Phase II Contaminant Investigations
Investigate potential contamination and understand your next steps
When a Phase I assessment or other information identifies a potential environmental concern, further investigation may be needed. OGI Environmental provides Phase II Environmental Site Assessments and contaminant investigations throughout Nevada.
We develop a site-specific scope to evaluate whether contamination is present and, where appropriate, investigate its nature and extent. The approach depends on the property’s history, suspected contaminants, existing information and project objectives.
What an investigation may include
- Review of previous environmental reports and available site information.
- Development of a sampling and investigation plan.
- Coordination and oversight of drilling, soil borings and monitoring well installation.
- Collection of soil, soil gas, groundwater and indoor air samples.
- Laboratory analysis and interpretation of analytical results.
- A written report documenting the work, findings, limitations and recommended next steps.
Not every property requires the same investigation. We confirm the proposed scope, fee and anticipated schedule before work begins.
Properties and concerns we investigate
Our experience includes properties associated with fuel storage, automotive operations, dry cleaning, manufacturing and other activities that may affect soil or groundwater.
Investigations may follow a Phase I ESA or address an already identified concern, such as a known release or findings from an earlier investigation.
From laboratory results to practical recommendations
OGI evaluates analytical results alongside site conditions and project requirements. Findings may indicate a need for additional investigation, regulatory coordination or evaluation of cleanup options.
When further action is appropriate, we can assist with additional characterization, remedial action planning and implementation, and coordination with the relevant agencies.
