In current study, NH4+ cation and Al metal concentrations in summer period were determined by ultraviolet-visible (UV-VIS) spectrophotometric technique in the total 6 swimming pools found in the province of Canakkale (Turkey). Merck Kits equivalent to EPA, APHA, ISO and DIN standards were used in spectrometric analyses. The monthly quality parameter results in this study were evaluated according to various limit standard values of different countries. As a result, NH4+ cation and Al metal concentrations varied between 0.003 and 0.999 mg L-1 (0.073±0.139 mg L-1), 0 and 0.652 mg L-1 (0.141±0.068 mg L-1) respectively.
