High concentrations of nutrients, like nitrogen and phosphorus, from agricultural sources are one cause for the degradation of the Chesapeake Bay. One method to potentially reduce these nutrient sources is to alter the levels of nutrients in feed use for livestock.
Conventional methods of stock monitoring are unsuitable for certain fish species. For example, the infestation of an area with invasive Ponto-Caspian gobies cannot be identified in time by standard methods. Researchers have now developed a simple, effective and cost-efficient test for these introduced non-native fish.
U.S. Geological Survey (USGS) scientists detected microcystin—an algal toxin—in 39 percent of 75 streams assessed in the southeastern United States. These results will inform and become part of a larger, systematic national survey of algal toxins in small streams of the United States.
The water crisis in Flint, Michigan shines a much-needed spotlight on public drinking water quality. Public outrage surrounding this crisis is understandable when regulations and standards intended to protect public health are sacrificed to save money.
Researchers have developed a new way to prioritize investigations on the environmental impacts of the estimated 1500 active pharmaceutical ingredients currently in use.
Recent developments in Flint, Michigan have highlighted concerns of lead in drinking water. Lead is an extremely toxic metal that can cause serious health effects, especially in children.
Excess stormwater is a growing problem in Pennsylvania and across the country, contributing to water pollution, flash floods and other issues. To help youth and adults understand and reduce the impacts of stormwater, Penn State Extension has launched a new curriculum titled "Rain to Drain — Slow the Flow."
An analysis of public water systems in Pennsylvania cities with high lead exposure rates shows that drinking water is not the source of the lead. Out of the more than 150 public water systems reviewed by the Pennsylvania Department of Environmental Protection (DEP) none had exceeded EPA standards for lead in the drinking water. The water systems tested serve more than 6 million people – nearly half of the residents of the state.
A Temple University researcher's recently published study might illuminate a previously unclear relationship between private water wells in Canada and an acute stomach bug -- findings that could have implications in the Keystone State.
New 'pulse-shunt' concept explains key role of infrequent, but critical, events. Heavy weather events cause an inordinate amount of organic material to bypass headwater systems, say researchers, pushing them downstream into larger rivers and coastal waters and inland basins -- with profound implications for water quality through the watershed.
New scientific research from the U.S. Geological Survey (USGS) details how landfill leachate, disposed from landfills to environmental pathways, is host to numerous contaminants of emerging concern (CECs).
For Pennsylvanians watching the lead contamination problem in Flint, Michigan, and wondering whether their drinking water is safe, one water-resources specialist at Penn State University says residents with private wells, especially, should consider having their water tested.
Let's forget about the climate for a minute. Largely hidden from public view, another global change is causing increasing disruption. Residues of medicines in water can kill aquatic animals and play havoc with their food web and reproductive cycle. An international team of researchers makes an urgent case for better wastewater treatment and biodegradable pharmaceuticals.
Researchers have found clear evidence that communities rich in species are substantially healthier and more productive than those depleted of species, once complicating factors are removed.
There are many types of water treatment methods, and no one treatment solves all problems. Here we examine one sort of treatment that is commonly used by well owners and public water customers, the activated carbon filter.
National events about lead exposure have generated new concerns for Pennsylvanians related to the safety of their homes and water. The Wolf Administration takes the issue of lead exposure very seriously and state agencies will continue to work together on their coordinated response to address lead exposure in communities across the commonwealth. The Departments of Health (DOH) and Environmental Protection (DEP) both work diligently to protect children from lead exposure and have many resources available for residents to learn more and take action on lead.
On the strength of the commonwealth’s rebooted strategy to improve clean water in the Susquehanna River watershed, extending into the Chesapeake Bay, announced last month, the U.S. Environmental Protection Agency (EPA) has restored $3 million in program funding to the Pennsylvania Department of Environmental Protection (DEP).
By the latter half of this century, toxic algal blooms like the one that cut off drinking water to the city of Toledo in 2014 will no longer be the exception, but the norm, a study suggests.
The January 6 Resource newsletter from the Department of Conservation and Natural Resources reviews the agency’s accomplishments in 2015.
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.
