  • Industry Sections


    WQA Sections provide opportunities for members of a particular membership segment to meet with peers to provide input and share their expertise.

  • Silver Fact Sheet


    Biologically, silver is a nonessential, non-beneficial element to humans. There are no scientific studies to show adverse health due to its presence in drinking water from natural sources. However, because of its bactericidal abilities, silver is used as a water bacteriostat in carbon containing water filters. The silver is deposited onto the carbon granules to…

  • Magnetics Report


    The content of the following report has been prepared by a special task force established by the Water Quality Association and represents the review by the members of the task force of a bibliography of scientific papers and information generally available to the public or released by the authors themselves. The views of the individual…

  • Cadmium Fact Sheet


    Cadmium occurs naturally in zinc, in lead and copper ores, in coal and other fossil fuels, in shales and is released during volcanic action. These deposits can serve as sources to ground and surface waters, especially when in contact with low total dissolved solids (TDS) and acidic waters. Major industrial releases of cadmium are due…

  • Copper Fact Sheet


    Copper is a metallic element that is essential to human health. Too little is unhealthy and too much can lead to copper poisoning. The body cannot synthesize copper so the human diet must supply regular amounts for absorption. The daily requirement is about 2 mg of copper intake per day to maintain a balance of…

  • Nitrites/Nitrates Fact Sheet


    Most nitrogenous materials in natural waters tend to be converted to nitrate, so all sources of combined nitrogen, particularly organic nitrogen and ammonia, should be considered as potential nitrate sources. Primary sources of organic nitrates include human sewage and livestock manure, especially from feedlots. The primary inorganic nitrates which may contaminate drinking water are potassium…

  • Trends Report: Performance Reduction Standards


    This report investigates countries we are aware of discussing performance/reduction standards requirements as it relates to drinking water treatment units through regulations or other initiatives.
