A phase II environmental site assessment is the sampling step that follows when records and a site walk leave an open question about contamination. Buyers, lenders, and sellers order it to determine whether a suspected release is in the soil, groundwater, or building materials, and at what level. Most properties never need one. When one does, the work is targeted, not a grid of random holes across the whole site.
Phase II work usually follows ASTM E1903. Where a Phase I Environmental Site Assessment looks at history, databases, interviews, and a site walk with no samples, a Phase II puts those findings to a laboratory test. A recognized environmental condition, or REC, means there is evidence of a release, a likely release, or a material threat of one. The Phase II answers whether that evidence shows up in the media that matter for the deal.
When a Phase II Is Warranted
A Phase I with no RECs usually ends the environmental review for a commercial closing. A Phase I with a REC does not prove contamination is present. It proves the question cannot be answered from paper and a walkover alone. Lenders and buyers sometimes also require sampling even when the Phase I language is cautious, especially on higher-risk property types or SBA deals.
Common Florida triggers include:
- Former or current underground petroleum tanks
- Dry cleaning or degreasing history
- Automotive, industrial, or maintenance shop use
- Agricultural land with long pesticide or herbicide use
- An adjacent property with a documented release
The Phase I recommendation should say what to investigate and why. That recommendation is what lets an engineer scope a Phase 2 Environmental Site Assessment tightly enough to be useful before closing.
What Phase II Sampling Usually Covers
Sampling is driven by site history, not by a one-size kit. Bechtol's Florida Phase II scopes typically look at three media when they fit the REC.
Soil
Borings are placed at the suspected source and along the pathway away from it. Field screening helps pick which intervals go to the lab. Depth and spacing follow what the Phase I found, not a standard grid drawn for every site.
Groundwater
Across much of Florida, groundwater sits shallow. That makes it both a likely pathway and a useful medium to sample. We install, develop, and sample monitoring wells, then analyze them for the contaminants the history points to.
Building materials
When a structure is part of the deal, or when renovation or demolition is planned, the same Phase II scope can include regulated building materials such as asbestos, lead-based paint, and PCBs. Sampling is coordinated with an accredited lab, and findings can sit in the same report rather than arriving as a separate surprise later.
Homeowners and buyers should not collect their own soil, groundwater, or asbestos samples. Chain of custody, drilling methods, well construction, and lab methods matter, and amateur sampling can miss the release or create a messy liability trail. Professional Phase II sampling is the right next step after a REC.
How the Investigation Is Designed
ASTM E1903 sets the frame. Professional judgment fills in the rest. The environmental professional matches drilling methods, sample locations, and analyte lists to the chemicals of concern, the local geology, and site access. Petroleum sites get petroleum analyses. Dry cleaner history points toward chlorinated solvents. Former grove land often needs metals and pesticide suites. Testing for every analyte on every boring is expensive and rarely informative. Testing for what the history indicates is the discipline.
Bechtol schedules the drilling and well installation in-house for most Phase II work, which keeps the field date tied to the closing calendar instead of waiting on a separate drilling contractor. Specialty access, soft ground, or shallow water can still call for a specialty rig under Bechtol supervision.
Laboratory work runs under chain of custody at a Florida-certified lab. Turnaround is usually about one to two weeks depending on the analytes, and expedited options are sometimes available when a closing date is firm. Field work itself is often only a few days once the crew is on site.
What the Phase II Report Is For
The report's job is to replace an open question with findings the parties can price. Results are compared against Florida Cleanup Target Levels. The report should state, in plain language, whether contamination is present above those levels, roughly how far the issue appears to extend based on the samples collected, and what options make sense next: no further action at this stage, more delineation, pricing or escrow language in the deal, or a move into regulatory assessment.
A Phase II that returns results below the relevant targets often closes the REC for transaction purposes without further action. A Phase II that confirms a release does not automatically kill a deal. Deals more often stall on uncertainty than on a quantified finding. Numbers can be escrowed, allocated, or used to reprice. An unanswered REC cannot.
If Contamination Is Confirmed in Florida
When sampling confirms a release, Florida properties often move onto an FDEP regulatory track under Rule 62-770 for petroleum contamination or Rule 62-780 for non-petroleum substances. That path is site assessment, and it can later include remediation and monitoring on a defined agency schedule. Bechtol's environmental engineering practice covers Phase I and Phase II ESAs, hazardous materials testing for lead and asbestos in building materials, and FDEP contamination assessment work. The important point for buyers mid-deal is that confirmed results have a process. They are not a dead end with no next step.
Frequently Asked Questions
What is a Phase II environmental site assessment?
It is the invasive sampling stage of environmental due diligence. After a Phase I identifies a recognized environmental condition, or when a lender or buyer requires sampling, a Phase II uses soil borings, groundwater wells, and sometimes building-material sampling to confirm whether hazardous substances or petroleum are present and at what concentrations.
How much does a Phase II environmental site assessment cost?
There is no single price, because scope drives the fee. The number of borings, whether monitoring wells are installed, how many lab analyses are run, and site access all change the job. A focused look at one former tank location is a different project from a multi-acre industrial parcel. Bechtol scopes Phase II work from the Phase I recommendation and the property details. Call 386.734.8444 or request a proposal with the site address and closing date.
How long does a Phase II environmental assessment take?
Field work is often one to three days once drilling is scheduled. Lab turnaround commonly runs one to two weeks, and the written report follows after results are interpreted. End to end, many Phase II projects take several weeks. Tell the team early if the schedule is tight.
What are the differences between a Phase I and Phase II Environmental Site Assessment?
A Phase 1 ESA is non-invasive. It uses records, historical research, a site reconnaissance, and interviews under ASTM E1527, and it asks whether there is reason to suspect contamination. A Phase II follows ASTM E1903, collects samples, and asks whether contamination is actually present and at what level. Phase I finds the question. Phase II tests the answer.
What is the difference between a Phase I and Phase II report?
A Phase I report documents RECs, historical RECs, controlled RECs, and de minimis conditions based on records and observations. It does not include soil or groundwater lab results. A Phase II report presents sampling methods, laboratory data, comparison to cleanup target levels, and conclusions about presence, approximate extent based on the samples collected, and recommended next steps for the transaction or for further assessment.
How long does a Phase II ESA take?
Plan on several weeks for a typical Florida Phase II that includes drilling, lab analysis, and reporting, unless the parties agree on an expedited lab schedule. The field portion is short compared with the laboratory wait. Bechtol can often mobilize drilling within days of scoping because the same firm that may have completed the Phase I also runs the borings.
Summary
A Phase II environmental site assessment turns a Phase I concern into measured data. Soil, groundwater, and, when needed, building materials are sampled against the history that raised the flag. Most sites never reach this step. When yours does, targeted professional sampling and a clear report give buyers, lenders, and sellers something they can act on before closing.
