Study finds bladder cancer risk was associated with water intake among participants with a history of private domestic well use. The trend was significant for participants who used shallow dug wells exclusively—a well type that typically has low arsenic concentrations but may have had higher concentrations historically.

A recent U.S. Geological Survey (USGS) assessment of more than 20,000 wells nationwide indicates that groundwater in 25 States and the District of Columbia has a high potential for being naturally corrosive. The States with the largest percentage of wells with potentially corrosive groundwater are located primarily in the Northeast, the Southeast, and the Northwest

Knowing what kinds of aquatic plants may be growing in a pond is the first step to obtaining an ideal balance of plant life to meet the pond's intended use. This new Learn Now video looks at the four categories of pond plants, and some of the most common aquatic plants that are found in Pennsylvania.

The pastoral image of cows drinking from a stream has a hidden story. Pennsylvania has long been home to a robust agriculture industry, where cows, hay bales, and horse-drawn plows dot rolling hills of grasses and grain. For those acquainted with these scenic landscapes and the hard-working farmers who maintain them, the pastoral image of lazy dairy cows drinking from a trickling stream is a familiar one. To the untrained eye, it seems a natural ornament of bygone days.

The National Lakes Assessment (NLA) is a statistical survey of the condition of our nation's lakes, ponds, and reservoirs. It is designed to provide information on the extent of lakes that support healthy biological condition and recreation, estimate how widespread major stressors are that impact lake quality, and provide insight into whether lakes nationwide are getting cleaner.

The Pennsylvania Department of Environmental Protection (DEP) has placed four more counties on drought warning status following a meeting today of the Commonwealth Drought Task Force. While recent precipitation over the past few weeks has helped dry conditions in the eastern part of Pennsylvania, the central part of the state still has persistent 90-day precipitation deficits of up to 4 inches from normal as well as low groundwater and stream levels.

Over half of Pennsylvania residents rely on groundwater for at least part of their drinking water. Groundwater is also the predominant source of water used for agriculture, commercial and mining activities in the state. While Pennsylvania has abundant groundwater resources, it is critical that they be properly protected from pollution associated with land use activities. Use of pesticides represents one such groundwater threat.

Chesapeake Bay Program partners are welcoming the review of new high-resolution land use data for all 206 counties in the Chesapeake Bay watershed. The data will inform the partnership’s next generation of models used to estimate nutrient and sediment loads and to credit efforts to reduce those pollutants from draining into the nation’s largest estuary.

Study finds life under the ice is vibrant, complex and surprisingly active - As long as ecologists have studied temperate lakes, the winter has been their off-season. It's difficult, even dangerous, to look under the ice, and they figured plants, animals and algae weren't doing much in the dark and cold anyway. But an international team of 62 scientists looking at more than 100 lakes has concluded that life under the ice is vibrant, complex and surprisingly active. Their findings stand to complicate the understanding of freshwater systems just as climate change is warming lakes around the planet.
