Abstract
Se realizó una evaluación del grado decontaminación por nitrógeno en aguas subterráneas (prof.: 40 a 80m) en época seca y húmeda a través del análisis de NO2-, NO3-, NH4+, NT, N-inorg y Norg, encontrándose concentraciones altas de NH4+ disponible en aguas subterráneas, rango: 0,006mgL- 1 a 8,5 mgL-1 y una baja presencia de oxígeno disuelto en la mayoría de los pozos (= 0,8 mgL-1) frenando la oxidación de NH4+ a NO3
The evaluation of nitrogen pollution degree on groundwater was made from dry to wet season. NO2 -, NO3-, NH4+, NT, N-inorg y N-org were analyzed. The results show highs NH4+ oncentrations on groundwater (depth: 40 - 80m):0,006 mgL- 1 a 8,5 mgL-1 and lows concentrations of dissolve oxygen on the mostly wells (lowestvalue ˜ 0,8 mgL-1) being impossible an oxidation from NH4+ to NO3-. Only NH4+ it's overpermissible limit of the law 1333 R.M.A
