Foster, StephenHirata, RicardoGomes, DanielD'Elia, MonicaParis, Marta2013-06-112013-06-112002-09-300-8213-4951-1https://hdl.handle.net/10986/13843This publication provides guidance to water-sector decision makers and planners on how to deal with the quality dimension of groundwater resources management in the World Bank's client countries. There is growing evidence of increasing pollution threats to groundwater and some well-documented cases of irreversible damage to important aquifers. This guide has been produced in the belief that groundwater pollution hazard assessment must become an essential part of environmental best practice for water supply utilities. The guide is particularly relevant for the World Bank's Latin American and Caribbean Region, where many countries have initiated major changes to modernize their institutional and legal framework for water resources management, but may not yet have considered groundwater at the same level as surface water, because of lack of awareness and knowledge of groundwater issues and policy options.en-USCC BY 3.0 IGOABSTRACTION RATEABSTRACTIONSADSORPTIONAGRICULTURAL CULTIVATIONAGRICULTURAL IRRIGATIONANIMALSAQUATIC ECOSYSTEMSAQUIFERAQUIFER BOUNDARIESAQUIFER POLLUTIONAQUIFER POLLUTION VULNERABILITYAQUIFER PROTECTIONAQUIFER RECHARGEAQUIFER SYSTEMAQUIFER SYSTEMSAQUIFER VULNERABILITY MAPPINGAQUIFERSARSENICATTENUATIONBACTERIABOREHOLESBUFFER ZONESCATCHMENTCLEAN-UPCOALCODCONSERVING WATERCONSTRUCTIONCONTAMINANT TRANSPORTCOOLINGCOVERINGDEEP AQUIFERSDISINFECTIONDOMESTIC WASTEWATERDRAINAGEEFFLUENT DISCHARGEENVIRONMENTAL SUSTAINABILITYEXCESSIVE ABSTRACTIONEXCRETAFAULTSFEFRESHWATERGASGEOLOGICAL FORMATIONSGLOBAL WATER PARTNERSHIPGRAVITYGROUNDWATERGROUNDWATER ABSTRACTIONGROUNDWATER EXTRACTIONGROUNDWATER MANAGEMENTGROUNDWATER POLLUTIONGROUNDWATER PROTECTIONGROUNDWATER QUALITYGROUNDWATER QUALITY DETERIORATIONGROUNDWATER RECHARGEGROUNDWATER RESOURCEGROUNDWATER RESOURCESGROUNDWATER SOURCESGROUNDWATER STORAGEGROUNDWATER SUPPLIESGROUNDWATER SUPPLYGROUNDWATER TABLEGROUNDWATER USERSHEAVY METALSHYDRAULIC CONDUCTIVITYHYDRAULIC PROPERTIESHYDROCARBONSHYDROGEOLOGYINDUSTRIAL PREMISESINDUSTRIAL SOLID WASTEINDUSTRIAL WASTEINFILTRATIONINFILTRATION GALLERIESIRONIRRIGATION FIELDISOTOPESLAND SURFACELAND USELANDFILL LEACHATELATRINESLEAKAGEMANGANESEMINERAL WATERSMINERALSMININGMOISTURE CONTENTMONITORING PROGRAMMUNICIPAL WASTEWATERMUNICIPAL WATERMUNICIPAL WATER SUPPLIESMUNICIPAL WATER SUPPLYNATURAL RECHARGENITRIFICATIONNUTRIENTSORGANIC COMPOUNDSORGANIC MATTERPATHOGENSPERCOLATIONPESTICIDESPIPEPOLICY LEVELPOLLUTIONPOLLUTION CONTROLPOROSITYPOTABLE WATERPRECIPITATIONPRESSUREPROTECTION AREASPROTECTION OF GROUNDWATERPROTECTION OF GROUNDWATER RESOURCESPUBLIC HEALTHPUBLIC WATER SUPPLYPUMPINGPUMPING RATESPUMPING WELLSQUALITY OF WATERRAINFALLRAW WATERRUNOFFSAFE DISPOSALSANITARY ENGINEERINGSANITARY SURVEYSSANITATIONSEDIMENTSSEPTIC TANKSSEWAGESOIL MEDIASOIL PROFILESOILSSOLID WASTESOLID WASTE DISPOSALSOURCE PROTECTIONSPRINGSSTORAGE TANKSSUBSURFACE WATERSULPHATESURFACE WATERSURFACE WATER BODIESUNDERGROUND STORAGEUTILITY COMPANIESVADOSE ZONEVIRUSESWASTEWATERWASTEWATER DISPOSALWASTEWATER IRRIGATIONWASTEWATER REUSEWATER AUTHORITYWATER BALANCEWATER BODYWATER COMPANIESWATER DEMANDWATER DISTRIBUTIONWATER DISTRIBUTION NETWORKSWATER POLLUTANTSWATER QUALITYWATER RESOURCEWATER RESOURCES MANAGEMENTWATER SERVICEWATER SUPPLYWATER SUPPLY UTILITIESWATER SYSTEMSWATER TREATMENTWATER UTILITIESWELL DRILLINGWELL MAINTENANCEWorld Bank10.1596/0-8213-4951-1
