The economic and ecological impact of invasive species in the Great Lakes has been dramatically underestimated, research suggests. In fact, according to researchers, a single non-native species in a single inland lake has racked up $80 million to $163 million in damage.
A new method to track how wetlands in Eastern Washington behave seasonally has been developed by scientists, which will also help monitor how they change as the climate warms.
Homes in rural and suburban areas often rely on private wells for the household water supply and on-lot septic systems for wastewater management. A homebuyer may not notice problems with these essential systems prior to purchase without proper inspections.
GroupGAP is a new food safety certification option that will increase opportunities for the entire industry to supply and buy GAP-certified produce. This robust certification process addresses certain challenges in complying with food safety audits, and meets the demands of the retail, food service, and institutional buying community. The GroupGAP Audit Program will begin April 4, 2016.
Strategic planting of trees on floodplains could reduce the height of flooding in towns downstream by up to 20 percent, according to a study by an international team of scientists.
The National Oceanic and Atmospheric Administration (NOAA) and the National Sea Grant College Program have awarded Sea Grant College status to Penn State based on the strength of Pennsylvania Sea Grant, a research and outreach program operated by Penn State Erie, The Behrend College. The designation reflects a sustained commitment to managing marine and coastal resources across the Commonwealth, including the Lake Erie, Delaware River and Susquehanna River watersheds.
Dangerous nitrate levels in drinking water could persist for decades, increasing the risk for blue baby syndrome and other serious health concerns, according to a new study.
Penn State Extension Water Resources Educator, Jim Clark, presented information on safe drinking water for private water supply owners at the Women in Agricultural Conference in Wellsboro, PA, in Tioga County, on March 23rd.
As Pennsylvania renews efforts to clean the state's waterways and the Chesapeake Bay, Penn State's College of Agricultural Sciences is helping to craft a strategy in which farmers spearhead clean-water initiatives.
Pennsylvania contains thousands of natural and man-made ponds and lakes but surveys by Penn State Extension have found that 77% of pond owners report problems with leaks, water quality, overabundant plant growth, fisheries management, or nuisance wildlife. More recently, algae blooms that release toxins harmful to animals and humans (called Harmful Algae Blooms or HAB’s) have become a common issue.
In 1993, the United Nations General Assembly designated March 22 as the first World Water Day. And with good reason – without water, we’d be nothing. Just dust. Water is one of the most common substances on earth, and one of the most vital; it’s a tremendously valuable resource, yet one we squander and pollute prodigiously.
New research shows that hormones found in birth control pills alter the genes in fish, which can cause changes in their behavior.
Until now, the link between rising water temperatures and higher mortality rates in aquatic animals was a bit of a chicken-and-egg situation. Are they dying because they're unable to absorb enough oxygen from the water? Or are they not absorbing enough oxygen because the warm water is killing them in a different way? A team of ecologists has answered this question in a new article: warm water speeds up the animals' metabolic need for oxygen to such an extent that it causes them to suffer from fatal respiratory distress.
Nature has its own economy, with trading as dynamic as that of any stock exchange. To cope with nutrient deficiencies in their respective habitats, certain plants, animals and fungi have evolved partnerships by which they can swap resources. In a new study, researchers analyze how nutrient pollution can negatively impact important ecological relationships.
Citing the tragedy unfolding in Flint, Michigan, Rep. Angel Cruz (D-Philadelphia) was joined by a bipartisan group of legislators Tuesday calling for support of a legislation package that aims to reduce the risk of lead poisoning in Pennsylvania.
Pennsylvania contains thousands of natural and man-made ponds and small lakes that are commonly used for irrigation, livestock or recreational purposes. Surveys of pond and lake owners by Penn State Extension have found that 52% complained of nuisance levels of aquatic plants or algae.
Overfishing reduces fish populations and promotes smaller sizes in fish. The fish also reach sexual maturity earlier than normal. However, the impact of overfishing is not restricted to fish: as the predators at the top of the food web dwindle, the stability of the entire aquatic ecosystem is at risk.
As fresh water resources become scarce, one option for water-conscious farmers is to water crops with treated wastewater. This effluent is becoming a more popular option for applications that don't require drinking-quality water. However, there are still questions about how the effluent interacts with and affects the rest of the ecosystem. Researchers set out to follow the environmental paths of four different compounds found in effluent when it is used to spray irrigate wheat crops.
Feasibility of rainwater recycling in four major US cities - Research by environmental engineers indicates that it rains enough in Philadelphia, New York, Seattle and Chicago that if homeowners had a way to collect and store the rain falling on their roofs, they could flush their toilets often without having to use a drop of municipal water.
From October 2011 through September 2015, NRCS helped Pennsylvania producers and landowners implement more than 95,000 conservation practices that will benefit future generations with healthy soils, clean water and air, conserved energy, an abundant water supply, and healthy plant and animal communities.
