GLP Asphalt LLC

“Environmental Science International did remarkable work on the project considering that the proposed facility was the only one of its type built in the United States in recent years with no others under construction or contemplated. The uniqueness of an asphalt terminal required a very high level of coordination amongst the various disciplines for which ESI was well suited. The end result of the process was a petroleum terminal constructed in 2 ½ years from concept to operation which was directly the result of the work of ESI.”

Hawaii Department of Health, HEER Office

"Just wanted to send a short note to restate what a great job ... I think the ESI team is doing on the ConocoPhillips site in downtown Honolulu. We are already using your work to help guide preparation of our upcoming, revised Technical Guidance Manual and Environmental Hazard Evaluation (EAL) document. My guess is that you're going to shave at least a year off of the time it would normally take to get a site like this investigated, evaluated and cleaned up. The site investigation report we received this week is in particular one of the best we've ever seen and will expedite our review of the site data immensely, saving everyone time and money in the long run. "

I have found their technical capabilities to be outstanding, as is their ability to deliver high quality environmental services. The timeliness of their work is also outstanding; when new aspects of a project arise, as they often do with this type of work, ESI has always been very responsive and approachable in meeting our needs."
