Abstract The interrelation between hydrochemistry and hydrodinamics was analyzed in the basin of El Divisorio stream. This was to gain undestanding in the magnitude, distribution of toxic ions (As, F) and behaviour in the discharge of main nutrients (P, N) contributing to the eutrofication of Paso de las Piedras Dam. During two years, 47 sites were sampled determining several parameters: geographical position for each sampling point, phreatic level depth, and As, F, PO4 and N-NO3 concentrations. Repeated measures, Fisher test, correlation and regression analysis were applied to all variables. Highly significant space and time differences (P<0.01) with… More >
