Groundwater ecology

Ecological assessment of groundwater and groundwater dependent ecosystems

Sampling microinvertebratesGroundwater is one of the most important natural resources on Earth which is currently under an exponential increase risks due to contamination and overexploitation. Integration of knowledge resulted from groundwater ecology will significantly advance our understanding of subterranean ecosystems, in terms of improvement/maintenance of water quality, bioremediation of contaminated aquifers as well as enhancing the knowledge on groundwater habitats and biodiversity conservation. The Groundwater Ecology group of IMDEA Water is focused on applying the ecological criteria for an integrated assessment of groundwater ecosystems health, by using crustaceans as bioindicators. Our R & D activities aim to unravel the biodiversity of groundwater crustaceans and the ecological factors controlling the community’s structure and function from pristine and contaminated aquifers. Current projects in the group address questions related to the impacts of agricultural practices on aquifers quality and of biotic community resilience and resistance; assess the impact of artificial recharged aquifers on groundwater ecosystems biota and the evaluation of toxic effects of emerging contaminants on groundwater crustacean species.

Madrid Advanced Wastewater Treatment Network (REMTAVARES)

REMTAVARES

The project is the reference point in terms of advanced technologies in wastewater management to ensure sustainable development for the Community of Madrid. Within the project we aim to test the ecotoxicological effects of pharmaceutical compounds on surface and groundwater crustaceans. With this work we also aim to examine the sensitivity of copepods and ostracods crustaceans and their use as sentinel species for assessing the health of hyporheic and groundwater ecosystems condition. The project is financed by the Community of Madrid: S2013/MAE-2716, 2014-2018) Team: Dr. Sanda Iepure; Dr. Serena Molina Martínez; PhD Researcher Raquel García Pacheco; Research Assistant Andrea Castaño Sánchez.

Surface / groundwater interactions – a biological and ecohydrological approach

The hyporheic zone is the subsurface flow area beneath and adjacent to streams and rivers characterized by active vertical and lateral exchanges of nutrients and organic matter among surface and groundwater, in response to variations in discharge and bed topography and porosity. Current projects of the Groundwater Ecology group aims to: i) assess structure and dynamics of hyporheic communities from rivers and streams in the Mediterranean and Arctic regions; ii) investigate the role of the hyporheic zone as an intermediary transfer area of pollutants from the surface rivers to groundwater; and iii) delineate the lateral and vertical spatial extents of the hyporheic zone, characterize the streambed architecture and provide detailed spatial information on vertical and horizontal continuity of hyporheic zone. We combine the biological assessments of hyporheic invertebrate’s community’s structural patterns and ecological features with the non-invasive geophysical techniques obtained by electrical resistivity tomography (ERT). The results of the proposed researches aims to highlight the use of hyporheic communities as an alternative proxy to investigate the water quality and surface water/ground water exchanges; to understand the hyporheic structure and function and its relation to the associated alluvial aquifers; and to provide an early warning signal of subsurface ecosystems quality decline. Our researches propose to advance our understanding of the ecohydrological processes occurring at the surface/groundwater interface and will endorse the effective incorporation of the hyporheic zone in stream management plans. Both facets are essential for the development of sustainable integrated water management strategies at the river basin level.

Intelligent system to optimize the use of water in agriculture (SMART-HYDRO)

SMART-HYDROSMART-HYDRO aims to incorporate technological advances in sensors, multispectral images and telecommunications to control the quantity and quality of groundwater in agricultural landscape, in order to reduce energy costs, water losses and environmental impact. Within SMART-HYDRO we explore the aquifers ecosystems status affected by agricultural activities (i.e. irrigation, use of fertilizers and pesticides compounds) by analyzing the groundwater crustacean’s community’s structural patterns and the alterations of ecosystem services they provide related to groundwater quality. (Funding: Plan Nacional de I+D+i, RTC-2014-2367-5; 2014-2018).
