Many Pennsylvania farmers in the Chesapeake Bay watershed have voluntarily implemented, at their own expense, practices aimed at improving water quality, according to newly released survey research conducted by Penn State's College of Agricultural Sciences.
The National Lakes Assessment (NLA) is a statistical survey of the condition of our nation's lakes, ponds, and reservoirs. It is designed to provide information on the extent of lakes that support healthy biological condition and recreation, estimate how widespread major stressors are that impact lake quality, and provide insight into whether lakes nationwide are getting cleaner.
The Pennsylvania Department of Environmental Protection (DEP) has placed four more counties on drought warning status following a meeting today of the Commonwealth Drought Task Force. While recent precipitation over the past few weeks has helped dry conditions in the eastern part of Pennsylvania, the central part of the state still has persistent 90-day precipitation deficits of up to 4 inches from normal as well as low groundwater and stream levels.
A new online interactive mapping tool provides summaries of decadal-scale changes in groundwater chemistry across the Nation.
Over half of Pennsylvania residents rely on groundwater for at least part of their drinking water. Groundwater is also the predominant source of water used for agriculture, commercial and mining activities in the state. While Pennsylvania has abundant groundwater resources, it is critical that they be properly protected from pollution associated with land use activities. Use of pesticides represents one such groundwater threat.
The Penn State Extension Master Watershed Steward Program was established to help address non-point source pollution, which remains one of the biggest challenges facing surface water quality in Pennsylvania.
Chesapeake Bay Program partners are welcoming the review of new high-resolution land use data for all 206 counties in the Chesapeake Bay watershed. The data will inform the partnership’s next generation of models used to estimate nutrient and sediment loads and to credit efforts to reduce those pollutants from draining into the nation’s largest estuary.
Study finds life under the ice is vibrant, complex and surprisingly active - As long as ecologists have studied temperate lakes, the winter has been their off-season. It's difficult, even dangerous, to look under the ice, and they figured plants, animals and algae weren't doing much in the dark and cold anyway. But an international team of 62 scientists looking at more than 100 lakes has concluded that life under the ice is vibrant, complex and surprisingly active. Their findings stand to complicate the understanding of freshwater systems just as climate change is warming lakes around the planet.
Agricultural businesses and pesticide applicators in 15 counties can dispose of unwanted pesticides safely and easily in 2017 through the Pennsylvania Department of Agriculture’s CHEMSWEEP program. The program is offered in different counties each year. In 2017, it will be available in Bedford, Berks, Bradford, Butler, Columbia, Cumberland, Fulton, Lawrence, McKean, Montour, Northumberland, Schuylkill, Sullivan, Warren and York counties.
Penn State’s Greening the Lower Susquehanna volunteer corps had a successful 2016 filled with tree plantings, litter pickups, maintenance days, and other exciting volunteer events.
Short-term laboratory exposure of adult fathead minnows to the human contraceptive progestin, gestodene (GES), at environmentally relevant concentrations induced rapid and negative effects on reproductive health and suggests that wild fish may be similarly affected.
Changes in the regulation and use of some organic chemicals have caused environmental concentrations to stabilize or decline during the past 35 years coincident with a rebound in the osprey (Pandion haliaetus) population of the Chesapeake Bay.
A U.S. Geological Survey study published today combines climate change and invasive species research by examining how native Brook Trout interact with non-native Brown Trout under rising stream temperatures.
Future climate change scenarios predict warmer and wetter conditions across Pennsylvania which raises concerns for increased occurrence of flooding. Pennsylvania Sea Grant and a host of partners have been helping coastal communities along the Delaware River to prepare for the flooding and extreme heat expected with future climate change.
Following a meeting Wednesday of the Commonwealth Drought Task Force, the Pennsylvania Department of Environmental Protection (DEP) announced no changes in county drought declarations, despite recent precipitation. Conditions will continue to be monitored, with drought declarations reassessed when the task force meets again in two weeks
A new, web-based interactive tool has been developed to increase access to the Department of Interior (DOI) Natural Resource Damage Assessment and Restoration (NRDAR) Program information.
Water and atmospheric processes are inseparable. Now, there is a supercomputer model that couples climate and hydrodynamic factors for the Great Lakes region. The new model will be useful for climate predictions, habitat modeling for invasive species, oil spill mitigation and other environmental research.
The Penn State Extension Water Resources Team has released a new “LearnNow” video on Protecting Your Water Well. LearnNow videos are short, narrated PowerPoint presentations that are new learning tool being utilized by Penn State Extension.
Naturally occurring chemicals found in road salts commonly used to de-ice paved surfaces can alter the sex ratios in nearby frog populations, a phenomenon that could reduce the size and viability of species populations, according to a new study.
For years, public health experts have warned against eating certain kinds of fish, including tuna, that tend to accumulate mercury. Still, tuna consumption provides more mercury to U.S. consumers than any other source. But recently, as industry cuts down on its mercury emissions, research has found mercury concentrations in some fish are dropping. The latest study, published in Environmental Science & Technology, reports that this is the case for prized Atlantic bluefin tuna.
