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.
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.
If you are a pond owner, early spring is a good time to take a walk around your pond and check to see if any maintenance is needed.
Every system in your house needs monitoring and maintenance. Just as you check your furnace or smoke detector batteries seasonally, spring is a good time to perform a water well checkup.
Greenhouse and crop producers across Pennsylvania use, on average, over 27 million gallons per day for irrigation. Over 15,000 acres of irrigation occurs in micro-irrigation systems commonly found in greenhouses. Unfortunately, the quality of these water supplies is often overlooked as a potential source of plant growth issues.
A professor has shown that improving wastewater treatment and saving energy are not only essential, but they’re also compatible.
Simply removing cattle may be all that is required to restore many degraded riverside areas in the American West, although this can vary and is dependent on local conditions, researchers have found after comparing repeat photographs to assess rehabilitation of Oregon wildlife refuge. The team analyzed photographs to gauge how the removal of grazing cattle more than two decades ago from Hart Mountain National Antelope Refuge in eastern Oregon has helped to rehabilitate the natural environment.
Rivers and streams could be a major source of antibiotic resistance in the environment. A new study found that greater numbers of resistant bacteria exist close to some waste water treatment works, and that these plants are likely to be responsible for at least half of the increase observed.
Penn State Extension Water Resources Educator, Jim Clark, based in McKean County, PA, assisted farmers and other pesticide applicators protect the groundwater that flows beneath their feet by offering an extension program about groundwater.
Arsenic is the biggest public-health problem for water in the United States -- yet we pay far less attention to it than we do to lesser problems. Private wells present continuing risks. Even low doses of arsenic may reduce intelligence in children. There are also well-documented risks of cancer, heart disease, and reduced lung function.
Pennsylvania has over three million rural residents who use a private water supply (well, spring or cistern) yet it is one of only two states that do not provide statewide standards for the construction, location or maintenance of these water supplies. As a result, each private water supply owner in Pennsylvania must become educated on best management practices for their water supply.
The Delaware River watershed is one of our nation’s most treasured resources. It is home to more than 7 million people and the water supply for more than 15 million in New York, Pennsylvania, New Jersey and Delaware. An historic new Farm Bill program at USDA’s Natural Resources Conservation Service (NRCS) will help farmers and local leaders make investments to keep the watershed healthy and vibrant for years to come.
