Runoff from pavement with coal-tar-based sealant is toxic to aquatic life, damages DNA, and impairs DNA repair, according to new research. Rainwater runoff collected as long as three months after coal-tar-sealcoat application caused 100% mortality to minnows and water fleas, which are part of the base of the food chain
The possibility of water resource contamination resulting from the use of horizontal drilling and hydraulic fracturing shale energy development is a large concern, even though it is not a common problem.
Groundwater professionals from across Pennsylvania gathered on May 6, 2015 at the Ramada Inn Conference Center in State College, PA for the 2015 Pennsylvania Groundwater Symposium. The symposium was again held during National Drinking Water Week in recognition of the importance of groundwater to both public and private drinking water supplies across Pennsylvania.
The U.S. Environmental Protection Agency (EPA) issued health advisory values that states and utilities can use to protect Americans from elevated levels of algal toxins in drinking water.
A medication commonly taken for Type II diabetes, which is being found in freshwater systems worldwide, has been shown to cause intersex in fish – male fish that produce eggs. The medication is found to be widespread in freshwater.
A worldwide study of the interplay between organisms and their environment bolsters the idea that greater biodiversity helps maintain more stable and productive ecosystems.
Project Learning Tree is proud to announce that we are now accepting applications for the next round of PLT GreenWorks! grants. Schools and community programs that wish to improve the environment are encouraged to apply. Grants up to $1,000 are available and funding will be distributed in January 2016. You must have attended a PLT professional workshop either in person or online to be eligible to apply.
For the first time, blacklegged (deer) ticks have now been observed in all 67 counties of Pennsylvania, according to researchers at The Department of Environmental Protection (DEP). The range expansion took place in just decades, as similar studies conducted in the mid-1960s found no specimens.
As our landscapes grow and develop, the health of our streams and rivers have been impaired. What we do on the land, or what we cover it with, affects the quantity (volume and velocity) and quality (pollutant levels) of the rainfall that enters our waterways; what many call stormwater.
The House Consumer Affairs Committee is scheduled to hold a hearing on House Bill 48 (Godshall-R-Montgomery) setting drinking water well construction standards (sponsor summary) on May 12.
Penn State Extension Water Resources Educator, Jim Clark, serves as Chapter Secretary and was a founding member in 2000, of the PA CleanWays Chapter in McKean County. In April of 2015, PA CleanWays of McKean County, an affiliate of Keep PA Beautiful, completed a cleanup on Pine Grove Road in Annin Township, along the banks of the Allegheny River.
Fish are the key ingredients in a new recipe to diagnose and restore degraded coral reef ecosystems, according to scientists.
The landscaping plants chosen by residents for their yards plays a much greater role in the diversity of native birds in suburban neighborhoods than do the surrounding parks, forest preserves, or streetside trees, say biologists.
A recent webinar sponsored by the Penn State Extension Water Resources team highlighted the ongoing work to develop the new Master Watershed Steward program in the state.
PA NRCS has developed two new publications to help employees and partners communicate the important differences between NRCS's nutrient management assistance products and the various types of state regulatory plans.
Insight into how large-scale deforestation could impact global food production by triggering changes in local climate has been gained by new research. In the study, researchers from the United States and China zero in on albedo (the amount of the sun's radiation reflected from Earth's surface) and evapotranspiration (the transport of water into the atmosphere from soil, vegetation, and other surfaces) as the primary drivers of changes in local temperature.
Consumers whose drinking water can be contaminated by the release of untreated wastewater after heavy rains face increased risk for gastrointestinal illness, according to a report. Many older cities such as Chicago have combined sewer systems -- along with 772 other communities, primarily in the Northeast, Great Lakes and Pacific Northwest, serving a total of 40 million people. While some cities are building infrastructure to handle sewage and runoff separately, other regions with combined systems depend on reservoirs to provide extra capacity during extreme rainfalls.
A new online, interactive tool for estimating atrazine concentrations in streams and rivers is now available.
Poop could be a goldmine -- literally. Surprisingly, treated solid waste contains gold, silver and other metals, as well as rare elements such as palladium and vanadium that are used in electronics and alloys.
A New Democratic Party Member of Parliament is calling on the Canadian government to list microbeads, tiny plastic flakes used in cosmetics, as a potential toxic substance. Health Canada claims the beads are safe for use as an additive, but this MP says they pose a danger to the aquatic environment. Researchers are warning that microbeads and plastic debris of all sizes could be a bigger environmental problem for the Great Lakes than previously thought.
