What changed on real sites. In numbers.
How owners, operators, consultants and legal teams used Statvis to close sites, cut liability estimates and find the evidence that settled a dispute. Client names stay confidential; the numbers are theirs.
Case studies
Site closure · Midstream operator
The salt was natural background. Excavation fell by 74%.
Salinity fingerprinting across a sour gas plant's own historical record showed naturally occurring background, which supported adjusting the guidelines applied to its closure.
Remediation planning · Mining company
4,900 pages to a revised remediation plan, in two and a half days.
Every APEC and contaminant of concern in decades of reports, compared against risk-based guidelines. The site met them with no further work.
Due diligence · Midstream company
Asset retirement estimates for a whole deal, in days.
A site-by-site, cited ARO estimate for every asset in a transaction, with the highest-risk sites flagged for a full historical review.
Liability assessment · Site owner portfolio
A $45M liability estimate, under $15M on the first pass.
Site-specific liability assessments rebuilt from each site’s own record, every assumption cited, updated as new reports arrive.
Source apportionment · USEPA Superfund site
One buried image, worth tens of millions.
A search for pesticides surfaced a site map labelled “insecticide storage”, which helped identify another responsible party.
Data review · Superfund site
One PCB batch that didn’t fit, found before it shaped the decisions.
Profile comparison across the full congener dataset isolated one analytical batch that had passed validation but didn’t match the site.
Source identification · Former oil and gas facility
The PAHs matched the coal seam, not the facility.
Fingerprints, ratios and weathering showed coal, and a coal-seam control matched every site sample at more than 99%.
Records · Multinational energy company
78,000 site documents, renamed to one standard.
Every scanned document had to follow a strict corporate naming standard before it entered the records system, across 300 sites.
More case studies are in review with clients. We publish results only with permission.
