    A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. This U.S. Geological Survey textbook discusses statistical methods appropriate for analysis of water resources data. You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more. Abstract: The U.S. Geological Survey maintains a quality-assurance program based on the analysis of reference samples for its two water-analysis laboratories located in Atlanta, Georgia, and Denver, Colorado. Reference samples containing inorganic constituents are prepared at the U.S. Geological Survey's Ocala, Florida office and disguised as routine samples, and sent daily to each laboratory Cited by: 4. of Soil Water and Water in Plant Matter; RSIL Lab Code Chapter 19 of Section C, Stable Isotope-Ratio Methods Book 10, Methods of the Reston Stable Isotope Laboratory.

Geological Survey National Water Quality Laboratory; determination of the total phosphorus by a Kjeldahl digestion method and. Water samples for trace-metal determinations routinely have been prepared in open laboratories. For example, the U.S. Geological Survey method I (Extraction Procedure, for Water- Suspended Sediment) is performed in a laboratory hood on a laboratory bench without any special precautions to control airborne contamination.

This method tends to be contamination prone for several trace. This section of chapter 5 of the National Field Manual for the Collection of Water-Quality Data (NFM) describes the field procedures for collecting small-volume samples using a syringe-tip filtration method.

Analytical recovery is the concentration of an analyte measured in a water-quality sample expressed as a percentage of the known concentration added to the sample (Mueller and others, ).

Analytical recovery (hereafter referred to as “recovery”) can be used to understand method bias and variability and to assess the temporal changes in a method over time (Martin and others, ).
