Water quality is in constant interaction with and changed according to time and place through
natural and anthropogenic factors. It is also known that land use has a significant impact on water
quality parameters. In this study, it was aimed to determine the effects of different land-use types
(Forest, range and riparian) on water quality and which land-use type supports the most suitable
drinking water for watersheds in the Başkonuş Plateau in Kahramanmaraş Province. The field studies
were carried out in May 2019, and 2 sampling points were selected from each of the land-use
types. Chemical properties (pH, EC) and some element concentrations (19 elements such as Al, As,
Cu, B, Zn, Fe, P, Cd, Ca, Co, Cr, Pb, Mg, Mn, Mo, Ni, K, Na, and S) were investigated by using an
ICP-OES. According to the results, the water obtained from forest areas is more suitable for drinking,
having drinking water quality standards with a high pH value (7.59), and the Sulfur concentration
of water obtained from range area (26.72 μg S /L) exceeded and did not comply with drinking
water quality standards. When the chemical characteristics of the Meydan Dam were examined
according to the regulated water quality standards declared in water pollution laws, it is clear that
the dam basin has a high water quality standard (Class I). Therefore, a larger dam that can be built
in this basin would be able to supply quality water that the Kahramanmaraş metropolitan municipality
needs. Consequently, before deciding on the construction of the dam for drinking water,
land-use maps would be created in the basins, and the selection of basins that have dense and
qualified forestland would provide quality water.
