The pollution of surface and groundwater by using fertilizers at agriculture areas of baskil (Elaziğ) and its close vicinity

This thesis were investigated the pollution of surface and groundwater by using fertilizers at agriculture areas of Baskil and its close vicinity.In the studied area from bottom to top Permo-Trias Keban Metamorphites, Coniasian- Santonian upper Baskil Magmaties, Lower Paleocene Kuşcular Formation, Tanesien-Lower Paleocene Seske Formation, Lutetion-Upper Oligosen Kırkgeçit Formation and Pliecene-Quaternary sandstone, clay, silt, limestone and debris are present.In the studied area, formations bearing groundwater are Keban Metamorphics, Baskil Magmaties, Seske Formation, Kırkgeçit Formation and Pliocene aged conglomerates, silt and sandstone.The permeability of Pliocene sediments are between 7,48.10-4 m/sn and 17,4.10-3 m/sn, porosity is between 30 % and 40 %.In the studied are borehole and surface waters? temperatures and elecrical conductivity are range from 12,6 ºC to 21 º C, and from 161.5 to 574µS/cm. The abundant ions in waters are Ca+2 and HCO3-2.As results of chemical analysis of waters, a periodic increase was observed in K+ values. This increase causes that the value of K+ is observed much more in the arid seasons, but less in rainly seasons. Furthermore, increase in K+ ions used densely may be the result of using fertilizers containing K+.In the studied area waters, the NH4-N, NO2-N concentrations were examined periodically and increased concentrations were determined. According to NO3-N values in waters, pollutants from the surface was determined by the pollutant.While there is no a specific on NH4-N, NO2-N, NO3-N ve PO4-3-P concentration ratios of groundwater and surface water of fertilizers used in studied area, it occurs that there is a risk of pollution in waters in future periods because of the different values of fertilizers as a result of analysis of water samples taken in different periods.It is determined that groundwaters and surface waters in Baskil it?s and near surrounding are convenient for the Turkish Driking Water Standarts. However, the pollution happen in groundwater and surface water is caused by agricultural reasons in the future, will have been prevented by controlling both kinds and amounts of fertilizers used for water pollution.
