Before wastewater reaches recipient waters, nutrients must be removed in order to avoid eutrophication and large algal blooms, which may result in serious damage to animal and plant life. Robert Almstrand at the Depertment of Chemistry and Molecular Biology at the University of Gothenburg, Sweden, has shown in his thesis that better removal of nitrogen from wastewater can be achieved by providing the bacteria that purify the water with alternating high and low levels of nutrients.
The grant for $234,713, given to the Oklahoma Department of Labor (ODOL), will be used for inspections and encouraging compliance with the Asbestos in Schools Program which is designed to protect the health of school children and other occupants as well as the community.
The costs to switch to numeric criteria for limiting nutrient pollutants in Florida waters are expected to exceed U.S. Environmental Protection Agency (EPA) estimates, says a new National Research Council report.
As the world population grows, the struggle to provide enough resources to people becomes paramount. Whether it is having access to a resource or having enough of it, nations will fight to gain control of supply. Of those resources, one of the most vital is water.
Last March, the world watched closely as Japan struggled to contain a series of equipment failures, hydrogen explosions and releases of radioactive materials at the Fukushima Daiichi Nuclear Power Plant.
A start-up from EPFL and CSEM is putting on the market a thermal regulator that uses neural networks to learn about your house as the seasons change, allowing for savings of up to 65 percent on fuel.
Waterways in remote, pristine tropical forests located in the Caribbean and Central America contain levels of nitrogen comparable to amounts found in streams and rivers flowing through polluted forests in the United States and Europe. This discovery by a Princeton University-led research team raises questions about how tropical forests might respond if they were to become exposed to additional nitrogen through water and air pollution.
Bus and truck companies could cut their fuel bills by more than 7 percent simply by training their drivers on more efficient driving techniques and offering a financial reward to those who improve fuel economy. A study published in the International Journal of Sustainable Society, suggests that training and financial reward improves efficiency by 7.3 percent whereas training or reward alone leads to about 5 percent savings.
As scientists continue the hunt for energy sources that are safer, cleaner alternatives to fossil fuel, an ever-increasing amount of valuable farmland is being used to produce bioethanol, a source of transportation fuel. And while land-bound sources are renewable, economists and ecologists fear that diverting crops to produce fuel will limit food resources and drive up costs.
City of Tulsa aggressively leading the country in providing for vehicles' easy switch to alternative, inexpensive fuels.
Past disturbances, such as logging, can obscure the effects of climate change on forest ecosystems. So reports a study just published in the Proceedings of the National Academy of Sciences. The paper, exploring nitrogen dynamics, found that untangling climate impacts from other factors can be difficult, even when scientists have access to decades of data on a forest's environmental conditions.
The final report summarizes impacts from the November 2007 oil spill and describes restoration projects, which trustees will begin to fund this spring.
Farmers in the U.S. and the European Union receive billions of dollars in government subsidies each year to make changes in their operations that will improve the environment. However, a new study by Paul Armsworth, assistant professor in ecology and evolutionary biology at the University of Tennessee, Knoxville, finds that these government programs may offer very poor value for money.
The Wildlife Conservation Society (WCS) applauds the efforts of Argentina’s Grupo Costa del Río Colorado cooperative in its first U.S. sale of “green” cashmere, produced through a system of sustainable practices that protects guanacos, rheas, Andean cats, and other wildlife of the windswept expanse of the Patagonian Steppe.
A Cornell study's contention that hydraulic fracturing would be worse for climate change than burning coal is being challenged by another study, also by Cornell researchers.
The U.S. Environmental Protection Agency (EPA) is encouraging individuals and community groups in the U.S. Virgin Islands to apply for grants that will allow “citizen scientists” to collect information on air and water pollution in their communities and seek solutions to environmental and public health problems.
The U.S. Environmental Protection Agency (EPA) has proposed a plan to clean up contaminated sediment, soil and debris in streams and in an area near lagoons in which industrial wastewater was stored at the Universal Oil Products Superfund site in East Rutherford, N.J. The proposed cleanup plan will eliminate the threat of contaminants spreading off the site through the streams that carry water into Berry’s Creek, located on the eastern border of the site. The EPA is simultaneously overseeing a comprehensive study of the site to determine what other measures may be necessary to address the contamination.
The U.S. Environmental Protection Agency (EPA) will provide up to $15 million in funding for training and technical assistance to small drinking and wastewater systems, defined as systems that serve fewer than 10,000 people, and private well owners.
As Asian countries develop, they are emitting more ozone precursors that pollute surface level air. Many studies have documented this pollution being carried by air currents to the western United States.
Polar ecosystems could be at risk from the spread of toxic cyanobacteria if the climate continues to warm, say scientists.
