Mundell’s client was concerned that the off-gas from an air stripper stack would be an odor nuisance to their employees. Mundell performed air dispersion modeling to demonstrate off-gas concentrations would remain below the odor threshold……Read More »

PLC Control Program Alteration
The operation of a remediation system was observed to be inefficient. The system’s logic program was actually damaging the equipment. The PLC control program for the system was written in such a way that when an alarm condition was detected, the system shut down for 10 minutes and then reset itself instead of remaining idle until manually reset by an O&M technician. Mundell wrote a new program to address these issues……Read More »
Remediation O&M – Efficient Cleaning of Airstrippers
Mundell transformed the all-day two person cleaning of airstrippers into an approximately 4 -hour one-person job using an acid re-circulation loop……Read More »
Groundwater Flow and Contaminant Transport Model Used to Evaluate Threat to Human Health and the Environment
Mundell undertook a modeling study at a site where the current remediation system had reached a point of diminishing returns to show that shutting off remediation would not result in further discharges……Read More »
Remote Remediation Alternative
At a remediation site and after detailed evaluation of various factors, Mundell employed six separate independent systems instead of one central system. This greatly reduced the costs that would be associated with moving the water from each well to a central location such as piping and trenching……Read More »
