Quality valuation and hydrogeochemical features of groundwater in university campus and its surroundings, south-west Nigeria.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Groundwater is an important freshwater source that can be utilized for domestic and many more purposes. This study assesses the quality and hydrogeochemical processes of shallow aquifer units in the Federal University of Agriculture, Abeokuta (Nigeria) and its localities. Groundwater chemistry, multivariate statistical techniques and water suitability indices have been utilized to appraise groundwater quality. To achieve the objective, hydrochemical analysis, water quality index (WQI), irrigation potential index (IPI) and corrosivity index (CI), have been studied. Thirty groundwater samples were drawn from hand-dug wells and analyzed for physico-chemical parameters using standard laboratory methods. Most of the tested quality parameters fell within the global health regulatory organization recommendations for safe potable water. The average abundance order of dominant cations and anions are [Formula: see text] and [Formula: see text], respectively. Subtle alterations in groundwater chemistry were attributed to silicate weathering, ion exchange reaction and slight localized human-induced inputs. Hydrochemical facies analysis using a Piper diagram showed that the dominant groundwater type were [Formula: see text] and mixed [Formula: see text], typically associated with rock-water interaction, and recently recharged groundwater influenced by silicate rock dissolution. By the WQI results, 97% of the groundwater samples belong to ‘excellent to good’ category while the remaining 3% (sample OS2) belongs to ‘poor’ water quality. In terms of agricultural usability, over 50% of the groundwater samples were deemed suitable for irrigation. However, concerns were noted in relation to sodium percentage (Na%), soluble sodium percentage (SSP) and kelly ratio (KR), which could impact soil health over prolonged use.
