Insight into how large-scale deforestation could impact global food production by triggering changes in local climate has been gained by new research. In the study, researchers from the United States and China zero in on albedo (the amount of the sun's radiation reflected from Earth's surface) and evapotranspiration (the transport of water into the atmosphere from soil, vegetation, and other surfaces) as the primary drivers of changes in local temperature.
A recent webinar sponsored by the Penn State Extension Water Resources team highlighted the ongoing work to develop the new Master Watershed Steward program in the state.
Consumers whose drinking water can be contaminated by the release of untreated wastewater after heavy rains face increased risk for gastrointestinal illness, according to a report. Many older cities such as Chicago have combined sewer systems -- along with 772 other communities, primarily in the Northeast, Great Lakes and Pacific Northwest, serving a total of 40 million people. While some cities are building infrastructure to handle sewage and runoff separately, other regions with combined systems depend on reservoirs to provide extra capacity during extreme rainfalls.
A new online, interactive tool for estimating atrazine concentrations in streams and rivers is now available.
Poop could be a goldmine -- literally. Surprisingly, treated solid waste contains gold, silver and other metals, as well as rare elements such as palladium and vanadium that are used in electronics and alloys.
A New Democratic Party Member of Parliament is calling on the Canadian government to list microbeads, tiny plastic flakes used in cosmetics, as a potential toxic substance. Health Canada claims the beads are safe for use as an additive, but this MP says they pose a danger to the aquatic environment. Researchers are warning that microbeads and plastic debris of all sizes could be a bigger environmental problem for the Great Lakes than previously thought.
The Senate and House Appropriations Committee hearings on Gov. Wolf’s proposed budget for the Department of Environmental Protection are now complete. Here are five things we learned as a result of those hearings--
The Penn State Extension Water Resources Team was present at the Pennsylvania Lake Management Society Annual Conference at the Ramada Inn in State College, Pa, on March 18 and 19, 2015. Extension Water Educators helped out by moderating and teaching educational sessions and presenting an educational poster for conference participants.
Most models predict that rivers only transport sediment during conditions of high flow and, moreover, that only particles on the surface of the river bed move due to the force of the flowing water above. But using a custom laboratory apparatus, a new study shows that, even when a river is calm, sediment on and beneath the river bed slowly creeps forward.
Karst geology can be found in areas of Pennsylvania where it can lead to sink holes and water quality problems. This video explains the geology of karst formations and how they affect water movement.
An atomically thin membrane with microscopically small holes may prove to be the basis for future hydrogen fuel cells, water filtering and desalination membranes, according to a group of 15 theorists and experimentalists, including three theoretical researchers from Penn State.
Residence time of leaves and twigs, important to stream-dwelling species, can be halved.
On Saturday, April 11 2015 from 9am to 12pm the Penn State Agricultural and Environment Center will host a FREE community workshop on The Homeowner’s Guide to Stormwater. This Guide will help you create your own stormwater management plan and select simple stormwater solutions to be implemented on your property.
Despite the recent surge of surface water caused by snow melt, parts of the state have below-average groundwater levels. The lack of groundwater recharge has caused the Department of Environmental Protection (DEP) to issue a drought watch for 27 counties across Pennsylvania. Low groundwater levels can cause well-fed water supplies, both private and public, to go dry.
Use of rainwater cisterns is nothing new. They were used by both Greek and Roman civilizations and the same basic principles are used in modern-day systems.
You turn the faucet on and there's water; but where does it really come from? Pennsylvania has over a million water wells, which need to be drilled right and kept clean. Join the Pa. Geologic Survey's Gary Fleeger as he steps us through how a well is drilled and what to look for to keep your water source in good shape.
The Department of Environmental Protection Thursday encouraged all Pennsylvanians to protect public health and the environment by honoring National Groundwater Awareness Week March 8 to 14.
Pennsylvania farmers can use PAOneStop to map fields and reduce soil erosion.
Streams within approximately 40 percent of the global land surface are at risk from the application of insecticides. These were the results from the first global map to be modeled on insecticide runoff to surface waters. Streams, especially those in the Mediterranean, the United States, Central America and Southeast Asia are at risk.
Many of the communities we live in strive to provide a clean environment to their citizens including clean water, green recreation areas and parks, agricultural fields and tree-lined commercial areas. Green infrastructure – a natural approach to managing rainfall with trees, rain gardens, wetlands and other natural areas can protect our water quality while also providing green space which attracts residents, visitors and commercial businesses.
