CTEH is now Onterris

CTEH is now Onterris describes itself simply: "CTEH (Center for Toxicology and Environmental Health) is now Onterris, delivering expertise in toxicology, environmental health, emergency response, and regulatory compliance." To AI engines like ChatGPT and Perplexity it is partially visible, scoring 6.4 out of 10, readable in places and missing in others.

On the page itself the strengths are clear: a clear heading structure, visible credibility markers, crawler access and the files AI engines look for and sitemaps and entity links AI can follow. It is passable on some structured data and a partly stated business identity.

Away from its own site, other sites link to it. There is some, but not much, sign that the domain is only lightly established. Beyond that, AI engines do not yet recognise it as a distinct business, there is no press coverage to draw on, nobody is discussing it where AI engines look and it does not come up on Reddit. Those are earned elsewhere on the web, not fixed on the site itself.

AI crawlers have visited once in our tracking, including ClaudeBot (Anthropic). It does link out to several social profiles, which helps engines tie the brand together.
