•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.
