Abstract
The contamination footprint from munition disposal sites will be dependent on the type and quantity of munitions requiring disposal, and the available disposal methods. The discovery of a groundwater perchlorate plume at the Canadian munition logistical disposal site led to a 3-year investigation into the disposal activities of perchlorate containing munitions and the associated contamination footprint on various media. More specifically, this investigation included a comprehensive study of cumulative soil and groundwater contamination coupled with air emission measurements. The assessment included adapting soil sampling techniques to a post-disposal context, enabling a more precise assessment of impact. Furthermore, various disposal methods were tested to understand their respective contributions to the contamination footprint. This work extended to the evaluation of air emissions to identify disposal limits essential for meeting provincial air quality standards. Our analysis facilitated the formulation of an effective management strategy to mitigate airborne contamination risks and associated impacts to human health. The evaluation of perchlorate inputs into groundwater was paramount in understanding cumulative impacts and devising long-term management strategies for the site. Insights gained from this assessment provided crucial data for anticipating the trajectory of contaminant migration and implementing proactive management measures. Although the evaluation was a comprehensive effort to understand the contamination impact of disposing perchlorate containing munitions, future work should include the evaluation of novel munitions particularly emerging contaminants such as energetics in insensitive munitions. Adding this assessment and integrating results into future strategies is useful for futureproofing the contamination footprint. This holistic evaluation shows the complexity of managing and forecasting environmental contamination at logistical disposal sites. The integration of diverse methodologies and models offers a robust framework for safeguarding environmental health and fostering sustainable management practices in the face of evolving challenges.

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
