Resumen:
Water supply security is a top priority for decision-makers in cities.
Urban population growth increases water demand from aquifers, while
urban expansion reduces water infiltration and boosts water pollution
sources. Urban green spaces are a few of the remaining infiltration
areas. Therefore, they are essential for water supply and urban hydric
resilience. The urban dynamic directly influences shallow aquifers, but
they usually are unappreciated. This work illustrates the relationship
between urban green spaces and city water quality by evaluating the
influence of urban green space, Reserva Ecologica del Pedregal de San
Angel (REPSA), on a shallow aquifer in Mexico City. Five springs were
sampled: two upstream of REPSA, a spring within REPSA, and two
downstream. Because the study area is mainly residential but with an
industrial history, water quality was tested based on microbiological
pathogens, nutrients, pharmaceutical drugs, and heavy metals. Results
showed an enhancement of water quality of the shallow aquifer in the
sampling points downstream of REPSA for some of the pollutants. These
results illustrate how urban green spaces can help to dilute pollutants
present in the water of shallow aquifers, increasing water quality in
cities.
