Hydrochemical facies study of ground water in the Tucson Basin
The concept of hydrochemical facies is used to study the distribution and, indirectly, to identify the origin of the chemical character of ground water in the basin-fill aquifer of the Tucson Basin in relationship to the hydrogeologic framework. Hydrochemical fades of ground water is defined …

The hydrochemical and isotopic characterization of groundwater in southern Mozambique
… this study was to characterize the isotopic and hydrochemical composition of groundwater in the southern Mozambique study area, using major ions and stable isotopes. Samples were categorized into different zones based on the underlying geology in which the borehole was sited. Overall, the …

Hydrological and Hydrochemical Responses From Thawing Permafrost in the Canadian Arctic
The objectives of this research are to better understand: (1) how Arctic watersheds respond in terms of hydrological processes to deepening active layers, (2) what the short and long-term changes are to surface water chemistry in watersheds impacted by thermal and physical permafrost disturbances, …

Hydrogeological and Hydrochemical Characterization of the Matozinhos-Pedro Leopoldo Karst, Brazil
… Mata Creek, a tributary of the Velhas River. Hydrochemical monitoring in four of the major springs showed that groundwater quality for the measured parameters in the discharge zone is generally good, despite the heavy industrialization and occupation in some of the recharge areas. Conduit flow …

Hydrochemical Dynamics Under Differing Winter Climate Regimes at the Hubbard Brook Experiment Forest
<p>This dissertation is a two-phase study of the hydrochemical dynamics of drainage waters at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire, USA, that aims to improve understanding of changes in water quality associated with winter climate variation. The first phase was an analysis …

Hydrochemical Assessment and Modelling of Groundwater Quality of an Urban Aquifer Near A Sanitary Landfill
Groundwater supply is crucial to both anthropogenic and industrial activities in Canada. In Saskatchewan, around 63 percent of municipalities rely on groundwater as their primary water supplies. Recent data suggested groundwater quality in Condie aquifer might have been compromised due to the …

Evaluation of storage strategies and techniques for the hydrochemical analysis of nutrients in Atlantic Ocean coastal water samples
Filtered and unfiltered samples of coastal seawater from the Atlantic Ocean (Muizenberg and Llandudno beaches, Cape Town) representing a non upwelling region and an upwelling region respectively were stored at -20 deg C. Deviations in the concentrations of silicate, inorganic phosphate, nitrite, …
