“…Concentrations of cations and anions in groundwater reported by Cardona and Hernández (1995), Edmunds et al (2002) and Huizar-Alvarez et al (2004) show a significant increase for water sampled in the plain of Texcoco-Ixtapalapa (Tables 2, 3, 4), away from the recharge zone of the Sierras.…”

“…Towards the plain, Cl -content increases from &20, 30 to 90 mg/L in the centre of the plain, and C150 mg/L in Ixtapalapa, Texcoco, and Tlá-huac. In some cases, the source of Cl -is attributed to anthropogenic origin, mainly for boreholes close to sewage canals (Huizar-Alvarez et al 2004). Tables 3 and 4 belong to the same geographical space, but the location of some boreholes is in different lithological unit; mostly, data correspond to different boreholes and sampling time Another characteristic of the CMZM groundwater is the increase in Na/Cl ratio in relation to Mg 2?…”

“…The accessible groundwater chemical information in the CMZM (Cardona and Hernández 1995;SMA 1999;DGCOH 2000;Edmunds et al 2002;Huizar-Alvarez et al 2004) indicates increasing values of electrical conductivity, temperature, and the concentrations of some trace elements as Li from the recharge zone to the centre of the plain (Tables 2, 3, 4). On the edges of the plain, water salinity is low but increases gradually towards the thermal water discharge zone of Peñón de los Baños.…”

“…The hydraulic data properties of units 4 and 5 are usually assessed and reported for production boreholes (DDF 1984;Vázquez-Sánchez 1995;Vargas-Cabrera 1995;Huizar-Alvarez et al 2004). However, the hydraulic conductivity (K) and storage coefficient (S) of units 1, 2, and 3 are unknown within the studied region as drilled boreholes never reach depths where these units subcrop.…”

Groundwater flow systems have been differentiated in the metropolitan zone of Mexico City based on their chemical composition and stable isotope contents. The existing hydrogeological framework for the region provided a reference for such differentiation. Local flows (Flow-system I) represent the youngest and shallowest groundwater flow identified in boreholes on the hills. Intermediate flows (Flow-system II) in boreholes on the plain represent a mixture of inflows travelling horizontally, and vertically upwards (Flow-system IV) and downwards (overlaying aquitard leakage) to extraction boreholes. Flow-system III identified in boreholes on the plain is an intermediate flow system which extends deeper than Flowsystem II. Flow-system IV, which is classified as a regional system, is related to a former thermal spring site. Groundwater travelling times, and their regional distribution and the thickness of related rock formations suggest extensive inflow supporting Flow-system IV. Future climate condition evolution (i.e. drought) will only have a limited impact on Flow-system IV as compared to Flowsystem I which have relatively rapid and short flow paths.The identification of the hierarchy of the flow systems is of paramount importance in achieving adequate groundwater management in any region where the aquifer units are several thousand metres thick.

“…The watertable is now more than 70 m depth, just some meters below the base of the aquitard, so confined conditions have changed to unconfined (there is an unsaturated zone below the base of the aquitard causing low hydraulic conductivity conditions) Intensive and deep soil cracking has been commonly reported since the 1970s. An application of the understanding of groundwater flow systems may imply that groundwater functioning from where the movement of water might be traced and the processes defined, as to deduce a possibility of natural control as for instance the rate of subsidence has been reduced by the disconnection of the hydraulic movement of water from the aquitard to the aquifer unit beneath (Huizar-Alvarez et al, 2004).…”

Problem statement: The interest in early hydrogeological studies was the aquifer unit, as it is the physical media that stores and permits groundwater transfers from the recharge zone to the discharge zone, making groundwater available to boreholes for water extraction. Approach: Recently, the aquifer concept has been complemented by the groundwater flow system theory, where groundwater may be defined by local, intermediate and regional flow systems. This implies that groundwater may travel from one aquifer unit to another aquifer unit (or more) located above or below the former. Water in a local flow system takes months or several years to travel from the recharge to the discharge zone. These flows usually transfer the best natural quality water, so a reduction in precipitation would lessen recharge and diminish stored water, making them more vulnerable to contamination and variability in climatic conditions. Thus, there is a need to define local flows and to enhance actions to protect them from contamination and inefficient extraction. Results: In contrast to local flows, intermediate and regional flows travel from a region, or country, into another, with their recharge processes usually taking place in a zone located far away from the discharge zone (natural or by boreholes). There is a need of groundwater flow systems evaluation by means of an integrated wide system-view analysis of partial evidence represented by surface (soil and vegetation covers) as well as hydraulic, isotopic and chemical groundwater characterization in the related geological media where the depth of actual basement rock is paramount as well as discharge areas. The flow system definition may assist in extraction management strategies to control related issues as subsidence, obtained the water quality change, desiccation of springs and water bodies, soil erosion, flooding response, contamination processes in recharge areas, among others; many of which could be efficiently managed leaning on groundwater functioning. There is increasing evidence that climate becoming more variable and key driver of ecosystem health. Even with climate stability, most developing countries will confront serious water problems by the mid-21st century due to an insufficient knowledge of the functioning of their groundwater sources representing ≈ 99% of available water. Conclusion: Many such problems may be adequately controlled when local flows are defined, since changes in climatic condition are more prone to affect local flows rather than intermediate and regional flows. The value of the flow systems arises from the fact that a wide system view analysis allows adequate crossed examination among relevant data from where water management proposals might more adequately represent field conditions. Examples of successful application of the groundwater flow systems in Mexico and Argentina will be presented including: induced fluoride control, subsidence response, desiccation of springs, flooding water origin definition, basement position in flow-system c...
