SEAN FQ monitoring SOP 2: Data Evaluation and Grading version 1.0
Nagorski S, Sergeant CJ, Johnson W, Moynahan B. SEAN FQ monitoring SOP 2: Data Evaluation and Grading version 1.0. NPS SEAN. Juneau, Alaska
After raw freshwater water quality data is collected in the field, data are evaluated by the Park and Project Leads for accurate transfer of data from the sonde to the handheld data display to the computer (SOP 3). After this initial evaluation, erroneous values are flagged and remaining data are quality-graded (Poor/Fair/Good/Excellent). This SOP describes which raw values will be flagged as outliers and prescribes a method for grading the quality of remaining data. Generally, USGS guidelines and standard procedures for water quality monitoring (Wagner et al. 2006) are followed, with some modifications required by logistical constraints.
