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.
Researchers have uncovered previously hidden sources of ocean pollution along more than 20 percent of America's coastlines. The study offers the first-ever map of underground drainage systems that connect fresh groundwater and seawater, and also pinpoints sites where drinking water is most vulnerable to saltwater intrusion now and in the future.
To assist Native American and Alaska Native communities, U.S. Geological Survey (USGS) scientists developed a guide to evaluate algal blooms for the presence of cyanobacteria that are known to produce a variety of toxins.
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.
Mosquitoes in the Aedes family can transmit not only the Zika virus, but also dengue and chikungunya. Travelers visiting regions affected by these diseases should take steps to protect themselves, warn experts.
The Department of Environmental Protection published notice in the July 30 PA Bulletin it is making available a copy of the draft 2016 Integrated Water Quality Monitoring and Assessment Report for public comment.
A new report from the Pennsylvania Department of Environmental Protection (DEP) lists four miles of the Susquehanna River as impaired for recreation. The recreation impairment listing joins an impairment for fish consumption for the Susquehanna River, though the listings are not related to smallmouth bass populations in the river. The report also sets forth a groundbreaking protocol to scientifically assess a large river system.
The Pennsylvania Department of Environmental Protection declared a drought watch in 34 counties and a drought warning in one county on August 2, 2016. Rainfall deficits of up to 6 inches during the past three months have resulted in unusually low streamflows, dried up water wells or springs, and withered crops across the affected counties.
The PA Environmental Council Tuesday unveiled a new website-- WaterResourcespa.org-- that allows the public to identify water quality impaired streams, illegal dumpsites, areas covered by stormwater management plans and much more.
Penn State Extension Water Educator, Jim Clark, and Extension Water Specialist, Bryan Swistock, presented a workshop for Elk County Residents on Tuesday, July 26, 2016. The participants all had their water tested at the Penn State Ag Analytical Water Lab for several health related parameters, such as lead.
Groundwater discharge that flows into the Upper Colorado River Basin varies in response to drought, which is likely due to aquifer systems that contain relatively young groundwater, according to a new study.
Penn State Extension educators will be visiting hundreds of farms in the next month to follow up on a survey Pennsylvania farmers received earlier this year asking about conservation practices they have adopted to promote water quality and soil health.
Pennsylvania has led the nation in confirmed cases of Lyme disease from 2012–2014, according to the most recent data available from the Centers for Disease Control and Prevention.
Private wells and on-site wastewater systems don’t come with a monthly or quarterly bill, but homeowners should budget for routine maintenance and eventual repairs. Proper construction and regular inspection and maintenance can help put off major expenses, but wells and septic systems do have a lifespan.
Corrosive groundwater, if untreated, can dissolve lead and other metals from pipes and other components in water distribution systems. Two indicators of potential corrosivity—the Langelier Saturation Index (LSI) and the Potential to Promote Galvanic Corrosion (PPGC)—were used to identify which areas in the United States might be more susceptible to elevated concentrations of metals in household drinking water and which areas might be less susceptible.
How much water does your lawn really need? A study re-evaluated lawn watering recommendations by measuring water use by lawns in Los Angeles. The standard model of turfgrass water needs, they found, lacked precision in some common urban southern California conditions, like the Santa Ana winds, or in the shade.
Researchers are refining a natural, low-cost process that will help remove some of the most abundant pollutants, such as iron, from mine-contaminated water.
Using a first-of-its-kind, watershed-scale experiment, researchers demonstrate beaver dam analogs in the Bridge Creek Watershed of north central Oregon's John Day Basin foster natural beaver activity, which benefits the area's threatened steelhead trout population.
Nuisance algae growth is one of the most common problems reported by pond and lake owners in Pennsylvania. Of greatest concern are algae blooms that are caused by microscopic blue-green algae which are capable of producing toxins, known as harmful algal blooms or “HABS”. These algal toxins can sicken animals and humans that contact the water and may cause the death of fish or other aquatic life.
Stone piles are a visible blight on the landscape. Moving rocks harms aquatic habitat. Piling stream rocks is against the rules in natural areas and most parks.
