Public Water Systems (PWS), regulated by the United States Environmental Protection Agency (USEPA), provide drinking water to 90% of Americans. Water systems and laboratories testing drinking water for Safe Drinking Water Act (SDWA) compliance must be certified and must use USEPA approved methods, which are developed by the USEPA, other government agencies, universities, consensus method organizations, water laboratories, and instrument manufacturers.. Ensuring a safe water supply requires skilled technicians with an understanding of current and evolving regulations, as well as the latest instrumentation needed to ensure testing standards are being met. This paper provides an introduction to drinking water sampling, contaminants tested, sample preservation, and instruments used to measure contaminants in drinking water.
