“…The concentration of Ca 2+ was measured using a Aquamerck Calcium Kit (Merck) with an accuracy of ±0.1 mg/L. The concentration of DIC was measured using an Aquamerck Alkalinity Kit (Merck) with an accuracy of ±0.05 mmol/L ( Nzung’a et al, 2018 ).…”

“…A GIS-based approach proposes the results of the explicit and feasible multiscenarios, which facilitates the effective management of ecological space. The results show the spatial characteristics of eco-space for maintaining water security, biodiversity, disaster protection and recreation [74][75][76].…”

“…The ecological importance evaluation of regional space emphasizes the harmonious development between production space, living space, and ecological space, focuses on the symbiosis between humans and other organisms, and maintains the natural foundation of urban development using applied principles in ecology. Based on the analysis of ecological characteristics, ecological importance evaluation examines the spatial distribution of regional ecological importance and provides measures for preventing ecological security issues from regional development and construction [73][74][75][76]. A GIS-based approach proposes the results of the explicit and feasible multiscenarios, which facilitates the effective management of ecological space.…”

“…[20] Recorded elevated levels of Diazinon, Fenitrothion, Cyhalothrin, Malathion, bis (2-ethylhexyl) phthalate, Dimethoate while analyzing of organic contaminants and the physico-chemical properties of borehole water of Maili-nne Estate and Sosiani village, Uasin Gishu County, Kenya. [21] detected the following from Athi and Kauthulini River water sources; total coliforms mean ranged between 10 and 23,830 CFU/100 mL, Escherichia coli mean range between 10 and 3480 CFU/100 mL, Vibrio cholera, Shigella sp., Salmonella sp., Klebsiella sp., Streptococcus faecalis and Clostridium perfringens were also detected. [22] While assessing microbiological water quality of sand dams in southeastern Kenya indicated that the water from test holes and covered wells was microbiologically of better quality than the scoop holes with median TTC levels of 0/100 mL and 159/100 mL respectively.…”

“…[22] While assessing microbiological water quality of sand dams in southeastern Kenya indicated that the water from test holes and covered wells was microbiologically of better quality than the scoop holes with median TTC levels of 0/100 mL and 159/100 mL respectively. However, the median values of turbidity for both scoop holes (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) and covered wells (5-10 NTU) exceed the World Health Organisation (WHO) guideline values. In addition the conductivity of water from 23% of scoop holes and 26% of covered wells is above the recommended WHO limit.…”
