Summary of Experience 
With over 35 years in the environmental industry, my experiences have afforded me the chance to participate in a wide variety of environmental investigation, remediation and management projects. Responsibilities have included waste water treatment plant chemist/operator, college Human Anatomy instructor, to the design, implementation and oversite of private-government sponsored remediation projects. In 2008 I began working to developing and work with in-situ and ex-situ bioremediation; and in 2008 I established TerraStryke Products LLC, providing biostimulation additives designed to leverage existing site conditions and native microbial populations to realize safe, low-impact, cost-effective, destruction of soil and groundwater contaminants.


Successful ERDenhancedâ„¢ pilot evaluation using simple additive delivery approach leads to full-scale biostimulation strategy for destruction of residual chlorinated volatile organic compounds (CVOC)

Site with pump and treat systems becoming asymptotic yet concentrations of Trichlorethylene (parent cVOC) at saturation, significant residual mass present. Discussion of use of carbon-carbohydrate based additive containing proprietary nutrient formulation to realize extended (8+years) destruction of DNAPL contaminants (>98% molar destruction) by indigineous dehalorespiring bacteria after single deployment of minimal additive volume. Area of remedial influence observed 65-feet downgradient from anticipated influence extent. As of date of submittal, reducing conditions and contaminant destruction continues with no additional deployments and/or adverse side effects regarding ambient air concerns. Discuss need to look at remedial strategies holistically and the treatment zone as a stressed ecosytem with limiting factors preventing maximum microbial performance and development. In doing so, ancient anaerobic principals will dictate, syntrophic relationships between degraders and fermentors will establish, biofilm development allows protection and microbial communication and information sharing to effectively increase bulk fractions and capabilities of the indigenous dehalorespiring bacteria.
