Abstract
In this study, eight samples were analyzed along Al-Abbasia River, where the Water Quality Index and pollution or changes in water quality were studied. The Water Quality Index is a useful and rapid technique for evaluating the quality of any water source. The samples were taken along Al-Abbasia River and on the area basis which influence the river. The physical and chemical parameters (pH, Turbidity, Alkalinity, Electrical Conductivity, Total Disollved Solids, Total Hardness, Ca2+, Total Suspended Solids, Na+, Cl-, K+, SO42-, Mg2+) were evaluated in this study using the Weighted Arithmetic Water Quality Index and Canadian Council of Ministers of the Environment Water Quality Index methods which shows the extent of pollution. According to Weighted Arithmetic Water Quality Index, the water quality is classified as poor except for the second sample, where it was classified as Very poor (according to the standards of the WHO), while according to the Canadian Council of Ministers of the Environment Water Quality Index method, the water of Al-Abbasia river was often classified as a Good, except for the second and forth samples they were classified Fair. This study showed that the main cause of the deterioration of water quality in Al-Abbasia River is the direct discharge of sewage, human activity, and harmful residues of pesticides and materials which used in agriculture.

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 it
