Remediation by Natural Attenuation
RNA is an effective, viable remediation process that is active at virtually every site. In Aqua Veritas, LLC personnel were actively involved in the development and roll-out of ASTM's RNA guidance document (E-1943-98), have developed internal RNA guidance for major petroleum clientele, and are well versed in a wide variety of additional RNA protocols, such as the Monitored Natural Attenuation programs endorsed by the EPA and the US Navy, among others.
Let IAV guide you through the RNA implementation process:
- First Line of Evidence - is RNA already effective at your site, and will it achieve remedial goals?
- Second Line(s) of Evidence - what are the rates of remedial progress through RNA at your site? Which TEAs are effective, and would augmentation be of any use?
- Aerobic/Anaerobic processes - is oxygen injection or infusion the answer?
- RNA Work scopes - determine realistic remedial goals, sampling and monitoring strategies for your sites.
- Exit Strategies - can you close your site with RNA, or will active remediation be required within a RBCA/RNA management framework?
- Finally - Oxygenates. RNA's sleeping dragon. What are your options if your site has high concentrations of MTBE, TBA or similar compounds?
There's not much...
..that microbes won't gladly have for lunch. Like your kids, though, there are some things that they like better than others. Does your site have the bacterial world's equivalent of broccoli or fudge sundaes? Knowing the difference could lead to significant savings by avoiding or limiting more active and/or intrusive remediation methods.
