QUALT1

Character (A15)

15-digit character variable that contains data-quality flag codes for parameters underlined with asterisks (*******) in the file header

aVariables that are underlined with asterisks in the data files header indicate they have a data-quality flag. Data-quality flags are defined as follows:

1 = sample for this measurement was drawn from water bottle but analysis was not received

2 = acceptable measurement

3 = questionable measurement

4 = bad measurement

5 = not reported

6 = mean of replicate measurements

9 = sample not drawn for this measurement from this bottle
