Abstract
The results of a 3-year six sigma evaluation of a centralized corporate remediation data management system are presented. The primary focus of the study is to improve electronic management of remediation data generated for the corporate environmental remediation function. The examination is unique in that no prior body of work has applied six sigma methods to environmental remediation data management. Both qualitative and quantitative six sigma tools have been applied in the study. Metrics are presented illustrating significant improvements in cost, quality, and cycle time since implementation of the system. A cost function is derived to predict normalized costs for data management as a function of the number of records in a database based upon a statistical population of 110 remediation sites and over 11 million records. The importance of remediation data management is examined within the context of process sustainability from the standpoint of protection of human health and environment, improved regulatory compliance, and greater transparency. The study is relevant to the state of environmental remediation within the context of more stringent enforcement through the regulatory agencies and the courts, an intensifying complexity of state and federal electronic data delivery (EDD) requirements, a ratcheting downward of cleanup standards, lower analytical detection levels, increasing requirements for capture and retention of analytical metadata, continued reliance on containment and institutional controls, and a parallel increasing demand for data that quantifies the nature, extent, and temporal variability of contamination. Application of six sigma metrics results in more-effective institutional stewardship manifested by reduced cycle time, significantly reduced cost, and enhanced data quality and defensibility through the long-term remediation lifecycle, which can span decades. A case study is presented for a complex, multimillion-dollar site remediation effort.

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
