GUISBERT H, Elvira et al. NITROGEN POLLUTION ON GROUNDWATER RESOURCES OF BELEN PITUTA B, GUAQUI TOWN-BOLIVIA. Rev. Bol. Quim [online]. 2007, vol.24, n.1, pp.85-89. ISSN 0250-5460.

ABSTRACT 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
