Hydrobiogeochemistry of Two Catchments in Brazil Under Forest Recovery in an Environmental Services Payment Program

“…Considering the results of Reis (2018) for the monitoring from January 2015 to January 2016 regarding the magnitudes of major ions, the differences of the present work conducted in 2017 is that Na + , K + , Mg 2+ , and Clconcentrations in 2017 have peaks that were not observed before. Therefore, it seems that the mentioned point sources of pollution became more frequent in 2017.…”

“…As this SC sampling station has more houses in the vicinity, such NH 4 + values can be a response to improper domestic sewage disposal, even though this very tiny urban neighborhood was not considered in the land use classification as commented regarding to PS (Table 1). Perhaps at SC this has more effect over the NH 4 + concentrations than the presence of the grass in the riparian zone as mentioned by Reis (2018) who related this land cover at PS to higher NH 4 + values. Thus, it was evident that there was a point pollution source, probably related to a small food industry and/or a small fish farm present at the lower reach of the PS stream, as well as signals of bovine urine and feces regarding to cattle visits to this stream.…”
