Iran's Groundwater Hydrochemistry [PDF]

open access: yesEarth and Space Science, 2021
Iran's groundwater hydrochemistry has not been well understood. In this study, Iran's groundwater hydrochemistry is evaluated using a rich, ground‐trusted data sampled from 9,468 wells distributed across the country in 2011.

Exploring copepod distribution patterns at three nested spatial scales in a spring system. Habitat partitioning and potential for hydrological bioindication [PDF]

open access: yes, 2015
In groundwater-fed springs, habitat characteristics are primarily determined by a complex combination of geomorphic features and physico-chemical parameters, while species assemblages are even more intricate.

Tracking sources and fate of groundwater nitrate in Kisumu City and Kano Plains, Kenya [PDF]

open access: yes, 2020
Groundwater nitrate (NO3−) pollution sources and in situ attenuation were investigated in Kisumu city and Kano plains. Samples from 62 groundwater wells consisting of shallow wells (hand dug, depth 15 m) were obtained during wet (May–July 2017) and dry ...
