  • 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 ...
