Find where the contamination came from. Show the chemistry behind it.
Generic guidelines often overstate risk, and mixed sources are hard to untangle. Chemical fingerprinting separates sources from each other and from natural background, sample by sample, and builds the evidence for a site-specific approach.
More than one PFAS source? Tell them apart, sample by sample.
Hierarchical clustering groups samples by their PFAS profile. Click a cluster to see its fingerprint and where those wells sit on the map; different sources show different signatures.
- PFAS profiles clustered across every sample
- Fingerprints compared side by side
- Clusters linked to the map
Salt impacts across your site? Show what is background and what is not.
Group samples by their ionic fingerprint and drag the cut to see the dendrogram, the clustering and the map recolour together. Radar fingerprints for each group make background and impact easy to show a regulator.
- Salinity fingerprints for every sample
- Dendrogram, clusters and map linked
- Evidence for background-adjusted guidelines
See every sample's chemistry in 3D. Similar sources cluster together.
UMAP places every sample in a 3D space by its full chemical profile, so samples from the same source fall together and outliers stand out. Fixed settings mean the same data gives the same picture every time.
- Whole-profile comparison, not one chemical at a time
- Repeatable settings and seeds
- Clusters coloured to match the dendrogram
Profile every sample's PAHs. A source report card in one click.
Parent and alkylated PAH profiles, diagnostic ratios and comparisons with reference sources come together in one report card that calls the sample petrogenic or pyrogenic and shows the evidence behind it.
- Parent and alkylated PAH fingerprints
- Diagnostic ratios and reference matches
- A report card with the evidence attached
Case study · Sour gas plant closure
Natural background, shown with chemistry. $2.6 million saved.
A closure was headed for years of extra sampling and 17,000 m³ of excavation. Salinity fingerprinting across the site's own historical record showed naturally occurring background and supported adjusting the guidelines applied.
less excavation than the original plan
weeks to an approved closure plan
