167 Sample quantity
In the DEM and DEO forms, the submission of with no analysis (e.g. no precipitation, no analytical results) should be distinguished from periods with missing data:
For periods without precipitation, the start and end date has to be filled in and the column “sample quantity” has to be filled in with “0”, leaving all the other columns blank and in the column “Other observations” the following remark has to be made “no precipitation”.
For periods with missing data (e.g. lost samples), the start and end date has to be filled in and the precipitation quantity has to be indicated (if available) and in the column “Other observations” the following remark has to be made “sample lost”.
In case that no quantity value is availabe for a specific period the field should be left empty and a V_sampling code "3" or "4" should be given .
Don’t use “0” as quantity as this could be interpreted as “no precipitation” in this period.
