Groundwater

Within some data limitations, the paper provides a first assessment of areas in Australia with potential for implementing desalination technologies to supply agricultural water. At the national scale, these areas were identified based on a set of selected criteria: distance from land currently used fo

The feasibility of silica removal in RO treatment of groundwater from a Western Australian mining and processing operation to prevent scaling and enhance water recovery was investigated. This study has shown that it is possible to decrease the silica concentration in RO concentrate to levels that wo

Like other regions around the world, southern Brazil has experienced periods of drought, having to find alternative water resources for producing drinking water during these times. The deep wells drilled in the Guarani Aquifer could help with this water imbalance, but the water, in some places, is br

In sub-Saharan Africa 85% of those without access to safe water live in rural areas where the consequent poverty and ill health disproportionately affect women and children. The widespread development of groundwater is the most affordable and sustainable way of improving access to secure water for t

Arsenic is a serious problem in groundwater in Bangladesh, West Bengal, and other regions, with up to 100 million people worldwide estimated to be at risk. Long term consumption leads to arsenicosis, skin lesions and cancers. There is a clear need for cheap, simple, non-toxic field test kits for rou

Groundwater is a vital natural resource for provision of potable water in both the urban and rural environment. Pollution of groundwater may come from urbanization, industrial development, agricultural and mining activities, and also from natural sources. The soil strata have the capacity to attenua

Bongo faces a serious problem with its underground water supply. This paper examined the factors accounting for the poor water situation in the Bongo District. Bongo is in the Upper East Region of Ghana. Data was collected from the Water and Sanitation Committees and District Water and Sanitation Te

The removal of nitrate from aqueous solutions of a synthetic medium and groundwater was examined using various aquatic plants, such as water hyacinth, water lettuce and salvinia. Water hyacinth reduced the nitrate level to 64% in a synthetic medium containing 100 mg l–1 of nitrate. The efficiency of

Influence of dissolved organic carbon (DOC) on the quantitative estimation of Pu-239+240 in the groundwater was investigated. Impact of DOC in the range of 5–30 ppm was studied in solutions which were directly taken from different wells, whereas to conduct the experiment at the elevated level of DOC

The aim of this work is the performance study of the various stages of groundwater treatment in a pharmaceutical industry. We were particularly interested in the influence of the reverse osmosis on the data processing sequence. The water quality was evaluated in terms of conductivity; the performanc
