If they successfully invade Lake Erie, Asian carp could eventually account for about a third of the total weight of fish in the lake and could cause declines in most fish species -- including prized sport and commercial fish such as walleye, according to a new computer modeling study.
Taking on the rising problem of stormwater runoff.
Recent stories from Flint, Michigan have highlighted the important issue of lead in drinking water. High concentrations of lead have been linked with many serious health effects, especially in young children. While state and federal regulations exist to monitor and prevent lead contamination of municipal water supplies, homeowners using private water wells, springs or cisterns need to be more vigilant.
One of the most useful - and often missing – records a private well owner can have is the well completion report. This is the report that documents the construction of the well and the geology that will determine so much of the water quality.
Four Federal agencies, including the U.S. Geological Survey (USGS), are collaborating to transform satellite data into information managers can use to protect ecological and human health from freshwater contaminated by harmful algal blooms.
Each year, pesticide products are cancelled by the manufacturer or phased out by operations, leaving farmers and professional applicators with quantities of unwanted and/or unusable pesticides. Due to the nature of these materials, there are often limited options available for responsible management. The high cost of disposal prohibits many users from hiring waste disposal contractors to collect and dispose of these materials. The waste pesticides may then become a safety hazard or environmental liability through long-term storage in barns and other areas in and around the farm or business.
A modified or "rapid" version of an existing wetland assessment tool can accurately assess the quality of wetlands, according to Penn State researchers. Using the rapid version of the tool, known as the Floristic Quality Assessment Index (FQI), can save time and improve upon wetland monitoring strategies.
After 30 years of work that has prevented millions of pounds of pollutants from reaching Pennsylvania’s waterways and the Chesapeake Bay, the commonwealth continues to face immense pressure from the federal Environmental Protection Agency (EPA) to improve water quality. In order to meet those obligations, Pennsylvania today unveiled a comprehensive strategy to “reboot” the state’s efforts to improve water quality in the commonwealth and the bay.
On Tuesday, December 15 Matt Royer, director of Penn State’s Agriculture and Environment Center, kicked off a new collaborative project entitled “Chiques Creek Reinvisioned”. Penn State was recently awarded a Chesapeake Bay Stewardship Fund grant from the National Fish and Wildlife Foundation to facilitate a watershed partnership in the Chiques Creek watershed.
If you enjoy wildlife, fishing, nature walks, paddle sports and other streamside activities, Penn State's College of Agricultural Sciences now is giving you a chance to parlay those interests into becoming a citizen-scientist by observing and recording environmental and ecosystem changes. The only tool needed is a pencil or smartphone.
A recent U.S. Geological Survey (USGS) study provides a rare glimpse into how nitrate levels in 22 large rivers across the Nation have changed during the past 65 years. Despite the stabilization of nitrogen inputs in recent decades, there is no evidence of widespread decrease in nitrate levels in rivers.
One of the biggest challenges in preventing arsenic exposure from drinking water may be public perception, according to a recent special section of Science of the Total Environment. In this special section of 13 papers report on new understanding of arsenic hydrogeochemistry, performance of household well water treatment systems, and testing and treatment behaviors of well users in several states of the northeastern region of the United States and Nova Scotia, Canada.
Conference organizers are now accepting proposals for Presenters and Exhibitors at the 2016 Dive Deeper III Summit. Dive Deeper is the biennial youth water educators summit hosted by Penn State Extension. The Dive Deeper III Summit will be held on Thursday, September 22, 2016 in Harrisburg, PA.
If you're a farm operator in the Chesapeake Bay watershed, you soon will have a chance to highlight what steps you and your fellow farmers have taken to protect and enhance water quality in the region.
A new U.S. Geological Survey (USGS) study determined that the microbiology and organic chemistry of produced waters varied widely among hydraulically fractured shale gas wells in north-central Pennsylvania.
Manure spills may be an underappreciated pathway for livestock-derived contaminants to enter streams. Scientists from the U.S. Geological Survey (USGS) and Johns Hopkins Bloomberg School of Public Health studied an Iowa stream after the release of a large volume of swine manure (a manure spill). The scientists observed an increase in viruses and bacteria, which have the potential to cause human or swine disease, in the stream water and bed sediment. This study applied molecular techniques to identify microbial contaminants that were transported as far as 4 kilometers from the spill origin. The microbial contaminants persisted for several weeks in stream water and sediments after the spill. This study documented that stream sediment was a persistent reservoir of contamination following this manure spill.
The Penn State Extension Water Resources Team recently released a new “LearnNow” video on Roadside Springs. LearnNow videos are short, narrated PowerPoint presentations that are new learning tool being utilized by Penn State Extension.
The answer is … for each … one can earn the title of “Master”. While Hollywood dreamed up the idea of a Jedi Master, the Pennsylvania State Extension has devised programs in which one can earn the title of Master Gardener as well as the title of Master Well Owner.
The Department of Environmental Protection (DEP) today urged all Pennsylvanians to test their homes for radon, a deadly radioactive gas that’s the leading cause of lung cancer in non-smokers in the United States. DEP also urged residents to take action to reduce radon levels in their homes if they are high.
A new online graphical data tool that provides annual summaries of nutrient and sediment concentrations and loads and streamflow information is now available from the U.S. Geological Survey (USGS).
