The potential of water resources contamination around a large-scale gold mine
(NM-AIST, 2022-05)
This study used the hydro-chemical properties and isotopic signatures of water to understand the
main sources of deterioration of water quality around the North Mara gold mine in Tarime
District, Mara Region. The ...
Contamination assessment and optimization of coagulation-flocculation-sedimentation water treatment process for Kou river in northern Tanzania
(NM-AIST, 2022-06)
The Babati Urban Water Supply and Sanitation Authority (BAWASA) in northern Tanzania
supplies water from the Kou River to Magugu town for domestic purpose, where its Fe (3.64
mg/L) and turbidity (87 NTU) concentrations ...
Water use and crop water productivity in farmer managed irrigation schemes across agro ecological zones of usa river catchment
(NM-AIST, 2021-11)
The Usa River Catchment is the potential area dealing with traditional irrigated agriculture.
This study aims to estimate the amount of water abstracted for and yield that reflect water
values to enhance crop water ...
Diversity and quantity of macro-and microplastics in irrigation farms sourcing water from an urban river: a case of Arusha Tanzania
(NM-AIST, 2021-10)
Increased concentration of plastics in urban rivers and agricultural farms causes degradation
of river system functionality and reduces the productivity of agricultural soils, respectively.
This study assessed the ...
Influence of land use change on nitrate sources and pollutant enrichment in surface and groundwater of a growing urban areas
(NM-AIST, 2022-07)
In the present study, three-year (1997, 2008 and 2017) satellite images as well as different hydro chemical parameters, nitrogen and oxygen isotopic composition of nitrate were used to examine
the impacts of land use and ...
Evaluation of recharge areas of Arusha aquifer, northern Tanzania: application of water isotope tracers
(NM-AIST, 2022-01)
In Arusha urban, northern Tanzania, groundwater contributes about 80% of the water supply.
However, elevated fluoride levels and evidence of anthropogenic pollution have been reported
in the groundwater around Mount ...
Impacts of irrigation water quality, associated soils characteristics and on-farm practices on paddy yields
(NM-AIST, 2022-07)
In this study, the impacts of irrigation water quality, soil characteristics and on-farm practices
on paddy yields were investigated. Standard spectroscopy and spectrometry methods were used
to analyze irrigation water ...
Strength and durability properties of concrete blended with pumice and scoria under combined attack of sulphate and chloride
(NM-AIST, 2021-11)
Concrete structures suffer serious deterioration under corrosive environment. Consequently,
the safety of these concrete structures is decreased. The influence of natural pumice (NP) and
natural scoria (NS) as supplementing ...
Fluoride and pathogens removal from water using combined electrocoagulation-inline-electrolytic disinfection process
(NM-AIST, 2024-08)
The consecutive removal of fluoride (defluoridation) and pathogens (disinfection) in drinking
water through combined electrocoagulation-inline-electrolytic disinfection (EC–ECl2) process
with aluminum and dimension-stable ...
Design of an evaporative cooling system integrated with ultraviolet light for preservation of fruits and vegetables at variable tropical weather conditions: a case study of Arusha, Tanzania
(NM-AIST, 2024-07)
Problems with fruits and vegetables spoiling after harvest are particularly acute in tropical
regions. This research presents the design, construction, and performance assessment of a
solar-powered evaporative cooling ...
