Firm Profile & Institutional Experience

Aptim Environmental & Infrastructure LLC (APTIM) is a leading provider of environmental, engineering, and infrastructure solutions with a robust presence in the state of Florida. Operating from a regional hub in Winter Garden, the firm leverages a deep bench of Professional Geologists (P.G.) and technical specialists specifically trained in Emerging Contaminant (PFAS) protocols.

APTIM's experience within the FDEP Waste Management and Site Investigation Section is extensive. The firm maintains specialized certifications for PFAS-free field activities, ensuring that sampling equipment and personal protective equipment (PPE) do not introduce cross-contamination in the field. This institutional rigor is mandatory for projects like the Citrus County Fire Training Center, where detection limits are often measured in parts per trillion (ppt).

Gaya's Note: The Karst Complexity

Lecanto, Florida, sits atop karst topography—a landscape characterized by soluble bedrock. PFAS migration here is unpredictable compared to clay-based soils.

Strategic Risk: In karst systems, contaminants can bypass soil filters through fractures and sinkholes. This is why the firm's Work Plan includes not just shallow soil (0-2') but also deep groundwater profiling using **SP-16 (Screen Point)** technology. APTIM is not merely identifying current locations; the firm is mapping future migration pathways.

Technical Scope of Work

Task 1: Work Plan & Strategy

APTIM developed this comprehensive Work Plan identifying 10 boring locations (6 Hand Auger, 4 Direct Push). This phase involves logistical coordination with Citrus County and utility clearance for safe intrusive assessment.

Task 2: Multi-Media Field Investigation

  • Soil (0-2 ft bls): Collection of samples at 0.0-0.5' and 0.5-2.0' intervals to map the impact of historical AFFF training.
  • Groundwater Profiling: Installation of SP-16 samplers at multiple vertical depths to delineate the vertical extent of the PFAS plume.
  • Surface Water & Sediment: Targeted sampling of the Eastern and Central Retention Areas to assess runoff and ecological accumulation.
