• The Environmental Protection Agency (EPA) is responsible for monitoring of analytical standards used for environmental analysis in the USA.
• Much of this analysis is applied to the testing of water supplies for the presence of potentially harmful chemicals.
• These chemicals include pesticides, herbicides and polycyclic aromatic hydrocarbons. (PAH)
• The collection and processing of these water samples has been controlled by defining the type of vials used for this stage of the analysis.
• The EPA Vials are defined by their size, volume and their degree of cleanliness.
• These EPA Vials are also referred to as VOA (Volatile Organic Analysis) vials.
