This article focuses on problems that can occur within the distribution system and the point of use (POU) devices that can be used to address these problems. The causes of contamination discussed in the article include: formation of disinfection byproducts (DBPs); distribution system repairs and replacement; hydraulic surges; power outages; fire flow; and, backpressure. The burgeoning growth of the bottled water industry is mentioned, along with a variety of technologies used in POU devices that include sediment filters, submicron filtration and activated carbon systems, and disinfection systems. The article also discusses the costs of using POU devices and who should be responsible for installing and maintaining the devices.
