Nitrate in Lake Superior: On the rise
Nitrate levels in Lake Superior, which have been rising steadily over the past century, are about 2.7 percent of the way toward making the lake's water unsafe to drink, according to a study by University of Minnesota (UMN) researchers. view more (2007-06-06)
ORNL study finds rivers play part in removing nitrogen
Tiny organisms play a powerful role in removing nitrate, a form of nitrogen pollution caused by human activity, in streams, according to a study by a team led by Oak Ridge National Laboratory and published in Nature. view more (2008-03-13)
New regulations tighten controls on restricted chemicals
The Government of Canada is taking action to better control the sale of chemicals that can be used to make explosives. The Honourable Gary Lunn, Minister of Natural Resources, and the Honourable Stockwell Day, Minister of Public Safety, today announced that new regulations for these chemicals, known as explosives precursors, will be implemented... view more...

Is Your Drinking Water Safe?
Lake Bloomington is a major source of drinking water for residents of Bloomington, IL, and has a history of nitrate concentrations that exceed safe levels. Because Lake Bloomington has a record of elevated nitrate levels, local residents are concerned over their drinking water quality. view more (2008-02-29)
Drinking water in Gaza Strip contaminated with high levels of nitrate
Palestinian and German scientists have recommended to the authorities in the Gaza Strip that they take immediate measures to combat excessive nitrate levels in the drinking water. view more (2008-08-15)
Waddenzee fresher than ever
The seawater in the Waddenzee is becoming fresher. More river water is reaching the Waddenzee via the outlet sluices of the IJsselmeer Dam. This is the conclusion of Dr Hendrik van Aken from the Netherlands Institute for Sea Research. Along with the fresh water, more nitrate and phosphate are entering the Waddenzee. During the past 140 years the... view more... (2002-09-11)
Nitrate Concentrations of Ground Water Increasing in Many Areas of the United States
Nitrate is the most common chemical contaminant in the world's ground water, including in aquifers used for drinking-water supply. view more (2008-09-18)
Sleaford groups consulted on water use futures
Representatives of civic groups and local council members have been invited to a meeting on Monday 1st November to discuss how they see land and water uses in the Slea catchment changing in the future. The meeting is being organised by Sleaford Development Group at the Solo Club, Seaford and will brief those attending about a study investigating... view more... (2004-10-29)
FLUCTUATIONS IN BIOLOGICAL PRODUCTION IN THE EQUATORIAL PACIFIC UNDERTHE EFFECT OF EL NINO
A region of the western equatorial Pacific, the Pacific warm pool, has exceptionally warm surface waters (an average 28.5°C) which have low salinity and are oligotrophic (nutrient-poor). At the Equator the Eastern edge of this pool comes into contact with cooler water (24°C on average) which is saline and nutrient rich (especially in... view more... (1999-05-11)
Tree Species Composition Influences Nitrogen Loss From Forests
Throughout the world, nitrogen compounds are released to the atmosphere from agricultural activities and combustion of fossil fuels. view more (2009-03-17)
Large source of nitrate, a potential water contaminant, found in near-surface desert soils
A UC Riverside-led study in the Mojave Desert, Calif., has found that soils under "desert pavement" have an unusually high concentration of nitrate, a type of salt, close to the surface. Vulnerable to erosion by rain and wind if the desert pavement is disrupted, this vast source of nitrate could contaminate surface and groundwaters,... view more... (2008-03-03)
Two novel species of bacteria isolated from oil wells
Oilfields usually represent extreme environments, where physicochemical conditions appear at first sight to be generally unsuitable for living organisms to develop. However, these environments, usually poor in nitrates and oxygen, harbour a rich diverse community of microorganisms. The most widely represented and best-known types are... view more... (2004-11-23)
Small streams mitigate human influence on coastal ecosystems
Healthy streams play a major role in minimizing the amount of human-generated pollutants, such as nitrogen, that are delivered downstream. view more (2008-03-13)
Research shows a daily does of beetroot juice can beat high blood pressure
Researchers at Barts and The London School of Medicine have discovered that drinking just 500ml of beetroot juice a day can significantly reduce blood pressure. The study, published online today in the American Heart Association journal Hypertension, could have major implications for the treatment of cardiovascular disease. view more (2008-02-06)
Bug hotels to treat toxic landfill run-off
A novel way to treat the noxious liquid that leaches out of landfill sites, using ‘bug hotels’, is being investigated by research engineers. Bug hotels are artificial havens for nitrogen-hungry bacteria, created by providing them with a comfortable habitat, warmth and food. The landfill leachate can be pumped through these... view more...

Alternative farming cleans up water
Although the addition of nutrients to soil helps to maximize crop production, fertilizer can leach nutrients, polluting the water supply. view more (2007-07-20)
Brewing a blast-less fertilizer
Down in the green, rolling hills and farmlands around Lexington, Kentucky, Darrell Taulbee can be found mixing up a batch of his homegrown fertilizer. But he's not looking to grow a better Big Boy or distill a smoother bourbon, he tells us. view more (2007-09-06)
Pitt professor says harmful byproducts of fossil fuels could be higher in urban areas
Nitrogen oxides, the noxious byproduct of burning fossil fuels that can return to Earth in rain and snow as harmful nitrate, could taint urban water supplies and roadside waterways more than scientists and regulators realize. view more (2007-10-23)
Scientists show that streams are critical to preservation of oceanic coastal zones
The plight of the world's oceans is dire, according to recent studies, through insults from human-derived activities depopulating and damaging reefs, altering coastlines, and creating pollutants, such as nitrogen runoff from terrestrial watersheds. view more (2008-03-13)
Nutrients in water may be a bonus for agriculture
Agriculture producers may find they don't have to bottle their water from the Seymour Aquifer in the Rolling Plains to make it more valuable, according to Texas AgriLife Research scientists. view more (2008-11-25)
