Research paper thumbnail of The role of groundwater in highly human-modified hydrosystems: a review of impacts and mitigation options in the Campo de Cartagena-Mar Menor coastal plain (SE Spain)

Environmental Reviews, 2016

Hydrological processes and water resources are increasingly modified by anthropogenic actions, le... more Hydrological processes and water resources are increasingly modified by anthropogenic actions, leading to multiple pressures on the environment and related ecosystems. A better understanding of the interactions between the anthroposphere and the hydrosphere is necessary to shape more sustainable societies. The pressure of human activities on the environment is especially high along the circum-Mediterranean area because of a combination of biophysical and economic factors. The Campo de Cartagena coastal plain, together with the Mar Menor lagoon, is one of the most exemplary areas in this aspect. This work analyzes this system at the basin level by providing a synthesis of the state of knowledge of each hydrological compartment and the links between them. We pay special attention to the important role that groundwater plays in the overall functioning of the system, both as a promoting and (or) mitigating agent. The principal identified impacts from human actions are water imbalance (2...

To evaluate if the soil and the aquifer underneath are affected by use of this type of water, samples have been taken over a period of several months from the wastewater treatment plant, the stabilization lagoon, and soil profiles. Analyses have been performed for total coliforms and aerobic bacteria, soil water pressure and soil water content, as well as chemical analyses of the irrigation water and water of the vadose zone. Soil profiles taken several times during the study indicate the absence of coliforms, except for a short period during summer. In the vadose zone and the aquifer, a significant increase in salinity was detected 10 months after starting the application.

Research paper thumbnail of Groundwater salinisation processes in a coastal irrigated plain, Korba El Mida case study Cap Bon (Tunisia)

HAL (Le Centre pour la Communication Scientifique Directe), Sep 13, 2015

Since the 1960’s the coastal aquifer overlying the irrigated plain of Korba El Mida (East coast o... more Since the 1960’s the coastal aquifer overlying the irrigated plain of Korba El Mida (East coast of Cap-Bon) has been under intensive exploitation leading to groundwater degradation quality by seawater intrusion and irrigation return flow. Also, the main coastal sabkhas (wetlands) are no longer the natural outlets of the aquifer, due to a reversal of the hydraulic gradient jointly with groundwater depletion. Since 1962 geophysical surveys, use of environmental isotopes and tracers, and groundwater monitoring campaigns for sampling and level measurements of existing piezometers and surrounding wells, have been carried out in order to assess origins of salinity, extent and evolution along time. Values of Electric Conductivity may range between 0.3 and 10.6 dS/m in the surroundings of Korba and El Mida; most piezometers and some wells had essentially sodium-chloride facies but some wells present a calcium-sulfate facies. High nitrate concentrations (up to 300 mg/L), potassium and sulphate increase due to mineral fertilizers and manure application are observed in some areas of the aquifer, fact supported by the Cl-NO3 diagrams. The high heterogeneity of the salinity distribution, due to geological and hydrodynamic conditions, generates complex groundwater mixing of different origins: seawater intrusion, irrigation return flow, natural recharge besides the existing induced aquifer recharge in the area. The spatial variability of concentrations in the Korba-El Mida aquifer reveals the complexity of the groundwater contamination by salinization and anthropogenic activities.

Para ello se han realizado estudios geofisicos mediante tomografia de resistividad electrica. La exploracion geofisica ha permitido identificar y en cierta manera confirmar la existencia de fracturas de los sistemas N-70 y N-130, anteriormente descritas por otros autores, asi como la relacion existente entre los materiales detriticos (sedimentos cuaternarios y miocenos) y el substrato betico (esquistos, cuarcitas, marmoles, filitas, dolomias y calizas).
