In order to understand the source of groundwater inrush and its hydrogeochemical evolution path truly, determine characteristics development trend water cycle, effectively solve problem disaster in mining area. this paper, Jiaozuo area, a typical large area North China type, is selected as study Taking Ordovician aquifer research object, Ca2+ hydrochemical equilibrium model limestone system est...

The presence of chlorinated solvents polluting groundwater in urbanized areas poses a significant environmental issue. This paper details thoughtful approach to remediate tetrachloroethylene (PCE) plume district that is characterized by complex hydrological context with limited accessibility. Through geodatabase-driven and coupled hydrogeochemical approach, two distinct remediation technologies...

An understanding of hydrological processes is vital for the sustainable management of groundwater resources, especially in areas where an aquifer interacts with surface water systems or where aquifer interconnectivity occurs. This is particularly important in areas that are subjected to frequent drought/flood cycles, such as the Cressbrook Creek catchment in Southeast Queensland, Australia. In ...

Prospective and operational mine water geothermal projects worldwide have faced challenges created by chemistry (e.g., iron scaling, corrosion) high expenditure costs drilling or pumping costs) among others. Gravity fed actively pumped drainages can be cheaper sources of low-carbon heating when coupled with adequately sized heat exchanger pump hardware. They also provide valuable chemical data ...

Coastal aquifers are strategic and fundamental in the development of touristic areas. The coastal aquifer within Manglaralto River Basin Ecuador is essential, as it only source water supply for a large part northern Santa Elena province. It semi-arid region where high volumes pumped from aquifer, causing significant drawdown groundwater levels, thus affecting quality. This work aims to characte...

This paper introduces new insights into the hydrochemical functioning of lowland river systems using fieldbased spectrophotometric and electrode technologies. The streamwater concentrations of nitrogen species and phosphorus fractions were measured at hourly intervals on a continuous basis at two contrasting sites on tributaries of the River Thames – one draining a rural catchment, the River En...

Groundwater (GW) is a significant freshwater resource for domestic, industrial and irrigation water supply in the India. During last decades, the demand of groundwater supply for drinking, domestic, irrigation, industrial and multipurpose uses has increased due to the rapidly rising population and constant desire for a better lifestyle in developing countries. Increasing demand for fresh water ...

Geophysical and hydrochemical surveys were used to investigate the hydrogeological conditions in one of the Rı́o Sucio microbasins, in central Nicaragua. Zones of vertical structures (i.e. fractures and quartz veins) and weathering were mapped using Continuous Vertical Electrical Soundings (CVES), as such zones are of major importance for groundwater transport. Water from the springs was analyse...
