  • Why do water companies add phosphate?
  • Water companies treat water by adding phosphate to prevent the corrosion and metal leaching occurring in Drinking Water Distribution Systems (DWDS) (Mavropoulos et al., 2004; Gooddy et al., 2015).
  • What are phosphate products for potable water treatment?
  • Phosphate products for potable water treatment can be broadly classified into three groups: phosphoric acid, orthophosphates, and condensed phosphates. Phosphoric acid, orthophosphates, and condensed phosphates encompass a wide variety of chemical compounds having potential for potable water treatment applications.
  • Do consumers trust drinking water in the Netherlands?
  • Consumer trust in the Netherlands’ drinking water was sur-veyed in 2008 (VEWIN, 2008). Over 95% of the consumers fully trust the drinking water quality and its safety. The es-thetic quality of drinking water was compared to that of bot-tled (mineral or spring) water.
  • Does the Dutch drinking water regulation apply to small water supplies?
  • The Dutch drinking water decree (Staatsblad, 2001) generally applies stricter requirements for drinking water quality. Although the European directive allows exceptions for small supplies (less than 10 m3 water per day or 50 persons), the Dutch reg-ulations do not include this.
