Abstract: Ground and surface water quality can be affected by three different
forms of pollution, which are chemical, biological and physical pollution.
These polluting factors can influence natural environment and human health.
Nitrates in soil and ground water generally moves relatively slow and there is
approximately 20 years lag time between the detection of the pollutant and the
pollution activity in ground water. For that reason, it is assumed that nitrate
concentration can continue to affect current polluting activities for several
decades. In this study, groundwater pollution originated from agricultural
activities were investigated in Gümüþhac;ýköy urban area.
The concentrations of nitrate (NO_3^-) in groundwater of
Gümüþhacýköy Plain range from 0–15.61 mg/l, nitrite
(NO_2^-) 0–0.007 mg/l and ammonium
(NH_4^+) 0–0.5 mg/l. However other chemical parameters
such as pH, EC, TH, Ca^{+2}, Mg^{+2},
Na^+, K^+, HCO_3^ -,
Cl^-, SO_4^{-2} and
F^- were measured.
