U. S. EPA has conducted national surveys to determine the most frequently tested parameters used in citizen based voluntary monitoring programs. They are listed below and are also included in the administrative rules for the program. To ensure that data on these commonly sampled parameters is credible for its intended use the administrative rules identify some of the sampling and analytical methods suitable for Level 1 and Level 2 projects.
