Beneath the surface of rivers and streams, aquatic plants sway with the current, playing an unseen but vital role in the life of the waterway. Through a new series of experiments that model these underwater undulations, researchers have measured how the current bends simulated plants and the drag forces exerted on them. The analysis is important for better management and understanding of these aquatic systems, and potentially even for energy-harvesting devices.
Two Penn State researchers will play a key role in a multi-university study of the contribution that U.S. lakes make to global nutrient cycles, funded by a $4.2 million grant from the National Science Foundation.
Owners of private household water wells in areas threatened by flooding should address possible threats to their drinking water quality, according to Penn State and the National Ground Water Association.
More than 150 years after the first commercial oil well was drilled in Pennsylvania, decades of energy exploration have resulted in hundreds of thousands of abandoned, lost and forgotten oil and gas wells scattered across the state.
Penn State Extension Water Educator, Jim Clark, and Extension Water Specialist, Bryan Swistock, presented a workshop for Jefferson County Residents on Tuesday, September 27, 2016, Brookville, PA.
As global temperatures rise, how will lake ecosystems respond? As they warm, will lakes -- which make up only 3 percent of the landscape, but bury more carbon than the world's oceans combined -- release more of the greenhouse gases carbon dioxide and methane?
The Alliance for the Chesapeake Bay and the U.S. Forest Service presented the 2016 Chesapeake Forest Champions Awards at the 11th Annual Chesapeake Watershed Forum attended by over 420 people from various local organizations.
Keen gardeners stocking their domestic ponds with exotic or wild aquatic species could be inadvertently fueling the rapid spread of the lethally infectious frog disease ranavirus in England, according to new research.
Globally, approximately 2.2 billion people rely on groundwater for daily consumption. Approximately three million people in Pennsylvania rely on private wells.
In an effort to help protect stream health and aquatic life, the Pennsylvania Department of Environmental Protection (DEP) would like to remind private and public pool owners, as well as pool management companies, how to properly close their swimming pools for the season.
The PA Growing Greener Coalition Monday unveiled its blueprint for $315 million in new investments in a Growing Greener III Program to provide annual funding for clean water, parks and trails, green open spaces, and locally grown food.
The U.S. Environmental Protection Agency -- in conjunction with federal, state and local government and private sector partners -- is kicking off its fourth annual SepticSmart Week to encourage American homeowners and communities to properly maintain their septic systems.
About 25 percent of all housing units in Pennsylvania use on-lot septic systems for the treatment and disposal of household wastewater. Properly designed, installed and maintained on-lot septic systems provide adequate treatment and disposal of liquid household wastes.
Warming climate triggers changes in forests' impact on cleaner water. A warming climate is causing earlier springs and later autumns in eastern forests of the United States, lengthening the growing season for trees and potentially changing how forests function. Scientists have found that in years with early springs, trees use more nitrogen to grow than is naturally provided in soil, which could impact tree growth rates and the amount of carbon dioxide forests take out of the atmosphere.
All over the world, lakes, rivers, and coastal waters are threatened by high nutrient inputs. Nitrate or phosphates from waste-waters or fertilizers causes eutrophication. The consequence: Algae, in particular cyanobacteria (blue-green algae), grow uncontrollably and may release toxic substances. Hence, extensive water monitoring is indispensable for drinking water supply and water protection. Researchers have now develop a smart monitoring system, combining various technologies in a depth profile-measuring multi-sensor buoy for monitoring water bodies and in particular algae growth.
Department of Conservation and Natural Resources Secretary Cindy Adams Dunn Thursday announced the 2016 State Forest Resource Management Plan that will chart the course of Pennsylvania’s future state forests has been finalized and is now available.
While current efforts to curtail agricultural runoff will improve the health of Lake Erie, much more work will be needed to protect the streams that feed the lake, new research shows.
PPCPs are widely released into the world’s freshwaters and oceans, where they mix at low concentrations over long time periods and seep into diverse environmental pathways such as surface water, groundwater, drinking water or soil.
A new study contradicts the common assumption that down-the-drain disposal is an important source of pharmaceutical pollution in wastewater.
The decrease in fishery productivity in Lake Tanganyika since the 1950s is a consequence of global warming rather than just overfishing, according to a new report. The lake was becoming warmer at the same time in the 1800s that the abundance of fish began declining and the lake's algae started decreasing. Large-scale commercial fishing did not begin on Lake Tanganyika until the 1950s.
