Laboratory or sample-preparation areaSite Type ⤴
A site where some types of quality-control samples are collected, and where equipment and supplies for environmental sampling are prepared. Equipment blank samples are commonly collected at this site type, as are samples of locally produced deionized water. This site type is typically used when the data are either not associated with a unique environmental data-collection site, or where blank water supplies are designated by Center offices with unique station IDs.
