Across Maryland’s Eastern Shore, more than 550 concentrated animal feeding operations produce over 300 million chickens each year—and with them, massive waste streams. According to modeling, these facilities emit 30 to 40 million pounds of ammonia annually, much of it vented into the air, where it later settles into rivers…
Across the Chesapeake Bay watershed, agriculture plays a critical role in both food production and water quality. When manure and fertilizer are carefully managed, they support healthy soils and crops. But when they’re oversupplied—or when permits and oversight fall short—excess nutrients can move off fields and into nearby streams, making…
The warning signs didn’t come from inside the plant—they came from the water itself. Routine monitoring by Blue Water Baltimore detected high bacteria levels outside the Patapsco Wastewater Treatment Plant, signaling that something was going wrong deep inside the system, says Alice Volpitta, Baltimore Harbor Waterkeeper. It turns out there…
Beneath city streets and behind concrete walls, some of the Chesapeake Bay’s most important environmental work happens every day. Wastewater treatment plants across the region discharge into rivers that flow to the Bay—carrying nitrogen and phosphorus that, if not properly treated, can quickly undo decades of restoration progress. The good…
Muddy runoff construction from a single subdivision smothered one of the Chesapeake Bay’s vital nurseries—turning crystal-clear waters into a hazy graveyard for underwater grasses that shelter crabs and fish. Over the past four years, more than 200 failed state inspections at Ridgely’s Reserve have allowed relentless sediment to cloud the…
Rain doesn’t always look like pollution—but with every storm comes a hidden threat. As forests and fields are replaced by roads, rooftops, and parking lots, rainwater that once soaked into the ground now rushes across hard surfaces, carrying dirt, oil, nutrients, and other contaminants straight into local streams and rivers…
What happens when laws designed to protect water fail — and what legal action does it take to set things right? For decades, the health of the Chesapeake Bay has struggled because of three major pollution sources: stormwater, wastewater, and agriculture. These pressures send nitrogen, phosphorus, and sediment into streams…
When pollution controls fall short, rivers pay the price. Across the Chesapeake Bay watershed, stormwater runoff, deteriorating wastewater infrastructure, and industrial agriculture continue to send nitrogen, phosphorus, and sediment into local waterways—despite years of restoration progress. Riverkeepers across Maryland explain how these failures show up: sediment smothering habitat in the…
What happens when laws designed to protect water fail — and what legal action does it take to set things right? For decades, the health of the Chesapeake Bay has struggled because of three major pollution sources: stormwater, wastewater, and agriculture. These pressures send nitrogen, phosphorus, and sediment into streams…
Green infrastructure has undergone a dramatic evolution in just two decades, shifting from sprawling retention ponds and grassy swales to compact, high-performance systems that fit seamlessly into dense urban sites. Christian Hennessy of Oldcastle Infrastructure highlights how precast manufacturing has driven this modernization, delivering simple, structurally sound solutions with smaller…
Rigorous field testing is unlocking the true power of green infrastructure, delivering hard data on how effectively systems clean real-world stormwater. Christian Hennessy of Oldcastle Infrastructure explains that by capturing grab samples of influent and effluent, these tests precisely measure removal of total suspended solids, phosphorus, nitrogen, and metals—providing the…
What if the real game-changer in green infrastructure isn't adding more plants, but engineering the soil itself to become a pollutant-trapping powerhouse? Christian Hennessy of Oldcastle Infrastructure says the science of media development—fine-tuning soil matrices, depths, and materials—has been key to evolving from basic solutions to modern systems that deliver…
As new contaminants like PFAS demand complex treatment, many utilities face a hard reality: innovative solutions often stall at the regulatory desk. That bottleneck — not a lack of technology — is what Anthony DeRosa is working to fix. As Executive Director of the Association of State Drinking Water Administrators,…
Green infrastructure is reshaping how communities manage stormwater by blending natural processes with modern engineering to improve water quality, reduce flooding, and fit into increasingly dense urban spaces. In this episode, Christian Hennessy of Oldcastle Infrastructure breaks down what makes a system truly “green,” from mimicking pre-development hydrology to using…
The water sector can’t fully serve communities if it doesn’t reflect them — and for too long, people of color have been underrepresented across the industry. That lack of representation creates trust gaps, reinforces barriers, and signals to many young professionals that they don’t belong. That’s the challenge Patricia Lindsay-Harvey,…
Clean water in national parks isn’t protected by accident — it’s defended by policy and by confronting the pressures outside park boundaries. Ed Stierli of the National Parks Conservation Association says that safeguarding these waters means not only upholding strong laws like the Clean Water Act, but also tackling the…
America’s national parks don’t just protect landscapes — they safeguard some of the most important waters in the country, from the Great Lakes and the Chesapeake Bay to the Colorado River, the Everglades, and even 10% of the nation’s coastline. These places give millions of people a chance to fish,…
Protecting America’s national parks has never been a passive job — and for more than a century, citizens themselves have stepped up to defend the waters, wildlife, and landscapes that define these iconic places. The National Parks Conservation Association was created in 1919 to be that independent voice, and today…
What if you could spot a failing motor or gearbox long before it breaks? Utilities are making that a reality by turning to smart sensor technology that tracks vibration, temperature, and performance around the clock. The power isn’t just in real-time warnings — it’s in long-term trending data that reveals…
Water is at the heart of America’s national parks, yet many of these rivers, lakes, coasts, and wetlands are under growing stress from pollution, climate impacts, and decisions made outside park boundaries. In this episode from the Reservoir Center in Washington, D.C., Ed Stierli of the National Parks Conservation Association…
Cleaning water depends on nonstop power behind the scenes — and every pump, motor, and ditch in a wastewater plant has to run 24/7 to keep communities safe. The real challenge? Managing massive, constant energy demand while still delivering reliable treatment. Dave Zimmerman of Dodge Industrial explains how smarter mechanical…
Along California’s coast, protecting groundwater from seawater means knowing exactly what’s happening beneath the surface. Denver Grant of the Soquel Creek Water District explains how the team uses 84 coastal monitoring wells to track groundwater quality and watch for signs of seawater intrusion. By sampling for chlorides, total dissolved solids,…
Along California’s coast, saltwater intrusion can permanently contaminate groundwater—creeping inland as basins are pumped faster than they recharge. Melanie Mow Schumacher of Soquel Creek Water District explains how the community built a solution: sending treated wastewater four miles to an advanced purification facility, then another four miles to seawater-intrusion prevention…
Wastewater treatment plants rely on nonstop mechanical power to keep water moving, oxygen flowing, and critical equipment turning—and the systems behind that power are the focus of this episode. Dave Zimmerman of Dodge Industrial breaks down how gearboxes, bearings, motors, and couplings form the “powertrain” that drives nearly every major…
