To develop a sampling design or monitoring plan, the following
should be considered:
Monitoring objectives, including consideration of geophysical
setting, meteorology, types and characteristics of sources, and
existing monitoring programs.
Data quality objectives needed to answer questions to be asked
of the data (i.e., how precisely or accurately do the questions
need to be answered?).
Options for what, when, where, how frequently, and for how long
to monitor; these are related to the selection of appropriate
monitoring equipment and laboratory analyses.
Data quality assurance and validation approach, including
collocated data requirements, QA programs for analytical
laboratories, and data validation guidelines for ambient data.
Options for data analysis and exploration, including available
tools, data analyses, data needs, and training needs.
