Mr. Walker has been involved in the environmental industry for over 30 years. His career began in 1986 working for W.R. Grace in Nashua, NH. His work involved plant wide point source testing, operation of the facility 0.35 MGD wastewater treatment plant, NPDES permit monitoring, lab chemistry and incident response team. He also held a chemist position for a commercial laboratory focused on wastewater and soils characterization. He also worked as a business development manager working with clients on complex site characterizations and testing requirements to properly identify pollutants of concern. He expanded upon his prior laboratory experience and was instrumental in performing ‘unknown’ waste characterizations on many Region 1 and Region 3 ERCS sites. Mr. Walker provided bench study data on precipitation and removal of cadmium from a plating lagoon which significantly reduced the treatment and disposal costs of the wastewater effluent at the cleanup of the site saving an estimated $250,000. Since 1996 Mr. Walker has been engaged in the management and support for both industrial and municipal clients focused turn-key services for NPDES, IDP and Groundwater discharge permits in New England.
