The main goal of this study is to analyze nutrient and chemical loads in groundwater and streams in Pampa region, Argentina. For studying groundwater loads, a set of 19 observation wells were installed in 2011, in western Buenos Aires. The wells were located at three landscape positions (upper, middle and lower hill) in seven agricultural fields and groundwater samples were monthly collected. As for surface water, two watersheds located in southeastern Buenos Aires, were chosen: Napaleofú creek Watershed (34.000 hectares) and Quequén Grande River watershed (938.000 hectares). Daily water samples were taken from the main stream from October 2011 to November 2013, at both watersheds. Water Samples collected from wells and streams, were analyzed to determine N, and chemical loads. A group of 12 Herbicides and 3 insecticides frequently used by farmers in the watershed were chosen for the study. Nitrogen and chemical concentrations were analyzed considering rainfall events and also compared to critical limits. As for NO3-N concentration, most of wells presented variable concentration depending on monthly precipitation and landscape position.
