AquaDiary: Water Mysteries, Science & News

Rochester, NY has thousands of lead water service lines and a plan to replace all of them by 2030, years ahead of the federal deadline, at virtually cost to residents. How did they do it? And is the water in Rochester, NY safe to drink? In this episode, I go inside the Rochester Water Bureau's in-house lab to see exactly how lead testing works, down to the part-per-billion level. Then I sit do...

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 da...

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 decision...

Microplastics have been found in 83% of tap water samples tested worldwide, and yes, that includes yours. But here's what almost no one covering this topic will actually say: as of 2026, peer-reviewed science does not yet have a definitive answer on what that means for your health. I'm an environmental scientist, and this episode gives you the honest version; the research, the real gaps, a...

Micron Technology is building the largest semiconductor fabrication complex in U.S. history in Clay, New York, and its wastewater will carry ( mostly unregulated) PFAS, the "forever chemicals," into a river system that connects to drinking water for half a million people. I'm an environmental scientist, and today we're doing the math the press releases aren't doing: what a $100 billion megafab and...

In 2014, a man in a small New York town did something almost no one does: he tested his own tap water. What he found, PFOA, a “forever chemical,” at hundreds of times the level regulators consider safe, would expose a national scandal and take roughly 18 months to be officially acknowledged. This is the story of Hoosick Falls, the frying-pan chemistry that poisoned a town’s drinking water, and why...

A few weeks ago I was at a conference when someone from the City of Rochester's water bureau found me in person to ask for a follow-up deep dive into their water supply. On the drive home, I stopped in Saratoga Springs, and tried the water. I later learned that peer-reviewed science has found it contains radium isotopes and radon gas. The state tests the popular one. Not all of them. I want to sol...

The scientists who worked on this cleanup all signed NDAs and wouldn't speak with me. And mercury is still being found. In April 2026, routine marina renovations at Onondaga Lake uncovered mercury in sediment nobody had ever tested, in a lake declared cleaned up. The DEC says the origin is "unknown." The Onondaga Nation says they've been ignored for twenty years. And the experts...

21,800 tons of toxic chemical waste buried under a neighborhood and a school. Hundreds of families in Love Canal had no idea. This is the story of America's most infamous environmental disaster, and the woman whose anger created federal law. Lois Gibbs was a 27-year-old housewife when she discovered her children were being poisoned by groundwater contamination seeping up through the soil benea...

Rochester was voted the best-tasting municipal water in New York State. Then they found a body in the reservoir. In March 2024, a maintenance worker discovered a man's body in Rochester's Highland Park Reservoir. It had been there for 24 days while water continued flowing to tens of thousands of taps. The water tested safe, but the story of how this was possible opens up something much lar...

Bottled water is less regulated, less safe, and less transparent than your tap — and the industry spent billions making sure you never found out. In this episode of AquaDiary, environmental scientist Ally breaks down the science, the scandals, and the corporate playbook behind the bottled water industry. From FDA loopholes and hidden contamination to Nestlé pumping 130 million gallons for $200 a y...

Lead pipes and lead poisonings aren't problems we've solved. They're under streets across the country right now, and new evidence suggests the problem is significantly larger than official data ever indicated. In this episode, environmental scientist Ally breaks down the full story of lead in American drinking water: the aging infrastructure nobody wants to pay to fix, the chemistry th...

Syracuse, New York gets its drinking water directly from Skaneateles Lake. No filtration plant, no treatment beyond chlorination... and it has worked perfectly for 130 years. Then in 2024, the lake recorded 145 confirmed harmful algal blooms. The year before: 19. This episode is about what changed, what the science actually shows, and what 165,000 people probably don't know about the water com...

On the night of August 21, 1986, the residents of Cameroon's Nyos valley went to sleep and never woke up. Nearly 1,700 people and thousands of livestock were found dead by morning. No signs of struggle, no visible cause. Just silence and 4 very confused survivors. The lake was the murderer. In this episode, we cover the full story of Lake Nyos: the night of the disaster, the survivors who desc...

The water in your glass right now has existed for over four billion years. It has been part of oceans, glaciers, clouds, rivers, and yes — other living things. It is the same water, cycling endlessly. In Episode 1 of AquaDiary, environmental scientist and host, Ally breaks down the water cycle - not the oversimplified version you learned in school, but the full picture. How water moves through eva...

Beach closures after rain aren't random. They're the result of a stormwater and sewer system that was never designed to handle what we're asking it to do — and in hundreds of American cities, including many in New York State, that system is sending raw sewage and dozens of chemicals directly into lakes and rivers when it downpours. In this episode, environmental scientist Ally breaks down how stor...

In 2014, a harmful algae bloom shut off drinking water for nearly half a million people in Toledo, Ohio. The city spent 65 million dollars responding. They've invested half a billion dollars in upgrades since. And every summer, the blooms come back. Harmful algal blooms are getting worse. And the reason why is more complicated than most people realize, and more alarming than most officials or lake...

What are toxic algae, and how dangerous are they really? In this episode of AquaDiary, Ally breaks down the health risks of harmful algal blooms (HABs), including cyanotoxins like microcystin, how exposure can affect people and pets, why dogs can die within hours, what the health advisory limits are federally and by state, what toxic blooms mean for lakes and drinking water systems, how to find ou...

Owasco Lake supplies drinking water to 45,000 people in central New York. In 2016, it made history, for the wrong reason. Cyanobacterial toxins were detected in the finished drinking water of a New York State public water system for the first time ever. Since then, the blooms have gotten worse, the lawsuits have piled up, and a number that gets cited constantly in the press may not be telling the...
