The assignment envisages the following activities with regard to the 93 Ground Water Bodies (GWBs)in Bulgaria identified in the River Basin Management Plans (2016-2021) as not being in good status (63) or to be at risk of not achieving good qualitative or good chemical status (30): the implementation of the updated methodologies/approaches and delineation of the groundwater bodies, updating the characterization of GWB,
determining the background level concentration (BGL) and threshold values (TV) for contaminants in the GWB, evaluating the pressures and risks for the quantitative and chemical status applicable to the GWBs and identifying the trends, and finally evaluating the quantitative and chemical status of the GWB.

The specific objective of this assignment is to support the elaboration of the next River Basin Management Plans with the implementation of a series of field works over the groundwater bodies not being in good quantitative or chemical status and the groundwater bodies at risk not being in good status. The said field work is aiming at: 1) estimating the number of boreholes tapping each groundwater body and estimating the average pumping yields per usage, both data being necessary for estimating the total pumped yield per groundwater body; and 2) providing a series of groundwater quality analysis be used as a first countrywide groundwater sampling which might be used, in complement with every existing groundwater quantity results, to support the implementation of a state of the art quality monitoring network.
