Data Qualifiers and Definitions
ND Analyte NOT DETECTED at or above the reporting limit
NR Not reported
RPD Relative Percent Difference
J The reported J value is between the laboratory's MRL and MDL. Constituents detected in this range, have a higher degree of
uncertainty and a lower level of precision. The J value was reported at the client's request or as a regulatory requirement.
S5 The raw sample concentration was greater than four times the spike concentration. The spike recovery was not evaluated against the
control limits.
Z Sample j -value is 0.004 mg/1. Duplicate j -value is 0.004 mg/l
Za Sample j -value is 0.039 mg/1. Duplicate j -value is 0.036 mg/1
