AISCT® Technical Resource Library & Field Operations Bulletins.

Most of what gets called AI in this industry reads data someone else already collected. Physical AI does something different: it goes to the site, produces the measurement itself, and is judged on whether the ground agrees.

The most useful thing a field instrument can tell you is not what the soil contains. It is how much the soil moves when you sample it twice.

Regulators described this way of working thirty years ago. The industry agreed with it, and then carried on doing something else. The reason is more interesting than it looks.

Three instrument families, three different failure modes, one root cause. None of them is a criticism of the people using them.

The beliefs that keep field data in the margins of a project are rarely stated out loud. They are worth stating, because most of them do not survive contact with the evidence.

A field screening result is not a cheap laboratory result. Understanding what it is for — and how to judge whether it is working — changes what you can do with it.

The AISCT® Sal™ System — part of TRIUM's Artificial Intelligence Site Characterization Technology platform — is a field screening system for salt-impacted sites.

he AISCT® Petro™ System — part of TRIUM's Artificial Intelligence Site Characterization Technology platform — is a field screening system for extractable petroleum hydrocarbons in soil.

The AISCT® Aurora™ System — part of TRIUM's Artificial Intelligence Site Characterization Technology platform — is a field screening system for volatile organic compounds, chlorinated solvents and petroleum hydrocarbons in soil.

Eight vapour screening programmes, 662 laboratory-paired soil samples, one question: does the field reading actually predict what the laboratory will report?

These fourteen habits are the difference between a screen that carries your decisions and one that produces numbers nobody can defend.

The number arrives in the same units as your limit, on the first sample of the programme. What is left to get right is the procedure — and the record that proves you followed it.
