mahallat hot springs located in the northeast of mahallat, in central iran. there are 6 main hot springs namely shafa, abejoush, donbeh, soleimanie, hakim and soda. in this research, geology, physico-chemical characteristics and petrography of basement rocks of these hot springs have been investigated. the results show that hot springs have an average temperature of 45°c and acidic to neutral p...

The Pavas river valley basin is an agricultural and livestock region, located in the municipality of La Cumbre, Valle del Cauca department Colombia. inhabitants are supplied by piped water, which times water deficit may present limitations terms quantity quality, this has led to a transition towards exploitation use groundwater resources. This study used physicochemical microbiological analysis...

groundwater is the most widely distributed resource of the earth and groundwater quality evolves rapidly as it passes through the subsurface pathways within the unsaturated zone. increasing urbanization and anthropogenic activities have added to the problem of deficient amount of good quality groundwater. the study area is an industrial hub for textile sector. textile production, particularly d...

Groundwater and seepage samples were collected from both the natural and building-modified slopes in the highly urbanized spaces of the Mid-Levels area, Hong Kong. Groundwater in the natural slopes, although retaining some signatures from rainwater, is enriched in major cations such as Na, K, Ca and Mg and some anions such as HCO3 and SO4. Clearly, water-rock interactions, such as weathering of...

Water salinization changes hydrogeochemistry, affects the quality and quantity of groundwater available for human consumption its mitigation is time-consuming. A large brackish lagoon Atlantic Ocean surround aquifer São José do Norte town (Brazil). Population economic growth demand more domestic agricultural purposes, stressing aquifer. Despise aquifer’s social-economic status, potential impact...
