eC2: Update delineation and characterization of the groundwater bodies at risk, including pressure and risks, and perform status assessment

Deadline: 07-Oct-2019 at 11:59:59 PM (Eastern Time – Washington D.C.)


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.
