E1527-21
ASTM compliant — Phase I exhibits and supporting layers
Phase I ESA Support
ASTM E1527-21 compliant assessments with GIS-integrated site analysis.
Environmental Due Diligence
Environmental maps and reports built for decisions
We help teams turn environmental data into defensible spatial evidence — ranked sites, monitoring dashboards, field-review targets, and briefing-ready maps for Phase I ESA and regulatory work.

The status quo
Why traditional Phase I reports fall short
- Desktop reviews miss contamination risks that spatial analysis catches
- Generic templates don't account for local soil, groundwater, or historical land-use data
- Firms pay for reports that don't hold up under regulatory scrutiny
What we deliver
What we deliver
02
Contamination Mapping
Spatial analysis of historical land use, underground storage tanks, and release sites.
03
Environmental Equity Screening
Priority maps for vulnerable areas with visible evidence, confidence levels, and review boundaries.
04
Change Detection & Monitoring
Before-after maps and dashboards with automatic change and exception detection.
05
Field & Drone Evidence
AOI maps, flight plans, and QA layers that support field teams with export-ready data.
Proof-led positioning
What this page needs to make obvious
Phase I ESA GIS, environmental site assessment maps, contamination mapping, and regulatory risk mapping.
Parcel and regulatory context
Buffers, nearby records, site history, adjacent uses, and evidence tables.
Environmental monitoring
Change detection, flood exposure, soil suitability, vegetation, erosion, and land-use shifts.
Report support
Maps, evidence notes, source citations, limitations, and exhibit-ready exports.
Proof workflow
Input, review, evidence, output.
Modeled on the live Geospatial Solutions demos: the page should show what the buyer sends, what they review, what evidence stays visible, and what they receive.
Input
Address, parcel, polygon, site question, required report context, and regulatory concerns.
Review surface
We map nearby records, soil/site constraints, historical change, flood or environmental context, and limitations.
Evidence
Each map layer includes source notes, distance/context, caveats, and recommended next check.
Output
Report-ready map packet, evidence table, GIS layer, and scoping recommendation.
Source and limits
Technical trust should stay visible.
Confidence
Spatial evidence supports due diligence but should not overclaim professional conclusions.
Caveat
Use wording as Phase I ESA support unless professional-of-record scope is explicitly defined.
Source
Parcel data, USDA soil, EPA/state records, local datasets, historical imagery, flood and environmental layers.
QA boundary
Source citations, buffer logic, limitation notes, and map review.
Export path
Report-ready maps, evidence table, PDF-style packet, GIS layers, and next-check list.
Before the first call
What you send · What you get
No vague discovery phase. You bring four or five things, we return a specific plan you can evaluate.
→ What you send
- 1Site address, parcel ID, or polygon
- 2Scope (Phase I exhibit, monitoring, equity screening)
- 3Deadline and EPR contact
- 4Any prior environmental reports for the site
← What you get back
- 1Regulatory database hit list (EPA + state UST/LUST/RCRA/NPL)
- 2Historical land-use summary with mapped change events
- 3Proximate release site map with distance and direction
- 4ASTM E1527-21 compliance checklist
- 5Recommended exhibit set with timeline and pricing
Deliverables
What you walk away with
- ASTM E1527-21 compliant Phase I exhibits and supporting GIS layers
- Regulatory database integration (EPA CERCLIS / RCRA / state UST-LUST)
- Contamination overlays, plume direction analysis, and risk visualization
- Full metadata and processing logs preserved for regulatory defense
How we work
A scoped path from sample data to running system
No open-ended retainers. No "discovery phases" that bill for months without producing anything you can evaluate.
-
01
Site intake
You send the address, parcel ID, or polygon. We confirm the AOI and pull the regulatory framework that applies to the site.
-
02
Spatial analysis
Regulatory database joins (EPA, state UST/LUST, NPL, brownfields), historical land use, plume direction, proximate release sites — all mapped.
-
03
Report
ASTM E1527-21 compliant deliverables: Phase I exhibits, GIS layers, contamination overlays, and a written narrative your EPR can sponsor.
-
04
Defend
If the report is challenged, we stay available — full metadata, processing logs, and source citations are preserved on every deliverable.

Questions teams ask before they engage us
Common questions, answered honestly
Are you replacing my environmental professional (EP)?
No. We provide the GIS-integrated spatial analysis and exhibits that your EP sponsors and signs. Our work strengthens the report; your EP retains professional responsibility.
Which states do you work in?
All 50, with deeper experience in DC, MD, VA, NY, NJ, CA, TX, and FL. State-specific regulatory database integration is part of the project setup.
How fast can you turn around a Phase I exhibit set?
Standard turnaround is 7-10 business days from site intake. Rush work (3-5 business days) is available with surcharge. Trial- or litigation-ready exhibits with full chain-of-custody documentation typically run 2-3 weeks.
What if the property has historical contamination?
We map the historical land use, identified release sites, regulatory boundaries, and proximate impacts. The spatial evidence supports the EP's risk determination and provides defensible documentation if the assessment is challenged.
