The linkage between precipitation and recharge is still poorly understood in the Central America region. This study focuses on stable isotopic composition groundwater northern mountainous region of Valley Costa Rica. During dry season, rainfall samples corresponded to enriched events with high deuterium excess. By mid-May, Intertropical Convergence Zone poses over Rica resulting a depletion 18O/16O 2H/H ratios. A parsimonious four-variable regression model (r2 = 0.52) was able predict daily...
The objective of this research was to determine the level knowledge and perception Costa Rican population about water for human consumption, general concepts, impact activities, occurrence extreme events management governance. In 2016, a quantitative-descriptive study carried out through semi-structured survey in which 800 people were consulted, calls landlines. It found that Ricans: a) perceived is public good there greater availability than reality, b) 22 % indicated having supply...
Nitrate pollution threatens the Barva and Colima multi-aquifer system, primary drinking water source in Greater Metropolitan Area of Costa Rica. In addressing nitrate contamination dynamics, this study proposes an integrated approach by combining multivariate statistical analyses, hydrochemical parameters, sewage discharge, regional land-use land-cover patterns to assess extent degree contamination, dominant biogeochemical processes, refine interpretation sources previously derived solely from δ
Abstract The volcanic Barva and Colima multiaquifer system is crucial for the drinking water supply of about 1.7 million people, 30% population in Costa Rica. complexity this simultaneous occurrence anthropogenic natural processes complicate understanding hydrochemical hydrogeological dynamics, both essential groundwater protection. This research aimed to develop a model discrimination groundwaters according main withdrawn aquifer flow path, assess interaquifer connections, evaluate...
El agua de los acuíferos Barva, Colima Superior y Inferior, ubicados en el sector oeste del Valle Central Costa Rica, representa la principal fuente abastecimiento potable esta región. propósito este estudio fue diseñar una red monitoreo o vigilancia para calidad estos las subcuencas ríos Bermúdez, Ciruelas río Segundo, así como fomentar participación actores sociales funcionamiento cada vigilancia. De sitios propuestos, cinco sobrepasaron, dos a cuatro ocasiones, Valor Alerta 25 mg/l...

Tecnología Ciencias del Agua, 8(1), 115-132.La composición química agua subterránea está determinada por procesos antropogénicos interacciones con material geológico que conforma acuífero. El presente estudio describe la caracterización Colima, Rica, fin ampliar conocimiento acerca las entre ambos...
Las subcuencas del río Maravilla-Chiz y Quebrada Honda, localizadas en la región oriental área metropolitana de Costa Rica, tienen una superficie aproximada 46,8 km2, donde principal actividad económica es producción tanto agrícola como pecuaria su población se abastece fuentes agua subterránea. El objetivo investigación fue determinar amenaza contaminación subterránea, mediante evaluación estado las áreas protección manantiales abastecimiento público. Para eso, tomaron cuenta potenciales...
En las últimas dos décadas, el Pacífico Central de Costa Rica experimentó un fuerte aumento en desarrollo urbanístico y turístico, lo que representa una mayor amenaza a la calidad del agua subterránea. El objetivo este estudio fue generar propuesta Mapa Vulnerabilidad Hidrogeológica los acuíferos Jacó, utilizando metodología GOD. Para esto, se elaboraron perfiles geológicos realizó comprobación campo. Se evidencia área está conformada por a) acuífero costero detrítico, poroso libre,...
In the eastern region of central Costa Rica, land use in sub-basins Maravilla-Chiz and Quebrada Honda rivers (47 km2) is dominated by agricultural livestock production, while groundwater resources constitute main drinking water supply. This study aimed to (a) evaluate location recharge areas flow paths, (b) provide a characterization hydrochemistry possible anthropic impacts. Groundwater was collected from 20 sites during dry rainy seasons analysed for major ions, stable isotopes 222Rn....
Rapidly urbanizing coastal communities are prone to overpopulation and unrestrained growth that result in pathogen nutrient emissions, which impair beach water quality jeopardize human environmental health. Decision makers face complex, context-dependent choices when selecting sanitation technologies with varying abilities remove pathogens nutrients. The goal of this study was identify context-appropriate solutions manage nutrients ensure safe swimming conditions an town relies on tourism....
In the last two decades, Central Pacific of Costa Rica experienced a strong growth in urban and tourism development. If not regulated, this development can result pressure to groundwater resources and, therefore, threat terms quality quantity. study, hydrogeological vulnerability map Jacó aquifers was performed, by GOD method. Geological profiles were elaborated, field verification performed. It is confirmed that, study area, are found: a) detritic, porous, unconfined coastal aquifer,...
[Introduction]: In Costa Rica, more than 70 % of the public drinking water supply comes from groundwater sources. coastal city Jacó, on Central Pacific Coast tourism activity is essential for economic development and represents a source supplying tourists residents. [Objective]: This research aims to characterize threats contamination aquifer Jacó due human activities, based land use analysis, characterization potential pollution sources and, estimation floating population related tourist...
<p>The volcanic aquifers in the Valle Central, most urbanized region of Costa Rica, are essential providing drinking water to about 1.7 million people. Nonetheless, underlying hydrogeochemical processes governing physical and chemical groundwater quality have been rarely studied. The main objective this study was evaluate natural controlling urban Barva Colima aquifers, by using multivariate statistical analyses hydrochemical tools. A total 571 samples collected quaterly, from...
