Assessment of Groundwater Quality over the Erbil Plain Based on Water Quality Index
Bibliographic record
Abstract
Groundwater is used for drinking, household and agricultural activities by the growers surrounding Erbil city. Therefore, it was necessary to determine its quality by measuring physical and chemical parameters according to standard method. Thus, water samples have been collected from sixteen wells during December 2016, March, Jun, and September 2017 within 1liter polyethylene bottles and transported to the laboratory for analysis and analyzed according to Canadian Water quality Index Formula (WQI). The WQI of groundwater was based on 22 parameters including pH, electrical conductivity, total hardness, calcium hardness, magnesium hardness, total alkalinity, chloride, dissolved oxygen, biological oxygen demand, sodium, potassium, sulphate, orthophosphate, nitrate, oil and grease, zinc, copper, iron, nickel, lead, cadmium and mercury. WQI was found to be 38.87, which indicates a poor quality that the water was not suitable for direct consumption and must be treated before use to avoid water-related diseases.

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.
