  • Nitrate Contamination in Groundwater Worsens in California Farm Areas

    A new study claims that nitrate pollution in drinking water supplies near California’s Central Valley farming communities has worsened in recent decades and will continue to spread, reports the LA Times. UC Davis scientists analyzed groundwater data from the southern San Joaquin and Salinas valleys and concluded that even if all farming operations stopped immediately, nitrates would stay in ...

  • Nitrate and the U.S. EPA

    The U.S. EPA initiated the Federal Water Pollution Control Act  in 1948 to regulate contaminants in surface waters - which later expanded in 1972 to form the Clean Water Act (CWA). Nitrate is one of the primary contaminants regulated by the U.S. EPA under the CWA as well as the Safe Drinking Water Act (SDWA). The maximum contaminant level set by the ...

  • 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 ...

  • 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, ...

  • Iowa copes with nitrate surge in drinking water

    For much of last year, Iowa's most pressing agricultural problem was a drought that baked farm fields and parched crops, turning them brown and crumbly. Then the skies finally opened up, providing one of the soggiest springs on record. But the rain has created a new, unexpected problem: The deluge is washing fertilizer off the farms and into rivers that provide drinking water to much of the ...

  • 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 ...

  • Water well owners should check water periodically for bacteria, nitrate

    Bacteria and nitrate are widespread in the environment, so every household water well owner should regularly test their water to make sure no health risk exists, the National Ground Water Association recommended today. While most bacteria found in water do not cause disease, disease-causing bacteria called pathogens can exist in well water given the right circumstances, NGWA said. Nitrate is not ...

  • 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 ...

  • Fertilisers linked to contaminated drinking water in Evros, Greece

    In a new study, samples of drinking water from the north-east of Greece have been found to exceed European limits for nitrates, sulphates and phosphates - chemicals that are linked to health problems such as reproductive disorders and cancer. The research has produced a map of the Evros area showing the location of 64 water sampling sites and found that pollution levels are highest in areas with ...

  • Study finds contaminants in California public-water supplies

    Nearly one-fifth of the raw groundwater used for public drinking water systems in California contains excessive levels of potentially toxic contaminants, according to a decade-long U.S. Geological Survey study that provides one of the first comprehensive looks at the health of California's public water supply and groundwater. One of the surprises in the study of 11,000 public supply wells ...
