This field manual is intended to serve as a field reference guide for the collection of water quality samples from surface water and ground water. More detailed information can be found in reference materials from the Arizona Department of Environmental Quality and other sources. Separate training should be provided prior to field water quality sampling.

The overriding objective of this manual is to provide consistent field sampling protocols for the numerous agencies and individuals who require water quality information. However, it is not intended to replace any sampling plan. The Spanish-language version of this manual also is available to help address emerging environmental sampling concerns along the U.S.-Mexican border. Increased water quality management along the border will require integrated sampling and analysis protocols, something that the production of this manual can foster.
