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.
Penn State Extension assisted at the recent Pond and Lake Management Society (PALMS) Conference on February 24th and 25th, 2016, at the Ramada Inn in State College.
A new article warns of the dangers of increasing water salinity for human health and freshwater ecosystems (rivers, lakes, etc.) and the economic cost arising from a lack of public policies to tackle this problem.
The U.S. Environmental Protection Agency is now accepting applications for the Presidential Innovation Award for Environmental Educators. The deadline for nominations is May 16.
A team of scientists performed the first-ever experiment that manipulated seawater chemistry in a natural coral reef community in order to determine the effect that excess carbon dioxide released by human activity is having on coral reefs. Their results provide evidence that ocean acidification is already slowing coral reef growth.
Millions of tiny pieces of plastic are escaping wastewater treatment plant filters and winding up in rivers where they could potentially contaminate drinking water supplies and enter the food system, according to new research.
Does living near an oil or natural gas well affect the quality of your drinking water? 'The answer to that question is usually 'no,' but there are exceptions,' said an expert. He has found very high levels of natural gas in the tap water near active wells, and a surprising number of hydraulically fractured wells that penetrate shallow freshwater aquifers. 'In no other industry would you be allowed to inject chemicals into a source of drinking-quality water,' he said.
Inland freshwaters with a greater variety of fish species (biodiversity) have higher-yielding and less variable fisheries according to a new study. At least two billion people depend directly on inland freshwaters, such as lakes, rivers and wetlands, for the provision of food. However, despite thousands of freshwater species contributing to food security, the relationship between biodiversity and yield remains poorly understood.
An advanced system for treating manure on a commercial dairy farm did not remove estrogens and antibiotics. This new research underscores how far waste treatment systems have fallen behind the times, failing to remove chemicals used routinely in modern society.
Did you know that Invasive species are a billion dollar per year problem in the United States? Did you know that Invasive Species cause economic, ecological and human, animal or plant health harm?
USDA’s Natural Resources Conservation Service (NRCS) today announced that over $700,000 is available to help Pennsylvania agricultural producers improve water quality in selected high-priority watersheds through the National Water Quality Initiative (NWQI). Through NWQI, NRCS will help agricultural producers in three Pennsylvania priority watersheds in Bedford and Blair Counties apply conservation measures that contribute to cleaner water downstream, benefiting the Chesapeake Bay.
Each year, more than one trillion gallons of water are wasted by easy-to-fix household leaks, according to the U.S. Environmental Protection Agency’s (EPA’s) WaterSense program. That’s why EPA is encouraging consumers to “Be a Leak Detective” during WaterSense’s eighth annual Fix a Leak Week, March 14 through 20, 2016, by finding and fixing leaks around the home.
The "FreshWaterLIVE: A Distance Learning Adventure" brings the mysteries of freshwater to classrooms grades 4 to 8 through FREE webcasts, webinars, and online resources about the origins, travels, and perils of water from green forests and grasslands to household faucets.
If you utilize a private water well for your drinking water supply, chances are you realize the importance of groundwater. Not only is groundwater supplying your well with water that you are able to use in your home, but it also plays a role in recharging surface water sources – lakes and rivers – from the ground up.
Researchers at Penn State University have created a factsheet to help growers decipher what the data on their water tests mean. Included are practical definitions of each component in a reading, which measurements should lead to concern, and how the components can be stabilized and/or removed. Bryan Swistock, Penn State Extension’s senior associate & water resources coordinator, explains the reasoning behind the factsheet and shares the biggest irrigation issues growers face.
Scientists have adapted traditional asset valuation approaches to measure the value of such natural capital assets, linking economic measurements of ecosystem services with models of natural dynamics and human behavior.
