Assessment of Surface Water Quality: The Perspective of the Weija Dam in Ghana
Bibliographic record
Abstract
Investigations into the water quality from the Weija Dam have been carried out. The inhabitants around the dam use the water for drinking and irrigation mainly, apart from fishing activities. Twenty five samples were collected and standard methods were used for the measurement of physical and chemical parameters. The ionic dominance pattern for cation and anion was Na+ >K+ > Ca2+ > Mg2+and HCO3- >Cl- >SO42- respectively. The ionic dominance pattern of the study area was in contrast with the ionic dominance pattern of Ca2+ > Mg2+ > Na+> K+ and HCO3- > SO42-> Cl- for fresh water and Na+ > Mg2+ > Ca2+ > K+ and Cl- > SO42-> HCO3- for sea water. Generally, anthropogenic activities along the Densu river basin and rock weathering, as opposed to evaporation-crystallisation and precipitation, could be the source of major ions in the dam. The hydrochemistry gives an indication that the water is soft and suitable for domestic use. The water was also found to be useful for irrigation without prior dilution with low salinity waters.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
