Comparative study of the impact of urbanization on water quality in Three Pampean streams in Central Buenos Aires, Argentina.

Water quality was evaluated in three Pampean streams in Buenos Aires, two urban streams (Del Azul and Langueyú streams) and one rural stream (De los Huesos stream), comparing how it is affected by urbanization within reaches of the same stream and between different urban streams, and compared to the...

Sumario:Water quality was evaluated in three Pampean streams in Buenos Aires, two urban streams (Del Azul and Langueyú streams) and one rural stream (De los Huesos stream), comparing how it is affected by urbanization within reaches of the same stream and between different urban streams, and compared to the rural stream. Through the analysis of physicochemical variables, guidance levels, the water quality index of the National Sanitation Foundation and the indicator 6.3.2 of the Sustainable Development Goals, it was determined that the two urban streams would be mostly impacted in their post-urban reaches, due to sewage discharges. A greater recovery was observed downstream of these discharges in the Del Azul than in the Langueyú stream; in the first case, the greater flow and lower population would allow for greater recovery. In the pre-urban sector of these basins, as in the De los Huesos stream (rural), high levels of nitrate and phosphorus were detected, which could be of natural origin, although possibly influenced by agriculture. This study contributes to know the conservation status of Pampean streams, the effect of urbanization and to detect signs of pollution.
