Stormwater Risers
11/02/26
“How can we connect catch basins to sewer systems using a vertical pipe?”
Catch basins hold rainwater, and sewer systems carry water away. These can connect to vertical pipes called Stormwater Risers. Stormwater risers safely separate detention systems from sewer systems while giving maintenance professionals access to visually inspect sewer pipes from above.
Why Philadelphia May Need to Install Desalination Units in Its Water Supply
11/01/26
“Why may Philadelphia need to install desalination units in its water supply?”
The Delaware River is suffering from major saltwater intrusion from sea-level rise and over-extraction. Philadelphia relies on the Delaware River for most of its drinking water. The freshwater-saltwater interface may soon reach Philadelphia’s drinking water supply. Installing desalination units is one adaptation strategy. This is Why Philadelphia May Need to Install Desalination Units in Its Water Supply.
Blackwater Rivers
10/31/26
“Why are some rivers darker and slow-moving?”
Warm, damp forests have lots of vegetation. This vegetation can fall into rivers, clogging the waters with decaying organic matter. The dissolved compounds turn the river dark and acidic, and the inertia from the dead weight slows the water down. These Blackwater Rivers are largely nutrient-poor due to their acidic waters.
Mires
10/30/26
“How do we classify peatlands that still produce peat?”
Peatlands may no longer produce peat if they are burned or drained. Peatlands that are still waterlogged and produce peat are called Mires.
When Do Peatlands Stop Producing Peat
10/29/26
“What causes peatlands to stop producing peat?”
Peatlands produce peat from their water-saturated conditions. If a peatland is drained or burned, these conditions can fall away. This is When Peatlands Stop Producing Peat.
Peatlands

“How do we classify wetlands that produce peat?”
Peat is a buildup of dead leaves in high-moisture, low-oxygen conditions. Peatlands are wetlands that produce peat. Peatlands are the highest land-based carbon storage source on Earth.
Fens
10/27/26
“What types of groundwater-dependent wetlands accumulate peat?”
Swamps come in all different types. Some wetlands are dependent on high groundwater tables that accumulate peat. These so-called Fens typically have mineral-rich conditions that support large plant life. Fens typically have higher ph level than bogs.
Bogs
10/26/26
“What types of rain-dependent wetlands accumulate peat?”
There are a myriad of different types of wetlands. Wetlands that rely on precipitation and accumulate peat are called Bogs. Bogs have low oxygen and high acidity levels. Because bogs are typically fed by precipitation instead of nutrient-laden groundwater, plants in bogs may have adaptations to survive in these harsh conditions, such as carnivory.

Peat
10/25/26
“What happens when large layers of dead vegetation pile up in a wetland?”
Vegetation grows and dies. Dead plant material in a waterlogged environment may decay slowly due to a lack of available oxygen. More dead material will pile up over time, leading to the creation of Peat. Peat is an organic material that stores carbon from the original plant material, retains and filters water, and supports ecosystems.
