Abstract

fetched live from OpenAlex

Too many drinking water and wastewater systems across Canada threaten public health and the environment. In this report, the author writes that many of the municipally owned and operated systems that treat and distribute drinking water perform poorly and lack the financial resources and expertise to meet the challenges posed by aging infrastructure. Indeed, more than 1, 000 systems across Canada violate provincial requirements or are subject to boil-water advisories. Brubaker recommends reforms to the financing and operating of utilities to ensure their long-term sustainability. These include introducing competition for water and wastewater services and taking steps to attract more private expertise and capital investment.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
