matter more than "fluoride: yes or no." I walk through where the evidence actually lines up, and where the genuine open question still is.// Full citations and in-text citations on Patreon: https://www.patreon.com/cw/TheAquaDiaryPodcastFree newsletter for updates and resources: substack.com/@aquadiarypodcastLearn more at aquadiary.org

    120 Homes, 40 Years, One Radioactive Story: Niagara County

    Radioactive material has been found in the yards of over 120 homes in the Town of Niagara, NY, and four families have been relocated. But is this just a soil problem, or could it reach the water too?In this episode, I break down what's actually been found, why officials reportedly knew about radioactive hotspots in this area for nearly 40 years, and what the peer-reviewed science says about whether thorium contamination can migrate into groundwater. Questions this episode answers: What is happening in Niagara County, NY right nowHow does soil radiation impact water supplies?What is "slag" and why is it radioactive?Is Niagara County linked to the Manhattan Project?Why did officials know about this for 40 years?What are agencies doing about Niagara County's radiation?

    PFAS, Algae, and Lake Foam: What Issues Are We Seeing in the Finger Lakes?

    There's a beach on one of the cleanest lakes in America with foam sitting on the shoreline, and it just tested over 70x higher for PFAS than the lake water two feet away. In this episode I sit down with Rick Smith of Global Aquatic Research to unpack what's actually happening across the Finger Lakes right now: the PFAS-in-foam research out of Canandaigua Lake and what it means as the project expands, why harmful algal blooms are starting earlier and lasting longer, and what we know about lake foam. This one got more unsettling than I expected, in the best way. 🔬 Guest: Rick Smith, Founder, Global Aquatic Research📍 Filmed in Auburn, NY - thank you to ARMA for the equipment and assistance. NOTE: This episode's interview segment was shot on a greenscreen. The background used behind Rick and me was purchased (and made custom) from an online marketplace and found to be AI-generated. I didn't know at the time of editing. I'll be vetting background sources more carefully going forward. All audio and footage of us is raw from the interview and unaltered.// Links: Follow Rick's Research: globalaquaticresearch.comGet Involved! - Introducing the Finger Lakes Foam Reporting Tool: https://www.globalaquaticresearch.com/finger-lakes.htmlNYSDEC HABs map & reporting: https://dec.ny.gov/environmental-protection/water/water-quality/harmful-algal-blooms/notificationsSupport the show on Patreon: https://www.patreon.com/c/TheAquaDiaryPodcastSubstack (free water quality guides): https://substack.com/@aquadiarypodcastInquiries: aquadiary.podcast@gmail.comwww.aquadiary.org

    Full Transparency: Water Treatment Tour in Rochester, NY

    Rochester, New York has been voted the best-tasting water in New York State twice. In this episode, I go inside the Hemlock Filtration Plant with the Rochester Water Bureau, for a complete walkthrough of how drinking water treatment actually works. This is the most in-depth water treatment plant tour I've filmed on this show. We walk through the entire process step by step, including pH Adjustment, coagulation, filtration, disinfection, corrosion control, and fluoridation. Beyond the treatment steps themselves, we see what it actually takes to run a plant like this day to day: how backwash filtering works to keep the filters clean and operating efficiently, how chemical storage and chemical feed systems are managed and maintained, and how the Water Bureau is approaching aging infrastructure, including an old tugboat generator still in use, for which replacement control parts can only be found on eBay. We also get into how tap water testing compares to bottled water regulation, and why your annual water quality report is one of the most underused resources for understanding what's actually in your water.

    Smoke on the Water: How Canada's Wildfires Change Lakes

    In 2023, Canada's wildfires turned the sky over New York the color of a traffic cone. In July 2026, it's happening again. Everyone covers the smoke in our lungs. Almost nobody covers what that same smoke does to our drinking water and lakes. This episode traces the whole chain: the light-blocking, algae-fertilizing double effect of ash on a lake surface, the "lake that turns to tea" carbon browning problem, the neurotoxin that works its way up the food chain into the fish on your plate, and what all of it means for the water coming out of your tap. I also talked to a silvicultural forester with the U.S. Forest Service (speaking personally, not for the agency) about the century of fire suppression policy sitting underneath all of this, and about a genuinely strange soil chemistry mechanism that turns a burned hillside into a mudslide waiting to happen. And yes, we go there on the oil and gas question: how much of this traces back to Alberta's oil sands, what the actual peer-reviewed attribution science says, and where that research runs out.If 2023 felt like a freak year, 2026 is making a strong case that this is just what North American summers look like now. For us, and for our lakes.// AquaDiary is an independent water science and investigative podcast that aims to teach people about water resources 🎙️ All sources cited on Patreon, full scripts for $3/mo - patreon.com/c/TheAquaDiaryPodcast📌 YOUTUBE MEMBERS — early access and monthly live Q&A🧪 NEWSLETTER – Free PDF on how to read your annual drinking water report [https://substack.com/@aquadiarypodcast]📩 SPEAKING + CONSULTING inquiries: aquadiary.podcast@gmail.com,New Website!

    Reflecting Pool Algae Pt. 2: A Silver Bullet Solution? Scientist Reviews Everything.

    Last week's reflecting pool video hit 400,000 views on YouTube. The most common question in the comments: is there actually a fix for algae? Copper sulfate. Silver. Hydrogen peroxide. Ultrasound. Aeration. I went through every tool, and gave you an honest verdict on each one.Is there a silver bullet for algae? What actually kills a harmful algal bloom? What are cyanobacteria toxins and how dangerous are they? How do you tell if a bloom is toxic just by looking at it? What do lake managers actually do differently? I'm Ally, an environmental scientist. I manage lakes and algae professionally, and I'm giving you the honest version of what works, what doesn't.

    $16 Million, Dead Ducks, and Algae: The Reflecting Pool Explained by a Scientist

    Why did the Reflecting Pool get an algae bloom? Why did thepaint peel off? Is the Reflecting Pool safe? What killed the ducks? Why did the $16 million renovation fail? I'm an environmental scientist and work professionally inlake and algae management, and this is my professional breakdown of what actually happened, why it was completely predictable, and what the science says about the decisions that were made, including the species identification thatmay have been inconclusive before workers poured chemicals into the water. The pool has had algae since 1922. This is not a newproblem. It is a physics and biology problem that no renovation has ever solved, and this episode explains why.
