|Hydrogeological studies and drilling water supply boreholes, primarily for communities not connected with main government water supply schemes|
The Department conducts hydrogeological studies and drilling of production boreholes for meeting the needs of communities for potable water.
|2015: In 2015 eighteen (18) boreholes have been drilled, seventeen (17) of which for water supply, summing up to a total of 3613 meters. Thirteen (13) boreholes have been pump tested. These boreholes have been drilled in order to address water supply issues in the communities of Galata, Gialia, Ag. Georgiou kafkallou, Tsakistra and Troodos.|
|2016: In 2016, twenty (20) water supply boreholes have been drilled, summing up to a total of 4871 meters. Fifteen (15) boreholes have been pump tested. These boreholes have been drilled in order to address water supply issues in the communities of Louvaras, Palaichori Morfou, Prastio Kellakiou, Orounta and for the Arkolakhania Water Supply Scheme.|
|2017: In 2017, fifteen (15) water supply boreholes have been drilled, summing up to a total of 3361 meters. Thirteen (13) boreholes have been pump tested. These boreholes have been drilled in order to address water supply issues in the communities of Fterikoudi, Platanistasa, Zoopigi, Dymes, Archimantrida and for the Arkolakhania Water Supply Scheme.|
|Managing and licensing the use of government boreholes.|
Under the Geological Survey Law (140(Ι) /2013), no government borehole shall be used prior to the full reimbursement of its drilling cost to the Department or without the issuing of the relevant license. The Department has the responsibility of managing all government boreholes. Within this framework, it issues license for the use of government boreholes, upon a relevant application addressed to the Director. Such an application can be submitted by organized groups or individuals. In 2017 eight (8) new licences have been issued and 53 renewed.
1. Application form for the use of government boreholes
2. Application form for the renewal of the licence for the use of government boreholes
|Groundwater status assesment studies|
The Department values highly the compilation of studies related to water resources. These are mostly of practical nature aiming in contributing in the management, development and protection of the water resources. They are mostly carried out in collaboration with other government departments as well as with universities and research institutes.
Current hydrogeological studies:
a) Compilation of a hydro-lithological map of Troodos.
b) Participation in the European research project CrITERIA for studying hexavalent chromium (Cr6) in the groundwater in the Mediterranean region. Link στο έρευνες και προγράμματα
c) Monitoring and assessing the qualitative and quantitative status of the groundwater systems within the framework of National and European legislation implementation. Link στο έρευνες και προγράμματα
d) Participation to the European research project Resource for the compilation of a single hydrogeological map of Europe. Link στο έρευνες και προγράμματα
e) Participation in the European research project Hover for the better understanding of the mechanisms affecting of groundwater quality in Europe. Link στο έρευνες και προγράμματα
|Monitoring and assesment of the water status under the directive 91/676/EEC for nitropollution, the directive 2006/118/EC for groundwater and contribution to the implementation of the water framework directive 2000/60/EC|
|Monitoring network under the directive 91/676/EEC for the protection of waters against nitropolution of agricultural origin |
The network comprises of 222 groundwater and 13 surface water, quality monitoring stations. Sampling frequency is twice a year for groundwater and monthly for surface waters. This network is under the European directive 91/676EEC, in relation to the protection of waters against nitropolution of agricultural origin, and it covers all major aquifers although it focuses on Nitrate Vulnerable Zones (NVZs); namely the areas of Kokkinochoria, Kiti-Pervolia, Pegia, Akrotiri, Polis Chrysochous, Oroundas and Pentashinos.
|Monitoring network under the directive 2006/118/ΕΚ for the protection of groundwater from pollution and deterioration|
The network comprises of 92 groundwater quality monitoring stations. Sampling frequency is twice a year and the analysis is performed both by the State Laboratory (for pesticides, trace elements and organic compounds) and the Geological Survey’s laboratory (for chlorine ions, sulphates, nitrates and nitrate, ammonium and electrical conductivity).
|Groundwater level monitoring|
The network comprises of 81 telemetric and five (5) grounwater level and temperature loggers which cover the major aquifers of Cyprus. Eighteen (18) of these stations are also utilized for the groundwater quantitative monitoring program under the water framework directive 2000/60/EC. The collected data are saved and ustilized in water balancing studies, groundwater artificial and natural recharge studies as well as in monitoring seawater intrusion in coastal aquifers.
|Precipitation quality monitoring network|
The Department maintains a precipitation quality monitoring network that comprices of twenty (20) stations. Samples are collected from each precipitation event (higher than 20 mm.). Monitoring parameters are chlorine ions, sulphates, electrical conductivity and pH.
