  • Effective drinking water disinfection

    The need for drinking water disinfection is as old as public water supply itself. Microbiological parameters for drinking water treatment include coliform bacteria and specific pathogenic species of bacteria, vira, and protozoan parasites.

By carrying out these projects in Vietnam, DHV is making an important contribution to 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 ...

  • Turning seawater into drinking water with sun and wind power

    A commercial-scale, seawater desalination plant powered by solar and wind energy that produces freshwater and dry salt has been designed by Spanish researchers. The new process does not discharge highly concentrated salty water back into the sea as a by-product, ensuring that there is little damage to the marine environment. Desalination plants extract freshwater from seawater and the technology ...
