Phase II Quantitative Assessment • U.S. Army Public Health Command (Provisional) Phase II Approach • Develop installation-specific HSP and APPs • Develop DQOs • Develop QAPPs using UFP-QAPP • Identify and address applicable SW and GW pathways only • Develop detailed Viable Pathway CSMs (discussion and illustration) - Incorporate non-range influences and degradation - Select effective sample locations • GW sampling at/near sources (not on impact areas) or exposure points • SW sampling - Account for temporal variability (wet/dry seasons, high/low flow events) - Use SW decision flow chart
Phase II Quantitative Assessment • USAPHC (Provisional) Phase II Approach (continued) • Ecological Risk Assessments – aquatic receptors only - Background and 95% UCL of mean results vs. screening levels comparison - Benthic macroinvertebrate surveys – false Positive / Negative • Human Health Risk Evaluations - Initial data screening – direct comparison to screening levels - Quantitative data screening – determine need for HHRA • Referred categorization must be based on Risk Assessment results – not just on Phase II data
