    In the recent and ongoing review of the implementation of the directives by the European commission there seem to be concerns about grouping of groundwater bodies. Statistics in the reports on eg monitoring coverage do not consider grouping. At the same time grouping is explained to be the key for increasing monitoring coverage in the case when MS have a very large number of GWBs due to the natural hydrogeological conditions. Grouping must therefore be reported and presented in a different manner.


    The cause of confusion about grouping is probably due to unclear reporting schemas. In the first management cycle reporting of grouping was much more straight forward, where each GWB were related to a group identification number. This coming cycle it is necessary that this reporting is re-introduced with a possibility to have different groups for chemical and quantitative purposes, i.e. each GWB could relate to different group identifiers.

    Comments which should apply to all the schema elements in this Class: 
    There is no real connection between GML and XML schemas thus some information should duplicate, some are missing as basic information from XML. We would prefer if  all data in GML would be  included in XML as a view from GML schema element.

    In addition to those general schema element level comments:
    This XML should be linked with other GML GWB schemas and add a new element whether the water body has really changed or not, because in GML all changes will be registered without knowledge on reality (some very small changes because of the base map corrections either transformations between coordinate systems or joint point negotiations at country borders, etc.)
    This ensures that there is no conflict between the two types of data service (GML, XML).
