Drinking water standards include lists of parametric values, and also specify the sampling location, sampling methods, sampling frequency, analytical methods, and laboratory accreditation . In addition, a number of standards documents also require calculation to determine whether a level exceeds the standard, such as taking an average.
The regulations cover pollutants for which there are approved analytical testing methods. EPA has published many methods in its regulations, [ 4 ] and has approved the use of other methods published by peer-reviewed sources, such as Standard Methods. [ 5 ]
