ETT is an environmental  laboratory and consulting firm providing environmental testing,  with a 

focus on  identification and resolution of   wastewater toxicity problems. In  this  new  millennium,

environmental protection of our nation's waters will rest on three approaches to monitoring; toxicity

testing, in-stream assessments of aquatic fauna, and traditional chemical analyses. ETT functions

at the crossroads of these approaches, and by bringing our expertise to integrate them together

provides the most comprehensive approach in solving environmental problems.

ETT is a multi state certified laboratory and participates in EPA DMR-QA performance evaluation

studies. We are certified by states of South Carolina (SCDHEC), North Carolina (NCDENR), and

Florida (FLDEP).
