Toxicity Identification Evaluation (TIE) Evaluation

Example of a Toxicity Identification Evaluation Plan

TIE testing is performed when a facility is seeing consistent results indicating toxicity and has not been able to determine the cause.  This can be difficult because 1) multiple potential toxicants may be present, 2) little or no toxicity data exist for many compounds, 3) toxicity is frequently variable, and 4) the sample matrix may greatly modify toxicity. By working closely with site personnel and engineers we have assisted numerous facilities identify the causative toxicant so that appropriate treatment and/or management options could be instituted and toxicity reduced or eliminated.

 

We can tailor a TIE which incorporates identification methods appropriate for the specific situation and thus provides the most economical and expeditious solution to the toxicity problem.
