Assessment of groundwater pollution using PIG index and microbiological indicators in the Angads plain, Morocco.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study assessed the hydrochemical quality of groundwater in the Angads plain using the pollution index of groundwater (PIG), and microbiological indicators. Two sampling campaigns were carried out in 2023 (wet and dry seasons), with 45 samples taken each year. The analyses revealed that the majority of the ions studied exceeded the limits recommended and authorized by the World Health Organization (WHO). The PIG revealed that over 80% of samples fall into the insignificant and low pollution categories, with pollution levels increasing during the dry season. Microbiological analyses revealed the presence of fecal coliforms (FC), total coliforms (TC), intestinal enterococci (IE) and sulfate-reducing clostridium (SRC) with average levels of 52, 80, 2, and 0 CFU/100 mL during the wet season, while during the dry season these values increased to 79, 120, 3, and 0 CFU/100 mL, respectively. This study offers vital information on groundwater pollution, enabling decision makers, residents, and scientists to better identify safe water sources and areas at risk. The findings highlight the urgency of implementing effective treatment solutions and devising sustainable management plans to preserve these water resources over the long term.
