3.3. Pressures and impacts on groundwater
3.3.1. Introduction
Article 5 of the WFD requires Member States to identify the significant pressures present in the RBD likely to cause groundwater bodies to be of less than good status. It also requires Member States to assess the impacts on groundwater bodies to support the determination of status.
Class: GroundWaterBody
gwSignificantPressureType - Required.(SignificantPressureType_Enum)
Indicate the significant pressure type(s) from the enumeration list .
Similar comment to SWsignificantPressureType
The codelist of Annex 1a shouldn't be splitted by drivers as usually the relation pressure- driver is 1:n
Since the guidance says 'Significant pressures should only be reported for those water bodies which have been identified as being at risk'
we propose to extend the quality check (not only check consistency with status but with risk aswell)
Within-schema check: If (SWB/GroundWaterBody/gwChemicalStatusValue is ‘3’ or GWB/GroundWaterBody/gwChemicalStatusExpectedGoodIn2015=No), at least one significant pressure type must be selected from the enumeration list (can include ‘8 Unknown pressures’). The option ‘No significant pressure’ is not a valid selection.
and the same check for quantitative status/risk
List of pressure types and impact types should be announced in an early stage of the management cycle. Befor the analysis has been done. No midcycle change.

gwSignificantPressureOther - Conditional.
If ‘7 – Anthropogenic pressure - Other’ is selected from the enumeration list and reported under gwSignificantPressureType, provide details of any other anthropogenic pressures which are relevant in this element. This element should only be reported if the pressure type is not included in the enumeration list under gwSignificantPressureType.
gwSignificantImpactType - Required.(SignificantImpactType_Enum)
Indicate the impact type(s) from the enumeration list.
Since the guidance says 'Therefore, a pressure or impact should only be reported if it is significant, alone or in combination with others, because it puts the Environmental Objectives at risk
we propose to extend the quality check (not only check consistency with status but with risk aswell)
Within-schema check: If (GWB/GroundWaterBody/gwChemicalStatusValue is ‘3’ or GWB/GroundWaterBody/gwChemicalStatusExpectedGoodIn2015=No), at least one significant impact type or the option ‘UNKN - Unknown impact type’ must be selected from the enumeration list. The option ‘NOSI - No significant impact’ is not a valid selection.
and the same check for quantitative status (risk/status)
The table in Annex 1b needs revision. There is a mix of impacts for surface waters and groundwaters that originates from different objectives in the directives. In general, some of the impacts directed towards surface waters may also be relevant for groundwaters, eg acidification, but is not a focus area in the directive. This table should either 1) be split into two (sw/gw), 2) revised accordning to actual possible impacts for the two water types, or 3) a reference to eg directive articles should be given for all impact types.

gwSignificantImpactOther - Conditional.
If ’ OTHE - Other significant impact type’ is selected from the enumeration list under gwSignificantImpactType, provide details of any other impact types which are relevant in this element. This element should only be reported if the impact type is not included in the enumeration list under gwSignificantImpactType.
