Background

Georgia is among the countries which have fresh groundwater distinguished for significant resources and naturally high drinking quality. This is evidenced by years of hydrogeological exploration works and monitoring researches conducted in the country to identify, assess, and protect fresh groundwater. Considering the intensive technogenic load on the environment, the assessment and protection of fresh groundwater resources have become a pressing issue for the government. After a hiatus, Georgia has started to take significant efforts from 2013 to restore the national network for fresh groundwater monitoring. Enhancing the groundwater monitoring network and improving the relevant data processing are the obligations set by the EU-Georgia Association Agreement (Title VI, chapter 3, article 306; article 306, annex XXVI “Water quality and resource management including marine environment” - https://eur-lex.europa.eu/legal-content/en/TXT/PDF/?uri=CELEX:22014A0830(02)), as well as being linked to the targets of the Sustainable Development Goal 6 on the management of water resources and sanitation.

LEPL National Environmental Agency (NEA), with support of donor organisation, has installed modern hydrogeological monitoring equipment on the existing wells. These measures have been followed by the gradual connection of water points to the central monitoring network, and currently, it covers 56 water points countrywide – 50 wells and six natural springs. Twice a year (in June and December), NEA performs chemical and bacterial laboratory analysis of groundwater. However, the hydrogeological monitoring network enlarges every year and the database on quantitative and qualitative characteristics of fresh groundwater is being expanded based on the information received from water points, fieldwork results, laboratory analyses (chemical and bacteriological), and on the processing and generalising of the collected actual materials. Concurrently, the monitoring network's improvement, the amount of statistical information (geological, stratigraphic, hydraulic, hydrodynamic, qualitative, technical and other hydrogeology data) to be processed is also increasing, which is a severe challenge to NEA. Specifically, it is necessary to produce groundwater databases and modelling using a specific computer program for a groundwater modelling system that will support the efficient management of fresh groundwater resources, elaborating relevant water policies and implementing modern water management methodologies in Georgia. Moreover, the introduction of a groundwater monitoring system and its methodology should be in full compliance with the EU Water Framework Directive (WFD https://eur-lex.europa.eu/resource.html?uri=cellar:5c835afb-2ec6-4577-bdf8-756d3d694eeb.0004.02/DOC_1&format=PDF) and the principles of integrated water resources management.  

Selection and introduction of the above-mentioned modelling system is a challenging task for NEA since the responsible department lacks the relevant expertise and knowledge of the specificity of different programmes because of the necessary data and characteristics. Accordingly, MEPA has requested UNDP to provide support and technical assistance through an international consultant to introduce the methodology of groundwater modelling system, recommend the most applicable programme due to the existing circumstances, and strengthen the Agency’s staff capacity in applying for the modelling programme. This will enable NEA to rapidly process, visualise and analyse the research results, which lead to efficient policy development.

 

Duties and Responsibilities

The overall objective of the consultancy is to provide support to NEA in introducing a methodology of groundwater modelling system, recommend the specific modelling programme for further develop digital monitoring abilities and data processing mechanisms and familiarize the Agency staff with practical training about the groundwater modelling system specifications. The international consultant should review the existing groundwater monitoring practices and types of available data and present the deliverables in full compliance with the WFD, the EU standards and modern methods.

The scope of work for the international consultant will include, but may not be limited to:
