Natural and anthropogenic features influencing water quality in NE Buenos Aires, Argentina
9 páginas, 5 figuras, 5 tablas, 2 mapas.-- Trabajo presentado en el VI ALHSUD- XXXII AIH Congreso Mar del Plata 2002.This work study water quality of the Pergamino River watershed in the Undulated Pampa in the northeast of the Argentinean Province of Buenos Aires. Temperature, pH, specific conductivity, Na, K, Mg, Ca, SO42Cl; HCO3, NO3, Si, Ag, Al, As, B, Ba, br, Cd, Co, Cr, Cu, Fe, Hg, Li, Mn, Mo, Ni, P, Pb, Se, Tl, U, V, Zn, and the (omega 18) O and (omega2)H isotope ratios were monitored in eighteen sampling stations. Groundwater and surface water are of sodium bicarbonate type, evolving to sodium sulfate-chloride type in the case of surface water.This work has been partially funded through the Proyect T657 from University of Buenos Aires.Peer reviewe

Comparación hidroquímica en diferentes ambientes de la provincia de Buenos Aires
63. Galindo G., Marquez J. J., Sainato C .M., Fernández-Turiel J. L. Comparación hidroquímica en diferentes ambientes de la provincia de Buenos Aires. En: Calidad y Contaminación de Agua Subterránea. VII Congreso Argentino de Hidrogeología y V Seminario Hispano-Latinoamericano sobre Temas Actuales de la Hidrología Subterránea. Edita: Asociación Civil Grupo Argentino de la Asociación Internacional de Hidrogeólogos-AIH, Buenos Aires, Argentina, 2011. 1ª ed., pp. 329-336. E-book ISBN: 978-987-23936-7-0.[EN] A comparative study of shallow groundwater was carried out in three hydrogeological environments, the northeastern region of “Pampa Ondulada” (Rolling Pampa), the “Pampa Deprimida” at the Salado-Villamanca region and the Northwestern region (near Trenque Lauquen city) int the “Pampa Arenosa”. The three cases are analyzed in rural zones where water provision is through groundwater for both human consumption and agricultural activities that are developping there. The hydrochemistry of groundwater was related to subsoil lithology, geology, morphology and mineralogy to integrate the information and to understand the geological and hydrogeological framework where these values are manifested. Data from the three regions were compared: pH, conductivity, Ca2+, Mg2+, Na+, K+, Si, HCO3-, Cl-, SO42-, NO3-, Al, As, B, Br, Cu, Fe, Li, Ni Mn, P y Zn. At the Pampa Deprimida the greatest values were the following: pH, Cond, Na+, K+, Cl-, SO42, As, Br, Fe, Ni, Mg2+, Li, Al y P; at Trenque Lauquen: Ca2+, Mg2+, HCO3-, NO3-, and B; at the Pampa Ondulada: Si and Zn. The conclusion is that the hydrochemical characteristics of the three case studies are differentiated mainly by time of residence of water in the aquifer and local geomorphological characteristics.[ES] Se realizó un estudio comparativo de las aguas subterráneas someras, en tres ambientes hidrogeológicos, la región noreste en la pampa ondulada, en la pampa deprimida de la región del Salado-Villamanca y en la pampa arenosa, al noroeste en las inmediaciones de Trenque Lauquen. Dada las características hidrogeológicas distintivas en cada uno de estos ambientes, se investiga reforzar estas diferencias basadas en el conocimiento hidroquímico. Los tres casos se analizan en zonas rurales, donde el abastecimiento de agua es mediante agua subterránea tanto para el consumo humano como para las actividades agropecuarias que allí se desarrollan. Se relacionó la hidroquímica del agua con la litología del subsuelo, geología, morfología y mineralogía para integrar la información y poder comprender el marco geológico e hidrogeológico en el que se manifiestan estos valores. Se compararon los datos de las 3 regiones, de pH, conductividad, Ca2+, Mg2+, Na+, K+, Si, HCO3-, Cl-, SO42-, NO3-, Al, As, B, Br, Cu, Fe, Li, Ni Mn, P y Zn. Los mayores valores son los siguientes, en la Pampa Deprimida: pH, Cond, Na+, K, Cl-, SO42-, As, Br, Fe, Ni, Mg2+, Li, Al y P; en Trenque Lauquen: Ca2+, Mg2+, HCO3-, NO3-, y B; y en la Pampa Ondulada: Si y Zn. Las características hidroquímicas diferenciadas en cada uno de estos ambientes están influenciadas por el tiempo de residencia y por las condiciones geomorfológicas locales, las que se vincularon a elevado pH, Na+ y CO3H- dominantes.Este trabajo ha sido financiado parcialmente por el Proyecto ASH (Ref.

Surface and groundwater quality in the northeastern region of Buenos Aires Province, Argentina
10 páginas, 5 figuras, 4 tablas.This work studies the water quality of the Pergamino–Arrecifes River zone in the Rolling Pampa, northeast Buenos Aires Province, Argentina. Temperature, pH, specific conductivity, Na, K, Mg, Ca, SO4 2-, Cl-, HCo3-, NO3-, Si, Ag, Al, As, B, Ba, Be, Br, Cd, Co, Cr, Cu, Fe, Hg, Li, Mn, Mo, Ni, P, Pb, Se, Tl, U, V, Zn, and the environmental stable δ18O and δ2H isotope ratios were determined in 18 sampling stations. Natural and anthropogenic features influence surface and groundwater quality. Point pollution sources (septic wells and other domestic and farming effluents) increase the nitrate concentration. The values of pH, No3-, Al, As, B, Fe, and Mn exceed the respective Argentine reference thresholds in different sampling stations for human drinking water; B, Mo, U, and V for irrigation; and V and Zn for cattle consumption.This work was partially funded through Project PEI
