HNO3 EXTRACTABLE ELEMENTS TO BE DETERMINED FROM GROUNDWATER AND
SURFACE WATER SAMPLES
The following requirements are defined for groundwater and surface water samples (preserved water
samples). Total content of elements will be determined from water samples after addition of concentrated
HNO3 and heating at 90 oC. Table provides the list of elements detection limits that should be reached.
Minimum list of elements to be determined with detection limits, desired practical detection limits and fields
to be filled in. Minimum criteria: at least 90 % of the concentrations of all the listed elements will be
determined with detection limit (or better). If the desired DL is defined, additional points will be given for
elements determined with the desired practical detection limit.
