With 34 years of environmental remediation experience, I created NX-Situ Remediation to better service my clients by closing sites with the lowest life-cycle cost and addressing the following issues:
I have designed systems and implemented technologies to close 35 sites in the US (19) and Australia (16). I have been a key individual for in-situ chemical oxidation (ISCO) in Australia by establishing a way for Australians to purchase the strongest oxidant (sodium persulfate) while accounting for international patents and royalties. I was also the first individual to implement ISCO in Australia with sodium persulfate on petroleum while honouring patents.
I have also implemented many technologies to close sites – some with performance-based contracts. During my entire career I’ve focussed on remediation. I’ve worked with some of the best companies and brightest people to close sites. I find nothing more appealing in my profession than to get a site off the books.

Denton has an unmatched passion for remediation and it has been a pleasure working with him. Through our experience on the Remediation Community of Practice, I was reminded of what drew me to this industry to start with.

I’ve worked with Denton off and on since 1989 and in a professional capacity, there are few engineers with his dedication to sound and effective environmental remediation solutions. Even in personal life, his commitment to the environmental industry and the environment as a whole permeates his being. Denton is congruent in all that he does and that is the highest form of trust and why I am happy to recommend him.
