  • 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 ...

  • Radioactive contaminants removed from water

    A combination of forest by-products and crustacean shells may be the key to removing radioactive materials from drinking water, according to researchers from North Carolina State University. Pawlak and fellow researchers found that the new material, which forms a solid foam, has applications beyond radioactive materials and can also remove salt from sea water. “As we’re ...

  • USGS report `contaminants in groundwater used for public supply` released
