Phase 2 Environmental Site Assessments (ESAs)
Sampling and testing to investigate concerns a phase 1 raised
When a phase 1 identifies a potential environmental concern, a phase 2 environmental site assessment investigates it directly through sampling and laboratory testing. Colman Engineering designs and carries out phase 2 investigations across Virginia to determine whether contamination is present and, if so, its nature and extent. The findings give you the factual basis for decisions about a property.

Phase 2 Environmental Site Assessments (ESAs)
Answers backed by data
Instead of open questions, you get sampling results that show whether contamination is present. That evidence supports clearer decisions about purchase, cleanup, or development.
Targeted, cost-aware investigation
We design the sampling plan around the specific concerns identified, focusing effort where it matters so you get the information you need without over-investigating.
A clear path forward
If results show a problem, we help you understand the options, whether that's further assessment, remediation planning, or renegotiation. You're never left with data and no direction.
From sampling plan to actionable findings
We start with the concerns flagged in the phase 1 and design a sampling plan to investigate them, whether that means soil borings, groundwater monitoring, or other media. Fieldwork is carried out and samples go to an accredited laboratory. We then interpret the results, describing whether contamination is present, its likely nature, and its extent. You receive a report that translates lab data into practical meaning, along with our recommendations for any next steps.
Use Cases
A phase 2 tends to be the appropriate next step once a concern has been identified and you need to know what's actually there.
01
Your phase 1 flagged a concern
A recognized environmental condition surfaced in the phase 1. A phase 2 investigates it directly so you know what you're dealing with.
02
You need to quantify a known issue
Contamination is suspected or partly known, and you need to understand its extent. Sampling defines the scope of the problem.
03
A transaction or lender needs certainty
A deal or financing hinges on resolving an environmental question. phase 2 data provides the factual footing to move forward.
Tips and FAQs
A phase 2 involves intrusive work like drilling and sampling, so site access and scheduling matter, and results depend on laboratory turnaround. The scope is shaped by what the phase 1 found, which is why the two work best in sequence. If contamination is confirmed, there may be reporting requirements and remediation options to consider. We can help interpret those implications once the results are available.
Do I always need a phase 2 after a phase 1?
No. A phase 2 is only warranted when the phase 1 identifies a recognized environmental condition worth investigating. Many phase 1 assessments conclude without one being needed.
What does a phase 2 actually test?
It depends on the concern, but commonly soil and groundwater, and sometimes soil vapor. We design the sampling around the specific issues your phase 1 identified.
How long does it take to get results?
Fieldwork is often completed in a matter of days, but laboratory analysis adds time. We give you a realistic timeline once the sampling plan is set.
What if contamination is found?
We help you understand the findings and options, which may include additional assessment or remediation planning. We can guide you on the practical and reporting considerations involved.
