“I was so impressed with the performance of TASK™ on three of my NAPL projects that I inquired about joining Tersus as a Technical Sales Representative. As a remediation engineer, I find the Tersus products and their technical and administrative support to be unequalled in the industry and look forward to the next opportunity to use their products.  I confidently recommend their products to my clients and colleagues."
