FlagDescription
I1Invalid value - known reason
M1Missing value because no value is available
M2Missing value because invalidated by data originator
M3Missing value due to clogged filter
NANot available from source data
V0Valid value
V1Valid value but comprised wholly or partially of below detection limit data
V2Valid estimated value
V4Valid value despite failing to meet some QC or statistical criteria
V5Valid value but qualified because of possible contamination
V6Valid value but qualified due to non-standard sampling conditions

qrcode

Quality rating code; A code indicating the relative quality of the sample; Possible values are:

FlagDescription
ASamples of the highest quality did not contain anything but water, all protocols were followed, and there is no indication of compromised integrity of the sample.
BSamples of unknown quality may contain contaminants such as plant matter or insects, or are potentially contaminated due to handling errors.
CSamples of the lowest quality are either of undefined duration, contain bird droppings, or have some other indication of compromised quality

labtype

Lab Type; A code indicating the condition of the sample upon arrival at the CAL; The possible values are:

FlagDescription
WSample volume of 35 mL or more
WISample volume of 10 - 35 mL; chemical measurements are made as volume permits in the following order: pH, Conductance, {NH4, PO4}, {Cl, NO3, SO4}, and {Ca, Mg, Na, K}.
DSample volume of 0 - 10 mL. Sample was not shipped.

sp

Sample protocol code. A code indicating departures from standard sample collection procedures that may have compromised sample integrity; The possible values are:

FlagDescription
(blank)No identifiable departures
UUndefined sample type
QQuality assurance sample

sl

Sample level code. A code indicating departures from field or laboratory standard operating procedures; The possible values are:

FlagDescription
(blank)No identifiable departures
CContaminated sample
ELong-duration sample
FField error
LLaboratory error
MMissing sampling information
