Abstract
Surface water quality, particularly in rivers and lakes, has long been deteriorating due to various factors, including anthropogenic and natural activities.Herein, the Alhussein Water Treatment Plant is selected as a case study to assess the quality of treated water pumped to residents in Karbala City.The Weighted Arithmetic Index (WAI) method and the Canadian Council of Ministers of the Environment (CCME) method are used to calculate the Water Quality Index (WQI).The water quality and efficiency of the Alhussein Water Treatment Plant are assessed based on seven chemical and physical parameters: Total Dissolved Solids (TDS), pH, Turbidity, Sulphates (SO), Electrical Conductivity (EC), Chloride, and Total Hardness.Four measurement points were selected at different distances from the Alhussein Water Treatment Plant at three different times: 9 am, 1 pm, and 4 pm.Based on the current findings, regarding the measurement time in the early morning (9 am), water quality ranges from good to excellent.Generally, the water quality of the plant is acceptable and can be trusted for various uses, as the average WQI across all measurement sites is 74.This study recommends that investigating the specific sources of pollution is essential for devising targeted mitigation strategies, such as improving wastewater treatment and reducing industrial or agricultural runoff.

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
