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.

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. Brownfield Log 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.
This is a sample log. Open your workspace to store real manifests, upload attachments securely, and share projects with your crew.
Fillable waste shipment manifest
Fill it on screen, print it for the driver, or download a copy for your compliance file. Leave fields blank to print a clean form to complete by hand in the field.
