NBLs can be used as screening levels to define the good chemical status of groundwater bodies, as well as to fix the remediation target in polluted sites.The book "Natural Background Levels in Groundwater" brings together a set of case studies across Europe and worldwide where the assessments and identification of this boundary are performed with different methodologies. It provides an overview of the approaches and protocols applied and tested in different states for NBL assessment, ranging from well-known methods, such as component separation or cumulative probability plot methods, to new computer-aided protocols. The main objective of this book is to bring together and discuss different methodological approaches and tools to improve the assessment of groundwater NBLs. The overview, discussion and comparison of different approaches and case histories for NBL calculation can be useful for scientists, water managers and practitioners.Environmental economicsbicsscPollution controlbicsscResearch & information: generalbicsscambient background valuesanthropogenic pressurearseniccadmiumchromiumcomponent separation methodconceptual modelconfidence levelcopperCroatiaDenmarkFerrarageostatisticsgroundwatergroundwater bodygroundwater levelgroundwater monitoringgroundwater qualityhexavalent chromiumItalian guidelinesLanzo MassifLOQmodified Lepeltier methodn/anatural backgroundnatural background levelnatural background levelsneutral mine drainagenickelnitratesophiolitesparameters estimationpre-selection methodpreselectionprobability plotsite-specific datasites under remediationsoftware implementationspatial distribution modelingstatistical methodst-testtrace elementtrace metalsultramafic rockswater qualityzincEnvironmental economicsPollution controlResearch & information: generalPreziosi Elisabettaedt1314100Rotiroti MarcoedtCondesso de Melo M.
