Our ability to identify and manage riparian sites for groundwater nitrate (NOAh) removal is limited by uncertainty surrounding the relative importance of plant uptake vs. microbially mediated removal processes. Microcosm studies often demonstrate negligible transformation rates in the subsoil of riparian forests, even in situations where groundwater well networks showed substantial groundwater ...

douala metropolitan city loated in the littoral province of cameroon,has experienced a rapid urbaniation and industralisation. the city depends heavily on groundwater as a resource. due to ubiquitous sources of pollution, groundwater quality and contamination has become an imprtant issue for this urban groundwater supply. this study uses the major ion chemistry of groundwater together with t...

Local groundwater in coastal aquifers in Shenzhen has experienced heavy pumping since the 1980’s when Shenzhen began to expand very quickly from a fishing village to a modern city but lacked a public water supply. Meanwhile, large-scale land reclamation was carried out to meet the needs of various urbanization projects. In this paper we analyzed groundwater from a coastal aquifer system in Shen...

OBJECTIVE To examine the impact of the severity of a child's chronic condition on family functioning from the perspectives of mothers and fathers and to compare their reports with the functioning of families with healthy children. METHODS Mothers and fathers in two-parent families of 160 infants and 102 pre-adolescents with a wide range of chronic health conditions (noncategorical approach) c...

BACKGROUND Most groundwater conservation and management efforts focus on protecting groundwater for drinking water and for other human uses with little understanding or focus on the ecosystems that depend on groundwater. However, groundwater plays an integral role in sustaining certain types of aquatic, terrestrial and coastal ecosystems, and their associated landscapes. Our aim was to illumina...

Keywords: Climate impacts Groundwater hydrology Infiltration Water supply Isotopes s u m m a r y High elevation groundwater basins in the western United States are facing changes in the amount and timing of snowmelt due to climate change. The objective of this study is to examine seasonal variability in a high elevation aquifer (Martis Valley Watershed near Truckee, CA) by analyzing (1) tritium...
