Within the scope of hydrogeological surveys carried out by the MoAF General Directorate of Sta-
te Hydraulic Works at the scale of groundwater basins, in addition to the implementation steps
of the “By-law on the Protection of Groundwater against Pollution and Degradation”, groun-
dwater supply-discharge relations, natural background levels caused by lithological formations,
current concentrations and increase/decrease trends of pollutants caused by anthropogenic
pressure factors in sources and wells, origin analysis of water and its relations with surface wa-
ter resources are revealed.
In addition, within the scope of surveillance monitoring, physicochemical parameters were me-
asured in situ and basic ions, heavy metals, pesticides and organic pollutant groups that pose a
risk were analyzed in water samples taken from the study areas. After the holistic evaluation of
the project outputs of the completed hydrogeological studies, operational monitoring studies
were started.

C.3. Sectoral Water Uses and Water Allocations

According to the Official Statistics Programme, “Water Withdrawal and Use Statistics” are pro-
duced by the Turkish Statistical Institute (TURKSTAT).
Within the scope of “Water Statistics”, TURKSTAT compiles data from manufacturing industry
workplaces employing 50 or more people, all active thermal power plants with an installed ca-
pacity of 100 MW or more, all OIZ Directorates with completed infrastructure, mining enterpri-
ses declaring production for the reference year to the General Directorate of Mining and Petro-
leum Affairs and all municipalities in Türkiye. Water statistics for villages are obtained from the
Ministry of Interior (General Directorate of Provincial Administration) and agricultural irrigation
data are obtained from DSI and these data on water are reported to international organizations
in a holistic manner.

According to 2022 reference period TURKSTAT data, the total amount of surface and groundwa-
ter supplied by municipalities and villages in Türkiye is 7.07 billion cubic metres and the total
amount of surface and groundwater supplied by manufacturing industry, thermal power plants
and mining enterprises excluding sea waters is 1.24 billion cubic metres.

(Calculated according to the data taken from the table ‘2.7. Comparison of Total Groundwater Allocation and the Amount
of Surface Water Used for Irrigation in Türkiye, 2000-2022’ available at https://www.dsi.gov.tr/Sayfa/Detay/1847) It is the
sum of sea water and fresh water.
