drinking water nitrate concentration News

  • 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, ...

  • Aqwise developing advanced biological treatment system for drinking water nitrate contamination

  • 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. 90 per cent of their water samples were found to contain nitrate concentrations that were between two and eight times higher than the limit recommended by the World Health Organization (WHO), say the researchers from ...

  • 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 ...

  • Funding for safe drinking water left unused

     The recent revelation that nearly half a billion dollars in federal funding for safe water has gone unspent by the State of California offers one more strong incentive for residents to install Final Barrier protection in their own homes, the Water Quality Association states. "While we rely on public agencies for initial treatment, the best way to ensure safe drinking water is by ...

  • Studies reveal why drinking water wells are vulnerable to contamination

  • Water pollution is decreasing but a lot remains to be done

    Water pollution caused by nitrates has decreased in Europe over the past two decades, but agricultural pressures are still putting water resources under strain. The latest Report on the implementation of the Nitrates Directive reveals that nitrates concentrations are slightly decreasing in both surface and groundwater and sustainable ...

  • Warwick, Lititz Receive EPA Award for Protecting Waters

    The U.S. Environmental Protection Agency today honored two Lancaster County, Pa. communities for protecting sources of drinking water used by more than 20,000 people. EPA Regional Administrator Shawn M. Garvin presented the agency’s 2012 regional Source Water Protection Award to the Warwick Township Municipal Authority and the Borough of Lititz at a ceremony at the Warwick Municipal Office. ...

  • 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 ...

  • World Water-Tech North America Summit Approaching

    The second annual World Water-Tech North America Summit, the fifth event in the World Water-Tech series, gathers the key stakeholders from every part of the water value chain. Hosted by Rethink Events and WaterTAP Ontario, the event provides a dynamic meeting place for the growing international water-tech community. World Water-Tech North America will feature ...

  • 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 ...

  • Capillary electrophoresis method according to EPA 6500 and ASTM D6508-10

    Lumex Instruments introduces a capillary electrophoresis method for determination of inorganic anions; fluoride, bromide, chloride, nitrite, nitrate, ortho-phosphate, and sulfate in drinking water, wastewater and ground water according to EPA 6500 and ASTM D6508-10 test methods. This test method is applicable for ...

  • Contaminants in US groundwater

    According to a new study by the USGS, more than 20% of untreated water samples from 932 public wells across the US contained at least one contaminant at levels of potential health concern. About one-third of the US population receive their drinking water from such a system. The USGS study (Contaminants in Groundwater used for ...

  • Study: Two major U.S. aquifers contaminated by natural uranium

    Nearly 2 million people throughout the Great Plains and California live above aquifer sites contaminated with natural uranium that is mobilized by human-contributed nitrate, according to a study from the University of Nebraska-Lincoln.

  • 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.
