Steve is the President and co-founder of ECT (Emerging Compounds Treatment Technologies). ECT is an equipment company focused on developing and commercializing treatment technologies for emerging, difficult-to-treat contaminants.

Steve’s focus is currently on commercializing Synthetic Media technologies for the sustainable treatment of PFAS, 1,4-dioxane, and other emerging contaminants. He received his Ph.D. in Environmental Engineering from Purdue University in 1992.


Optimized Treatment of 1,4-Dioxane in Extracted Groundwater and Reinjection for Aquifer Replenishment

A long-term groundwater pump & treat system has been operating in Santa Fe Springs, CA since the late 1980’s for hydraulic containment of chlorinated volatile organic compounds (VOCs). Detection of up to 60 micrograms per liter (µg/L) of 1,4-dioxane as an emerging contaminant resulted in the installation of an advanced oxidation process (AOP) with a granular activated carbon (GAC) polish system. The now aging treatment system has suffered from increasing O&M costs and unpredictable breakthrough of 1,4-dioxane. A lifecycle cost comparison was conducted to evaluate the potential savings associated with replacing the system with an AMBERSORBTM 560 (Ambersorb) resin treatment system, based on its simpledesign and low operating costs.

The AOP/GAC system was replaced by Ambersorb, based on the results of the lifecycle cost comparison. This eliminated the desorption of 1,4-dioxane from the GAC polisher and high maintenance cost of the ozone generator. After 18 months of operation, the full-scale Ambersorb system continues to consistently produce non-detect effluent for 1,4-dioxane and VOCs. Resin regeneration frequency has only occurred only once every 3 months, on average, contributing to substantial O&M cost savings.
