The potential cost-effectiveness of wetland restoration is assessed as a means of securing the carrying capacity of land for pastoralist communities of the Kamiesberg communal area in South Africa under projected future climate conditions. The conventional alternatives would be to respond to ...
[...]investigations, and had made reference to the site investigation information obtained before and during construction of the existing Brothers' Bridge in the project site,andsunkadditional boreholes to ascertain the extent of the rock levels underneath. ...
Field testing of the design in an existing borehole in the unconfined sandstone aquifer underlying the city of Nottingham (UK) demonstrates the efficacy of the design in fissured bedrock as significant hydrochemical variations are observed over a few metres in depth. The availability and low cost ...
for Pitcher Pump systems (suction pumps fitted onto hand-driven boreholes) is studied in an urban context in Madagascar, EMAS low-cost water supply technologies are assessed in Bolivia, and a technical comparison is completed with manual EMAS Pumps and family versions of the Rope Pump in ...
and consists of a field assessment of EMAS groundwater supply systems (handpumps on manually-driven boreholes) and rainwater harvesting systems as used at the household level in Bolivia, focusing on user experiences and the medium/long-term sustainability of the pump (cost, functionality, etc.)...
While not exempt from shortcomings, manually drilled boreholes have proven an opportunity for social and economic development. The main reasons explaining the expansion of manual drilling are affordability, suitable geology and hydrogeology, and a lack of alternatives. The only prerequisite in both ...
2.6.3. Effect of Real Water Sample Matrix To investigate the effect that the sample matrix has on the removal of Pb(II), 100 mL of real water samples from a borehole in Giyani, Limpopo province, were spiked with 10 mg/L of Pb(II). The pH of the solutions was adjusted as shown ...
frequent intermittency of ore and waste rocks in ore bodies and deposits require additional costs for in-mine exploration, testing of blast boreholes, ore blending prior to its processing (organization and maintenance of an in-between stockpile) and selective mining of industrial, cut-off grade (...
