Sampling is the single most important activity for every project. The purpose of sampling is to identify the goals of the project, to answer specific questions, or to develop a hypothesis to test. While it is normal for clients to be upset when they encounter a suspected case or an outbreak, avoid taking random samples without understanding how the data will be used and who could ultimately see the results first.
Here are some key questions to consider that will help you focus your sampling efforts:
It is important to take as many samples as necessary to obtain sufficient data to answer your questions. Every sampling location should provide data to answer a question however, avoid taking more samples than necessary. Understand that one sampling point or one sampling event will not constitute a representative number of samples and will not pass a legal challenge. The purpose of sampling will vary according to different project goals so adjust your sampling strategies accordingly. Use the “Where to Look” and “Sample Locations” sections to help focus your activities.
