dc.description.abstract | High amounts of phosphorus (P) in rivers come mainly from two sources: fertilizers washed off from agricultural
and urban areas by runoff water (non-point sources) and urban and industrial development which are translated
in P discharges from wastewater treatment plants (WWTP). This work analyses the content of P in water for
nearly 40 years inquiring into the origin of the sources, based on the hypothesis of runoff generation from the
detection of river streamflow increases during the P contribution episode and the previous precipitation. For this
purpose, the Guadaira River, which is located in the South of Spain and has a drainage surface of 1524 km2
, was
selected. In this watershed agricultural land use converges with numerous human activities resulting in high
pressures on water quality. We found 40% of the P contribution episodes found seem to come from the runoff
generated after the heaviest rainfall events, which normally occur between November and May. The remaining
60% of the P contribution episodes were found to be linked to point sources, which become more relevant from
June to September, reaching the highest concentration values (6–17 mg/L). The results highlight that the target
phosphate concentration value of 0.34 mg PO4/L imposed by the national legislation for a good state following
the Water Framework Directive 2000/60/EC is exceeded by 96% of the measurements during the period from
1981 to 2022. On a monthly basis, PO4 loads showed a linear relationship with river streamflow (R2 = 0.94).
However, on field measurements scale, a potential relationship between both variables was found, which
changed according to the improvement in the wastewater treatment and facilities for 1982–1994, 1995–2017
and 2018–2022. In these three periods, different significant decreasing trends of the P content were found,
mainly marked by the setup of each individual WWTP. | es |
