Mr. Pittenger joined the in-situ remediation services firm ISOTEC in late 2020. He is part of the senior leadership supporting technical remedial solution development, bench study design, large project management, and staff mentorship. Prior to ISOTEC, Scott worked for fifteen years as environmental consultant for AECOM, Earth Tech, and other smaller firms. His most rewarding responsibilities while consulting included building and managing an in-house treatability studies laboratory and supporting projects internationally in a design capacity or in a technical advisory leadership role. Bench design and study work translated directly into field implementation. The lessons learned performing both duties informed a deeper understanding of remediation design and strategy and contributed to successful projects in a variety of environments (e.g., US, Canada, Mexico, Italy, Germany and Isreal). His comprehensive design/construction experience includes AS/SVE/DPE/P&T, ISCO, ISCR, bioremediation, phytoremediation, landfarming, and dig/haul.

Scott migrated to the client side in his next role as an environmental remediation manager for 8 years at Norfolk Southern Railway, with management responsibility for half of the corporations’ environmental remediation liabilities. Regularly, Scott met with state regulators in eight states comprising his territory, negotiating site cleanup goals and advocating for reasonable solutions. He provided strong environmental risk management decision making to internal customers: real estate, accounting, industrial development departments and was integral to the review of contracts, large real estate transactions (e.g., built and led due diligence team as part of the $217 million acquisition of D&H Line). Teaming with excellent consulting partners, a good cup of coffee and a large paper napkin, Scott conceptualized and implemented a novel corporate sustainable remediation program.

Scott has a Bachelor of Science in Biology from the University of South Florida and has spent a career proving biologists from far afield bring a unique set of skills to the remediation industry. When he is not ruminating on remediation, he can be found catching up on the latest doings of his two young adult sons or planning a new adventure with his wife.
