Drinking Water Nitrate Concentration News on Environmental XPRT

Nitrate concentrations of groundwater increasing in many areas of US

Nitrate is the most common chemical contaminant in the world’s ground water, including in aquifers used for drinking-water supply. Nitrate in drinking water of the United States is regulated by the U.S. Environmental Protection Agency (USEPA) because of concerns related to infant health and possible cancer risks. Use of man-made synthetic fertilizers has steadily increased since World War II, ...

Des Moines struggling with nitrates in water

Two rivers that supply water to 500,000 people in the Des Moines area show nitrate levels spiking to levels that make it unsafe for some to drink, a concentration experts haven't before seen in the fall that likely stems from especially wet weather in recent months. The utility that supplies Des Moines and most of its suburbs had workers blending river water with other sources to lower the ...

Drinking water wells vulnerable to contamination

New USGS groundwater studies explain what, when, and how contaminants may reach public-supply wells. All wells are not equally vulnerable to contamination because of differences in three factors: the general chemistry of the aquifer, groundwater age, and direct paths within aquifer systems that allow water and contaminants to reach a well. More than 100 million people in the United States ...

Well water should be tested annually to reduce health risks to children

Private well water should be tested yearly, and in some cases more often, according to new guidance offered by the American Academy of Pediatrics (AAP). Researchers at the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health, took a lead role in working with the AAP to develop these recommendations and draft a new AAP policy statement about the ...

Unintended energy impact from bioethanol production

Increasing crop production to meet demand for biofuels potentially increases the use of nitrogen fertilisers, which can lead to nitrate pollution in surface and groundwater. A new study is the first to consider the unintended extra energy needed to treat water to remove nitrate contamination in drinking water supplies. In the United States, the Renewable Fuel Standard1 (RFS) stipulates the ...

Nitrogen pollution measures need tailoring to specific areas to ensure cost-effective results

New research has shown that policy measures in Denmark have successfully reduced total nitrogen loading to 10 estuaries by 39% in recent decades. However, to fully meet the targets of the EU Nitrates Directive and comply with the EU Water Framework Directive in a cost-effective manner, further mitigation measures must be tailored and focused to particular areas. Increased use of nitrogen ...

Pesticides and pharmaceuticals influence riverbed communities of microbes

Changes in complex microbial communities known as ‘biofilms’ at the bottom of rivers can reveal the effects of pesticide and pharmaceutical pollution of river water, according to a recent study. Painkillers and anti-inflammatory drugs were found to have a significant effect on the structure and functioning of the biofilms. Human activities are contaminating surface waters with ...
