Phase II Environmental Site AssessmentEvaluación Ambiental de Sitio Fase II

When Phase I identifies recognized environmental conditions, Phase II confirms whether contamination exists. Subsurface investigations with soil borings, groundwater monitoring wells, and laboratory analysis — all performed locally in Puerto Rico.Cuando la Fase I identifica condiciones ambientales reconocidas, la Fase II confirma si existe contaminación. Investigaciones del subsuelo con perforaciones, pozos de monitoreo de aguas subterráneas y análisis de laboratorio — todo realizado localmente en Puerto Rico.

Subsurface Investigation & SamplingInvestigación y Muestreo del Subsuelo

A Phase II ESA involves the physical collection and laboratory analysis of soil, groundwater, and soil vapor samples to determine whether contamination exists at a property. It moves from historical research to hard data.

AES designs each Phase II investigation based on the specific RECs identified in the Phase I assessment. Our sampling plans target suspected source areas, migration pathways, and potential receptors.

Because our laboratory and field teams are both based in Puerto Rico, we deliver faster turnaround and tighter coordination than mainland firms shipping samples off-island.

Phase II CapabilitiesCapacidades Fase II

Soil boring and sampling (hand auger, direct-push, hollow-stem auger)
Groundwater monitoring well installation and sampling
Soil vapor sampling and analysis
Contaminant delineation and plume mapping
Risk assessment and exposure pathway evaluation
Remediation feasibility analysis
Regulatory reporting (EPA, JCA)
Expert witness and litigation support

The Process

How a Phase II ESA Works

Work PlanPlan de Trabajo

Frequently Asked QuestionsPreguntas Frecuentes

Common QuestionsPreguntas Comunes

Typically recommended when a Phase I identifies recognized environmental conditions (RECs) — evidence of potential contamination warranting investigation.

Subsurface soil sampling, groundwater monitoring well installation, laboratory analysis, and a written report with findings and recommendations.

Typical turnaround is 3–4 weeks including field work, lab analysis, and report preparation. Timelines depend on site complexity.

We provide recommendations for remedial action, additional delineation, or risk assessment. We can manage the full remediation process.
