Abstract
Many communities in Pakistan use unsafe water polluted by domestic or industrial activities. Water treatment infrastructure is hardly in place, while the country’s socioeconomics jeopardizes its maintenance and improvement. Especially in rural areas, any cost-effective and passive solution to improve water quality is a boon. Here we present the successful application of a full-scale floating treatment wetland (FTW) for attenuating the pollutant concentration in a crude oil wastewater pit. Floating rafts, covering about 1/3 of the pit’s water surface area (10,000 m 2 ), were established using indigenous wetland plants. Successful removal of organics (>97%), hydrocarbons (99.6%), total dissolved solids (82%), heavy metals, and toxicity was recorded within six-months. Mass balance confirmed removal of organics up to 2.63 × 10 5, whereas carbon sequestration by FTW was 2.11 × 10 3 kg. About 500,000 m 3 of wastewater received treatment at a cost of US$0.0184 per m 3, which was later reduced to US$0.0033 per m 3 . A cross-sectional survey illuminated that application of the FTW positively impacted the lives of local communities. The FTW also became a new habitat for native bird species, thus underscoring the improved water quality and highlighting the study’s alignment with the United Nations Environment Program for better conditions for water supply and biodiversity.

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
