SAMPLING DATA QUALITY
• The aim of a sampling program is to determine :  1) the key high concentration
areas in the site, 2) find the most sensitive
organisms, 3) then sample representatively.
• The analytical procedure will take the samples from the site and generate data of
a known quality with an accurate estimate
of errors associated with the sampling,
handling and analysis.
Quality assurance: an overall procedure that ensures defined quality standards are met.
Quality control: the controls which ensure
that the quality of analyses are being met.
