【 摘 要 】

In this study, a comparison of two methods, the Selective UV Spectrophotometrical Method and Reduction with Hidrazine Method, for the determination of Nitrate ion in groundwater, was carried out. For this purpose, the results from all the drinking water collectings of the city of Olavarría, Argentina, were employed. Both methods present significant different means, but they don´t present significant differences in their variances.
