The platform
Everything a Brownfield project owes to the record.
EPA contaminant library
Search screening levels for soil, groundwater, and air across residential, industrial, and construction scenarios — with CAS numbers and citations.
Field logs that stick
Log samples, exceedances, and remediation actions from any device. Photos, GPS, and chain-of-custody attach automatically.
Agency-ready reports
One click generates NPL, ASTM Phase II, and state VCP reports formatted the way reviewers expect — no more re-typing spreadsheets.
Real-time exceedance alerts
The moment a reading crosses a federal or local threshold, the project lead knows — with the citation attached.
Contaminant library
Every threshold. Every medium.
A live index of EPA Regional Screening Levels, MCLs, and NAAQS — the numbers your project manager needs before crossing a fence line.
| Contaminant | Medium | EPA limit |
|---|---|---|
Pb Lead Soil | Residential soil | 200 mg/kg |
As Arsenic Soil | Industrial soil | 3.0 mg/kg |
Cd Cadmium Soil | Residential soil | 7.1 mg/kg |
Cr⁶⁺ Chromium VI Water | Groundwater MCL | 0.1 mg/L |
TCE Trichloroethylene Water | Groundwater MCL | 0.005 mg/L |
BaP Benzo(a)pyrene Soil | Residential soil | 0.1 mg/kg |
Hg Mercury Air | Ambient (NAAQS) | 0.3 µg/m³ |
PM₂.₅ Fine Particulate Air | 24-hr NAAQS | 35 µg/m³ |
Sample values shown. Full dataset (450k+ entries, quarterly EPA sync) unlocks with your account.
How it works
From scoping to sign-off, in the order agencies read it.
- 01
Scope the site
Import parcel boundaries, historical uses, and Phase I findings. Terrafield pre-fills likely contaminants of concern.
- 02
Log from the field
Techs record samples on phone or tablet. Readings map instantly against the correct EPA threshold.
- 03
Track remediation
Every excavation, capping event, and post-treatment sample lands on one auditable timeline.
- 04
File the report
Generate agency submittals — federal, state, or local — in the exact format each reviewer expects.
Manifest & disposal log
A defensible paper trail, from load-out to landfill.
Log every hazardous-waste manifest, disposal destination, and weight ticket in one place. Attach photocopies of the manifest, shipping document, and scale ticket so nothing goes missing before the agency asks.
Demo mode: entries and files live in this browser session only. Enable the full account to store manifests and attachments securely with per-project access.
