Who We Are

In the mid 1990’s, Environmental Analysis South began providing acute whole effluent toxicity testing to their clients.  Today, we primarily specialize in wastewater, stormwater, pretreatment discharge water and drinking water utilizing approved US EPA methodology. 

Our main goal is and always has been to provide personal service, education, and accurate results to our clients.  Our staff will strive to provide a service that is fair, always being aware of our clients’ compliance needs, and never to compromise our client’s reputation and our integrity.
