| Study Result Description | In January 2020 data from 4 Spokane Studies in EIM (AJOH0005, SPOK9394, DBAT0001 and SPOKNR94) were combined into one Study in EIM (AJOH0005) because they contained duplicate data for some samples.
Sediment results in AJOH0005 were loaded to the 6 general fish sampling locations. Those same sediment results were also in EIM in Study SPOK9394 associated to more accurate sediment sampling locations. The sediment data in SPOK9394 lacked grain size results and the units were ppm/ppb. The sediment results are now under Study ID AJOH0005, associated with the more accurate sediment sampling locations, including grain size and units of mg/Kg or ug/Kg.
DBAT0001 and SPOKNR94 contained data for 3 Sample IDs (94328001, 94328002 and 94328003). AJOH0005/SPOK9394 also contained a few results for those same Sample IDs. The bulk of the data for Sample IDs 94328001, 94328002 and 94328003 was in DBAT0001 or SPOKNR94 but results for 3 aroclors, TOC, and grain size was in AJOH0005/SPOK9394. SPOKNR94 had additional data not in DBAT0001 for metals, semivolatiles and bioassay for those Sample IDs. All data for those 3 Sample IDs was combined into AJOH0005.
Study ID alias’s were added for all assimilated Studies and Location ID alias’s were added for combined duplicate Location IDs. |
