Urban environments struggle with contaminated water running off, causing pollution and algal blooms. In response, cities often use natural landscapes of soil, grasses, and trees. These biofiltration systems capture and filter the runoff. Researchers measured how well tree species grew when watered with stormwater, and how well they took extra nutrients out of the stormwater.
Results of a 15-year study of factors affecting populations of Eastern brook trout with climate change show high summer air temperatures have a large influence, in particular on the smallest fry and eggs, which are most important to wild trout abundance in streams. Findings are expected to help nonprofit watershed conservation groups and state and federal wildlife managers identify, prioritize and protect habitat at sites most likely to have fish in the future.
Looking for a new way to engage community members in streamside restoration efforts? The Penn State Agriculture and Environment Center (AEC) and Penn State Extension have worked to develop a citizen science monitoring protocol that can easily and quickly show volunteers the good that comes from installing best management practices.
A new article has identified escape from aquaculture facilities, releases in the wild due to pet/aquarium trade and stocking activities as the main pathways of alien species introduction in European lakes and rivers. Germany, the UK and Italy are the main entry gateways. The authors recommend tightened controls, and improved prevention and management measures in order to halt the increasing trend of freshwater alien species introductions in Europe.
The Penn State Master Well Owner Network (MWON) recently added 17 new volunteers who completed the Fall 2015 online training courses. These volunteers join nearly 700 others who are dedicated to providing unbiased, research-based education on the proper management of private water wells, springs and cisterns.
The over-tapping of the High Plains Aquifer's groundwater beyond the aquifer's recharge rate peaked in 2006, new research shows. Its use is projected to decrease by roughly 50 percent in the next 100 years.
Do you teach about water? Could you teach about water? – Dive Deeper is the Summit for You!
Penn State Extension Educator, Jim Clark, received the 2015 Outreach and Education Award from the North American Lake Management Society (NALMS) Award Program Chair, Dick Osgood, at their annual conference in Saratoga Springs, NY, on Thursday, November 19.
The Penn State Extension Water Resources team recently reported their annual program impacts related to drinking water education.
The first data-driven estimate of the Earth's total supply of groundwater shows that less than six per cent of groundwater in the upper two kilometers of the Earth's landmass is renewable within a human lifetime.
An increasing amount of drugs taken by humans and animals make it into streams and waterways, and pharmaceutical pollution has had catastrophic ecosystem consequences despite low levels of concentration in the environment. The effect of pharmaceuticals and other contaminants of emerging concern on the environment has been the focus of recent research.
A growing number of farms and greenhouses in Pennsylvania rely on irrigation for crop production. Sources of irrigation water include wells, springs, streams, ponds, runoff and municipal water. Penn State surveys of irrigation water sources have found that the majority have water quality characteristics that may be problematic for crops or irrigation equipment, most commonly high pH, alkalinity and hardness.
The invasive northern snakehead fish found in the mid-Atlantic area is now cause for more concern, potentially bringing diseases into the region that may spread to native fish and wildlife, according to a team of U.S. Geological Survey scientists.
Most programs designed to promote soil health focus on encouraging farmers to adopt a prescribed set of practices, like cover cropping or nutrient management. Penn State Rural Sociology Doctoral Candidate Jennifer Hayden argues that a new approach is needed — one that instead works with farmers as they balance all the many influences particular to their own individual, unique farms. Hayden spent two years researching farms in the Chesapeake Bay watershed to understand agricultural soil health. Here, Hayden describes what she learned, and suggests a new model for helping farmers improve soil health.
Thanks to online availability, home gardeners can get their hands on practically any pesticide these days – including those intended for landscapers and farmers.
Penn State Extension Educator, Jim Clark, presented a Penn State Extension “Safe Drinking Water Display” at PA Representative Martin Causer’s Senior Expos in North Central Pennsylvania.
The one upshot to the appearance of an invasive species - that it might provide native predators with additional food - comes with some caveats, report scientists.
The ability to model subsurface movement of pollutants is a critical need within environmental sciences. On October 28, 2015, Dr. Li Li, an associate professor in Energy and Mineral Engineering at Penn State University, presented an online webinar on Predicting Flow, Transport, and Biogeochemical Reactions in Subsurface Environmental Systems Using Reactive Transport Models.
The Penn State On-line Pond Home Study Course is a 12-week class that covers six lessons, including getting to know your pond, pond maintenance, weed and algae control, fisheries management, ponds and wildlife, and pond case studies.
The numbers are in for the Lake Erie International Coastal Cleanup. Beginning on Saturday, September 19, and ending on October 2, volunteers picked up 6,853 pounds of trash along the 67.5 miles of Lake Erie shoreline and waterways within the County.
