NX-Situ Remediation Pty Ltd

Closing difficult sites with the lowest life-cycle costs!

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:

  • PFAS – Need help with treating or disposing of PFAS-contaminated soil and groundwater?
  • Difficult Site – Do you have chlorinated solvents or recalcitrant contamination that appears to be too difficult to remediate?
  • NAPL Management – Have solutions been proposed that will address non-aqueous phase liquid (NAPL) issues?  Are you using adsorptive socks to recover NAPL and have been doing so for more than a year?
  • Evaluating past remediation performance – Did past performance work as designed and can existing infrastructure be enhanced to improve remedial performance?
  • Source evaluation – Has the residual source been evaluated to assess long-term impacts on the plume longevity?
  • Passive remediation evaluations – Have proposed passive remediation options been evaluated and compared to current innovative technologies?  Are estimated active remediation efforts accurate?
  • Life-cycle estimates – Has a Monte Carlo simulation been performed to account for probability distributions of variables to develop a probability of cost?

Why Hire NX-Situ Remediation?

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.

Testimonials

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. 

~Tara Byra, Kleinfelder 

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.
