As people convert natural landscapes to human-tailored ones, we change the cycling of water and carbon dramatically. Across the United States, water supplies are under increasing pressure as populations grow. Forests and soils that were once a sink for atmospheric carbon can become sources as the natural landscapes are disturbed.
A new presentation developed by Penn State’s Pesticide Education Program and Water Resources Educator Jim Clark has been used many times around the state this winter at meetings for core pesticide credits required by applicators needing to keep their pesticide license current.
Penn State Extension water resources educators conduct workshops on home drinking water supplies throughout Pennsylvania.
Adaptation to new risks: A vital necessity for development policies - The current instability and unpredictability of the world water cycle is here to stay, making society's adaptation to new risks a vital necessity when formulating development policies, a UN expert warns. He says long-term water cycle stability 'won't return in the lifetime of anyone alive today.
Research seeks to evaluate on-farm best management practices to prevent pathogens from entering streams. This source water protection strategy may represent a cost-effective, sustainable way to protect drinking water.
Urbanization in the Chesapeake Bay watershed has increased stream discharge, the frequency of flood-plain inundation, and the transport of nutrients (such as nitrogen and phosphorus) and sediment to streams and, ultimately, to the bay. Understanding the effects of the abundance, composition, and location of vegetation on flood-plain functions such as nutrient cycling and sediment trapping can aid in the development of effective best management practices that help improve the quality of water entering the bay.
Expanding the use of recycled water would reduce water and energy use, cut greenhouse gas emissions and benefit public health in California — which is in the midst of a severe drought — and around the world. A new study found that recycled water has great potential for more efficient use in urban settings and to improve the overall resiliency of the water supply.
Scientists have recently discovered that fish in the northeastern U.S. are changing gender – and it’s not due to an identity crisis. A new study published in Ecotoxicology and Environmental Safety finds that male fish are turning into females – a phenomenon known as intersex.
April 22 marked the 46th anniversary of Earth Day. To celebrate, here are 10 simple things every Pennsylvanian can do to to protect the environment and your health.
The Secretaries of the departments of Environmental Protection and Conservation and Natural Resources joined the PA Environmental Council Tuesday in honoring the 13 recipients of the Governor’s Awards for Environmental Excellence at a dinner in Harrisburg.
Harnessing an invasive fish species sounded like a promising conservation tool to help reverse the destruction wreaked by zebra mussels on endangered native mollusks in the Great Lakes -- except that it won't work, says an ecologist.
Researchers show the link between exposure to pharmaceutical contaminants and consumption of fresh produce grown in reclaimed wastewater-irrigated soil. A new study shows that eating vegetables and fruits grown in soils irrigated with reclaimed wastewater exposes consumers to minute quantities of carbamazepine, an anti-epileptic drug commonly detected in wastewater effluents.
People boating and fishing on the Chesapeake last year kept noticing something they don’t often see — clear water.
In celebration of Earth Day, Penn State Extension Educator, Jim Clark, helped to organize the PA CleanWays of McKean County, an affiliate of Keep Pennsylvania Beautiful, successful highway collection on Saturday, April 23, 2016.
Harmful algal blooms dangerous to human health and the Lake Erie ecosystem--such as the one that shut down Toledo's water supply for two days in 2014--could become a problem of the past. Scientists have reported on approaches to reduce harmful algal blooms on Lake Erie.
Friday, April 22, 2016, will be the 46th year for the annual “Earth Day” event. This event has encouraged individuals and communities to organize illegal dump cleanups, tree planting events, and recycling projects. Cleaning up your environment will beautify the earth, but it also will go a long way to protect important groundwater resources flowing under our feet.
The economic and ecological impact of invasive species in the Great Lakes has been dramatically underestimated, research suggests. In fact, according to researchers, a single non-native species in a single inland lake has racked up $80 million to $163 million in damage.
A new method to track how wetlands in Eastern Washington behave seasonally has been developed by scientists, which will also help monitor how they change as the climate warms.
Homes in rural and suburban areas often rely on private wells for the household water supply and on-lot septic systems for wastewater management. A homebuyer may not notice problems with these essential systems prior to purchase without proper inspections.
GroupGAP is a new food safety certification option that will increase opportunities for the entire industry to supply and buy GAP-certified produce. This robust certification process addresses certain challenges in complying with food safety audits, and meets the demands of the retail, food service, and institutional buying community. The GroupGAP Audit Program will begin April 4, 2016.
