Do ponds cause arsenic-pollution of groundwater in the Bengal basin? An answer from West Bengal.
We report time-series data collected over two years for delta18O, delta2H, and Ca, Mg, K, and Cl, concentrations for 10 ponds in, and upflow of, an As-polluted region of southern West Bengal. We compare the compositions of As-polluted groundwaters from wells with the compositions of waters in ponds upflow, and within the range of influence, of the wells. Conservative tracers (delta18O, delta2H,...
متن کاملLarge groundwater strontium flux to the oceans from the Bengal Basin and the marine strontium isotope record.
Strontium concentration and isotopic data for subsurface flowing groundwaters of the Ganges-Brahmaputra (G-B) delta in the Bengal Basin demonstrate that this is a potentially significant source of strontium to the oceans, equal in magnitude to the dissolved strontium concentration carried to the oceans by the G-B river waters. The strontium concentrations of groundwaters are higher by a factor ...
متن کاملMeasurement of submarine groundwater discharge in Kahana Bay, O‘ahu, Hawai‘i
Submarine groundwater discharge (SGD) is neither well understood nor commonly investigated in Hawai‘i, but it is recognized as a potential pollution source to coastal environments. Between 1998 and 2000, this study located and quantified both total SGD and the terrestrial SGD fraction ( ftgw) in Kahana Bay, O‘ahu. CTD casts were used to profile the water structure and identify potential areas o...
متن کاملAcoustic reflections in the water column of Krishna-Godavari offshore basin, Bay of Bengal.
Seismic oceanographic studies from various oceans worldwide have indicated that the acoustic reflections are mostly observed along thermal boundaries within the water column. However, the authors present a case study of seismic data from Krishna-Godavari Basin which shows that salinity variations also play an important role in the occurrence of water column reflections. The observed reflection ...
متن کاملRegional hydrostratigraphy and groundwater flow modeling in the arsenic-affected areas of the western Bengal basin, West Bengal, India
The first documented interpretation of the regional-scale hydrostratigraphy and groundwater flow is presented for a ∼21,000-km area of the arsenic-affected districts of West Bengal [Murshidabad, Nadia, North 24 Parganas and South 24 Parganas (including Calcutta)], India. A hydrostratigraphic model demonstrates the presence of a continuous, semi-confined sand aquifer underlain by a thick clay aq...
