BIOGRAPHY

Dr. Dietz has over 33 years of multi-disciplined consulting experience, including the past 18 years as an Environmental Engineer. He has experience in active and passive mine drainage treatment (R&D of new innovative anaerobic vertical flow wetlands); Clean Water Act National Pollution Discharge Elimination System (NPDES) studies; Clean Water Act Chapter 404 wetland protection and mitigation; and environmental and ecological assessments.

Combining his in-depth understanding of aqueous chemistry and mass transport processes with reactor design, Dr. Dietz has improved operation and performance at existing treatment facilities and has developed innovations in new full-scale treatment systems. Recently he has undertaken control and treatment projects related to Disinfection Byproducts (DBPs), which will become greater concern as state’s increase required chlorine residual in response to waterborne diseases.

In addition to his treatment operation and design experience he has extensive background in NPDES permitting and NEPA documentation bringing full service experience and capabilities to wastewater and water treatment. He has developed conceptual and preliminary designs for leachate collection systems and leachate and cooling water treatment facilities that included identification, testing, and use of innovative treatment technologies. He has also conducted several leachate treatability studies related to NPDES effluent limit compliance. Treatability studies include evaluation of chemical/physical processes including chemical neutralization, oxidation/precipitation, coagulation/flocculation, sedimentation, and filtration.
