STORET Result Remark
Note: EPA no longer updates this information, but it may be useful as a reference or resource.
This web site provides query access to over 200 million monitoring records originally reported to EPA via the Legacy STORET System.
Code | Description |
---|---|
A | Value reported is the mean of two or more determinations. |
B | Results based upon colony counts outside the acceptable range. |
C | Calculated. Value stored was not measured directly, but was calculated from other data available. |
D | Field measurement. Some parameter codes (e.g., 401 "Field pH") imply this condition without this remark. |
E | Extra sample taken in composting process. |
F | In the case of species, F indicates Female sex. |
G | Value reported is the maximum of two or more determinations. |
H | Value based on field kit determination;results may not be accurate. |
I | The value reported is less than the practical quantification limit and greater than or equal to the method detection limit. |
J | Estimated. Value shown is not a result of analytical measurement. |
K | Off-scale low. Actual value not known, but known to be less than value shown. |
L | Off-scale high. Actual value not known, but known to be greater than value shown. |
M | Presence of material verified, but not quantified. Indicates a positive detection, at a level too low to permit accurate quantification. In the case of temperature or oxygen reduction potential, M =a negative value. In the case of species, M=male sex. |
N | Presumptive evidence of presence of material. |
O | Sampled for, but analysis lost. Accompanying value is not meaningful for analysis. |
P | Too numerous to count. |
Q | Sample held beyond normal holding time. |
R | Significant rain in the past 48 hours. |
S | Laboratory test. |
T | Value reported is less than the criteria of detection. |
U | Material was analyzed for, but not detected. Value stored is the limit of detection for the process in use. In the case of species, Undetermined sex. |
V | Indicates the analyte was detected in both the sample and associated method blank. |
W | Value observed is less than the lowest value reportable under remark "T." |
X | Value is quasi vertically-integrated sample. |
Y | Laboratory analysis from unpreserved sample. Data may not be accurate. |
Z | Too many colonies were present to count (TNTC), the numeric value represents the filtration volume. |
$ | Calculated by retrieval software. Numerical value was neither measured nor reported to the database, but was calculated from other data available during generation of the retrieval report. |
