PPCPs are widely released into the world’s freshwaters and oceans, where they mix at low concentrations over long time periods and seep into diverse environmental pathways such as surface water, groundwater, drinking water or soil.
A new study contradicts the common assumption that down-the-drain disposal is an important source of pharmaceutical pollution in wastewater.
The decrease in fishery productivity in Lake Tanganyika since the 1950s is a consequence of global warming rather than just overfishing, according to a new report. The lake was becoming warmer at the same time in the 1800s that the abundance of fish began declining and the lake's algae started decreasing. Large-scale commercial fishing did not begin on Lake Tanganyika until the 1950s.
Kansans who own water wells show more awareness of state water policy issues than those who rely on municipal water supplies, according to a study that could have implications for groundwater management and environmental policies.
Norristown, PA – The Pennsylvania Department of Environmental Protection has released results of surveillance for Aedes mosquitoes, which have been found to be vectors of the Zika virus. At this time, there have not been any cases of Zika transmitted locally in Pennsylvania, nor have mosquitoes tested positive for the virus.
Hundreds of homeowners with private water wells, springs, cisterns, ponds or lakes received educational assistance at two exhibits during Ag Progress Days on August 16-18, 2016.
A recent study out of the University of Colorado indicates since introduction of horizontal drilling combined with high-volume hydraulic fracturing, the rate of groundwater contamination remained the same as in the previous years.
Researchers studied drilling wastes produced at two research wells near Morgantown and found they are well below federal guidelines for radioactive or hazardous waste.
A study shows that weather patterns tied to climate change may increase the severity of algal blooms in Chesapeake Bay as extreme rainfall cycles flush larger amounts of nitrogen from fertilizer and other sources into the Susquehanna River. The researchers found that a spike in rainfall can increase nitrogen levels in the bay even if the amount of fertilizer used on land remains the same, leading to explosive algae growth that poisons humans and wildlife, and devastates fisheries.
Penn State Extension Educator, Jim Clark, presented information on basic hydrology and where to go for drought monitoring information at a Drought Seminar for Potter County Farmers on Thursday, August 11, 2016.
Researchers developed an affordable way to monitor rivers and stream flow, 24/7, using open source products.
A new virus has been identified in association with a die-off of largemouth bass in Pine Lake in Wisconsin's Forest County. The previously unknown virus was isolated at the U.S. Fish and Wildlife Service's La Crosse Fish Health Center from dead fish collected by the Wisconsin Department of Natural Resources (DNR) during an investigation into a May 2015 fish kill in the northeastern Wisconsin lake.
Penn State Extension Water Educator, Jim Clark, and Extension Water Specialist, Bryan Swistock, presented a workshop for 61 Venango County Residents on Tuesday, August 2, 2016.
Penn State Extension Water Resources Educator, Jim Clark, assisted PA CleanWays of McKean County remove another two thousand tires from McKean County, filling two tractor-trailers on Saturday, July 23, 2016.
Project Learning Tree offers grants up to $1,000 to schools and youth organizations for environmental service-learning projects that link classroom learning to the real world. Students implement an action project they help design to green their school or to improve an aspect of their neighborhood’s environment. The deadline to apply is September 30, 2016 -- Funding will be distributed in December 2016.
A new draft report released Monday from the Department of Environmental Protection lists four miles of the Lower Susquehanna River as impaired for recreation, but not for protecting aquatic life as requested by the Fish and Boat Commission, the Chesapeake Bay Foundation-PA and other groups.
Thanks to global warming, waterways that make up important habitat for fish are likely to experience an increased frequency of such extreme conditions. Researchers wanted to know the impact of severe storms on fish populations that have to make sudden and unexpected trips downstream, away from their preferred habitat, to more hospitable waters.
For the most part, antibiotics play a positive role in the modern world. They help combat infection and keep us healthy. However, antibiotics often find their way into water streams and wastewater treatment plants while still biologically active. And that’s a problem for a variety of reasons.
The pitter patter of rain may induce you to quickly take dry refuge. Nature wants no such escape. Instead, she collects, funnels, and deposits water in some of the most innovative ways. Try a tree as your tutor and you will notice that essentially each tree is a microcosm of an entire watershed, moving water efficiently over its singular, vertically arranged landscape.
A common type of blue-green algae is finding it easy to adapt to Earth's rising CO2 levels, meaning blue-green algae -- of which there are many toxin-producing varieties -- are even more adept at handling changing climatic conditions than scientists previously supposed. Microbiologists point at implications for clean drinking water, swimming safety and freshwater ecosystems.
