Meet David T. Johnson, P.E. ...
I am a chemical engineer with over 25 years of experience providing providing chemical engineering services to industrial and government clients. I have been a consultant for the last 12 years and have been in independent practice since September, 1996.
I have developed a wide variety of pretreatment systems for industrial wastewater and hazardous waste. I have also designed manufacturing process systems for chemical plants and oil refineries. I have successfully completed treatment systems used in RCRA closures, CERCLA site remediation, and industrial manufacturing.
I have also performed extensive work to help industrial clients obtain or maintain effluent permits. Spill prevention planning, pollution prevention planning, and waste minimization studies are other services that I have provided to recent clients.
