Assimilation of contaminant concentration data from shallow dug wells could help improving model behavior, eventually resulting in better forecasts.
Honeybee also built the rock-abrasion tool (or RAT), that the Opportunity uses for its own shallow digging.
Shallow dug or bored wells, located in sites where there is a thin soil profile or shallow water table, can be very vulnerable to contamination.
Subsequently, the daily demand for domestic water is met primarily by shallow dug wells.
The physicochemical data of groundwater highlighted distinct differences between shallow dug well, borewell and tap waters.
Depth mainly controls anions (SO4, HCO3) along with Na+ in deep tube wells; however, its role in shallow dug wells is independent (Fig. 6b).
This study intended to assess the extent of shallow dug wells (SDWs) utilization and contribution of IK on management of SAs of indigenous people of Dodoma Municipality.
Twenty-seven (27) water samples from boreholes (BHs), HD, Matumbulu dam (MD), shallow dug wells (SDWs) and the major tributaries leading to Little Kinyasungwe River (LKR) and which flows to HD; were collected in March , 2014
This remains the case when as much as 20 30% of Dodoma region is regarded suitable for shallow dug wells (SDWs) development (Baumann et al. 2005) and where SDWs occur widely in the region.
Dhaka Community Hospital and their affiliated clinics also worked with impacted villages to install arsenic-free water sources through shallow dug wells, larger Indira wells, filtered surface water, and rainwater harvesting (Joya et al. 2006; Quamruzzaman et al. 2001).
Contaminated surface water seems to be an important factor, as prevalence of CKDu is low (1.5%) where water is obtained from deep wells, natural springs and pipe-borne town water and the prevalence is high (7.7%) in those areas using shallow dug wells, stream water and water tanks.
